LIFT MODEL VISION AS 300 Rev001
7-8
Before power is connected to the hoist
MAKE SURE
that:
•
no wire is broken and that all the guards have been mounted;
•
the descent limit switch slide is properly mounted;
•
the feeding cable is free to move;
•
t
he earth connection is functioning (R lower than 2ohm)
•
all the switches inside the panel are activated.
CHECK
also:
•
ajusting o
f the switches of the motors, according to the motors rating-plate data.
•
ajusting of the motor brakes switch, 6 A approx.

Preliminary checks
ATTENTION:
During the mounting (and dismantling) operations of the mast, two
authorized persons must always be present, provided with safety
helmet, safety boots, protective gloves and quick fastening safety
harness on. The harness should be hitched to a supporting rode
descending from the summit of the building.
•
Check that all the switches inside the panel are activated. Check the calibration of
the motor switch according to the motor rating-plate data, check the calibration of
the switch of the motor brake, 1 A approx. Press the resetting buttons of the two
switches.
•
Connect power to the cable and the control panel by operating the main switch.
Verify that the emergency push-button has not been pressed. Unlock it in case, by
turning one fourth turn. Test the switching of the lamp -which lightens the cabin and
the acoustic alarm.
•
Operate the push-button panel. As a test, carry out a maneuver of descent in order
to make sure that the
cabin
does not collide with the base pads. If the
cabin
rises
instead of descending, invert two phases of power supply so as to invert the
direction of motion; this way, the proper correspondence of push-buttons with
movement is determined. Make sure of the descent limit switch working order.
•
Move the cabin to a position suitable for the insertion of another trestle.
•
Verify the
adjustment
of the control unit inside the control panel. This unit is to be
calibrated by adjusting the duration of time from the moment the descent button is
pressed -and therefore the brake opens- to the moment when the intervention of the
electric motors is required. This adjustment must be carried out so as to prevent the
motor from receiving shocks. Anyway, durations of time too long must be avoided
(longer than two seconds) otherwise the emergency brake gets activated and the
cabin
blocked.
•
The crane tower must be able to transfer the load.
•
Make sure that the admittances to the floors are adequately fenced.
•
Warning signs, applied inside the hoist way, to avoid the possibility of falling into the
hoist way.
