2. Introduction
The GIA 2000 is a microprocessor controlled displaying device.
The GIR 2002 is a microprocessor controlled displaying,
monitoring and controlling device.
The devices supports one universal interface for the connec-
tion of:
- Standard transmitter signals (0-20mA, 4-20mA, 0-50mV,
0-1V, 0-2V and 0-10V),
- RTD (for Pt100 and Pt1000),
- Thermocouple probes (type K, J, N, T and S),
- Frequency (TTL and switching contact).
As well as flow rate and rotation measuring, counting, etc. ...
The GIR 2002 features additionally one or two switching outputs, which can be configured as
2-point-controller or min./max. alarm (one switching output) or
2-point-controller, 3-point-controller, 2-point-controller with min./max. alarm, common or individual
min./max. alarm (two switching outputs)
The state of the switching outputs (relays) is displayed with the LED’s “1” and “2”.
An upcoming alarm condition is displayed by LEDs “alarm”, “max” and “min”.
The devices with option AAG are additionally equipped with a scaleable analog output (0-10V, 0-20mA or 4-20mA).
Furthermore both devices supports one EASY
BUS -interface for communicating with a host computer that
makes the device to a full functions EASY
BUS -module.
When leaving our factory the GIA 2000 and GIR 2002 has been subjected to various inspection tests and is
completely calibrated.
Before the GIA 2000 or GIR 2002 can be used, it has to be configured for the cus-
tomer’s application.
Important: At the configuration of the device You have to adjust the input signal (see chapter 4) first and
then the analog output function (if available - see chapter 5), the output function (see chapter 6) or the offset-
/slope- adjustment (see chapter 8).
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
analog output, configuration of the output function, offset- and slope-adjustment) the meas-
urement 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.

3.4.6. Connecting a 0-1V, 0-2V or 0-10V or 0-50mV transmitter (4-wire-system)
with integrated power supply with separate power supply
3.4.7. Connecting a frequency signal
When measuring frequency or rotation three different input signals can be selected in the device’s configu-
ration. 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 +Ub, high-side push-button, ...).
When configuring the device with a NPN switching output, a pull-up-resistor (~7k referring to +3.3V) is con-
nected internally. So when You are using 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 (~7k referring to GND) is con-
nected internally. So when You are using 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 de-
vice 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.

(Rv1 is a current limiting resistor and may be shorted if necessary. It should never exceed the mentioned value.)
3.4.8. 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 chapter 3.4.7.
There is the possibility to reset the counter. When connecting contact 11 with GND (contact 10) 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 – if available).
Hint: When connecting the device, take care not to exceed the limits of the input-voltage or the input-
current of the frequency input.

3.5. Connecting switching outputs (only for GIR 2002)
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 one switching output (relay) or two switching outputs (relays) by default.
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, protec-
tive measures (e.g. RC-element) to limit these peaks have to be taken.
Note: In case of configuring one output as an alarm output, the output will be active in idle state (no
alarm present). The output relay opens when an alarm condition occurred.
3.6. Common wiring of several devices
At the standard devices the power supply, measuring input, transmitter supply and the serial interface are
electrically isolated of each other.
At device options (e.g. dc-supply) it can occur that this isolation is not completely guaranteed (e.g. connec-
tion of – power supply to GND).
When interconnecting several of this devices you have to make sure that there is no potential displacement.
4. Configuration of the measuring input
General description and notes to the operating of the menu
By means of button 1 you can go to the next parameter.
Additionally a given changing in the parameter setting can be confirmed by this button and the new value
will be saved. Afterwards it will be changed to the parameter view again
By means of button 2 or button 3 you can go from the parameter view to the parameter setting and adjust
its value there.
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.
By means of button 4 a given changing will be cancelled in the parameter setting. The changing will be
discarded and the former parameter value will be preserved.
In the parameter view button 4 closes the menu.
Please note: If you don’t press any button for more than 10 sec. in the parameter setting, the adjustment will be
cancelled, the changing discarded and it will be changed to the parameter view. If you don’t press
any button for more than 60 sec. in the menu, the menu will be automatically closed.

4.1. Selecting an input signal type
- Turn the device on and wait until it completed its built-in seg-
ment test.
- At the same time press the pushbutton on the rear side (but-
ton 5) and button 2 for >2 seconds.
The device displays “InP“ ('INPUT').
- Use button 2 or button 3 to select the input signal
(see table below).
- Validate the selection with button 1 . The display will show “InP“ again.
Depending on the selected input signal, additional configurations will be needed.

Please note: When changing the measuring mode “InP“ all settings will be reset. Therefore you have
to set all the other settings of the input configuration again.
Note: When changing the measuring mode “InP“ the values for the offset and slope-adjustment will
be reset. Furthermore a change of the device scaling for standard signals (di.Lo, di.Hi, dP) or
of the resolution and unit for temperature can possibly influence the values of the offset and
slope-adjustment. Therefore you may check your offset and slope-adjustment after changing
the input configuration.
The change of the device scaling for standard signals (di.Lo, di.Hi, dP) or of the resolution
and unit for temperature can possibly change the switching and alarm points. Therefore you
may check your output settings afterwards.

4.2. Measuring temperature (Pt100, Pt1000 RTD probes and thermocouple type J, K, N, S or T)
This chapter describes how to configure the device for temperature measuring with the help of external plati-
num RTD probes or thermocouple probes. This instruction demands that you selected “t.res“ or “t.tc“ as your
desired input type like it is explained in chapter 4.1. The device has to display “InP“.
- When pressing button 1 the display shows “SEnS“.
- Use button 2 or button 3 to select your desired input signal.

The incoming pulses will be divided with the selected pre-scaling factor, after that they will be transmitted to the de-
vice for further processing.
By this factor you can adapt the device to your transmitter or select a pre-scaling factor for large values
Example 1: Your flow rate transmitter supplies 165 pulses per litre. When setting a pre-scaling factor of 165 every
165th pulse (so 1 pulse per litre) will be used for further processing.
Example 2: Your transmitter is supplying about 5 000 000 pulses during the measurement, which exceeds 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
.

count is reached.
Example: Your flow rate transmitter is supplying 1800 pulses per litre and you are expecting a maximum 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 set the decimal point position to ---.- and a display
range limit of 300.0.
