2. Introduction
GIR230 Pt1000 / DIF and the GIR230 NTC / DIF is a microprocessor controlled displaying, monitoring and
controlling device.
The device is supporting two interface for the connection of:
- Pt1000 (2-wire-technology) at type GIR230 Pt1000 / DIF
- NTC (2-wire-technology) at type GIR230 NTC / DIF
The display and regulation will occur to the difference (sensor 1 – sensor 2)
of the both measuring inputs.
The device features three switching outputs (2 * Relays, 1 * NPN-Output), which can be configured as 2point-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 with 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.
If there is an alarm condition the display alternates between value and AL.Lo or AL.Hi.
When leaving factory the GIR230 has been subjected to various inspection tests and is completely cali-
brated.
Before the GIR230 can be used, it has to be configured for the customer’s application.
Hint: In order to avoid undefined input states and unwanted or wrong switching processes, we sug-
gest to connect the device’s switching outputs after You have configured the device properly.
3. Electrical connection

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..
The switching outputs are depending on the device’s configuration of the selected output functions. (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.

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
scale = 0.00
(= zero point deviation)
