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 fails to open, the request is accepted.
Make sure before installation that the “door open” signal is available in the lift cabin.
Requirements
 In double-door lifts, the signal has to be active only if both the doors open
successfully and let the people out.
 The door position signal has to work even in the case of power outage.
Contact control
Requirements
 None of the CANCEL terminals may be connected electrically with any other
electrical circuit and a voltage source other than the contact.
Instructions
1. Connect the CANCEL terminal into upper position.
2. Make sure that the switch position matches the door contact configuration
(open or closed when the door is closed) – see Address setting.
Voltage control
Requirements
 DC 12 to 48V voltage
Instructions
1. Connect the CANCEL terminal into lower position.
2. Make sure that the switch matches voltage presence or absence when the door
is closed – see Address Setting. Voltage presence corresponds to a closed
contact; voltage absence means an open contact.
Warning
 Ignoring the instructions above may lead to product damage.
Note
 Remember to program delayed calling to make the CANCEL connection
work successfully.
