Pt 100 Thermostat TR 600 with interface RS 485
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. Temperatures and switching states of alarms/relays are available at
the interface RS 485. Programming is very variable and simple.
Application
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

Remarks
•LED’s Alarm
off: temperature below switching point
on: temperature beyond switching point
blinking 1x on 4x off: alarm-relay delay time tALARM is running
blinking 4x on 1x off: alarm-relay delay time tALARM off is running
blinking 1x on 1x off: relay locked, ready for reset
Alarm-relay can be resetted 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 M
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 Mis about 1,5 s. With abrupt change of temperature the measuring time t Mis
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 Mincreases 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 tALARM 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. Settings see mode 6.
We recommend using 2 or bettering 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.

Installation - Putting into operation
Attention! Do not plug in or remove terminals with device alive
When installing the device into a cabinet, please observe the max.
admissible temperature. Care for both, sufficient clearance to other devices
or sources of heat or enough forced draught.
Before switching on make sure that the operational voltage Us of the type-
plate and the mains voltage are the same.
Mounting and connection:
•mount on 35 mm mounting rail according to DIN 50 022
•wall-mount with 3 x screws M4 (option)
•connecting wires refer to the wiring diagram to prevent miss-operation and
malfunction.
•apply mains voltage to terminals A1 and A2 (DC A1=+, A2=-, also connect PE)
ATTENTION!
Connecting 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 TR 600 universal power supply works within the ranges AC/DC 24-60V 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.

Trouble-shooting and remedies
•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.
•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 set-up 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 set-up 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 set-up 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 set-up mode 5.
In case of any other malfunctions, replace device and send it in together with a
description of the occurred malfunction.
