Requirements
Maintain the LED polarity (see the cover printing).
Keep the colours: request confirmation – yellow, connection confirmation –
green.
CANCEL Connection - Door Contact, Optional
Contact Control
Connect the switch to the CANCEL terminal leaving the terminal in the lower

open. If the switch is closed when the door is closed, set parameter 916 – refer
to Programming).
Note
The LED on the PCB is not illuminated in this configuration.
Caution
The door switch or door opening signal indicates that the door is open
only if both the internal and external lift doors are open and people can
leave the cabin.
Note
To use the CANCEL input, program parameter 914 to a timeout longer
than the maximum lift running time (i.e. the time during which the door is
closed). If parameter 914 is set to 0, it is useless to set the CANCEL input
connection.
Safety
The CANCEL contact input is connected with the telephone line circuits.
Therefore, make sure that the air gap between the switch and the other
lift parts is 1.5 mm and the breakdown voltage is 1500 V at least. Make
sure that the switch contacts are not connected to any other circuits. If
these conditions cannot be met, use voltage control.
