GIA 0420 VO - EX

Version: 1.0

0081

Introduction

The GIA0420VO 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 GIA0420VO 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 which are accessible after removal of the cover.
All programmable parameters of the GIA0420VO are saved in an EEProm; in case of a current failure they
will remain there for at least 10 years.The GIA0420VO 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" and values
exceeding or falling below permissible limits ensure maximum operational reliability of the device.
Prior to delivery the GIA0420VO 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".

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) Consider the contents of the EC-Type-Examination Certificate and the regulations refering the use of

electrical equipment for hazardous areas (e.g. VDE 0165).

e) When connecting a GIA0420VO 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.

f) Any changes or repair of the device is not allowed.

Please return device to manufacturer for repair or maintenance.

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.

Warning:

Do not use these product 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.

Electric connection

To connect the GIA 0420VO it is simpy plugged into an existing transmitte by means of a special adaptor
for the cubic plug according to DIN43650.

Supply voltage: device takes power directly from measuring current

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 !!

Terminal assignment (standard):

Use male plugs 1 and 2.
