Probable causes
1.1. The motor or engine is not being powered.
1.2. The selector switch is in the OFF position.
1.3. The automatic monitoring devices for motor
failure will not allow the unit to start.
2.1. Fuses of an inadequate size.
2.2. Insufficient electrical insulation.
2.3. Broken power cable.
2.4. The powering voltage rating fails to correspond
to that of the motor.
3.1. Full voltage is not reaching all motor phases.
3.2. The power draw is unbalanced on the phases.
3.3. Abnormal power draw.
3.4. Wrong relay setting.
3.5. The rotor of the unit has locked.
3.6. The power rating fails to correspond to that of
the motor.
4.1. Wrong relay setting.
4.2. Mains voltage too low.
4.3. Unbalanced power draw on the phases.
4.4. Abnormal power draw.
4.5. Electric panel temperature high.
4.6. Motor turns in the wrong direction.
Remedies
1.1. Make sure that there is fuel.
Make sure that the electrical equipment is in
a good condition.
Make sure that the unit is being powered by
the electricity main.
1.2. Select the ON position.
1.3. Wait until conditions have returned to normal
or make sure that the automatic devices have

supply.
3.1. Make sure that the electrical equipment is in
a good condition.
Make sure that the terminals are correctly
tightened.
Check the power rating.
3.2. Check the phases for unbalance as described
in paragraph 5.5 "Electrical connections and
information".
Overhaul or replace the electric motor if
necessary.
3.3. Make sure that the star or delta connection is
correct.
Check the operating flow rate. If excessive,
reduce it by means of the sluice valve on the
delivery duct.

3.5. Disconnect the power source and attempt to
release the rotor by hand.
Send the unit to an authorized after-sales
service center if necessary.
3.6. Replace the electric motor or check the
power rating.
4.1. See 3.4.
4.2. Check for losses from the power main.
Contact the Electricity Board if necessary.
4.3. See 3.2.
4.4. See 3.3.
4.5. Make sure that the relay is at compensated
ambient temperature.
Protect the electric control panel from the sun
and heat.
