The direction dependency of the inspection limit switches means, that it is possible to drive the car into the safe
direction with the inspection pod even after OC has opened due to over -travelling of the inspection limit switch.
Therefore, a man e.g. on the roof is no trapped, but he can release himself by moving the car downwards.
13.2.6.9 Check on correct travel direction in inspection
LIMAX33 CP-00 supervises also the consistency of direction button and real moving direction:
 If the UP Button is pushed and the car travels DOWN, OC will open

If the DOWN Button is pushed and the car travels UP, OC will open
The roll-back (at start of movement) effect is taken into account.
If OC opened due to a contradiction of direction button state and real movement, they will close again after
stand still and both buttons released. The connections of LIMAX33 CP-00 with the inspection panel should be
checked in this case.
13.2.7 Safety function „Working Platform“
LIMAX33 CP-00 fulfills the safety functions “working platform” in order to prevent a movement of the car under
all conditions.

Safety concerning “Working Platform” is activated if the “Working Platform”-signal (input) is active.

An open input “Working Platform” or Low-level means “active”, 24 V on the input means “not active”.

In case safety concerning “Working Platform” is activated, all actuators will open.

They will close again if input “Working Platform” is deactivated (24 V on the input).
NOTE!
If this functionality is used in conjunction with safety gear which does not reset itself, there is a
danger that the technician will lock himself in using this function (for example, on the roof of
the car above the uppermost floor). Electronically triggered safety gears often have the char-
acteristic, for example, that they do not reset themselves when the voltage returns, even if they
have triggered at standstill.
