Dangerous electrical voltage!
May lead to electrical shock and burn.
Before beginning of work switch unit and equipment free of 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! Connecting the temperature sensors
The temperature sensors are connected to the clamps 1T1, 1T2, 1T3 and so on. These
pluggable terminals have a special contact material and may only be used for the connection
of the sensors.
When connecting 2 thermocouples they must be isolated from each other.
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
Attention!
When all relays are programmed in operation current mode
(= pick up at alarm), a loss of the supply voltage or an instrument failure
can remain unidentified.
!
When the relay is applied as control instrument, the operator must ensure,
that this error is recognized by regular examinations.
We recommend to program and accordingly evaluate at least one relay
in the closed-circuit current mode.

Parmeterizing the sensors (S 1 / S 2):
Dependent on the chosen program: temperature (Pr 1-5, 9) or current/voltage (Pr 6-8)
Choose menu item with up/down until in indication S 1 and type of sensor alternate.
Here it can be read clearly, which type of sensor is selected and on which alarm the sensor
works (corresponding LEDs alarm on).
Enter with Set in parameterizing sensor e.g. S 1 / 100 for Pt 100.
Choose sensor type with up/down
Set cable resistance or 3-wire configuration (3-L).
2-wire configuration, cable resistance compensation:
Short-circuit the wires nearby the sensor and measure the cable resistance. Set
parameter „LA“ on this value.
With 2-wire connection and a common wire for all sensors, all sensor measuring currents
will be added on the common wire. The compensation value LA to be set is calculated as
follows:
LA = 3 x RL/2 (RL = resistance of two wires)
We recommend 3-wire connection for each sensor.
Parameterizing of the alarms (AL 1 / AL 2):
Choose menu item with up/down until AL 1 and limit (limit value) alternate in display, e.g.
AL 1 und 130 for 130 °C.
Here it can be read clearly, which limit value is parameterized and to which sensor works
on the alarm (yellow LEDs sensor on).
Begin to parameterize with Set.
Adjust limit with up/down. Adjust hysteresis. Negative hysteresis = MAX-switching point, the
relay switches when the adjusted limit is reached and switches back when the signal is
fallen by the hysteresis. E.g. limit 130 °C and hysteresis -5 °C: Relais switches at 130 °C
and switches back at 125 °C. Positive hysteresis vice versa = MIN-switching point.
Alarm delay time dAL: An alarm is suppressed for the adjusted time, short-timed exceeding
of the limit does not cause an alarm.
Switch-back delay doF: An alarm is only switched off after the signal is below the limit and
after delay of this time, e.g. a cooling ventilator can cool further on for this time to avoid,
that it has to switch be switched on again after a short time.
Function of relay:
rrrr-Closed-current circuit mode, relay is picked up in GOOD-state (=limit not reached) and
releases when the limit is exceeded. Advantage: errors and faults normally cause an
alarm. Disadvantage: alarm also when supply-voltage is switched off and after
switching on until the relay has picked up. Unfavourable e.g. with transformers,
particularly, when the supply-voltage of the TR 210 comes from the monitored
transformer.
AAAA-Operating-current mode: relay is released in GOOD state and picks up when the limit is
exceeded. No alarm at errors and when supply-voltage switched off. Used normally
switch ventilators or heatings or for tripping of transformers.
rrrr----L / A
L / A----LLLL: alarm switches locked. Set back with reset only after fall short of the limit (with
L / AL / A
hysteresis) and end of the switch-back delay. Ready for Reset is indicated with „A12LLLL“
in the display mode.
Error report: With Err it can be selected, if the relay switches in the alarm state in case of
sensor-error Er1-9 (short circuit or break). (on / oFF)

Page 7 of 24 Type: TR 210
Test relay (tSt):
Here it can be programmed, that a relay switches into the alarm state after a certain time
don, e.g. 1 weeks (= 168 hours) for the time doF, e.g. 10 s, to make a ventilator or a pump
run for a short time, to make them move and protect the bearings from damage through
long standstill.
Choice of the alarm with up/down. Set switches to don and doF.
don = oFF = test not active.
Sensor simulation (Si):
A sensor can be selected, and a measured temperature can be simulated with the buttons
up/down. All functions of the unit work as if this temperature was really measured. If there
is no button pushed for 15 minutes, the device automatically switches back into the display
mode.
CodE:
After setting all parameters they can be protected by activating the code lock. After pushing
Set, the display indicates Pin. Adjust with buttons up/down Pin504 (factory setting). After
pushing Set, code lock can be activated or switched off. After pushing Set again, an
individual Pin can be selected (write down).
When code lock is activated all parameters can be seen but not be changed anymore.
In case of problems with the code lock (forgotten Pin) the lock can be switched off and the
Pin can be set back to 504, by pushing button set while connecting the device to supplyvoltage until Code / ofF is indicated in the display.
Tips:
- With the pre-set programs Pr1 to Pr9 the most important parameters can be set in
advance, so that only little modifications are necessary, e.g. setting of the limits (limit
values) for each alarm.
- After finishing one menu item it is switched automatically on the next one. E.g. after
programming the line resistance of sensor 1 and pushing Set, the devices switches on to
sensor 2.
- When the right decimal point in the 7 segment display is on, the display mode has been
left, and the menu items can be chosen with up/down (menu mode).
- When the right decimal point blinks, you are in the parameter setting mode and can change
the setting with up/down.
- Long pushing on up/down speeds up the changes in the display.
- Pushing button up and down at the same time sets values to zero.
- With reset (press set/reset for 2s) the display mode can be reached from every position
(exception: simulation) of the parameter setting mode (the last selected value in is being
stored).

Reaction time of the unit – measuring time t M
The reaction time of the unit depends on the number of the connected sensors and the
measuring function. If the temperature is changing constantly, the measuring time t M is
about 2 s. If the temperature is changing rapidly, e.g. through simulation of the temperature
with an external potentiometer, the measuring time t M is about 4 … 6 s. In case of sensor
error the measuring time t M raises to 7…10 s.
