SeaBeacon® 2 System 6 General Information

Tideland Signal Corporation 1 0111181-00 Rev A 08APR09 General Information.doc

CHAPTER 1 GENERAL INFORMATION

1.1 GENERAL DESCRIPTION

A marine radar displays a picture of all objects that reflect pulses within the service range of the radar. The objects displayed usually represent either hazards to navigation or guidance devices that have been deployed to assist in course determination. When there are many returns from individual target, the exact identity and location of the displayed radar targets helps to reduce the risk of disastrous navigation errors.

The SeaBeacon 2 System 6 racon provides the mariner with precise navigation information in the form of a coded trace on the radar screen that can readily be identified as specific to a particular racon. The coded trace identifies and fixes the position of the racon with respect to other targets. When used in conjunction with navigation charts showing the identity and location of the racon, this trace aids in the correlation of other targets with their chart markings. Thus oriented, the mariner is able to achieve precise vessel positioning in all weather and visibility conditions.

Marine radar beacons “racons” are designed to respond to marine shipborne X and S band radars. Due to similarities between marine and aviation radars, aviation radar may receive responses from marine racons but there are no established international standards for this type of application and our equipment is not designed to operate under these conditions. Tideland does not recommend using our SeaBeacon racon product line as a radar beacon for aviation traffic.

1.1.1 Functions of the SeaBeacon 2 System 6 Racon

The SeaBeacon 2 System 6 racon is an all-weather aid to marine navigation that responds to radar pulses. The racon is a transponder that receives a radar pulse from an interrogating radar transmits a coded response. The presence of that response on the radar display provides the mariner precise information regarding the identity and location of the racon because each racon can be set to produce a specific Morse code character. The racon can be used to provide range and bearing information.

The SeaBeacon 2 System 6 racon is frequency agile, which means that it responds at the same frequency as the pulse from the interrogating radar. Moreover, the length of the coded racon response of the radar display is scaled to be proportional to the interrogating radar pulsewidth. One can alternatively select the SeaBeacon 2 System 6 racon to provide a fixed length response. Digital signal processing techniques and high speed circuitry employed in the SeaBeacon 2 System 6 racon enable it to reply to several hundred vessels in its service area.

The ideal marine radar would have a narrow, well defined beam (main lobe) with energy radiating only from the main lobe. In practice, radar antennas radiate a small amount of energy in directions outside the main lobe. These secondary beams are called side lobes and, if responded to, are a possible source of confusion when the racon is close to the interrogating radar. Should a racon respond to a side-lobe pulse from a nearby vessel, multiple traces would be painted on the



radar display, and the radar operator would not know which of those traces represented the actual racon position relative to the vessel.

At some locations, the geography of the racon installation site is such that side lobes are not a concern for racon operation because vessels are unable to approach close enough for side lobes to trigger a racon response. At other locations, side lobes have a significant effect on racon operation. The side-lobe suppression feature enables the SeaBeacon 2 System 6 racon to discriminate between pulses from the main lobe and those from the side lobes of the same radar. The racon is inhibited from responding to side-lobe pulses.

Any of the pre-programmed Morse code characters beginning with a dash (shown in Table 1.1) can be used to identify the racon. The choice of code and of code character length is made by means of an external handheld keypad or computer terminal.

Table 1.1 Racon Codes



1.1.2 Mechanical Features

The major assemblies of the racon are a base housing/chassis assembly that contains the electronics, the X-band and S-band antennas, and a radome that provides weather protection for the antennas.

The base housing is cast from marine grade aluminum. On the outside, the housing is painted with Corthane enamel. The radome is attached to the housing and sealed by means of an airtight O-ring. This arrangement protects the internal assemblies from saltwater intrusion. Sealed cable connectors assure submersibility at water depths up to 10 meters (35ft.).

The reliability of the circuit interconnections is enhanced by the use of a printed circuit back plane and connectors with gold-plated contacts.

The radome is made from gray polycarbonate structural foam, a material that is highly transparent to microwave energy and remain stable under ultraviolet radiation. The exterior of the radome is coated to seal the structural foam and painted with polyurethane enamel.

1.1.3 Input Power Requirements

The SeaBeacon 2 System 6 racon requires and input voltage of 9 to 36 volts DC that can be supplied by several types of DC power sources. An AC-powered battery charger and storage battery combination is a reliable method of obtaining unlimited power to operate the racon. In remote locations where AC mains power is not available, the racon can be powered by a photovoltaic generator coupled to a 12 volt or 24 volt battery. Under all conditions, the effective source impedance of the voltage supply must be less than 0.05 Ohm.

Under limited-power conditions, racon power consumption becomes an important factor. The power management feature of the SeaBeacon 2 System 6 racon ensures minimum power consumption.

For power consumption figures see Appendix A.

Chapter 2 Installation

2.1 INITIAL INSPECTION

Initial inspection of a SeaBeacon 2 System 6 racon is a three step process: receiving, unpacking, and visually inspecting the racon.

Receiving:

When the SeaBeacon 2 System 6 racon arrives, make note of any physical damage to the exterior of the shipping container. Exterior damage may be the only clue to possible interior damage caused by rough handling in shipment.

Unpacking:

Unpack the racon carefully without damaging the shipping container. The container has custom designed cavities that conform to the shape of the racon. Save it for future use in shipping the racon.

Visual Inspection:

After the unit is unpacked, visually inspect the racon for obvious damage. Check that all associated hardware is accounted for and damage free.

