2 Intended Use
The GIR 300 is a microprocessor controlled displaying, monitoring and controlling device..
The device is supporting one universal interface for the connection of:
- Standard transmitter signals (0-20 mA, 4-20 mA, 0-50 mV, 0-1 V, 0-2 V
and 0-10 V),
- RTD (Pt 100 and Pt 1000),
- Thermocouple probes (type K, J, N, T and S)
- Frequency (TTL and switching contact)
As well as rotation measuring, counting, etc...
The device features two switching outputs, which can be configured as 2-point-controller, 3-point-controller, 2-point-
controller with min./max. alarm, common or individual min./max. alarm.
The state of the switching contacts is displayed with 2 LED´s. LED “1” displays the state of the contact of relay 1 and
LED “2” displays the state of contact of relay 2. (LED illuminate = contact is closed)
Furthermore the device supports one EASYBus -interface for communicating with a host computer that makes the
device to a full functions EASYBus-module.
When leaving our factory the GIR 300 has been subjected to various inspection tests and is completely calibrated.
Before the GIR 300 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 suggest
to connect the device’s switching outputs after You have configured the device properly.
Hint: By calling a configuration menu (configuration of the measuring input, configuration of the output
function, offset- and slope-adjustment) the measurement and regulation of the device will be deac-
tivated.
By leaving the menu the device will be reinitialised and the measuring/regulation will be started
again.
At the input function “counter” the counter state will be reset by leaving the menu.

4.3.6 Connecting a frequency- or rotation-signal
When measuring frequency or rotation three different input signals can be selected in the device’s configuration.
There is the possibility of connecting an active signal (= TTL, ...), a passive sensor-signal with NPN
(= NPN-output, push-button, relay, ...) or PNP (= a PNP output switching to +Us, high-side push-button, ...)
When configuring the device with a NPN switching output, a pull-up-resistor (~7 kΩreferring to +3.3V) is con-
nected internally. So when you use a device with NPN output you don‘t need to connect a resistor externally.
When configuring the device with a PNP switching output, a pull-down resistor (~7 kΩreferring to GND) is connected
internally. So when you use a device with PNP output You don‘t need a resistor externally.
It may be that your measuring-signal source needs the connection of an external resistor e.g. the pull-up-voltage
of 3.3V is not enough for the signal source, or you want to measure in the top level frequency range. In this case
the input signal has to be treated like an active signal and you have to configure the device as „TTL“.
Hint: when connecting the device You have to take care not to exceed the limits of the input volt-
age respective the input current of the frequency-input.

4.3.7 Connecting a counter signal
When configuring the device you can select 3 different input signal modes similar to the connection of frequency-
and rotation-signals.
The connection of a sensor-signal for a counter-signal is the same used for the frequency- and rotation-signal.
Please use the wiring diagram given in this chapter.
There is the possibility to reset the counter. When connecting contact 4 with GND (e.g. contact 6) the counter will
be reset. You can do this manually (e.g. with the help of a push-button) or automatically (with one switching out-
put of the device).
Hint: When connecting the device, take care not to exceed the limits of the input-voltage or the input-
current of the frequency input.



E44.X.00.6C-03 Connection and operating manual GIR 300 page 10 of 28
4.4 Connecting switching outputs
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.
The device features 2 switching outputs by default
• output 1: relay, make contact
• output 2: relay, break contact
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 (e.g. RC-element) to limit these peaks have to be
taken.
Note: You will find detailed information to the switching states of the different output functions in chapter 6
(“Switching points and alarm-boundaries“)
Note: In case of configuring one output as an alarm output, the relay contact will be closed at the idle state (no
alarm is present). If an alarm condition will occurred the relay contact will be opened.
(for detailed information please refer the notes in chapter 6.2 and 6.3)
4.5 Common wiring of several devices
The input of the device are not electrically isolated to the power supply.
When interconnecting several device`s you have to make sure that there is no potential displacement
Make sure to observe the following points:
- When several devices are connected to the same power supply unit it is highly recommended to isolate the sensors,
measuring transducers etc.
- When the sensors, measuring transducers etc. are electrically connected, and you can’t manage to isolate them, you
should use separate electrically isolated power supply units for each devices.
Please note, that an electric connection may also be created via the medium to be measured (e.g. pH-electrodes
and conductivity-electrodes in fluids).


E44.X.00.6C-03 Connection and operating manual GIR 300 page 11 of 28
5 Configuration
Please note: When you are configuring the device and don’t press any button for more than 60 sec.
the configuration of the device will be cancelled. 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 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 of the range, the device
switches to the lower limit, vice versa.
5.1 Selecting an input signal type
- Turn the device on and wait until it completed its built-in segment test.
- Press button 2 for >2 sec. (e.g. with a small screw driver)
The device displays “InP“ ('INPUT').
- Use button 2 or button 3 (middle or right button) to select the input
signal (see table below).
- Validate the selection with button 1 (the left button). The display will
show “InP“ again
Depending on the selected input signal, additional configurations will be needed.

Example 2: Your transmitter is supplying about 5 000 000 pulses during the measurement, which ex-
ceeds the limit of the device.
But when setting a pre-scaling factor of 1000 only every 1000th pulse is used for further
processing. So you only got a value 5000 which won’t exceed the limit of the device.

of 100 and you are expecting a maximum flow rate of 300 litres during the measurement.
With a pre-scaling factor of 100 selected, you will get 18 pulses per litre.
With a maximum flow rate of 300 litres you will be getting a pulse count of 18 * 300 = 5400.
- Press button 1 to validate your selection. The display shows “Co.Hi“ again.
- When pressing button 1 again, the device will be displaying “dP“ (decimal point).

mum flow rate of 300 litres. You selected a pre-scaling factor of 100 and a counter range
limit of 5400.
When wanting a resolution of 0.1 litres shown in the display of the device you would have to
