2) lf pressing the pedal contactor makes connection, but the M electric motor does
not start. There should be two situations
a. lf M motor is correctly.-check if the electric motor is in order: stator winding not
to be broken, connections at the terminal box to be perfect etc.
b.If M motor is not correctly fed from, check motor force circuit:
.Attention: Use only calibrated replacing pieces and at the parameters indicated
-check if electric stress circuit of the FR thermal relay is not broken.
-check all junction wires and cable of electric stress circuit not to be broken.
All necessary checks can be made with a general instrument (multi-meter) which
measures: V, A, Ω.
2. Maintenance operations : Weekly checking:
-make visual checking of electric apparata condition and in case they are
damaged will be replaced with others at the same parameters;
-tighten the screws of electric connections and the holdings screws of electric
apparata;
-check condition of feeder cable, jack and connection socket to the mains and in
case they are damaged will be replaced with others at the same parameters;
-check if earthing circuit has continuity and its ohmic resistance;
-wipe the dust on the electric apparata and connecting elements. Cleaning can be
made with an air jet of maximum 2 atm. or with a brush
F. Labor protection rules
Respect all instructions and norms in force when mount, put into service, repair
and maintain the electric installation.
Stop the machine and release it from the mains before any intervention to the
electric installation to before periodical checking of electric equipment and motor.
All operations which ask the electric installation under voltage (measuring the
energy, voltage, determining succession of phases) will be effected only by skilled
people with legal authority. They must have proper tools equipped with
non-conducting handles and non-conductive protection equipment.
It is forbidden by any modification of the electric installation if it is certificated by
the manufacturer. lt could be dangerous.
