automatic lift operation. Moving the car and the door is only possible
by activating the command buttons of the inspection control unit
(dead man's circuit) in absence of the emergency control functions
(either switched off or not installed). In addition, activation of a stop
button, which can only be returned to its original position by turning it,
can cause an emergency stop. The limit switches prevent the car
from over-travelling the terminal landings.
INFO!
Switching on the inspection control overrides the emergency control
(see DIN EN 81, part 1 , 14.2.1.3 and 14.2.1.4)
If the control unit is made by BÖHNKE + PARTNER GmbH, prefer-
ence is also given to the inspection control when the car or door can-
not be moved any more, with the inspection control turned on and the
emergency control switched in and vice versa.
Switching the inspection control deletes all existing calls and disables
the push buttons for cabin calls, landing calls and superior control
functions.
All safety circuit devices remain effective (DIN EN 81 part 1,
14.2.1.3).
Once the lift system is switched back to normal operation, you can
make a call to trigger correction travel for the landing counter. Control
units equipped with an absolute encoder do not require a correction
travel.