2.2 INSTALLATION MATERIALS SUPPLIED

Table 2.1 identifies the contents of the shipping container. All materials required for normal installation are included in the shipping container. At some sites there may be a need for a mechanical lifting device to position and hold the racon in place prior to installing the mounting hardware.

2.3 INSTALLATION CONSIDERATIONS

In planning the installation of a SeaBeacon 2 System 6 racon, consider the requirements for level installation, proper orientation of the racon, and possible obstructions to its operation.

NOTE: All pre-installation adjustments are performed in the factory. Further adjustments prior to installation in the field are not necessary.

Site:

The racon must be leveled. For fixed mounting surfaces, install the racon within a few degrees of true vertical. For installation on buoys, just mount the racon upright.

For best results, locate the racon as high as practical in order to provide a clear line-of-sight path between the racon and the marine radar. In general, the higher the racon is mounted, the better is its useful range.

For example, a ship’s radar antenna is 15 meters (50 ft) above water, and the highest point of land the vessel is approaching is 91 meters (300 ft) resulting in a nominal radar range of approximately 28 nautical miles.

� �TRTXNM HHR �� 08.2R is in Nautical Miles

HTX and HTR are Heights in Meters

For more information about racon range estimates, please see the latest IALA publication “Guidelines on Racon Range Performance”.

Orientation:

The racon must be mounted vertically. The orientation arrows on the lift ring (opposite the connectors) should point seaward or toward the longest range of the traffic service area.

Record of Obstruction:

Create a record of the installation that notes the date of the installation and any obstructions that exist between the racon and the sea lanes where ship traffic of interest will pass. Retain this record and refer to it periodically to determine whether any new construction is interfering with the racon performance to the extent that relocation may be advisable.

2.4 MECHANICAL MOUNTING PROCEDURES

The racon can be mounted either on a flat and level surface with 4-hole mounting or on a non-level or non-flat surface with 3-hole mounting; however, the racon itself must be leveled. If the mounting surface is level, follow the procedure below to mount the racon. If the mounting surface is not level, follow the alternate procedure to non-level mounting surfaces.

Level Mounting Surface:

Follow the steps below to mount a racon onto a flat and level surface. Refer to Figures 2.1 and 2.2 for mounting details and mounting hardware.

WARNING To avoid personnel injury, use care in standing on the racon support structure. The footing on the support structure may be covered with the slippery marine growth. DO NOT use the racon as a step-up ladder. The housing will not support your weight.

1. Locate the leveling/mounting kit (P.N. 901.1042-00). See Figure 2.2 to identify the mounting hardware required for level mounting.

2. Drill four 13 mm (0.5 in) diameter holes in the mounting surface (pedestal or flange) to which the racon will be affixed. In the plastic sleeve at the back of this manual is a 1:1 drawing for use as a template for drilling the holes (see Tideland drawing 901.1042-00, sheet 2 of 2).

3. Using the lift ring provided, lift the racon and set it on the mounting surface so that the holes in the racon base are aligned with the holes drilled in the mounting surface. To simplify hole alignment, use one or two mounting bolts as temporary alignment pins.



8

4. Insert a hex head bolt (see Figure 2.1), first through the racon base and then through the mounting surface. From underneath the mounting surface, install a flat washer, a split-lock washer, and a hex nut on the head bolt. An optional hex nylok nut may be added (see Figure 2.2).

5. The earth ground connection for lightning protection is made on a stud mounted on the racon base housing mounting flange.

CAUTIONThe Ground Strap must securely connect to a earth ground for lightning protection.

6. Tighten the nuts in the alternating bolt fastening sequence shown in Figure 2.1 to an initial torque of 13 + 2.5 N-m (10 + 2 ft lb).

7. In the same sequence, tighten the bolts to a final torque of 40 + 2.5 N-m (30 + 2 ft lb).

Non-Level Mounting Surface:

Follow the steps below to mount a racon on a non-level or not flat surface. Refer to Figures 2.1 and 2.3 for mounting details and leveling hardware.

1. Locate the following items required for leveling:

· Leveling/mounting kit (P.N. 901.1042-00)

· Carpenters level (1 each)

· Open-end wrench, 17 mm (2 each)

2. Drill three 13 mm (0.5 in) diameter holes in the mounting surface (pedestal or flange) to which the racon will be affixed. In the plastic sleeve at the back of this manual is a 1:1 drawing for use as a template for drilling the holes (see Tideland drawing 901.1042-00, sheet 1 of 2).

3. Using the lift ring provided, lift the racon and set it on the mounting surface so that the holes in the racon base are aligned with the holes drilled in the mounting surface. To simplify hole alignment, use one or two mounting bolts as temporary alignment pins.

4. Assemble the leveling bolts as shown in Figure 2.3. Insert a hex head bolt through the racon base (see Figure 2.1). From underneath the racon base, install a flat washer, a split lock washer, two hex nuts, an exterior star lock washer, a hex nut, and a flat washer. Insert this bolt assembly through the mounting surface (position 1). From underneath the mounting surface, install a flat washer, a split-lock washer, and a hex nut. An optional hex nylon nut may be added (see Figure 2.3).



9

5. The earth ground connection for lightning protection is made on a stud mounted on the racon base housing mounting flange.

In the same manner, install the other two leveling bolts in positions 3 and 5 (see Figure 2.1).

6. Tighten the top nut of each bolt assembly against the mounting flange of the racon to a torque of 11 + 0.7 N-m (8 + 0.5 ft lb). This will secure the hardware to the racon.

