HANDLING OF ELECTRONIC EQUIPMENT

A person's normal movements can easily generate electrostatic potentials of several thousand volts.Discharge of these voltages into semiconductor devices when handling electronic circuits can cause

serious damage, which often may not be immediately apparent but the reliability of the circuit will have

been reduced.

The electronic circuits of ALSTOM T&D Protection & Control Ltd products are completely safe from

electrostatic discharge when housed in the case. Do not expose them to the risk of damage by

withdrawing modules unnecessarily.

Each module incorporates the highest practicable protection for its semiconductor devices. However, if it

becomes necessary to withdraw a module, the following precautions should be taken to preserve the high

reliability and long life for which the equipment has been designed and manufactured.

1. Before removing a module, ensure that you are at the same electrostatic potential as the equipment

by touching the case.

2. Handle the module by its front-plate, frame, or edges of the printed circuit board.

Avoid touching the electronic components, printed circuit track or connectors.

3. Do not pass the module to any person without first ensuring that you are both at the same

electrostatic potential. Shaking hands achieves equipotential.

4. Place the module on an antistatic surface, or on a conducting surface which is at the same

potential as yourself.

5. Store or transport the module in a conductive bag.

More information on safe working procedures for all electronic equipment can be found in BS5783 and

IEC 60147-0F.

If you are making measurements on the internal electronic circuitry of an equipment in service, it is

preferable that you are earthed to the case with a conductive wrist strap.Wrist straps should have a resistance to ground between 500k 10M ohms. If a wrist strap is not

available, you should maintain regular contact with the case to prevent the build up of static.

Instrumentation which may be used for making measurements should be earthed to the case whenever

possible.

ALSTOM T&D Protection & Control Ltd strongly recommends that detailed investigations on the electronic

circuitry, or modification work, should be carried out in a Special Handling Area such as described in

BS5783 or IEC 60147-0F.

Section 3. DESIGN AND MODE OF OPERATION

The following chapter describes the mechanical and electrical design as well as therecorder components.

3.1 Summary

The recorders are designed as panel mounted instruments with a format 144 mm x144 mm.

Installation without interspacing is possible in panels and mosaic systems withsufficient ventilation.

The modern recorders have digital data processing. Measured values are recordedserially in channels and with solid state technology.

As a result of the exclusive use of step motors, the drive system for recording operatescompletely without contacts. This technology permits a wide range of applicationsand high functional reliability.

Fig. 1 and Fig. 2 show views of the recorder. The mode of operation of the recordersis explained down to the block diagram level using Fig. 3.

3.2 Recorder components

3.2.1 Housing

The housing is made of sheet-steel. The chassis and the chart carriage are present at

the front; the measuring module, the central processing unit, parts of the powersupply and the options are located at the rear. The housing is mounted in the panel,mosaic system or desk upright panel using the supplied, standardized mountingelements.

3.2.2 Measuring module

The measuring module has up to three channels, a multiplexer with semiconductorrelays and an analog-to-digital converter. The input ranges are set specifically foreach channel using jumpers. The channels are electrically isolated from one anotherby staggered control of the semiconductor relays.

Control is handled by the central processing unit. All channels to be measured during

a cycle are connected to the input amplifier in succession via the individual

7/27/2019 I9-089B R30 R40

18/124

Page 18

semiconductor relays. The amplified signal is applied to an analog-to-digitalconverter which operates according to the dual-slope procedure.

In order to permit equally accurate measurements in sensitive ranges, referencemeasurements are carried out cyclically in the recorder version with universalmeasuring ranges. A cyclic check is also carried out for open-circuits.

The terminal block also contains a sensor for measuring the terminal temperaturewhen carrying out temperature measurements using thermocouples.

3.2.3 Central processing unit

The central processing unit is the heart of the electronics. It contains a microprocessoras well as the program memory (EPROM), main memory (RAM) and non-volatilememory (EEPROM) for configuration data.

Central component of the processing section is a microprocessor system withfirmware. This is used, inter alia, for:

q Sequence control

q Calculation of measured values

q Positioning of pen assemblies

q Evaluation of input commands

q Use of PC interface.

