Very often checking the electrical system coincides with the search for a fault, as these
components are the part most exposed to damage due to rain, dust, vibrations, etc.
The maintenance technician / mechanic must be particularly prepared but above all
precise and respectful of the electrical components and their connections.
Let’s remember a few things:
x
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 coloured of the
cables or the terminal numbers not to make connections mistakes
x
do not take off more than one relay at a time, check it and if necessary replace it with
an equal one
x
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 these symbol
x
Be careful with NA or NC connections
x
Always re-connect the grounding cables and the equipotentiality cables
x
The emergency stop buttons must be repaired immediately when a failure is
encountered.
x
Follow carefully the scheme and do not operate any modifi cation that may damage
or affect the entire machine functioning.
x
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.
