II. Connections
1.
Connecting load cell to indicator
User can connect any load cell, which have output voltage in range 1÷3 mV/V.
Usually a load platform is build, laying on such sensors.
This electronic indicator works by 4-wire connection scheme. If the sensor/sensors
are with 6 wires it must be set to 4-wire connection – user must shorten (connect
together) signals
Se+
with
Ex+
and
Se-
with
Ex-
.
Generally sensors have following wires and signs:
Ex+
- positive supply voltage for load cell (Exc);
Ex-
- negative supply voltage for load cell (Excitation-);
-

Load cell plug in G5102 is Canon DB9 type, female. Correct pin connection is as
follows:

2.
Connecting power supply
Every G5102 comes with power supply cable for 220V AC, suited for indicator.
From the one side this cable should be plugged in G5102 (connector 6 from I. General
description), from the other – in power supply network. It can not be plugged wrong.
Cable is a two-pole – phase and zero. Since indicator has a plastic enclosure – grounding
is not necessary.
As an option G5102 can be offered to work on DC voltage with external adapter or
accumulator, but this can be specially noted when ordered.
Above power cable is placed safety fuse. If scale indicator is not working at all (i.e.
– display is not showing anything) most probably the fuse is gone and must be replaced
with proper one. For information about fuse and its change refer to p.

Turning on G5102, initial checking
Turning on G5102 is simply plug power cable to power supply network 220VAC. If
everything with G5102 is in order it will start working.