The central processing unit permits control of the module Digital input/ output.

A crystal-controlled calendar/ clock with external synchronization facility provides thedate and time as a reference for sets of measured values and the chart.

The central processing unit is located at the rear of the housing and is accessiblefrom the front following removal of the chassis. It contains the plugs for connection of

the other modules.

3.2.4 Power supply

The recorders have different designs on the input side as a result of the four differentpower supplies which can be ordered.

3.2.4.1 AC 230V orAC 115V

The mains power supply is connected to the recorder via an appliance plug withsubsequent fuses, filter and transformer. The stepped down ac voltage is rectified,filtered and applied to dc/ dc converters which generate the required internal dcvoltages.

Note: The recorder must only be connected to the envisaged power supply.Observe the corresponding note on the rear of the recorder.

3.2.4.2 DC 24V

The dc 24V supply connected via the terminals is applied via a fuse to a powerinverter whose output is connected to a transformer. The secondary side of thetransformer is connected as in the recorder version with a mains power supply.

3.2.4.3 AC 24V

The ac 24V supply connected via the terminals is applied via a fuse to the primaryside of the transformer. The secondary side is connected as in the recorder versionwith a mains power supply.

3.2.5 Chassis

The chassis contains the chassis support, control PCB, recording system, userinterface, PC interface and chart carriage. The chassis is connected to the centralprocessing unit via a multi-conductor ribbon cable with plug. The cable length is suchthat the chassis can be completely removed from the housing without loosening the

connection.3.2.5.1 Chassis support

This is the support for the motors of the recording system, the control PCB, userinterface and PC interface. The chart carriage latches into the chassis support andcan be removed at any time using lever 2, eg. to replace the chart.

3.2.5.2 Control PCB

The control PCB contains the power electronics for the step motors of the drives aswell as the light barrier for detection of the carriage zero points. It also contains amicroswitch for recognizing the end of the chart paper, and several microswitcheswhich are activated using the levers.

3.2.5.3 Clock backup

Only R40 version: the clock backup consists of a backup battery and capacitor. If abattery is not present, or if the chassis is separated from the central processing unit,the capacitor buffers the internal clock for approx. 5 minutes. The status of the clockbuffer is checked when the power supply is switched on.

The support for the backup battery is present on the control PCB and accessiblefollowing removal of the chassis.

3.2.5.4 Recording system

The recording system consists of up to seven step motors depending on the recorder

version. These are used for:q Chart drive

q Positioning of the three coloured pens in the xdirection

q Pen lift

q R40 version: positioning of pen for text channel in x and ydirections

3.2.5.5 Chart carriage

The chart carriage permits fanfold packs or rolls to be used as the chart paper.A take-up spool is required when using rolls. In addition, the chart carriage must beadapted when changing from fanfold paper to rolls. The required operations are

described in Section 7 Servicing and Maintenance.

3.2.5.6 User interface

The user interface consists of four levers and two LEDs underneath the chart carriage.A further lever is present on the side of the chassis and is only visible when thechassis is in maintenance position.

Mechanical operations are directly activated by two of the four levers underneath thechart carriage. The other two levers can be used for two different actions each bymoving the respective lever to the left or right. The TEST menu can be activated andswitched off again using the switch which is accessible on the side of the chassis.

Green and red LEDs indicate different recorder statuses depending on how they areactivated (on, off, flashing).

3.3 Mode of operation

As a result of the many different possible uses, the recorders are delivered preset tothe basic setting of 4 to 20mA.

Customer-specific presetting is also possible as required. The recorder can then beused immediately following installation and commissioning.

The values measured cyclically by the recorder are amplified, digitized andprocessed further by a microprocessor system.

In addition to processing of the measured values, the microprocessor system isresponsible for sequence control, self-test, event processing, control of the step motorsof the recording system, feedbacks from the recording system and the user interface.