7. Visually level the racon by adjusting the bottom and middle nuts as required.

8. Place the carpenter’s level on the X-axis of the racon lift ring.

9. Adjust the hardware as required until the bubble is centered within the marked circle.

10. Reposition the level to the Y-axis and adjust the as required to center the bubble.

11. Recheck the X-axis and adjust as required.

12. Repeat steps 7 through 10 as required.

13. Using the tightening sequence shown in Figure 2.1, tighten the two bottom nuts of each bolt assembly to a torque of 40 5 2.5 N-m (30 5 2 ft lb) and recheck level of racon.

CAUTION

The Ground Strap must securely connect to an earth ground for lightning protection.

2.5 ELECTRICAL CONNECTIONS

2.5.1 DC Power Cable Limitations

The SeaBeacon 2 System 6 racon must have a minimum 9VDC input at the connector terminals in the racon base housing to operate properly. This means there is a practical limit on the total cable run from the battery to the racon, especially for 12VDC batteries.

The power cable run consists of two sections of cable: the cable P.N. 510.1235-00 (or -01) that ships with the racon, and a second cable between the racon junction box or distribution box and the battery, whose length and size is usually determined by the installer.

2.5.1.1 12 VDC Power System

The Tideland cable uses #12 AWG copper wire for power conducters. Assuming a worst case peak instantaneous current of 4A in the cable, and a loaded battery voltage of 11.0VDC (based on a nearly discharged battery), the overall allowable cabling loss is 2.0V. Assuming a safety factor of 0.3V for miscellaneous losses in field connections, the design loss in all of the copper wiring must be limited to 1.7VDC at 4A. The 4.5 meter Tideland cable P.N. 510.1235-00 will contribute a loss of 0.2V.

1.7 - 0.2 = 1.5V

The 15 meter version of the Tideland supplied cable (P.N. 510.1235-01) will contribute a loss of 0.7V. The remaining allowable loss in the other cable is then:

1.7 - 0.2 = 1.5V, when 4.5 meter cable is used, and 1.7 - 0.7 = 1.0V, when the 15 meter cable is used

Table 2.2 shows cable limitations for connecting a 12VDC battery to the racon junction box.

2.5.1.2 24 VDC Power System

Assuming a loaded battery voltage of 22.0VDC (based on a nearly discharged battery), the overall theoretical allowable cabling loss is 13.0V. However, Tideland recommends limiting the practical overall cabling losses to 4.0V maximum for optimum operation. Assuming a safety factor of 0.3V for miscellaneous losses in field connections, the design loss in all of the copper wiring must be limited to 3.7 VDC. The minimum input voltage at the base housing of the racon is then approximately:

22.0 – 4.0 = 18.0VDC

At 18VDC, the worst case peak instantaneous current in the cable is 4A. The 4.5 meter Tideland cable P.N. 510.1235-00 will contribute a loss of 0.2V. The 15 meter version of the Tideland cable P.N. 510.1235-01 will contribute a loss of 0.7V. The remaining allowable loss in the other cable is then:

3.7 – 0.2 = 3.5V, when the 4.5 meter cable is used, and 3.7 – 0.7 = 3.0V, when the 15 meter cable is used

Table 2.3 shows the cable limitations for connecting a 24VDC battery to the racon junction box.

The following steps explain how to make connections when using Tideland junction boxes or distribution boxes.

1. The standard junction box for the SeaBeacon 2 System 6 racon is the JB-5R Junction Box (P.N. 630.1169-00). If the racon is to be used with blanking (Inhibit) of more than one source or communications, however, it requires the DB-5P Distribution Box (P.N. 630.1187-06). Determine which box is to be used with the system and refer to the associated figure and connection table on the following pages.

2. Locate the appropriate box and mount it. See Figure 2.8 for JB-5R mounting dimensions and Figure 2.11 for DB-5P mounting dimensions.

NOTE: The power and data cable supplied (P.N. 510.1235-00) is 4.5 meters (15ft) long.

3. Pass the racon power and data cable through the appropriate gland and terminate the wires as shown in the appropriate figures and tables (Figure 2.7 and Table 2.4 for the JB-5R, or Figure 2.10 and Table 2.5 through 2.8 for the DB-5P). For the JB-5R box, install the crimp-on terminals provided before terminating the wires to the terminal strip. Tighten the gland nut securely.

4. Connect the DC power line and all other lines to options according to the wiring diagram for the box used. For the installation of the blanking or the GO/NO GO option, refer to Section 2.6. If possible, install a disconnect switch for the DC power line at the power source. With a disconnect switch installed, turn the power off. If a disconnect switch cannot be installed, use care when connecting the power and data cable to the racon. Do not proceed to step 5 until the racon is ready to be energized. Securely tighten all gland nuts.

5. NOTE: Inside the P1 cable connector shell, check that a bead of light colored grease is visible on the inside bottom of the connector. When shipped from the factory, the P1 cable has marine grease applied for moisture protection. If the P1 cable is being reconnected, then a small amount of Non-conductive Marine Grease (PN 4031018-00 Old Bull Mold Grease) must be applied to the outer rim of the base housing connector (J1). For more detail, see 011.1210-00 Operation and Maintenance Manual.

Remove the dust cap from the bulkhead connector (J-1) on the racon (see Figure 2.1). Retain the dust cap for later use if the racon should have to be shipped. Connect cable connector P-1 (Figure 2.5) to the bulkhead connector. Mate the connectors and apply moderate force until they seat. There will be some resistance because the connection is designed to be watertight. While pushing cable connector P-1 into place, rotate the locking ring clockwise. Hand-tighten the locking ring until it is flush with the base of J-1.

