Initial position: Lift outside of the doorzone
K10 and K11 dropped-out, K12 tightened.
Lift runs in door zone: B178 and B179 get closed successive or simultaneous.

completed.
R12 and C12 delay the depression of K12 for max. 100ms, in order to make
lock K11 possible.
Lift is leaving door zone: B178 and B179 opens, K10 and K11 depresses, K12 activate.

EMERGENCY STOP
According to EN81 14.1.1 one single error do not lead to a dangerous operating conditon and will be
recognized, as the lift will make an emergency stop by disconnecting the security circuit while opening the
door within a door zone. In addition there is existing a further monitoring done by the controller.
Dependent up on the re-levelling sensors, which are independent from the door zone sensors, K14 is
activated.
In the unlikely case, that both door-zone-sensors by leaving the door zone would be hot-wired, a by-pass outside
of the door zone will be avoided by the circuit via K14.
Additional Monitoring by control
The controller is monitoring via K10, K11, and K12 the security circuit. During the journey the contact chain have
to be closed once inside the door zone and have to be opend once outside the door zone. In case of an error, the
installation will be shut down at the next stop with error message. Part of encoder
Scan control at the security circuit
On the board SM01 F5021 there are 4 inputs for 230V. These are installed according to the requirements of
EN81 at scan controls for security circuits. This is confirmed by TÜV with a confirmation assessment.
Basically the circuit consist of pre-resistors, protection diodes and optocoupler with VDE-approbation.
