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

3.4. Connecting switching outputs
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 input of the offset will be in digits. The value that had been set will be subtracted from the measured value of input 2.
- Press button 1 to validate your selection. The display shows “OFS.2“ again.
- When pressing button 1 again, the device will be displaying “SCA.2“. (scale 2 = slope of input 2)
- 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 2 = (measured value input 2 – zero point offset 2) * (1 + slope adjustment 2 [% / 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 “SCA.2“ again.
Now you finished configuring the device’s offset and slope adjustment. Press button 1 to switch over to dis­play the measuring value.
Example for offset- and slope-adjustment:
Example: Connecting a temperature probe (offset deviation depending on using long wires between probe and device)
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)
