Series-65H Hoist Pos 4
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 (H2) in the cage is switched on.
Part of the safety circuit is shown in the pic-
ture beside. The complete safety circuit
can be found in electrical diagrams.