6. If you turned the power off in step 4 above, now turn it on. At this point, the racon is ready to operate.



19

7. When the power is applied to a System 6 racon, the software performs a number of self-test operations on the hardware. One of the first devices to be tested is the internal beeper (short beep). After a few seconds, the software will test a circuit (the “watch dog” circuit) that automatically restarts the racon in case of failure. During the restart, the software will again test the beeper (short beep). After completion of this part of the tests, the software will calibrate the racon. Calibration takes a few seconds. Once all the tests and calibration are complete, the racon enters into its normal power management cycle. The racon will indicate when it goes into the active mode of its cycle by using the beeper. The beeper will sound one of two codes, depending on results from self-test calibration. The Morse A code (short beep, long beep) is used to indicate there are no errors. The Morse O code (three long beeps) is used to indicate an error. While there is an error, the racon’s GO/NOGO signal will indicate NOGO. Using the handheld terminal or any computer, the source of the error can be determined (Function 6, Selftest, Section 3.3.3. User Functions).

NOTE: The power input to the racon is completely protected internally from reverse polarity, high voltage, power surges, lightning, and AC ripple.

It is imperative that the grounding strap has a secure connection to earth ground.

A suitable connection that can sustain adverse effects from the environment (temperature, humidity, vibration, shock, and salt spray) is required.

The resistance from the metal terminal at the base must be less than 1 Ohm to earth ground.

CAUTION

The Ground Strap must securely connect to a earth ground for lightning protection.

2.6 INHIBIT AND STATUS DISPLAY

2.6.1 Inhibiting Racon Response to Fixed Radar

Racon responses may interfere with fixed local radars that are in the area (such as VTS equipment). Inhibiting can be used to eliminate an undesirable racon reply. To use this function connect an inhibit control signal from the fixed local radar to the racon. The inhibit signal should have the characteristics shown in Figure 2.12.

Figure 2.12 Inhibit Pulse Characteristics

The inhibit signal is connected to the SeaBeacon 2 System 6 racon by means of the INHIBIT (+) (brown wire) and the INHIBIT (-) (blue wire) lines of the power and data cable (P.N. 510.1235-00).

The inhibit signal is driven from an external source of +5V to +12V pulses from a local radar. These signals are to be connected to the INHIBIT (+) with a return connected to INHIBIT (-). The pulses should go active about one microsecond before the radar begins transmission and remain till about one microsecond after the transmission has ended. The input to the inhibit circuit is a NEC PS8701. The NEC PS8701 is an optically coupled isolator containing a GaAIAs LED on the light emitting diode (input) side and a PIN photodiode and a high speed amplifier transistor on the output side. Typical ratings are VF = 1.7V at IF = 16mA (max), VF = 1.6V at IF = 1mA for the LED. The LED has 520 ohms of external resistance in the anode circuit and 50 ohms in the cathode circuit for a total of 570 ohms of series resistance added see Figure 2.13.

The JB-5R junction box is simply a metal housing with a terminal strip. All external circuitry will need to be provided by the customer or owner to implement inhibit from the fixed local radar. The DB-5P distribution box includes circuitry to drive the inhibit circuit from one or two radar sets. The inputs to the DB-5P distribution box may be by N type connectors or by terminal strip connections.

32

2.6.2 Status Display

The status display lines (GO/NO GO + and -) provide a means of continuously monitoring whether or not the racon has passed its self test. Figure 2.14 shows a functionally equivalent circuit along with a possible method for implementing the GO/NO GO function. The circuit can switch an outside current source of 125mA or less.

The polarity or signal sense that the SeaBeacon 2 System 6 racon provides, is user selectable. The opto-isolator is normally turned on only if there is a racon malfunction. This method minimizes supply current.

The output of the GO/NO GO circuit is a NEC PS2702-1 optically coupled isolator containing a GaAs light emitting diode and an NPN silicon darlington-connected phototransistor. There are two 50 ohm resistors, one on the GO/NO GO (+) and the other on the GO/NO GO (-), and a 1N4148W diode in series on the GO/NO GO (+) see Figure 2.14.

Figure 2.14 The GO/NO GO Circuit

The DB-5P distribution box contains a GO/NO GO relay with a form C contact output. Either a normally closed or a normally open contact, rated at 1 amp /120 Volt maximum AC or DC, may be selected.

2.7 DISMOUNTING AND SHIPPING THE RACON

In the event the racon needs to be returned to the intermediate repair facility for maintenance, use the following procedures for dismounting and shipping the racon.

CAUTIONTo prevent damage to the racon, do not under any circumstances break the seal of the racon in the field.



33

2.7.1 Dismounting

The dismounting procedure is the reverse of the mounting procedure. Disconnect the electrical connections first, and then remove the mounting hardware and retain it with the racon. 2.7.2 Preparation for Shipment

Place the dust cap on the bulkhead connector J-1 on the racon. The shipping container for the racon has internal cavities that conform to the shape of the racon. Use the original shipping container to pack the racon for reshipment.

2.7.3 Shipping

Should the SeaBeacon 2 System 6 racon need to be returned for any reason, obtain a Return Material Authorization number from Tideland prior to shipping. Contact your nearest Tideland representatives for instructions.

Facilities authorized to repair the SeaBeacon 2 System 6 racon are listed in Chapter 1, Section 1.2.

