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-pointcontroller 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 deactivated.
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 kΩ referring to +3.3V) is connected 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 kΩ referring 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 voltage 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 frequencyand 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 output of the device).

Hint: When connecting the device, take care not to exceed the limits of the input-voltage or the inputcurrent of the frequency input.

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).

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.

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.
Now you finished the offset and slope adjustment of your device. Press button 1 to switch over to display the measuring value.
Examples for offset- and slope-adjustment:
Example1: Connecting a Pt1000-sensor (with an offset error depending on the cable-length of the sensor)
The device displays the following values (without offset- or slope-adjustment): 2°C at 0°C and 102°C at 100°C
Therefore you calculated: zero point: 2
slope:
102 – 2 = 100 (deviation = 0)
You have to set:
offset =
2
(= zero point-deviation)
scale =
0.00
Example2: Connecting of a 4-20mA-pressure-transducer
The device displays the following values (without offset- or slope-adjustment): 0.08 at 0.00 bar and 20.02 at 20.00 bar
Therefore you calculated: zero point: 0.08
slope:
20.02 – 0.08 = 19.94
deviation: 0.06
(= target-slope – actual slope = 20.00 - 19.94)
You have to set:
offset =
0.08
(= zero point-deviation)
scale =
0.30
(= deviation / actual slope = 0.06 / 19.94 = 0.0030 = 0.30% )
Example3: Connecting of a flow-rate-transducer
The device displays the following values (without offset- or slope-adjustment): 0.00 at 0.00 l/min and 16.17 at 16.00 l/min
Therefore you calculated: zero point: 0.00
slope:
16.17 – 0.00 = 16.17
deviation: -0.17
(= target-slope – actual slope = 16.00 - 16.17)
You have to set:
offset =
0.00
scale =
-1.05
(= deviation / actual slope = -0.17 / 16.17 = -0.0105 = -1.05% )
