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

Wiring and commissioning of the device must be carried out by skilled personnel only.

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.

- When pressing button 1 again, the device will be displaying “1.off“. (turn-off-point of output 1)

- Use button 2 and button 3 to set the desired value, the device’s output 1 should be turning off.

- Press button 1 to validate your selection. The display shows “1.off“again.

Example: You want to control the temperature of a cooling chamber between –20°C and –22°C.

Therefor you will have to select –20°C for the turn-on-point 1 “1.on“ and –22°C for the turn-offpoint 1 “1.off“. When the temperature rises above –20°C the device turns its output 1 on, when falling below –22°C the device will turn its output 1 off .

Note: Depending on the inertia of your cooling circuit an overshooting of the temperature may be possible.

When selected '3-point-controller with alarm function', you have to select the switching points for the second switching function (“2.on“, “2.off“). Configuring these settings like the first switching function. After that the alarm outputs have to be configured.

- When pressing button 1, the device will be displaying “AL.Hi“. (maximum alarm-value)

- Use button 2 and button 3 to set the desired value, the device should turn on its maximum-alarm.

- Press button 1 to validate your selection. The display shows “AL.Hi“ again.

- When pressing button 1 again, the device will be displaying “AL .Lo“. (minimum alarm-value)

- Use button 2 and button 3 to set the desired value, the device should turn on its minimum-alarm

- Press button 1 to validate your selection. The display shows “AL.Lo“ again.

- 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 [0 .. 9999] is in seconds. The device will turn on the alarm after

the 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.