3.4 PURGING AND REPRESSURIZING

The SeaBeacon 2 System 6 racon is normally pressurized at the factory to prevent moisture intrusion.

This section defines maintenance requirements for preventing moisture intrusion over the life of a pressurized or unpressurized racon.

3.4.1 SeaBeacon 2 System 6 Racon

The racon base housing/chassis assembly is pressurized at the factory with pure dry nitrogen to 35 + 5 kPa (5 + 1 psig) to protect the internal electronic components from moisture intrusion.



43

The racon should be purged and repressurized periodically to ensure sufficient gas pressure. The required purge kit is available as Tideland P.N. 901.1058-00. To perform the purge procedure, you should have a cylinder of dry nitrogen gas, an adjustable pressure reducing valve, and adapters to connect the pressure reducing valve to the gas cylinder.

The pressure reducing valve should have an inlet pressure range of 21,000 kPa (3000 psig) and a maximum outlet pressure of 205 kPa (30 psig). The reducing valve should be equipped with inlet and outlet pressure gauges of the appropriate ranges. The connection to the purge manifold is 0.25 inch NPT male thread. Figure 3.2 depicts the connection of the purging equipment to the racon.

Perform the following purging and repressurizing procedure once a year to ensure that the racon is sufficiently pressurized.

3.4.2 Purging Operation

1. Assemble the purge kit components, the pressure reducing valve, and the gas cylinder as shown in Figure 3.1. Do not connect the manifold outlet hose to the adapter fitting at this time.

2. Remove the cap covering the purge inlet fitting and carefully connect the adaptor fitting to the purge inlet.

3. Turn the adjustment knob on the pressure reducing valve to the minimum setting. Slowly open the gas cylinder valve until the inlet pressure gauge stops rising; then fully open the cylinder valve. Open the isolation valve on the purge manifold. Slowly increase the outlet pressure of the reducing valve until gas begins to escape from the manifold outlet hose. Allow the gas to flow at this slow rate for about 15 seconds. Then connect the hose to the adaptor fitting, which was connected to purge inlet in step 2 above. Increase the outlet pressure from the reducing valve to 35 kPa (psig), measured by the outlet pressure gauge on the reducing valve.

NOTE: The purge manifold is equipped with a relief valve to warn the operator of excessive pressure. If the relief valve starts venting gas, close the isolation valve and check the manifold pressure gauge. The relief valve provides only a warning of excessive pressure. It

CAUTION

While purging the racon, do not allow the pressure indicated on the manifold pressure gauge to exceed 138 kPa (20 psig). Internal pressure of more than 138 kPa (20 psig) could damage the racon housing and prevent the housing from sealing properly.



44

cannot prevent damage to the racon as you apply excessive inlet pressure to the purge manifold.

4. Using the vent valve tool (P.N. 297.1010-00), loosen the plug on the purge outlet (at the top of the radome) until you can hear the hiss of escaping gas.

5. Allow the gas to flow into the racon at a minimal rate and to vent from the purge outlet for 5 minutes. The purge gas volume is 10.1 liters for the X+S-band GMU model.

6. Close the purge outlet and secure it with the vent valve tool.



45

Figure 3.1 Racon Purging Operation



46

3.4.3 Repressuring

1. Increase the outlet pressure of the reducing valve to 35 kPa (5 psig). Allow the racon to pressurize until the manifold pressure gauge indicates 3 + 5 kPa (5 + 1 psig). Close the manifold isolation valve and check the pressure on the manifold gauge. If the pressure is too low, open the isolation valve and allow gas to flow for 1 minute. Then close the isolation valve and check again. Repeat until the pressure on the manifold gauge reads 3 + 5 kPa (5 +1 psig).

2. Close the manifold isolation valve and the gas cylinder valve, and set the pressure reducing valve at the minimum setting. Disconnect the manifold outlet hose from the adaptor on the purge inlet fitting. This connection must be broken quickly to minimize the amount of gas escaping from the racon. Remove the adaptor fitting from the purge fitting. This connection must also be broken rapidly to minimize escaping gas.

3. Disconnect and store the purge kit. Secure the gas cylinder by removing the pressure reducing valve and replacing the protective cap.

CHAPTER 4 MAINTENANCE

4.1 ROUTINE FIELD MAINTENANCE

Field maintenance should include the following:

4.1.1 Field Visual Inspection

A. Closely inspect the racon. Look for chips, dings, loose connections, loose bolts and nuts, excessive metal loss, damaged cables and cracks. Racons that have cracked radomes, even ones with very tiny cracks, must be replaced immediately.

B. Is the racon still mounted vertically? A Tideland Signal racon was designed for installation on sea-going buoys; it need not be perfectly vertical. However, racons that are not vertical within five or so degrees may experience a compromised operational range. The antennas are designed to have a vertical beam divergence of approximately 22° from the horizontal. This is stated at ±3dBc or at the half power point; i.e., half of the power received and transmitted is lost when the racon tilts 22°.

C. Look for battery damage such as leaks, cracks, corrosion, and contamination. D. Look for changes in the vicinity. Changes in local structures can affect the coverage area

of a racon. A racon is a line of sight device. Do not let anything come between the racon and the maritime user.

E. Pay lots of attention to the power source. Solar cells should be cleaned, batteries cleaned, cables and connectors cleaned and seated.

F. Check the racon mounting. Look for loose mounting bolts. Make sure that the racon us firmly mounted on a firm foundation. Make sure that there is nothing in close proximity to the racon that could cause damage to the housing, i.e., a swinging rope or line, moving platform, or walkway.

