1 Application and short description
The Pt 100 thermostat TR400 is a temperature controller and monitors up to 4 Pt 100 sensors at the same
time. 4 switching points and 4 relays permit almost any combination of switching action. It also can select the
highest temperature of a group of 3 or 4 sensors. The temperatures of two sensors or groups of sensors can
be issued to 2 analog outputs i.e. for remote displays or further evaluation. Programming is very variable and
simple.
Due to the fact that 4 type Pt 100 sensors can be connected, the unit is especially suitable for temperature
monitoring wherever up to 4 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

5 Important notes
Danger!
Hazardous voltage. Will cause death or serious injury.
Turn off and lock out all power supplying this device before working on
this device.
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. If, 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.
ATTENTION!
Connecting temperature sensors Pt 100
Temperature sensors must be connected to the plug-in terminals 1T1, 1T2, 1T3 etc.
To ensure proper operation this plug-in terminals have gold-plated contacts. Do not use these plugs for other
terminals.
The measuring-inputs 1T1 to 4T3 and RESET Y1, Y2 do not have an insulation to
USB-Terminal and to analog output OUT 1 / OUT 2.
The temperature-sensors need an appropriate insulation that complies with SELV
(Safety Extra Low Voltage).
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! Universal power supply
The unit is equipped with an universal power supply, that is suitable for DC- and AC voltages.
Before connecting the unit to the current, make sure that the allowed scope of
voltage of the control voltage Us, written on the lateral type plate, corresponds to the supply
voltage of the unit.
Attention!
The sensor-alarm-relay K7 signals an error in a sensor. The relays for the
alarms 1-4 do not switch with a disturbance in a sensor. When relay K7 is
programmed in closed-circuit current mode (= release at alarm = factory setting),
also an interruption of the supply voltage and an instrument failure are reported.
We recommend the evaluation of K7.

•mount on 35 mm mounting rail according to EN 60715
•wall-mount with 3 x screws M4
•connecting wires refer to the wiring diagram to prevent miss-operation and malfunction.
A circuit-breaker or switch must be situated within easy reach of the
unit and fused. Installation excess current protection should be ≤ 10 A.
7 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 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 autoreset function.
•Functions of USB-Stick
With the 2 functions
- „transfer configuration-file from TR400 to USB-Stick“
- „transfer configuration-file from USB-Stick to TR400“
settings of a readily configured TR400 can be easily read-out and transferred to other TR400.
The USB-Stick is necessary for configuration and for firmware-updates only.
It may not stay plugged during normal operation.
Select Mode „A“, then choose function with button „Alarm Select“:
Alarm LED 2 = transfer configuration-file from USB-Stick to TR400
Alarm LED 3 = transfer configuration-file from TR400 to USB-Stick
Alarm LED 4 = update of firmware
Attention: As long as TR400 is reading from or writing on the USB-Stick, all relays are released and no
values are measured
The file system on the USB-Stick has to FAT or FAT32. The files must be located in the main directory
(highest level) of the USB-Stick. Info’s and Download www.ziehl.com.
File for configuration: „TR600.cfg“ / file for firmware-update: „TR600.hex“
On www.ziehl.com / downloads a parameterizing web site is available.
With this help the following activities can be done easily:
- create and change configuration-files
- check downloaded configurations-files
- documentation of configuration-files
You will also find a update instruction and the latest firmware-version there.

•Relay locked active (Mode 4 = "1")
In this mode the relay can switch on when all the following parameters are full filled:
- 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 and 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
At this menu item a sensor (or sensor group) can be selected and with the buttons up/down a measured
temperature can be simulated. All functions of the device act as if the temperature was measured in
real.
If no button is pushed within 15 minutes the relay automatically returns in the normal function mode.

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 unauthorized 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" or “E 2”, 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.
•Indication of the firmware-version: Push „Set“ for 4 s in the display mode.
•USB Stick –Error when writing configuration-file to USB-Stick: The file „TR600.cfg“ is being
created or overwritten. In addition a file „TR600_xx.cfg“ is being created. „xx“ stands for a continuous
index (00 … 99).
•USB Stick –Error when reading configuration-file from USB-Stick: The file „TR600.cfg“ must be in
the main directory. Parameters in this Text-file can be changed (text editor) and adapted to the
required configuration.
