5.11. GENERAL ELECTRIC SYSTEM AND BATTERY RECHARGER CHECK

The machine mounts a rectiﬁ er for the battery charge, set in the general electric frame

(box1).

This rectiﬁ er is automatically fed by the plug (both 220 V or 380 V) for the equipment

starting.

Also the diesel engine contributes to the battery charge, when it is running.

Thus, it is necessary to keep the electrolyte level in the batteries checked and keep the

positive poles greased.

We’ve seen that it is fundamental to check the safety devices correct functioning, many

of which are electric and may simulate manoeuvre mistakes.

Often, the electric plant check corresponds to the searching for a failure, given that

these parts are the most exposed to injuries due to rain, powder, vibrations etc.

The maintenance employee has to be speciﬁ cally instructed, but above all precise and

respectful of the electric parts and their connections.

We remind you some important things.

 the microswitches, the relays, the diode valves and the condensers may be similar but

connected each other in different ways. We recommend to replace them with parts

that has the same brand and the same code; try to remember the colour of the cables

or the terminal numbers not to make connections mistakes

 do not take off more than one relay at a time, check it and if necessary replace it with

an equal one

 the microswitches have a symbol representing a little arrow inside a circle or this P.

They’re just in case of emergency and cannot be replaced with other similar parts

which do not have this symbol

 Be careful with NA or NC connections

 Always re-connect the grounding cables and the equipotentiality cables

 The emergency stop buttons must be repaired immediately when a failure is

encountered.

 Follow carefully the scheme and do not operate any modiﬁ cation that may damage

or commit the entire machine functioning.

 After any intervention check all the machine emergency functions

N.B. The access to the inside of the electric plant wrappings is recommended to

be executed by instructed personnel only.