The microprocessor system converts the measured value into positioning commandsfor the recording system. The pens draw a continuous line on the chart paperaccording to the measured signal. You can adjust the measuring and recordingranges such that the signal is recorded with an optimum resolution and display.It is also possible to define limits which are constantly recorded in the R40 version as

vertical lines. The recorders can output an alarm text if the limit is violated.The number of limits and the alarm function can be parameterized within wideranges. If the recorder is equipped with the digital input/ output option, the alarmscan be output for further processing.

The R40 version can output a measured-value table, event text and recorder textcyclically or event-controlled. The texts must be entered previously via the user whensetting up the recorder. The outputs are made depending on the recorder parameters.

4.8 Starting up the recorderAll recorder settings have already being made in the factory if the recorder has beendelivered according to customer specifications.

The standard settings have been made for recorders delivered without customerspecifications. The standard settings are listed in Section 5 Operation in therespective subsections.

If you are not acquainted with the recorder, it is recommended to start with simplemeasurements after working through Sections 2 to 5. Measurements with thestandard settings are most appropriate initially.

Section 5. OPERATION

The following chapter describes how to operate the recorders.

Note Replacing the chart and the battery for backing up the clock are described inSection 7.

You are guided by menus when operating the recorders. The menus provideinformation in the form of a table on the respective functions or values for an input(leaflet Parameterization a concise overview).

The input menus consist of several elements which are comprised in turn of menu

code numbers and designations.

7/27/2019 I9-089B R30 R40

39/124

Page 39

In the first input step (selection of row) you decide which function or parameter is tobe called. The red LED lights up.

In the second step (selection of column) you can define or modify the correspondingsetting of the recorder. The red LED flashes.

The input of a menu code number is terminated by ENTER.

You can scroll through the menu using the INC/ DEC functions.

5.1 Display and control elements

Operation is carried out using four horizontal levers located below the chart carriage(Fig. 29). A further lever is present on the side of the chassis. Two coloured LEDswhich are also located below the chart carriage serve to support you when setting upthe recorders and for the output of status messages. In the R40 version statusmessages are additionally printed on the chart paper by means of the text channel(Section 6).

5.2 Display elements

The recorders are equipped with two colored LEDs whose combined statuses (on, off,flashing, fast flashing) indicate status messages. Table 4 lists a summary of the statusmessages assigned to the LED statuses.

Table 4 Summary of LED status messages

5.3 Levers

The levers have different effects. The black service lever and lever 2 act directly onthe mechanics. The other levers act on microswitches whose signals are processed bythe central processing unit. The levers are used for recording, START, STOP or PAUSEOFF, PAUSE ON, high chart speed and recorder settings via the PROG and TESTmenus.

7/27/2019 I9-089B R30 R40

41/124

Page 41

Feedbacks for the user when setting up the recorders are via the LEDs and thepositions of the pens. The rows and columns of the PROG and TEST menus designedin tabular form directly correspond to the value of the parameterization scale, ie. ascale value of 15% corresponds to row 15 or column 15 depending on the status ofthe red LED.

The levers are assigned different functions during operation, PAUSE and when settingup the recorder. Fig. 31 shows a summary of the lever functions. These functions aredescribed in detail in the following sections.

Fig. 31 Summary of lever functions

5.3.1 Functions of service lever and lever 2

5.3.1.1 Service lever Releasing the chassis

The service lever is used to release the chassis. The chassis must be moved to themaintenance position in order to change the pens or scales. To do this, briefly movethe service lever to the left, and simultaneously pull out the chassis until this latches inthe maintenance position. The chassis must be returned to its original positionfollowing the required operations. To do this, move the service lever to the left again,and simultaneously push in the chassis until it latches in place.

The chassis can be completely removed from the housing in order to replace thebattery for backing up the clock (only R40 version). To do this, release the chassis inthe maintenance position using the service lever, and pull out the chassis to the front.When inserting the chassis again, you must again release it at the maintenanceposition using the service lever.

Section 7 describes the above operations in detail.5.3.1.2 Lever 2 Releasing the chart carriage

Lever 2 is used to release the chart carriage from the chassis. This is necessary inorder eg. to replace the chart.

