Application and short description

The Pt 100 thermostat TR 600 is a temperature controller and monitors up to six Pt 100

sensors at the same time. Six switching points and six relays permit almost any combination

of switching action. It also can select the highest temperature of a group of three or six

sensors. The temperatures of two sensors or groups of sensors can be issued to 2 analogue

outputs i.e. for remote displays or further evaluation. Programming is very variable and

simple.

Due to the fact that 6 type Pt 100 sensors can be connected, the unit is especially suitable

for temperature monitoring wherever up to 6 different measuring points must be monitored

simultaneously:

•motors and generators with simultaneous monitoring of bearings and coolant.

•transformers with additional monitoring of the core temperature also.

•power machines and plants

Approval

USL, CNL Industrial Control Equipment 82VN

Overview of functions

•Measuring and monitoring range -199 ... +800 °C

•6 sensor inputs with 2- or 3-wire connection

•7 relay outputs with change-over contact

•Alarm 1 … 6 relay K1 (11/12/14) ... K6 (61/62/64)

•Sensor Error Relay K7 (71/72/74) monitors sensor break or sensor short circuit.

•RS 485 interface

•Universal power supply. 2 ranges AC/DC 24-60V or AC/DC 90-240 V

Important notes

ATTENTION

Dangerous electrical voltage!

May lead to electrical shock and burn.

Before beginning of work switch unit and equipment free of

voltage.

To use the equipment flawless and safe, transport and store properly, install and start

professionally and operate as directed.

Only let persons work with the equipment who are familiar with installation, start and use

and who have appropriate qualification corresponding to their function. They must

observe the contents of the instructions manual, the information which are written on the

equipment and the relevant security instructions for the setting up and the use of

electrical units.

The equipments are built according to DIN / EN and checked and leave the plant

according to security in perfect condition. f, in any case the information in the

instructions manual is not sufficient, please contact our company or the responsible

representative.

Instead of the industrial norms and regulations written in this instructions manual valid

for Europe, you must observe out of their geographical scope the valid and relevant

regulations of the corresponding country.

Observe the maximum temperature permissible when installing in switching

cabinet. Make sure sufficient space to other equipment or heat sources. If the

cooling becomes more difficult e.g. through close proximity of apparatus with

elevated surface temperature or hindrance of the cooling air, the tolerable

environmental temperature is diminishing.

ATTENTION!

Connect temperature sensors Pt 100

Temperature sensors must be connected to the plug-in terminals T11, T12, T13 etc.

To ensure proper operation this plug-in terminals have gold-plated contacts. Do not use

these plugs for other terminals.

Universal power supply

The universal power supply works within the ranges AC/DC 24-60 V or AC/DC 90-240 V.

Before switching on make sure, that the operational voltage Us of the type- plate and the

mains voltage are the same.

Attention:

Sensor-Inputs and Interface RS 485 are the same potential. Please regard.

RS 485 interface:

Large cable lengths may shift the potential ground and the transmission can be disturbed.

Corrective measures can be galvanic separation or an additional ground wire.

Attention!

The sensor-alarm-relay K7 signals an error in a sensor. The relays for the

alarms 1-6 do not switch with a disturbance in a sensor. When relay K7 is

programmed in closed-circuit current mode (= release at alarm = factory settings),

also an interruption of the supply voltage and an instrument failure are reported.

We recommend the evaluation of K7.

Assembly:

•on 35 mm mounting rail according to EN 60715

•wall-mounting with 3 x screws M4

•to prevent miss-operation and malfunction connect wires refer to the connection plan.

Putting into operation

Remarks

•LEDs Alarm

off: temperature below switching point

on: temperature beyond switching point

blinking 1x on 4x off: alarm-relay delay time t

ALARM

is running

blinking 4x on 1x off: alarm-relay delay time t

ALARM

off is running

blinking 1x on 1x off: relay locked, ready for reset

Alarm-relay can be reseted with reset-push-button or external contact closed Y1, Y2. A

closed contact or short circuit at terminals Y1-Y2 means no auto reset function.

•Operating delay time – measuring time t

The operating delay time of the relay depends on the number of connected sensors and

the measuring function. With continuous change of temperature the measuring time t

about 1,5 s. With abrupt change of temperature the measuring time t

is about 3 … 4 s

(for example by simulation of temperature changes in mode 8). With sensor short circuit or

sensor interruption the measuring time t

increases to 6…8 s.

•Relay locked active (Mode 4 = "1")

In this mode the relay can switch on when all the following parameters are fulfilled:

- the temperature decreases below the switching back limit

- the alarm relay delay-time t

ALARM

off has overrun

- a reset signal Y1,Y2 (reset push-button or external closed contact) is done or the mains

(supply voltage) is switched off an on.

In the ready for reset status the alarm-LED will be blinking 1x on 1x off .

•2-wire technique line resistance compensation

To compensate the line resistance short-circuit the wires nearby the sensor and measure

the line resistance. Setting see mode 6.

We recommend to use 2 or better 3 wires for each sensor. With 2-wire connection and a

common line for all signals, all sensor measuring currents will be added on the common

line. Thus the value of the compensation line resistance RK must be calculated as

follows: RK = (n+1) x RL/2 (RL = line resistance of two wires, n = number of sensors)

•Sensor simulation

If no button is pushed within 15 minutes the relay automatically returns in the normal

function mode.

Trouble shooting

•LED sensor error

The LED sensor error indicates a failure at a sensor and the sensor-LED blinks. The

sensor alarm relay K7 has switched. Refer to operation mode 5. Also see analogue

output.

•Display

EEE sensor interruption or over-range

-EE sensor short circuit or under -range

•Reset to factory adjust

When pushing the buttons "Reset" and "Set" simultaneously > 5 s all programmed

parameters will be set back to factory adjust. Code save must be off. If code save is on,

see mode 9.

•No parameter setup possible - code save on

Code save protects the relay against not allowed manipulations. With code save on no

programmed parameters can be changed. The factory code is 504 and cannot be

changed by the user. See setup mode 9.

•Failure display "E 0", sensor error relay K7 switching

Operation failure. Switch off the supply voltage and restart. When the failure is still going

on, the relay should be replaced and send to the factory.

•Failure display "E 1" or "E 2", sensor error relay K7 switching

EEPROM parameter failure. Check all programmed parameters and setup new when

necessary. Switch off the supply voltage and restart again. When the failure is still going

on, the relay should be replaced and send to the factory.

•Sensor alarm relay K7

Sensor alarm relay K7 with operating function 2 = NC-contact releases at any failure and

signals an interruption of power-supply.

ATTENTION! . There is a short alarm-signal of K7 when switching-on the supply-voltage.

Sensor alarm relay K7 with operating function 1 = NO-contact picks up at any failure.

ATTENTION: There is no alarm-signal of K7 if interruption of power supply occurs.

See setup mode 5.

In case of any other malfunctions, replace device and send it in together with a description

of the occurred malfunction.

•Indication of the software version: Push „Set“ 4 s in the display mode.
