1 Designated Use
The GIA 0420 N and GIA 010 N are microprocessor controlled display devices.
The different design types of the device have an input for:
- standard signal 4 –20 mA (GIA 0420 N)
- standard signal 0 –10 V (GIA 010 N)
The measuring value is displayed on a 4-digit LCD display with max. display area ranging from -1999 to +9999 digits.
The device additional features a switching output (NPN-output) which can be configured as 2-point controller or min-
/max alarm. The state of the output is displayed with an arrow at the LCD.
The GIA 0420 … is designed for the connection of any measuring transducers (with a 4 to 20 mA output).
This design type doesn't need an auxiliary supply as it is supplied by the measuring current.
The GIA 010 … is designed for the connection of any measuring transducers (with a 0 - 10 V output).
The parameters and limit values can be input by buttons accessible at the rear side.
The operating range of the display device can be directly adjusted to the transmitter without any additional accesso-
ries by simply entering the maximum and minimum measuring range limits as well as the decimal point position.
All programmable parameters of the device are saved in an EEProm. In case of a current failure they will remain there
for at least 10 years.
The device is equipped with a self-diagnosis system continuously monitoring the essential parts of the device for their
perfect functioning. Both the self-diagnosis and the measuring sensor monitoring for values exceeding or falling below
permissible limits ensure maximum operational reliability of the device.
Prior to delivery the device will be tested and completely calibrated.
However, prior to you starting your operation make sure to configurate the device for your application.
Please also refer to chapter "Configuration".
2 General Note
Read this document carefully and get used to the operation of the device before you use it. Keep this document within
reach for consulting in case of doubt.

3 Safety Requirements
3.1 General safety advices
This device has been designed and tested in accordance with the safety regulations for electronic devices.
However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and
special safety advises given in this manual will be adhered to when using the device.
1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected to any
other climatic conditions than those stated under “Specification”.
2. Standard regulations for operation and safety for electrical, light and heavy current equipment have to be ob-
served, with particular attention having to be paid to national safety regulations (e.g. VDE 0100).
3. When connecting the device to other devices (e.g. PC) the interconnection has to be designed most thoroughly as
internal connections in third-party devices (e.g. connection GND with protective earth) may lead to undesired volt-
age potentials.
4. If there is a risk whatsoever involved in running it, the device has to be switched off immediately and to be marked
accordingly to avoid re-starting.
Operator safety may be a risk if:
- there is visible damage to the device.
- the device is not working as specified.
- the device has been stored under unsuitable conditions for a longer time.
In case of doubt, please return device to manufacturer for repair or maintenance.
5. The buttons at the rear side are necessary for the configuration of the device.
The device is ESD sensitive at this area!!
The configuration must be done considering adequate ESD safety measures!
6. Warning: Do not use these products as safety or emergency stop devices 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.
7. This device must not be used at potentially explosive areas! The usage of this device at potentially explosive areas
increases danger of deflagration, explosion or fire due to sparking.
8. This device is not constructed for use in medical applications.
9. This device must not be run with a defective or damaged power supply unit. Danger to life due to electrical shock!
3.2 Skilled Personnel
Are persons familiar with installation, commissioning and operation of the product and have professional qualification
relating to their job.
For example:
•Training or instruction resp. Qualification 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.
4 Disposal Notes
The device must not be disposed in the unsorted municipal waste!
Send the device directly to us (sufficiently stamped), if it should be disposed.).
We will dispose the device appropriate and environmentally sound.
E42.X.1X.6C-02 Operating Manual GIA 0420 N / GIA 010 N page 4 of 10
5 Electric connection
The GIA ... N is connected via screw-type/plug-in terminals on the rear side.
General Note: Screw-type/plug-in terminals have to be mounted while they are still loose and plug them in only
afterwards. Soldering lands may be damaged in case of improper assembly of already plugged
terminals.
Please use applicable screwdriver and do not forcibly tighten the screws.
Supply voltage: GIA 0420 N device takes power from measuring current
GIA 010 N 12 ... 28 V or according device declaration
Electric connection and commissioning of the device must be carried out by trained and skilled personnel.
Wrong connection may lead to the destruction of the display device, in which case we cannot assume any warranty!
! Mind for the GIA 0420 … the maximum input current rating of 40mA under any circumstances !

8 Offset and slope adjustment
Note: The device can be ESD sensitive at the area of the buttons.
The configuration must be done considering adequate ESD safety measures!
The offset and slope-adjustment function can be used for compensating the tolerance of the used sensor, resp. for
vernier adjustment of the used transducer / transmitter.
Follow these instructions to run the offset and slope adjustment of the device:
Press button 3 for 2 seconds during actual value display, „OFFS“ is displayed.
Set parameter value with button 2 and button 3.
Save the set with button 1, the parameter name is displayed again.
Proceed to the next parameter with button 1, the name of that parameter is dis-
played.

OFFS
Offset
-5.00 …5.00
The offset in digit
The set offset value is subtracted from measured value.
SCAL
Scale
-5.00 …5.00
The scale in %.
The displayed value is calculated according to the following formula:
Display = (measured value - offset - di.Lo) * (1 + slope adjustment [% / 100] ) + di.Lo
Example for offset and slope adjustment:
Connection of pressure transmitter.
The device displays without offset and slope adjustment: at 0 bar = 0.08, at 20 bar = 20.02
From this calculated: offset: 0.08
slope: 20.02 –0.08 = 19.94
difference: 0.06 (= ideal slope –actual slope = 20.00 - 19.94)
Therefore this values should be set: offset = 0.08
scale = 0.30 (= difference / actual slope = 0.06 / 19.94 = 0.0030 = 0.30% )
9 Min-/max- value memory
The device features a minimum/maximum-value storage. In this storage the highest and lowest performance data is
saved.
Calling of the minimum value:
Press button 3 shortly: the device will display “Lo“ briefly, after that the min-value is displayed for about 2 sec.
Calling of the maximum value:
Press button 2 shortly: the device will display “Hi“ briefly, after that the max-value is displayed for about 2 sec.
Erasing of the min/max values:
Press button 2 and 3 for 2 sec.: The device will display “CLr“ briefly, after that the min/max-values are set to the cur-
rent displayed value.