4.1.2 Field Cleaning

A. Clean the outside of the racon with soap-and-water, alcohol, or a product called “Fantastik, All Purpose Cleaner”, made by S.C. Johnson & Son, Inc. If you decide to use the “Fantastik” cleaner, make sure you only use the “All Purpose” product. Excessive surface contamination and build up from bird droppings can reduce the range of the racon. The plastic radome is transparent to microwave energy and is incredibly strong. However, it is susceptible to chemicals such as solvents, gasoline, and common de-greasers. The use of products other than those listed here will cause the plastic to crack at some time in the future allowing the internal gas to leak out and sea water to come in.

NOTE: The electronics within the racon will not survive seawater immersion. Usually after any amount of contamination, they can no longer be repaired

B. Do not attempt to paint the radome. Most paints are not transparent to microwaves and contain chemicals that will permanently damage the racon.



49

C. Chips and scratches of the metal base housing should be attended to immediately. Clean and repair the chips or scratches as soon as you can. Failure to perform this simple maintenance can cause severe damage to the housing with such a loss of metal that it cannot be repaired.

D. Don’t hesitate to paint over scratches in the metal housing. E. Do not let the paint touch the plastic radome.

Tideland Signal Corporation A- 10111181-00 Rev A 08APR09 AppendixA.doc

SeaBeacon 2 System 6 Racon Power Consumption and Discussion of Programmable Features Available to Alter Power Consumption

All racons vary in daily power consumption due to operating conditions, i.e., number of ships, short or long-range settings on radars, racon owner settings, etc.

In an effort to assist you with power supply sizing, the following is presented:

Typical Power Consumption for SeaBeacon 2 System 6

(Based on a PRF of 1 kHz and 20 μsec code length)

System 6 Idle 15 mA Typical .015 X (50% of 24) = .18

Listen 150 mA Typical .150 X (50% of 24) = 1.8 Transmit 150 mA Typical 1.98 AH/day

Optimizing System 6 features to get most efficient power usage

As you can see from the figures noted above, the System 6 racon uses power efficiently. However, you will see that in the figures below, any racon that is interrogated with multiple radars operating on long range, the corresponding long (60+ μsec) racon code length response significantly increases the power consumption.

**Listen current was 130mA and idle current was 12mA. Extended idle mode was turned off.

With the above information it is easy to see that by limiting the maximum code length (an adjustable feature on all SeaBeacon 2s) in a busy location, the daily power consumption can be drastically reduced.

In busy locations, normally the short and medium range traffic are the ones who need the racon paint trace the most. A shorter code length has two obvious advantages. First the paint obscures fewer desirable targets because the paint is smaller. Second, as you can see above, the power



consumption is reduced. The disadvantage is that when the radar is set at its maximum range the Morse character can be so small as to be difficult to read on the screen.

Published power consumption is based on values obtained with two controlled parameters, the PRF set at 1 kHz and the code length set at 20 μsec. Only one band is active during this test. Since the X+S band racon receives radar pulses that are interleaved, the SeaBeacon 2 System 6Racon handles the response on the same basis. The racon can be thought of as a serial device that handles radar pulse one at a time. Therefore, the power consumption of X and S band is not additive.

From the table at 1 kHz and 20 μsec code length, we can see that the listen of 130mA and transmit of 140mA and 143mA are close enough to the same value that the difference between transmit and listen is negligible. Using the worst case of 143mA and adding 5% safety = 150mA X 12 hours (@50% duty) = 1.8 AH/day.

The SeaBeacon 2 System 6 Racon brochure states 2.12 AH/day as an averaged figure. If the PRF is increased to 3 kHz and the code length is limited to 20 μsec we have .183 A X 12H = 2.2 AH/day. However, if you change both the PRF to 3 kHz and increase the code length to 60 μsec the power consumption increases to 288mA X 12H = 3.46 AH/day.

Based on this example and past experience, we know that for 95 % of the racon locations a power source that will deliver an average of 2 AH/day at 12 volts.

For the roughly 5% of locations that are very busy, and don’t fit the above model, the power available must be increased and/or some of the SeaBeacon 2 System 6 Racons programmable power efficiency features must be used to fit the location. In the most severe cases an increased power source and the setting of the racon’s programmable features may be needed to best fit the racon to the requirements of the location and the maximum power available.

An important tool to this end is the extended idle mode feature that is available on the SeaBeacon 2 System 6 racon. It’s purpose is to limit the racon power consumption during periods when there is no local radar traffic. Multipliers of 1 to 10 may be selected by the operator/owner. This multiplier determines the length of the extended idle time before the racon automatically goes into the listen mode for 4.0 seconds. If radar traffic is present during this 4.0-second listen period, the racon will respond normally for as long as radar signals are being received, i.e., the On/Off cycle times are not altered. If no radar signals are received for a period of at least 4.0 seconds the racon goes into the extended idle for the length of time selected. See the following example:



Racon is programmed for 20 seconds on 20 seconds off duty cycle and the extended idle is activated using a multiplier of 5.

(20 sec on + 20 sec off) X 5 (multiplier) = 200 sec

20 sec 20 sec 4 sec 196 sec 4 sec 196 sec 4 sec with traffic

At the beginning of the 20-second on period the listen mode is turned on and stays on for only 4.0 sec if there is no radar traffic present. The racon will go into the low power idle mode for 196 seconds at the end of which it will pop up for another 4 second look for radar traffic. If radar traffic is detected then the racon will resume its normal 20 second on and 20 second off cycle.

