IN CASE OF FAILURE #5 CHECK IF THE
ROTATION OF THE MOTOR IS CORRECT AS
FIRST.
TO CONTROL THE MOTOR WHEN IT DOES
NOT RUN:
 Disconnect power supply.
 Remove the motor terminals cover.
 Select the multimeter in Ohm and check if
there is continuity between terminals U, V and
W of the motor (Fig.69).
Fig.69
TO CONTROL THE MOTOR WHEN IT IS
NOISY:
 Disconnect power supply.
 Remove the motor fan protection and check if
the fan is well tightened.
 Mount the motor fan protection.
 Remove the motor terminal cover (Fig.69) and
verify if all wires are well fitted on terminals.
 If the wires are well fitted on terminals mount
the motor terminals cover and remove the 4
motor screws very carefully: the motor may
fall down suddenly.
 Place the motor on the frame as shown in
Fig.71.
 Switch the motor on and listen it: if it is noisy
replace it by following the next step.
TO CONTROL THE MOTOR WHEN THE
CIRCUIT BREAKER SHUTS OFF.
IMPORTANT!
BEFORE STARTING WITH ANY CONTROL
AND REPLACEMENT VERIFY IF THE
BREAKER IS CORRECTLY REGULATED
COMPARED TO MOTOR DATAS.
 Disconnect power supply.
 Remove the motor terminal cover (Fig.69) and
verify if all wires are well fitted on terminals.
 If the wires are well fitted on terminals take
the ammeter pliers.
 Regulate the scale according to the maximum
amperage reported on the motor.
 Connect the pliers to a wire (Fig.70).

MACHINE UNDER TENSION
DANGER OF ELECTRIC SHOCK
 Switch the machine on.
 Make a hydraulic movement and get the
pump under pressure.
 Press the button to lock the value reported by
the pliers.
 Perform the above control on all wires.
 If the amperage required by one or more
phases is 10% higher compared that one
reported on the motor tag, increase the
breaker adjustment.
 If the amperage is higher than 10%, the motor
must be replaced.
TO REPLACE THE MOTOR:
 Remove all wires from the motor.
 Remove the 4 motor screws very carefully:
the motor may fall down suddenly.
 Remove the aluminium spacer.
 Take the distance of joint compared to the
motor by using a calliper (Fig.71).