5.4.1.3 Event-dependent chart speed

The recorder selects chart speed A when switched on. The event sources are alsoprocessed even if recording is switched off. The currently active status is retained ifno conditions are fulfilled for chart feeds A and B or if both conditions are fulfilledsimultaneously. A change is made to chart speed B if the condition set for it is

fulfilled. The same applies to a change from B to A.If the alarm of a channel is used as the condition, if Mode OFF is selected for theassociated channel.

See Section 5.6.1 for setting example.

Fig. 33 Programmable parameter Chart speed

5.4.1.4 Details on selection of chart speed

Switching over commences with a marker in the form of small horizontal lines on the

curves and a fast feed of at least 7mm such that a setting on the main time lines - ifset - is retained. Small horizontal lines are then again drawn on the curves, and therecording commences with the new chart speed. At the same time, the text channel ofthe R40 version starts to write a chart switching line.

Note If the chart speed is switched over too frequently in succession, the recordingsystem would be overloaded and the measured values lost. Therefore therecorder switches over again at the earliest after approx. 30s.

The following example clarifies the mode of operation of chart speeds A and B withcondition.

7/27/2019 I9-089B R30 R40

49/124

Page 49

5.4.1.5 Example

Chart speed A is set to 20mm/ h [P0.30]. The condition is present at Input DI2[P5.70].

Chart speed B is set to 120mm/ h [P10.40]. The condition is at / Input DI2[P15.75].

Result:

The chart speed is 20mm/ h in measuring mode if the signal at input DI2 is High.The chart speed is switched over to 120mm/ h if the signal changes to Low.This status is retained until DI2 changes to High again. The chart speed then returnsto 20mm/ h.

5.4.2 Measured-value table (only R40 version)

5.4.2.1 P[20] Measured-value table

The R40 version prints a measured-value table (Fig. 56 Example recording for R40version as required with the following information, if relevant:

q Date and time

q Channel number

q Measured value

q Dimension

q Symbol for open-circuit

q Status of alarms assigned to the channel.

Printing can be triggered cyclically or event-controlled.

Parameterization is carried out according to Fig. 34.

5.4.2.2 Printing the measured-value table

The graphic recording is not interrupted when printing the measured-value table, ie.the 2nd and 3rd lines are only printed if the chart feed has reached a full line heightsince the last line. If a further trigger function for a measured-value table or an eventtext arrives whilst a table is being printed, this is only commenced when the table hasbeen completely printed and the chart feed has reached a full line height since thelast line.

The printout of the measured-value table always coincides with a time mark if it iscarried out cyclically. The first line of the measured-value table is omitted in this case.

The minimum distance between two cyclic printouts is 10 mm.

The measured values at the printed time are stored in intermediate memory beforebeing output. Only those channels are printed out for which Measuring orRecording has been selected.

See Section 5.6.2. for setting example.

5.4.3.9 P[60] Open-circuit

Only R40 version. Monitoring is carried out for an open-circuit in the mV measuringranges and the TC, RTD, R and Pot. ranges based on them.

As soon as the internal resistance of the sensor exceeds a certain value, therecording is continued on the left of the 0% line in the case of the setting < 0%

(Fig. 41), and on the right of the 100% line in the case of >100%. The R40 versionadditionally outputs the event Open-circuit in the measured-value table (Section5.4.2) printed on the chart paper.

An open-circuit is not detected in the setting OFF.

Fig. 42 Example of display with open-circuit

5.4.3.10P[65] Damping

The damping is determined by the time constant of a 1st order low-pass via which thesignal connected to the input terminals of the recorder is filtered. The output signal ofthe low-pass is an exponential function following a jump in the signal at the input.

The time constant defines how long it takes until the output signal has attained 63.2%of the stationary final value. Set 0s for output of unfiltered measured values.

The damping must be set individually for each channel. With the setting auto, the

damping is automatically adapted to the chart speed. The basic setting is 0s.

