1. Safety regulations
This device was designed and tested considering the safety regulations for electronic measuring devices.
Faultless operation and reliability in operation of the measuring device can only be assured if the General
Safety Measures and the devices specific safety regulations mentioned in this users manual are considered.
1. Faultless operation and reliability in operation of the measuring device can only be assured if the device
is used within the climatic conditions specified in the chapter “Specification“
2. Always disconnect the device from its supply before opening it. Take care that nobody can touch any of
the devices contacts after installing the device.
3. Standard regulations for operation and safety for electrical, light and heavy current equipment have to be
observed, with particular attention paid to the national safety regulations (e.g. VDE 0100).
4. When connecting the device to other devices (e.g. the PC) the interconnection has to be designed most
thoroughly, as internal connections in third-party devices (e.g. connection of ground with protective earth)
may lead to undesired voltage potentials.
5. The device must be switched off and must be marked against re-starting, in case of obvious malfunctions
of the device which are e.g.:
- visible damage.
- the device is not working as prescribed.
- after storage of the device under inappropriate conditions for longer time.
In case of doubt, the device should be sent to the manufacturer for repairing or servicing.
ATTENTION: When running electric devices, parts of them will always be electrically
live. Unless the warnings are observed serious personal injuries or damage to property may result. Skilled personnel only should be allowed to work with this device. For
trouble-free and safe operation of the device please ensure professional transport,
storage, installation and connection as well as proper operation and maintenance.
SKILLED PERSONNEL
Are persons familiar with installation, connection, commissioning and operation of the product and have
professional qualification relating to their job.
For example:
• Training or instruction respectivley qualifications to switch on or off, isolate, ground and mark electric circuits and devices or systems.
• Training or instruction according to the state.
• First-aid training.
ATTENTION:
Do NOT use this product as safety or emergency stopping device, or in any other application where failure of the product could result in personal injury or material damage.
Failure to comply with these instructions could result in death or serious injury and
material damage.

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.
In case of wrong wiring the device may be destroyed. We can not assume any warranty in case of
wrong wiring of the device.

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..

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.