In Summary

The following are programmable power saving features of the SeaBeacon 2 System 6 that can be used to reduce power consumption in addition to providing tailored performance influenced by site requirements:

SeaBeacon® 2, System 6 Ex

Installation

INITIAL INSPECTION Initial inspection of a SeaBeacon 2 System 6 Ex racon:1. Receiving:

When the SeaBeacon 2 System 6 Ex racon arrives, make note of any physical damage to the exterior of the shipping container. Exterior damage may be the only clue to possible interior damage caused by rough handling in shipment.

2. Unpacking:

Unpack the racon carefully without damaging the shipping container. The container has custom designed cavities that conform to the shape of the racon. Save it for future use in shipping the racon.

3. Visual Inspection:

After the unit is unpacked, visually inspect the racon for obvious damage. Check that all associated hardware is accounted for and damage free.

INSTALLATION MATERIALS SUPPLIED Your racon is packaged and shipped in a large box that should be temporarily retained for possible warranty returns. All materials required for normal installation are included in the shipping container. The shipping container has within it the racon, a control box, an installation manual and a bag of mounting hardware. Note: Do not discard the installation manual. The manual contains operating instructions that will be needed after the racon is installed.

Locating the Racon

SiteThe racon should be leveled. For fixed mounting surfaces, install the racon within a few degrees of true vertical. For best results, locate the racon as high as practical in order to provide a clear line-of-sight path between the racon and where the client ships or vessels are or will be located. In general, the higher the racon is mounted; the better is its useful range.

For example, a ship’s radar antenna is 15 meters (50 ft) above water, and the highest point of land the vessel is approaching is 91 meters (300 ft) resulting in a nominal radar range of approximately 28 nautical miles.



� �TRTXNM HHR �� 08.2 R is in Nautical Miles

HTX and HTR are Heights in Meters

For more information about racon range estimates, please see the latest IALA publication “Guidelines on Racon Range Performance”.

OrientationThe racon must be mounted vertically. The orientation arrows on the lift ring (opposite the connectors) should point seaward or toward the longest range of the traffic service area.

Interference The racon must be installed in an area that has a clear view or sight of where the client ships or vessels are located. Do not install the racon behind poles, posts, fences or guard rails. The racon signal behaves like light and cannot go through or around objects of any kind.

Racon Mounting The racon can be mounted on a level surface with four hole mounting or on a tilted surface with 3 hole mounting. The racon has a wide vertical divergence of 22º and is well tolerant of slight out of vertical installations. However, maximum range can only be achieved with height, see “Site” above, and a near vertical installation. Locate the TSC 9011042-00 KIT, LEVELING MOUNTING HARDWARE or bag of mounting hardware.

Control Box Mounting The control box, 6301343-00, may only be mounted in a controlled environment. It must not be mounted in a hazardous location where flammable gases or liquids are present or may be present in the future. It must not be mounted in the open weather. Protect the key from loss and misuse. The racon cannot be turned on without the key. Wiring connections are made to Weidm�eller part number 0294360000 feed through terminals. Please see the manufacture’s data sheets for connection details and wire sizes. Connections to the racon junction box are made via Pepperl+Fuchs DP-LBF-11.34 surge protection devices. The maximum wire sizes are 2.5 mm2 or less than 10AWG. See drawing 0701009-DWG included with your racon. All “Customer Field Wiring” should be as short as is practicable.

Power Source Your racon is a 24 volt Direct Current (DC) device. The best power source is a battery with some kind of charger. Electrical DC power supplies may be used but they must be able to go

CAUTIONThe Ground Strap must securely connect to an

earth ground for lightning protection.



from a few milliamps to 2 amperes in less than a few milliseconds. I.e. the power supply must have very low internal impedance. Usually the simplest and most reliable solution is a battery. The DC source should be located close to the control box and the wiring from the control box to the racon should be kept very short. Wire List: Control Box Description Racon J Box 1 Earth 1 2A 24V Battery Minus (-) M1-1 3A 24V Battery Plus (+) M1-2 4 Inhibit or Blanking (+) M2-1 5 Inhibit or Blanking (-) M2-2 6 Go/No Go or Status (+) M3-1 7 Go/No Go or Status (-) M3-2 8 RS232C Rx data M4-1 9 RS232C Tx data M4-2 10 Green Indicator Light M5-1 11 Yellow Indicator Light M5-2 12 Red Indicator Light M6-1 13 Reset M6-2

Initial Turn On of Your Racon When power is initially applied to the control box, the red LED indicator light will come on. In this initial condition there is no power to the racon.

1. Insert, rotate the key clockwise and push in briefly. This action sends a reset or temporary power to the racon.

a. If the internal pressure is greater than 2 PSI (14 kPa) but less than 5 PSI (35 kPa) then the yellow LED light will come on and stay on.

b. If the internal pressure of the racon is greater than 5 PSI (35 kPa) then the green LED light will come on.

c. If either of the yellow or the green lights are on then the racon will function normally.

Note: The yellow light is a warning that the racon is leaking pressure and may soon fail.

d. If the red LED light stays on then the internal pressure of the racon is less than 2 PSI (14 kPa) or there is a wiring error or other failure and the racon will not be allowed to be powered up.

2. If the green light is on then the racon is on and the protection circuits are working. 3. Test your racon with local radars for Morse Code, Time ON and Time OFF, range and

area availability.



