he accepts eventually incomplete operation manuals. The information described is without guarantee. Errors and changes

are reserved.

Intended Purpose, Improper Usage

A device is used for displaying, processing and controlling or regulation of processes. It shall not be used as the only tool for

the prevention of dangerous states to machines and plants. Machines and plants must be constructed in such a way, that

erroneous states can not lead to a dangerous situation for the staff (e.g. by independent limit switches, mechanical locking

devices). It must be guaranteed in particular that device-operating errors, its malfunction or it’s breakdown do not lead to

great property damages or danger for the staff. Consequently, the device then can be used to prevent the machine or the

technical installations from error conditions.

It is also important that the use of devices does not endanger precautions for the safety of technical installations.

Emergency-off settings must remain effective in all operation modes.

Installation Notes

The devices must be installed and connected by compliance with the relevant DIN- and VDE-norms. They must be installed

in such manner that an unintentional use is sufficingly excluded. The corresponding hardware and software safety

precautions are to be observed in such manner that an interruption of the supply and signal cables cannot lead to an

undefined or dangerous state. Supply and signal cables must be installed in such way, that disturbing signals (e.g. inductive

or capacitive intersperses) will not cause derogations to the function of devices.

Disturbance, Maintenance and Repair Notes

The devices do not contain parts which can be maintained on the customer side. Repairs shall be carried out by exclusively.

If assuming that a safe operation of the device is not possible anymore, it must be closed down and protected against

unintentional handling immediately. This, in particular, applies:

If the device shows visible damages

If the device is no longer operative

If parts of the device are loose or slack

If the connection cables show visible damages

Furthermore, we point out that all obligations of exclusively result from the respective sales contract in which the

guarantee has been conclusively settled.

GM 80 TG/PA Brief Handling Overview

Mains Operation:

GM80 TG: Wall power supply with 24V DC / 250mA is part of the delivery scope.

GM80 PA: The supply voltage of 16-30V DC is connected via a BMS-plug.

Battery for Date and Time:

A commercial CR2032 lithium battery with 3V is used. If time and date continuously begins at 0.00 hrs and date of

01.01.70, the battery must be exchanged. Switch the GM80 off-circuit first!!! At the GM80-TG both screws are

unfixed at the bottom and the housing top has to be removed.

At the GM80-PA the front framework is removed and the front foil has to be slightly lifted at all 4 corners, then the

underlying screws need to be unfixed. Then the circuit board can be pulled out carefully. The battery is located on

a clamp on the circuit board and can easily be exchanged. “Plus” on top!

Control inputs: Trigger, Enable, Tare/GWS2

This input can be controlled e.g. with a PLC, remote switch, foot switch... or similar.

It is an optocoupler input and therefore it is separated galvanically.

As a control signal, 0V - 2V is recognized as low level, 3,5V -27V as high level.

Trigger:

Thus depending on the adjustment, data can be stored or interface data can be issued.

This input has a high sampling rate, therefore very short impulses are recognized as well.

Enable:

By this the min. and max. value is deleted externally.

In the display mode Max or Min, e.g. after each measurement the min. or max value can be deleted in order to acquire the

next min. or max. value.

Tare / GWS2 (limit value set 2):

Select in the menu which function should be carried out while applying a signal.

Tare: tare externally.

GWS2: by this the second limit value set is being activated, parameters are being adjusted in the menu.

Operation Mode Low level High level

GWS1 + TARE GWS1 TARE

GWS1 + GWS2 GWS1 GWS2

Serial Interface Adjustment:

Parity: none

Data bits: 8

Stop bits: 1

Limit Values:

2 switching points (SP), independent from each other, can be configured in value and the switching direction. The second

limit value set has to be activated by the control input.
