1. Safety regulations

This device was designed and tested considering the safety regulations for electronic measuring devices.
Faultless operation and reliability in operation of the measuring device can only be assured if the General

Safety Measures and the devices specific safety regulations mentioned in this users manual are considered.

1. Faultless operation and reliability in operation of the measuring device can only be assured if the device
is used within the climatic conditions specified in the chapter “Specifications“

2. Always disconnect the device from its supply before opening it. Take care that nobody can touch any of
the unit‘s contacts after installing the device.

3. Standard regulations for operation and safety for electrical, light and heavy current equipment have to be
observed, with particular attention paid to the national safety regulations (e.g. VDE 0100).

4. When connecting the device to other devices (e.g. the PC) the interconnection has to be designed most
thoroughly, as internal connections in third-party devices (e.g. connection of ground with protective earth)
may lead to undesired voltage potentials.

5. The device must be switched off and must be marked against using again, in case of obvious malfunc­tions of the device which are e.g.:

- visible damage.

- the device is not working as prescribed.

- storing the device under inappropriate conditions for longer time.

When not sure, the device should be sent to the manufacturer for repairing or servicing.

ATTENTION: When running electric devices, parts of them will always be electrically
live. 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 and maintenance.

SKILLED PERSONNEL

Are persons familiar with installation, connection, commissioning and operation of the product and have
professional qualification relating to their job.

For example:

• Training or instruction and qualifications 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.

ATTENTION:

Do NOT use this product as safety or emergency stopping device, 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.

2. Introduction

The GIA 20 EB / PK is a microprocessor controlled displaying, monitoring
and controlling device.

The device is supporting one universal interface for the connection of:

- Standard transmitter signals (0-20mA, 4-20mA, 0-50mV, 0-1V,

0-2V and 0-10V )

- Resistance sensors

- Frequency (TTL and switching contact)

The device features two switching outputs, which can be configured as
2-point-controller, 3-point-controller, 2-point-controller with min./max. alarm,
common or individual min./max. alarm.

The state of the switching outputs is displayed with two LED’s beneath the
front 4-digit LED-display.

The left LED displays the state of the 1st output, the right LED displays the state of the 2nd output.
Furthermore the device supports one EASBus-interface so that the device can communicate with a host

computer via an interface converter and makes the device to a full functions EASBus-module.
When leaving our factory the GIA20EB / PK has been subjected to various inspection tests and is completely

calibrated.

Before the GIA20EB / PK can be used, it has to be configured for the customer’s applica­tion.

Hint: In order to avoid undefined input states and unwanted or wrong switching processes, we sug-

gest to connect the device’s switching outputs after You have configured the device properly.

For configuring the GIA20EB please proceed as follows:

- Disassemble the red front plate (see sketch).

- Connect the device to its supply
(see chapter 3 ‘Electric connection‘).

- Switch on the supply voltage and wait until the device completed its
built-in segment test .

- Adjust the device to the input signal required. Follow the instructions
in chapter 4 ‘Input configuration‘

- Follow the instructions given in chapter 5 ‘Output and alarm
configuration‘ to configure the outputs of the GIA20EB.

- Reassemble the red front plate.

- Connect the device properly (see chapter 3 'Electric connection‘)

3. Electric connection

Wiring and commissioning of the device must be carried out by skilled personnel only.

In case of wrong wiring the device may be destroyed. We can not assume any warranty in case of
wrong wiring of the device.
