Operation

14. Electrical system
14.1 General
The electrical equipment operates at an operating voltage of 24 Volts. The batteries are dry batteries with
815 A current start. The Perkins diesel engine is equipped with a 3.2 kW kw starter motor.
A windscreeen wiper, horn, hour meter, fuel level indicator and two working headlights in front and on the
back are also part of the equipment.
Before commencing work on the electrical system or welding work on the machine, the battery should
be disconnected (first the negative, then the positive terminal) to prevent short circuits. To reconnectattach
first the positive then the negative terminal.
Attention: terminals should be firmly connected and not just lightly laid in. Terminals which
are not secure can cause damage to the electronics and the alternator control unit. Never
disconnect terminals while the engine is running.
Difficult starting of the engine can frequently be attributed to loose or corroded battery
terminals. These overload the life of these components.
Battery power is reduced at lower temperature.
Important: Pause for approximately two minutes each starting procedure so that the battery is
able to recover.
Proceed as follows to protect electronic devices during welding work:
1. Ignition switch to „OFF“
2. Disconnect starter battery. Battery main switch must be off.
3. Connecting the earth terminal to electronic welding devices: The earth terminal must
be connected to the part to be welded. The earth terminal must never be connected via
revolving connections. Undefined welding currents must be avoided.
4. Welding cables must not be laid parallel to electrical lines.
5. Electronic component housings and electrical lines must not come into contact with the
welding electrode.
If one of the stated actions cannot be carried out, the connector must be detached from the
electronic devices prior to welding.
In the case of plasma welding, the connectors must be detached from the CGM, the DIGSY
Compact and other electronic devices prior to welding.
