4.10.3 ADJUSTMENT OF TROLLEY
MOTORS BRAKE - MOTORS WITH
CYLINDRICAL ROTOR
This step must be performed with a still trolley and
without load.
If the braking distance is longer then necessary,
increase the brake torque as follow: loosen the screw
pos. 1, remove the cover, pos. 2, loosen the screw
pos. 3 and loosen or tighten the nut pos. 4 in order to
adjust the brake opening.
NB: turning the nut clockwise the brake distance
decreases and vice versa. The brake opening shall
have a range between a minimum of 0.5 mm up to a
maximum of 0.8 mm. This value can be checked by
putting a thickness meter between pos. 5 and 6.
4.10.4 ELECTROMECHIANICAL LOAD
LIMITER SETTING
1st threshold warning
Apply the rated load, switch-on the hoist motor and
check proper intervention, with the signal on the button
panel or the siren if available.
2nd threshold warning
The 2nd threshold must stop all movements (except
going down).
Apply a load 15% higher than rated load, switch-on
the hoist motor and check the proper intervention.
Note - The dynamometric or electromechanical
load limiter is statically pre-set by the manufacturer.
Should it not work properly, perform its settings as
explained in the chapter settings - paragraph 4 on
page 55.

4.10.5 DYNAMOMETRIC LOAD
LIMITER SETTING
Any calibration of the limiter with rated load for the
1st threshold with dynamic load +10% and the 2nd
threshold with static load +25% of the rated load must
be carried out by a specialist technician following the
procedure described with a sample weight.
If the system is not working properly, refer to
the “Installation and Use Manual” of the limiter
with relevant electronic board attached to this
documentation.
