2. Introduction
The GIR 2002 is a microprocessor controlled displaying, moni-
toring and controlling device.
The device supports one connection facility for:
- Standard transmitter signals (only 1 signal type possible)
2x 0-20mA, 2x 4-20mA or 2x 0-10V)
Display and control are based on the difference of the two
measuring inputs (input 1 input 2).
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 devices with option AAG are additionally equipped with a scaleable analog output (0-10V, 0-20mA or 4-20mA).
Furthermore both devices 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 GIA 2000 and GIR 2002 has been subjected to various inspection tests and is
completely calibrated.
Before the GIR 2002 can be used, it has to be configured for the customer’s applica-
tion.
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. 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.
3.4.1. Connecting a 0(4)-20mA transmitter (2-wire- system)
with integrated power supply with separate power supply
3.4.2. Connecting a transmitter (3-wire- system)
with integrated power supply with separate power supply
3.5. 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 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 these devices you have to make sure that there is no potential displace-
ment.

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.

Note: If the digital filter is “off” the internal mains hum suppression of the GIR2002 is deactivated.
This adjustment is ideal for fastest response to even small changes of the signal, but the display
and the analog output gets more turbulent. Therefore the filter should set to at least 0.01 for „ordi-
nary‟ application .

Now your device is adjusted to your input signal.
- Press now button 4 to exit the input configuration menu.
5. Configuration of the analog output (only at devices with option AAG)
A change of the input configuration can possibly influence the configuration of the analog output.
(e.g. changing of scaling for standard signals or changing of resolution or unit for temperature)
Therefore the analog output configuration should be done after the input configuration has been
finished.
Additionally you may check your analog output settings after the input configuration has been
changed.
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

Note: The “dA.Fi” value can only be set for the input signal types “voltage”, “current” and “fre-

(equal to: “filter value” = „disp„, see following „explanation‟) and the scaling continuous with
the point “dA.Er“(see below).
- Use button 2 or button 3 to select the desired filter value
Explanation: The analog output corresponds directly to the displayed value if the filter value = „disp„,
i.e. the filter for the display (set in the „configuration of the measuring input‟) takes effect on
the analog output. The resolution of the analog output depends on the scaling of the display.
With a filter value > 0 the analog output is independent of the filter for the display and it has
the highest possible resolution no matter how the display is scaled.
With a small filter values the analog output responds faster to changes of the signal, but the
analog output gets more turbulent. With a high filter value the analog outputs „smoothed‟, but
it responds to changes of the signal delayed.

6. Configuration of the output functions (only for GIR 2002)
A change of the input configuration can possibly influence the switching points and alarm bounda-
ries. (e.g. changing of scaling for standard signals)
Therefore the output configuration and switching points / alarm boundaries adjustment should be
done after the input configuration has been finished.
Additionally you may check your output settings after the input configuration has been changed.
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 con-
firmed 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

7. Switching points and alarm-boundaries
Remark: The difference between this menu and the output configuration menu is that only in the output
configuration menu it is possible to select the output function and to adjust the delay and the
preferred state of switching functions.
A change of the input configuration can possibly influence the switching points and alarm boundaries. (e.g.
changing of scaling for standard signals or changing of resolution or unit for temperature)
Therefore you may check your output settings after the input configuration has been changed.
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 con-
firmed 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 dis-
carded 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.

Example: You want to control the temperature of a heating coil, with a hysteresis of +2°C, to 120°C. There-
fore you will have to select the turn-on-point “1.on“ to 120°C and the turn-off-point to “122°C“. When
your heating coil temperature falls below 120°C it will be turned on. When the temperature rises
above 122°C the heating coil will be turned off.
Note: Depending on the inertia of your heating coil an overshooting of the temperature may be possible.

Example: You want to control the temperature of a cooling chamber between –20°C and –22°C.
Therefore you will have to select –20°C for the turn-on-point 1 “1.on“ and –22°C for the turn-off-
point 1 “1.off“. When the temperature rises above –20°C the device turns its output 1 on, when
falling below –22°C the device will turn its output 1 off .
Note: Depending on the inertia of your cooling circuit an overshooting of the temperature may be possible.

9. Serial interface
The device features one EASYBus-Interface. You can use the device as a full function EASYBus-device.
The serial interface allows the device to communicate with a host computer. Data polling and data transfer is
done in master/slave mode, so the device will only send data on demand. Every device has a unique ID-
number that makes exact identification of each device possible. With the help of a software (like EbxKonfig 
freeware version available via internet) you are able to reassign an address to the device.
Additional accessories needed for the interface mode:
- Interface converter EASYBus PC: e.g. EBW1, EBW3, EBW64, EB2000MC
- Software for communication with the device
EBS9M: 9-channel-software for displaying a measured value.
EASYCONTROL: universal multi-channel software for real-time-recording and displaying measure-values of
a device in ACCESS®-database-format.
EASYBUS-DLL: EASYBUS-developer-package for developing own software. This package features a
universal WINDOWS®-Library with documentation and program-examples. The DLL
can be used in any usual programming language.
