2. Introduction
The GIR 230 TC is a universal, microprocessor controlled displaying -, monitoring- and controlling device.
The device is supporting one interface for the connection of:
- Thermocouple probes type K, J, N, T and S
- Standard signals 0-50mV
The device features three switching outputs (2 * Relays, 1 * NPN-Output),
which can be configured as 2-point-controller, 3-point-controller, 2-point-
controller with min./max. alarm, 3-point-controller with min./max. alarm, or
just individual min./max. alarm.
The state of the relay outputs is displayed by two LED’s beneath the front 4-digit LED-display. The left LED
displays the state of the 1st relay, the right LED displays the state of the 2nd relay.
When leaving factory the GIR230TC has been subjected to various inspection tests and is completely cali-
brated.
Before the GIR230TC can be used, it has to be configured for the customer’s applica-
tion.
Hint: In order to avoid undefined input states and unwanted or wrong switching processes, we
suggest to connect the device’s switching outputs after You have configured the device
properly.
3. Electrical connection
Wiring and commissioning of the device must be carried out by skilled personnel only.
In case of wrong wiring the GIR230TC may be destroyed. We can not assume any warranty in case of
wrong wiring of the device.

3.3. Connecting an input signal
Please take care not to exceed the limitations of the inputs when connecting the device as this may lead
to destruction of the device.
3.3.1. Connecting a thermocouple probe or 0-50mV transmitter
Thermocouple probe 0-50mV - transmitter (3-wire-technology)
3.4. Connecting switching outputs
The switching outputs are depending on the device’s configuration of the selected output func-
tions. (see chapter 4.2)
Hint: In order to avoid unwanted or wrong switching processes, we suggest to connect the
device’s switching outputs after you have configured the device’s switching outputs
properly.
Please take care that you must not exceed the limits of the voltage and of the maximum current
of the switching outputs (not even for a short period of time).
Please take extreme care when switching inductive loads (like coils or relays, etc.) because of
their high voltage peaks, protective measures to limit these peaks have to be taken.
When switching large capacitive loads a series resistor for current limitation is needed, because
of the high turn-on-current of high capacitive loads. The same applies to incandescent lamps,
whose turn-on-current is also quite high due to their low cold resistance.

minimum or maximum alarm value was active for the delay-time you have set.
- Press button 1 to validate the delay time. The display shows “A.dEL“ again.
Example: You want to have an alarm monitoring for the cooling chamber mentioned above. The alarms
should start when the temperature will be rising above –15°C or falling below –30°C. Therefore
you have to select –15°C for the maximum alarm-value “Al.Hi“ and –30°C for the minimum alarm-
value “AL.Lo“.
The alarm will be starting after the temperature rises above –15°C and stays above –15°C for the
entered delay time or after it had been falling below –30°C and stays below –30°C for the entered
delay time.
Please note that the alarm-outputs are inverted! This means, that the output will be active if there is no
alarm!
Now you finished configuring your device. Press button 1 to switch over to display the measuring value.

- When pressing button 1 again, the device will be displaying “A.dEL“. (delay of the alarm-function)
- Use button 2 and button 3 to set the desired delay of the alarm function.
Note: The unit of the value to be set is in [sec.]. The device will turn on the alarm after minimum
or maximum alarm value was active for the delay-time you have set.
- Press button 1 to validate the delay time. The display shows “A.dEL“ again.
Example: You want to have a temperature alarm-monitoring of a greenhouse. The alarm should start when
the temperature rises above 50°C or falls below 15°C.
Therefore your settings will be 50°C for the maximum alarm-value “AL.HI“ and 15°C for the mini-
mum alarm-value “AL.Lo“.
The alarm will be starting after the temperature rises above 50°C and stays above 50°C for the
entered delay time or after it had been falling below 15°C and stays below 15°C for the entered
delay time.

for vernier adjustment of the used transducer or transmitter.
Please note: The settings of the offset- / slope-adjustment will be cancelled, when no button was pressed
for more than 60 sec. Changes you may have made already won‘t be saved and will be lost!
Hint: The buttons 2 and 3 are featured with a ‘roll-function‘. When pressing the button once the value will be raised
(button 2) by one or lowered (button 3) by one. When holding the button pressed for longer than 1 sec. the
value starts counting up or down, the counting speed will be raised after a short period of time.
The device also features a ‘overflow-function‘, when reaching the upper limit the device switches to the lower
limit, vice versa.
- turn on the device and wait after it finished its built-in segment test.
- Press button 3 > 2 sec.
The device will be displaying “OFFS“ (offset).

The input of the offset will be in digits
The value that had been set will be subtracted from the measured value. (see below for further information)
- Press button 1 to validate your selection. The display shows “OFFS“ again.
- When pressing button 1 again, the device will be displaying “SCAL“. (scale = slope)
- Use button 2 and button 3 to select the desired slope-adjustment.
The slope adjustment will be entered in %. The value displayed can be calculated like this:
Displayed value = (measured value – zero point offset) * (1 + slope adjustment [% / 100]).
Example: The setting is 2.00 => the slope has risen 2.00% => slope = 102%.
When measuring a value of 1000 (without slope-adjustment) the device would display 1020 (with slope
adjustment of 102%)
- Press button 1 to validate the selection of the slope-adjustment. The display shows “SCAL“ again.
Now you finished configuring the device’s offset and slope adjustment. Press button 1 to switch over to dis-
play the measuring value.
Example for offset- and slope-adjustment:
Example 1: Connecting of a thermocouple probe (with offset deviation)
The device displays the following values (without offset- or slope-adjustment): at 0°C = 2°C, at 100°C = 102°C
Therefore you calculated: Zero point: 2
slope: 102 – 2 = 100 (=> deviation = 0)
You have to set: offset = 2 (= zero point deviation)
scale = 0.00
Example 2: Connecting of a 0-50mV-pressure transducer
The device displays the following values (without offset- or slope-adjustment): at 0 bar = 0.08, at 20 bar = 20.02
Therefore you calculated: zero point: 0.08
slope: 20.02 – 0.08 = 19.94
deviation: 0.06
(= target slope – actual slope = 20.00 - 19.94)
You have to set: offset = 0.08 (= zero point deviation)
scale = 0.30 (= target slope / actual slope = 0.06 / 19.94 = 0.0030 = 0.30% )
7. Min-/max-value storage:
The device features a minimum/maximum-value storage. In this storage the highest and lowest measured value
is saved.
Calling of the minimum-value press button 3 shortly the device will display “Lo“ briefly, after that
the min-value is displayed for about 2 sec.
Calling of the maximum-value press button 2 shortly the device will display “Hi“ briefly, after that
the max-value is displayed for about 2 sec.
Button 1 Button 2 Button 3
Erasing of the min/max values press button 2 and 3 for 2 sec. The device will display “CLr“ briefly, after
that the min/max-values are set to the cur-
rent displayed value.
