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)
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 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 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.