INHIBIT AND STATUS DISPLAY

Inhibiting Racon Response to Fixed Radar

Racon responses may interfere with fixed local radars that are on the platform. Inhibiting can be used to eliminate an undesirable racon reply. To use this function connect an inhibit control signal from the fixed local radar to the racon. The inhibit signal should have the characteristics shown in Figure B.1.

Figure B.1 Inhibit Pulse Characteristics

The inhibit signal is driven from an external source of +5V to +12V pulses from a local radar. These signals are to be connected to the INHIBIT (+) with a return connected to INHIBIT (-). The pulses should go active about one microsecond before the radar begins transmission and remain till about one microsecond after the transmission has ended. The input to the inhibit circuit is a NEC PS8701. The NEC PS8701 is an optically coupled isolator containing a GaAIAs LED on the light emitting diode (input) side and a PIN photodiode and a high speed amplifier transistor on the output side. Typical ratings are VF = 1.7V at IF = 16mA (max), VF = 1.6V at IF = 1mA for the LED. The LED has 520 ohms of external resistance in the anode circuit and 50 ohms in the cathode circuit for a total of 570 ohms of series resistance added see Figure B.2.

Figure B.2 Functionally Equivalent Blanking Circuit Inside Racon



Status Display

The status display lines (GO/NO GO + and -) provide a means of continuously monitoring whether or not the racon has passed its self test. Figure B.3 shows a functionally equivalent circuit along with a possible method for implementing the GO/NO GO function. The circuit can switch an outside current source of 125 mA or less. The polarity or signal sense that the SeaBeacon 2 System 6 EX racon provides, is user selectable. The opto-isolator is normally turned on only if there is a racon malfunction. The output of the GO/NO GO circuit is a NEC PS2702-1 optically coupled isolator containing a GaAs light emitting diode and an NPN silicon darlington-connected phototransistor. There are two 50 ohm resistors, one on the GO/NO GO (+) and the other on the GO/NO GO (-), and a 1N4148W diode in series on the GO/NO GO (+) see Figure B.3.

Figure B.3 The GO/NO GO Circuit

Purge and Pressure, General Your racon was factory pressured and purged to 15 PSI (106 kPa) with dry nitrogen. Nitrogen is used to reduce the aging effects of corrosion and oxidation. While nitrogen is recommended it is not required to pressure your racon. Dry air will work for the task; but it must be dry. Any moisture in the air will eventually condense out onto the internal electronics and will significantly shorten the useful life of the racon. The purposes of the pressure are two fold:

1. First, pressuring is necessary to meet the permit requirements of this hazardous area certified product.

2. Second, the internal pressure is an indicator of how well, or not, the racon is sealed against the external marine and potentially explosive environment. The internal electronics are extremely fragile and they are easily damaged beyond reasonable repair efforts by moisture or by chemical contamination.



Routine pressuring or purging is not required nor is it recommended. Routine checks of the pressure are recommended at six month intervals and not longer than one year. The pressure may be tested with an external low pressure gauge or by communications with the racons’ internal pressure sensor. (See section 3.3.3 “User Functions” subsection “7 RACON MONITOR”) Some loss of pressure can be expected over long periods of time. Pressure losses that cause the yellow LED light to come on should be promptly attended to.

Gather and Assemble Purge and Pressure Devices

Parts1. Pressured Nitrogen source – usually a high pressure bottle 2. Low pressure regulator – Pressures in excess of 30 PSI (207 kPa) will cause damage to

your racon that will require extensive and costly repairs. 3. Pressure gauge - capable of displaying low pressures of 1PSI(7 kPa) to 15PSI (103 kPa) 4. Interconnecting hose and adapters

Tideland signal can provide a Purge kit, “9011058-00 KIT, PURGE RACON SEABEACON 2”, to help you in this process. See the drawing 520.1288-CTL on page B-17 in this section. Assemble the parts as shown on the drawing.

Purging and Pressuring

Purge1. Close the isolation valve. 2. Set the outlet pressure of the low pressure regulator to 20 to 25 PSI (138 to 172 kPa) 3. Remove the cap from the purge inlet valve. Set it aside for later. Install adapters as

needed. 4. Remove the tamper resistant vent valve at the top of the racon radome. The vent tool,

2971010-00, or other appropriately sized rod will do. Save the flat gasket. 5. Connect the pressure source hose to the racon. 6. Slowly open the isolation valve. Do not let the pressure climb above 15 PSI (106 kPa). 7. Let the gas flow through the racon and out the top valve for about 5 minutes. 8. Close the isolation valve. 9. Install the vent valve gasket and the vent valve. Tighten the valve with the vent tool until

the valve seats firmly on the radome. Excessive torque will damage the radome bolt, 2111550-00 SCREW CONT RETAINING SBCN-2.

Pressuring1. Slowly open the pressure isolation valve till the gauge reads 15 PSI (106kPa). 2. When the gauge reaches 15 PSI then close the isolation valve. The gauge reading will

drop. 3. Open the isolation valve again till 15 PSI is reached. Close the valve again. 4. Repeatedly open and close the isolation valve until the gauge reading holds at 15 PSI

(106 kPa).



5. Close the isolation valve. 6. Turn off the gas to the low pressure regulator. 7. Quickly remove the hose from the racon purge inlet valve. 8. Firmly reinstall the purge inlet valve cap. 9. Your racon is now purged and pressured. 10. Test for leaks. This can be done with soapy water applied around all connections. If

bubbles are seen then the racon seals must be repaired. Please contact your Tideland Signal Corp. representative for assistance.