5.4.4 Parameterizing the digital channel (only R40 version)

5.4.4.1 P[70] Channel (digital)

The recorder has two digital channels in addition to the three analog channels.An alarm (Section 5.4.5) or a digital input (Section 5.6) can be selected as the

source. The binary signals of the digital inputs are displayed as a square-wave signalat defined chart positions (Table 11):

Channel #1d Channel #2d

Logical 0 (Low) 81% 91%

Logical 1 (High) 89% 99%

Table 11 Chart positions of channels (digital)

The digital channels are recorded by the mechanical system of the text channel.Edges from logical 0 to 1 and logical 1 to 0 as well as peaks are recorded ascontinuous lines. Constant signal sequences are recorded as dashed lines. The linesare spaced at 10 mm with low chart speeds, and at 20mm with high chart speeds(see Fig. 56 Example recording for R40 version).

Fig. 44 shows the possible parameters.

Page 59

Fig. 44 Summary of parameter Channel (digital)

5.4.5 Alarm

The recorder permits the programming of up to six alarms, each of which is assignedto a fixed output of the digital input/ output (option) (Table 3). A set alarm becomesactive in Measure or Recording mode if the set limit is violated.

The assignments of the alarms to the individual channels, mode and alarm value arefreely selectable. The settings always commence with selection of an alarm.


5.4.5.1 P[80] Alarm

The parameter Alarm is used to select one of the available alarms A1 to A6 towhich the mode, channel and value apply in a subsequent setting.

5.4.5.2 P[85] Mode

The parameter Mode can be used to define whether the alarm is to be triggeredwhen MIN is fallen below or MAX exceeded.

With the R40 version, limit lines can be drawn parallel to the time axis. These linesare vertical and approx. 1mm long. The spacing between the individual lines is

reduced by half if the limit is violated. The lines are drawn by the mechanical systemof the text channel. The alarm symbol, the associated alarm number, the channelnumber or the character (with the setting All channels) are written cyclically nextto the limit lines. The limit line can be set for each alarm using the parameter MINwith line or MAX with line.

In the setting Status (only available in recorders with option Digital input/ output),recorder readiness is signalled if all of the following conditions are fulfilled:

q Power supply present

q PROG menu not switched on

q TEST menu not switched on

1) Only R30 version

7/27/2019 I9-089B R30 R40

60/124

Page 60

q Recording started

q Chart paper present

q Last adjustment of recording system fault-free.

Use of the status message is particularly meaningful if the recorder cannot be directly

viewed.A control signal is output in the position Time marker (only available in recorderswith option Digital input/ output) at the start of the zero adjustment. This signal canbe used to synchronise the cyclic zero adjustment of several recorders using this oneas the master.

An alarm is not output in the position OFF. All alarms are switched off in the basicsetting.

5.4.5.3 P[90] Channel

The 6 alarms can be freely assigned to the individual analog channels. The basicsetting is as follows:

q Alarms A1 and A2 to channel 1



A further possibility is the assignment of a common alarm to the channels in thesetting All channels and applies to the channels for which Measure orRecording mode has been selected. The alarm is triggered if the value is exceeded(max) or fallen below (min) for at least one of the channels.

5.4.5.4 P[95] Value

The setting Alarm, Value is used to define the percentage with respect to the

recording range at which the alarm to be triggered. The selectable range of values isidentical to the recording range and can be set in steps approx. 0.1%.

These texts are suppressed in the setting Alphanumeric OFF.Output of the time at the left edge of the chart is suppressed in the setting TimeOFF. The underline character is still output. The date is still printed out every 12h.

The following texts are suppressed with the setting Status line OFF:

q Start line when starting recording

q Chart switching line when changing the chart speed

q Text with PAUSE ON

(see Fig. 56 Example recording for R40 version ).


5.5.2.2 Start line (only R40 version)

The printout of the start line and the graphic recording commence simultaneously, ie.the arrangement of the pens means the start line appears in the chart (see Fig. 56Example recording for R40 version).

The start line consists of the word START, the date, time, active chart speed andmeasuring cycle. The graphic recording commences together with printing of the startline.

An abbreviated start line is printed when the chart speeds A and B are changed.This line consists of the time and the active chart speed.
