LPD-Series Installation Instructions READ ALL INSTRUCTIONS PRIOR TO SYSTEM INSTALLATION. ALL WIRING IS TO BE DONE IN ACCORDANCE WITH ALL NATIONAL AND LOCAL ELECTRICAL CODES. POWER IS TO BE OFF DURING ANY WIRING. WIRE AND TEST ENTIRE SYSTEM BEFORE UTILIZING SK-3 CONNECTOR SEALING KITS. STANDARD EQUIPMENT IS COMPATIBLE WITH MOST PETROLEUM PRODUCTS. SOME CHEMICAL AND SOLVENTS REQUIRE SPECIFIC MATERIALS OF CONSTRUCTION. IF UNSURE OF COMPATIBLE CONTACT MANUFACTURER. 1. L-SERIES SENSOR

L-1 SENSOR

The L-1 sensor (see pg.8) is primarily used to detect a liquid level inside the tank. The sensor detects a single liquid level and is typically used for overfill protection at 90% tank capacity. Standard sensor part numbers are L-1-S (12”), L-1-L (20”), L-1-D (custom length). The L-1 sensor is installed into the tank via the 2” bushing which is an integral part of the sensor. This sensor screws directly into a 2” female threaded NPT (use a reducer bushing if necessary). Connection of the sensor to the control unit cable is made in a junction box. For detailed wiring scheme refer to appropriate drawing (see pg.6 and 17). These connections must be made using supplied SK-3 connector sealing kit.

PDS SENSOR

The PDS sensor (see pg.7) is designed to detect liquid in sumps or containment areas. To install the PDS sensor as an above ground sump sensor mount a junction box between 2 and 3 feet above bottom of containment area. Attach sensor to junction box via conduit or cable clamp, leaving a ¼” clearance between the sensor end and the bottom of the containment area. For detailed wiring scheme refer to appropriate drawing (see pg.6 and 17). Connect sensor cables to control unit cables in junction box using supplied SK-3 connector sealing kit.

PDW-* SENSOR

PDW-* sensor (see pg.9) is designed to detect liquid and differentiate water from hydrocarbons in the interstitial space of a double wall tank. The PDWF-* sensor is designed for fiberglass tanks and the PDWS sensor is designed for steel tanks. 1. The PDWF-* sensor is installed through the interstitial port. If the tank is

pitched, locate the interstitial sensor at lowest elevation of tank. Insert sensor into the interstitial port and push down around outside of inner tank. When PVC handle contacts the inner tank the sensor should be located at the bottom of interstitial space. Reduce the riser to 3/4" NPT and install the supplied oiltight fitting. The oiltight fitting must be installed to prevent liquids from entering the interstitial space. Run conduit from interstitial man hole to the central junction box, located in the manway. Install a second oiltight on the sensor cable and pull sensor cable through conduit. Connect oiltight to conduit and tighten. For detailed wiring scheme refer to appropriate control drawing (see pg.6 and 17). Connect sensor wires in central junction box to control unit cable(s) and use SK-3 connector sealing kit.

2. To install the PDWS as a doublewall steel tank sensor remove the oiltight

from the sensor cable. Feed the cable through the appropriate bushing required to adapt the interstitial port to 3/4” NPT (oiltight). Feed wires through oiltight, leaving it loose. Gently lower sensor down interstitial port until it rests on the bottom. Install oiltight into the bushing. Pull sensor up by the cable until it just comes off the bottom. Maintain this position and tighten the oiltight fitting. This is required to seal the interstitial port. All connections are made using the supplied SK-3 connector kit

2. CONTROL UNIT The control unit (see pg.1) should be mounted in a manned area. Route sensor control cable through conduit from the junction box to the control unit. Sensor control cables enter the control unit through the output port only. The cables are wired as shown in the appropriate drawing (see pg.6). The control unit accepts any possible combination of L-series sensors.

INPUT POWER HOOKUP

Input power requirements are: 85 – 125 VAC 16 Watts max 47 – 440 Hz Input power cable should be wired in accordance with all pertinent electrical codes. This cable should enter the control unit through the input power port only. The power is hooked up to the power supply and wired as per control drawing (see

page 17). NOTE: EARTH GROUND TERMINAL MUST BE CONNECTED.

REMOTE ANNUNCIATOR OPTION

Mount remote annunciator (see pg.16) within audio / visual range of the filling operator. NOTE: the remote must be outside of the HAZARDOUS AREA. Pull appropriate low voltage wire from the remote to the control unit. See appropriate drawing for wiring details. Run wires through output port. Connect color coded nuts. SK-3 CONNECTOR SEALING KIT

OMNTEC LPD-Series System Operation and Test Instructions

1. On the front panel the Green “SYSTEM DETECTING” light should be on

indicating that system is up and running

2. If sensors are not in alarm, all Red and Amber lights should be off (see figure 1)

Optical sensors are solid state and use a normally closed light loop in a prism

for sensing. When liquid is present at sensor, the normally closed loop

opens, thus sending an alarm signal back to the alarm panel. The panel

responds by turning on the appropriate light and sounding an audible alarm

(see figure 2). The audible alarm will signal for 30 seconds. The visual alarm

will remain on until alarm condition is cleared.

PD-series sensors contain a conductivity electrode that will send an alarm

upon presence of water. In the unlikely event that the conductivity electrode

does not detect water, the sensor will send a liquid alarm signal to the

controller as described in 2a.

3. Sensors can be tested as follows:

Since sensors work with normally closed loop of light be sure sensor is not

exposed to light source of any kind

Hit the test button on alarm panel and observe panel lights (see figure 3)

If all lights illuminate and audible alarm sounds, system test is complete

When test button is hit a signal is sent to sensor to turn its prism light off.

What this does is put the sensor into a true alarm condition

The sensor then responds as explained in part (2)

Pressing Horn OFF button will silence audible alarm

The conductivity portion of the sensor can be tested by submerging the

sensor in water

4. System should be tested on at least a weekly basis

5. Every alarm, malfunction and test result should be recorded in a dated signed log

Note: If a reservoir or high/low sensor is being used follow same procedures as above to test its high level portion. To test low level sensor, it must either be lifted out of liquid, or liquid level must be lowered below sensor
