Technical Manual

PRECAUTIONS

READ this manual BEFORE operating or servicing this instrument. FOLLOW these

instructions carefully. SAVE this manual for future reference.

INTENDED USE

The G5 Instrument family are measuring and control devices intended for industrial

systems. Its basic function is to convert the signals from transducers to useful

information. Transducer excitation is included as well as parameter controlled signal

processing, indication of output levels, error supervision and operation of optional

external equipment. The instrument supports several types of communication

interfaces.

INSTRUMENT INSULATION AND GROUNDING

The cable connector for mains power supply should include protective grounding for

safety. The cable for 24VDC power supply (screw terminal connector) should include a

ground connected to terminal GND.

The input groups of the instrument are insulated from each other by functional

insulation. Terminals intended for connection of cable shields are connected to the

protective ground of the mains or GND terminal of 24VDC input but must not be

considered as protective grounding. Shield connection of load cell input is not

connected to mains protective ground or 24VDC GND terminal.

WARNING

Only permit qualified personnel to install and service this instrument.

Exercise care when making checks, tests and adjustments that must be

made with power on. Failing to observe these precautions can result in

bodily harm.

DO NOT allow untrained personnel to operate, clean, inspect, maintain,

service, or tamper with this instrument.

1. Introduction

General

The G5 PM Indicator is a high performance single-channel weight indicator (PM model,

panel mounted) intended for industrial systems.

The basic function is to convert the signals from strain gauge transducers to useful

weight information. Transducer excitation is included as well as parameter controlled

signal processing, indication of output levels, error supervision and operation of

optional external equipment.

As long as the error supervision detects no error, a signal called ‘In process’ is then

present but if an error is detected, ‘In process’ will be off and a specific error

message will be displayed. ‘In process’ can be set to control any digital output. Note

that there are weighing channel specific and instrument specific error detection.

All functions in the G5 Instrument are controlled by set-up parameters. Setting of

parameter values can be done from the PM front panel. Maintenance functions can be

accessed locally or remotely.

It is possible to load new software into the instrument using a SD-Card.

The instrument has 4 level supervising functions and 4 set-point functions.

Power supply

The G5-PM (panel mount indicator) is available as 24 VDC model. All input and output

signals are galvanically isolated from the power supply.

Strain gauge input

Both excitation voltage and the output signal from the transducer are measured at the

transducer to avoid influence from voltage drop in the connection cable. Excitation to the

transducer, from the G5 Instrument is provided over separate wires.

A shielded 6-wire cable must be used to connect a distant transducer to the instrument.

The analog signals from the transducer are converted to digital form and filtered to give

an internal transducer signal with high resolution.

The transducer excitation and signal values are combined to form an internal

transducer signal, representing the load on the transducer. Influenced by calibration

data, this signal is converted to a digital measurement value, the weight value, which

can be presented at the local display window and at external equipment.

Communication

The instrument utilizes the serial interface, Ethernet and a fieldbus interface for

communication with control system or computer. The serial interface consists of a RS-

485/RS-422 connection that can be used with 2- or 4-wire connection.

Weight values, level status, error status etc. can be collected and commands given

through the communication interfaces. G5 Instruments can be controlled from a master

computer or PLC using the serial interface, Ethernet interface, field bus interface or

digital I/O.

Modbus RTU protocol is used for the serial interfaces, Modbus TCP and EtherNet/IP

for the Ethernet connection. Optional fieldbus interface for Profibus, DeviceNet or

ControlNet can be used.

Technical Manual

1-2

The serial port can also be used to connect a printer for printing of weight or for

showing weight on an external display unit.

Maintenance

The G5 instrument needs no maintenance, performed by the end-user. Any service

or repair work must be performed by qualified personnel.

Contact your supplier.

Cleaning

Before cleaning the G5, disconnect the power connection to the instrument. Use a soft

cloth to clean the exterior of the instrument. For cleaning the instrument front panel, a

soft, damp, cloth may be used.

Safety information

Utilization.

The instrument may only be utilized for the measurement and control functions,

described in this Technical Manual. It is especially important to adhere to the load limits

of the input/output connectors. We accept no responsibility for any damage arising from

improper operation.

Any changes to the instrument, which causes any function changes, may only be

carried out by the manufacturer or after discussion with and permission by the

manufacturer.

If G5 is used in a manner not specified, the protection provided may be impaired.

Meaning of symbols used in this manual

Direct current.

Alternating current.

Caution, risk of danger. Documentation needs to be consulted.
