CANCEL Input Connection (Door Contact, Optional)
This input helps cancel a rescue request if the lift is fully functional. When the ALARM
button is pressed, the system waits for a pre-programmed period of time, which is a
little longer than the maximum lift running time. If the lift is functional, it arrives in the
required station within this timeout and opens the door. In that case, the rescue
request is cancelled. If the door does not open, the request is accepted.
Find out before installation whether the door opening signal is available in the lift cabin.
Requirements
If the lift has a double door, the signal must be active only if both the door sets
are open, i.e., if it is really possible to leave the cabin.
The door position signal has to work even in the case of power outage.
Contact control
Requirements
None of the contact outlets terminals may be connected electrically with any
other electrical circuit and no voltage source other than the NO/NC contact may
be connected to the CANCEL terminals.
