Introduction

The GIR 230 Pt is a microprocessor-controlled displaying, monitoring, and controlling device.
The device supports one interface for the connection of:

• * NTC, 10k (2-wire-technology)

• The device features two switching outputs (1 Relays, 1 NPN-Output), which can be configured as 2-point-controller, 2-point-controller with min./max. alarm, or just individual min./max. alarm.
• The state of the relay output is displayed with the left LED beneath the front 4-digit LED-display.
• If there is an alarm condition the display alternates between value and AL.Lo or AL.Hi.
• When leaving factory the GIR230NTC has been subjected to various inspection tests and is completely cali-brated.
• Before the GIR230NTC can be used, it has to be configured for the customers applications.
• 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.

Electrical connection

Wiring and commissioning of the device must be carried out by skilled personnel only.
In case of wrong wiring the device may be destroyed. We can not assume any warranty in case of wrong wiring of the device.

Terminal assignment

Connection data

These limits must not be exceeded (not even for a short time) !

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..

Connecting a NTC transmitter

Connecting switching outputs

The switching outputs are depending on the device’s configuration of the selected output func-tions.

Hint: In order to avoid unwanted or wrong switching processes, we suggest connecting the devices 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.

Configuration of the device

Please note : When you are configuring the device and dont press any button for more than 60 sec. the configuration of the device will be canceled. The changes you made will not 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 press 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 an overflow function, when reaching the upper limit of the range, the device switches to the lower limit, and vice versa.

•  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 start 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.

• Please note that the alarm outputs are inverted! This means, that the output will be active when there is no alarm!Now you finished configuring your device. Press button 1 to switch over to display the measuring value.

Min-/Max-alarm display

The device features a minimum/maximum-value storage. In this storage, the highest and lowest measured value are saved.

If an output function with alarm (out = 2P.AL or AL) is selected and there is an alarm condition the display alternates between measuring value and AL.Lo or AL.Hi
Min.-alarm: approx. all 2 sec. AL.Lo will be shown in the display
Max.-alarm : approx. all 2 sec. AL.Lo will be shown in the display

Min-/max-value storage

• Calling of the minimum-value press button 3 shortly
• Calling of the maximum-value press button 2 shortly
• Erasing of the min/max values press buttons 2 and 3 for 2 sec.

the device will display Lo briefly, after that the min-value is displayed for about 2 sec.
the device will display Hi briefly, after that the max-value is displayed for about 2 sec.
The device will display CLr briefly, after that the min/max values are set to the current displayed value.

Offset- and slope-adjustment

The offset and slope-adjustment function can be used for compensating the tolerance of the used probes.
Please note : The settings of the offset- / slope adjustment will be canceled, when no button was pressed for more than 60 sec. Changes you may have made already wont 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).
• Use button 2 and button 3 for setting the desired zero point offset-value.

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 display 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.
  Example for offset- and slope-adjustment:
  Example : Connecting an NTC-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 = 0.5°C, at 100°C = 100.5°C Therefore you calculated: zero point: 0.5

• 100.5  0.5 = 100.0 (=>deviation = 0)

• You have to set: the slope : offset = 0.5 (= zero point deviation)

• scale = 0.00
