E15.0.01.6C-05 GIA0420 / GIA0420 SP Connection and operating manual page: 1
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.
The measuring value is displayed on a 4-digit LCD display with the max. display area ranging from -1999 to +9999 digits.
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
In order to exclude any risk whatsoever for the operator the following points have to be observed:
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.
