Clean the blow-off plug at least once every 3 months to ensure that it works
properly.

Problem and solution
Before the delivery the lift is usually tested with its electric panel. Notwithstanding this, during
the first assembly there could be some inconveniences. Here to follow the main problems,
based on our experience, are indicated together with their suggested possible remedies.
HAVING VERIFIED THAT:
a) the voltage is known;
b) the power in kW is sufficient;
c) the power supply cable has a suitable cross section;
d) the control panel on/off switch is on "I" and the start push button has been pr½essed;
WHAT CAN HAPPEN IS:
PROBLEM
OPERATIONS TO PERFORM IN THEIR
PROGRESSIVE ORDER OF PROBABILITY:
REMEDY
The lift does not give any
sign
of operating.
A) Check the integrity of all the thermo-
magnetic switches.
Eliminate the cause for the
thermo-magnetic switches
tripping.
B) Verify that a phase has not been
exchanged.
Invert the phase on the supply
plug.
C) Check for wires being damaged during
loading and unloading operations.
D) Check for the
thermo
relay tripping.
Select the reset button.
E) Check that the panel transformer is not
burnt.
Replace with an equivalent
device.
F) Check for the motor group’s limit stop and -
at the same time- for two phases inverted.
Remove the slides from the
base temporarily to test the lift
G) Check that due to vibrations in the
connector block of the motor group no wire is
disconnected
or unfastened.
Reestablish
the contact.
The motor is noisy and it
is not strong enough for
the lifting.
A) Make sure that the lift has not been
overloaded.
Remove the
reason
and follow
the load rules.
B) Check for the lacking of a supply phase.
Verify the cause and take
action (thermo-magnetic
switches, cable cut, error of
connection).
C) Check that brake is not burnt or wet
Replace the solenoid and/or
the pad, adjust the air gap
between the armature and the
field magnets-.
D) Emergency brake activated
Verify what the causes are and
after the resetting of the safety
conditions reset it.
By
pressing
the
rise/descent push-button
the elevator does not
move but a hum emitted
by the electric motors is
heard
A) Poor voltage
A) Increase power at the
source.
B) Two-phases supply instead of three
B) Verify the electric connection
