Checking the adjustment of the wire rope safety switch
With the unladen platform raised and suspended on the wire ropes, check at each cross-member end that
there is a clearance of approx. 0 to 0.5 mm between the switch roller and the cam that is part of the sensor.
If necessary, adjust the position of the switch in order to obtain this clearance (Fig. 12).
Checking the obstruction/wire rope failure sensor
• Place an obstruction under one end of a cross-member.
• Lower the platform until the latches fall back against the ladders and the lift stops.
• Check that it is no longer possible to operate the RAISE control. If necessary, check the switch
position and electrical circuit.
• In order to free the obstruction, raise the sensing roller, then whilst keeping it raised, rotate the
control knob towards RAISE, until this obstruction can be removed.
• Repeat this sequence for all of the cross-member ends.
Checking the ladder latching
With the unloaded platform raised and suspended on the wire ropes, check each cross-member end as
follows:
• Disconnect one conductor from the latch solenoid and then start to lower the platform until the
latches fall back against the ladders and the platform is stopped. The latter must occur before
there is a 100 mm maximum offset between the heights of the cross-member ends. Ensure that
this is correct and check that the ‘RAISE’ command is still possible.
If the results of one of these tests are not satisfactory, bring the platform back to level, suspended on the wire
ropes and then check the 6 mm clearance of the retaining rod (see Fig. 17), as well as the switch position
and electrical circuit.
Reconnect the solenoid and then check another end.
