If the hoist control system seems dead check the hoist’s supply voltage.
•
Check that the main switch (Q1) in the
ground station electric control box is
switched on to position 1.
•
Check that the residual current breaker
FI05 in the ground station control cen-
tre is switched on.
•
Check that the main switch (Q2) on the
roof control box is switched on to posi-
tion 1.
•
Check that the possible cable plugs
supplying the hoist are properly con-
nected.
•
Check that the switch gear on the site’s
switchboard or other switchboard is
switched on.
All electrical installations are al-
lowed to be carried out only by
a qualified professional in elec

The hoist’s safety circuit consists of forced
limit switches, emergency stop buttons etc.
which in series form the control circuit. This
circuit controls the safety relay and two se-
ries-connected main contactors, through
which the voltage is supplied to the en-
gines. So if for instance the emergency stop
button is pushed down the safety circuit is
disconnected. In this case also the voltage
supply for the engines is disconnected and
the hoist cage stops its movement or does
not start if it is standing at the moment.
When the safety circuit is connected, the
pilot lamp (H66) in the cage is switched on.
The complete safety circuit can be found
in electrical diagrams.
