Introduction
The GIA0420 is a microprocessor controlled display device for 4 to 20 mA standard signal that can be
universally applied. It does not require its own auxiliary voltage source but can be supplied directly from
the measuring current.
Themeasuringvalueisdisplayedona4-digitLCDdisplaywiththemax.displayarearangingfrom-1999to+9999digits.
The GIA0420 is designed for the connection of any measuring transducers (with a 4 to 20 mA output). The
operating range of the display device can be directly adjusted to the transmitter without any accessories
being required by simply entering the maximum and minimum measuring range limits as well as the
decimal point position.
Parameter and limit values are entered via three keys located at the back side of the device.
The front side of the display is splash-water and wipe resistant, thus conforming to the IP65 requirements.
All programmable parameters of the GIA0420 are saved in an EEProm; in case of a current failure they will
remain there for at least 10 years.The GIA0420 is equipped with a self-diagnosis system continuously
monitoring the essential parts of the device for their perfect funtioning. Both the self-diagnosis and the
monitoring system for the measuring sensor for "sensor damage" and "short circuit in sensor" or values
exceeding or falling below permissible limits ensure maximum operational reliability of the device.
Prior to delivery the GIA0420 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".
Attention: When running electric devices parts of these devices will always be highly
energised. Unless the warnings are observed serious personal injuries or
damage to property may result. Skilled personnel only should be allowed to
work with this device. For trouble-free and safe operation of the device please
ensure professional transport, storage, installation and connection as well as
proper operation an maintenance.
Safety advice
Inordertoexcludeanyriskwhatsoeverfortheoperatorthefollowingpointshavetobeobserved:
a) Immediately switch off the device in case of visible damage or obvious malfunctions.
b) Make it a rule to always disconnect voltage source and device before opening it up. The entire device
and its connection have to be fingerproof after installation.
c) Standard regulations for operation and safety for electrical, light and heavy current equipment have to
be observed, with particular attention having to be paid to national safety regulations (e.g. VDE 0100).
d) When connecting a GIA0420 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 voltage potentials.

Terminalassignment:
Electric connection
All connections for the GIA0420 are on the back side of the device.
Connection is made via screw-type/plug-in terminals.
Make it a rule to mount screw-type/plug-in terminals while they are still loose and to put them on only
afterwards. When mounting terminals already put on there is a risk that soldering eyelets may be pulled
out. Please use suitable screw driver and do not tighten screws by force.
Supply voltage: device takes power directly from measuring current
Switching output:(onlyforGIA0420SP) 1 open-collector-switching output, electrically isolated!
Switching capacity: (onlyforGIA0420SP) 3 mA, 24V DC
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 the maximum input current rating of 40mA under any circumstances !!

Fault codes
In case of unacceptable conditions in the system a fault code will be displayed.
Fault codes have been defined as follows:
FE 1: Measuring range has been exceeded
This fault code indicates that the measuring range of the A/D converter has been exceeded.
Potential fault cause: transmitter damaged
short-circuit in transmitter connection
Remedies: FE 1 will be reset as soon as the measuring values are back within their permis-
sible range. Please check your transmitter and transmitter connecting cables.
FE 2: Measuring values have fallen below permissible range
This fault code indicates that the measuring values of the A/D converter have fallen below the
permissible range.
Potential fault cause: transmitter damaged
transmitter connection interrupted
Remedies: FE 2 will be reset as soon as the measuring values are back within their permis-
sible range. Please check your transmitter and transmitter connecting cables.
FE 6: New Startup
This error message signals that the instrument is currently performing the startup sequence.
possible cause: Input current to low
Remedies: FE6 will be reset as soon as the instrument has finished its startup
sequence. Check the loop current.

Configuration
Please note: measuring current should be at least 4 mA during configuration!
1. Press button 1, "dP" (decimal point) will be displayed.
Select decimal point position desired using buttons 2 and 3.
Acknowledge decimal point position by pressing button 1. "dP" will be displayed again.
2. Press button 1 once again, "An 4" (display for 4mA) will be displayed.
Use buttons 2 and 3 to set value to be displayed on the GIA0420 for an input signal of 4mA.
Buttons 2 and 3 are equipped with a scrolling function, i.e. the value will be increased respectively
decreased by 1 digit when button 2 respectively button 3 is pressed briefly (no more than 1 s). When
pressing these buttons for a longer time (over 1 s) the values will start „scrolling“ upwards respectively
downwards with the scrolling speed being increased after approx. 6s.
Acknowledge value displayed by pressing button 1. "An 4" will be displayed again.
3. Switch over to the next parameter by pressing button 1 once again. "An20" will be displayed (display
for 20mA).
Use buttons 2 and 3 to set value to be displayed on the GIA0420 for an input signal of 20mA.
Acknowledge value displayed by pressing button 1. "An20" will be displayed again.
4. Press button 1 once again. "LI" (limit) will be displayed.
Select measuring range limits desired using buttons 2 and 3.
0=Values exceeding/falling below limits are acceptable. (FE1, FE2 displayed for hardware limits)
1= Values exceeding/falling below limits are not acceptable. (FE1, FE2 displayed for area limits)
Acknowledge selection made by pressing button 1. "LI" will be displayed again.
5. Press button 1 once again. "FILt" (filter) will be displayed.
Select input filter 0, 1, 2 or 3 desired using buttons 2 and 3.
0=no filter
1=filter 1 active
2=filter 2 active
3=filter 1 and filter 2 active
Filter 1: prevents ”jumping” of the last figure, a phenomenon often found with digital displays and
controllers. Make sure to always activate filter 2 if the display range exceeds 2000 digits.
Additional display delay: approx. 1s
Filter 2: for filtering short pikes occurring when relays and contactors are switched. Make sure to always
activate filter 1 if high loads are switched in the vicinity of the GIA0420, wires or sensor or if large pikes are to
be expected.
Additional display delay: approx. 0.5s
Acknowledge selection made by pressing button 1. "FILt" will be displayed again.
The adjustment of the GIA0420 to the transducer is now completed. Do not forget to set alarm limits and
alarm delays if you operate a GIA0420SP (with switching output). This is not necessary for GIA0420
(without switching output). The GIA0420 can be immediately switched over to display the current measuring
vlaue by pressing button 1.
6. Press button 1. "AL.HI" (max. alarm limit) will be displayed.
Use buttons 2 and 3 to set max. alarm limit.
Acknowledge alarm limit set by pressing button 1. "AL.HI" will be displayed again.
7. Press button 1 once again. "AL.Lo" (min. alarm limit) will be displayed.
Use buttons 2 and 3 to set min. alarm limit.
Acknowledge alarm limit set by pressing button 1. "AL.Lo" will be displayed again.
8. Press button 1once again. "dELA" (alarm delay) will be displayed.
Use buttons 2 and 3 to set alarm delay.
The value displayed corresponds to the alarm delay in minutes.
Acknowledge alarm delay set by pressing button 1. "dELA" will be displayed again.
Configuration of the GIA0420SP has now been completed. Press button 1 to switch over to the display of
the current measuring value.
