CANCEL Input Connection (Door Control, Optional)
Caution
 The door switch or door opening signal must indicate an open door only if
both the internal and external lift doors are open and the lift car can be
left safely.
Note
 If the CANCEL input is used, be sure to program parameter 914 for a
period longer than the maximum lift running time (i.e. while the door is
closed). If parameter 914 is set at 0, it is useless to connect the CANCEL
input.
Switch control
Safety
 The CANCEL input is connected with the telephone line circuits. Therefore,
the air distance between the switch and the other lift parts must be 1.5
mm at least and the break-down voltage may not be less than 1500V. The
switch contacts may not be connected to any other circuits. In case the
above mentioned conditions cannot be met, use the voltage control.
 Connect the switch to the CANCEL terminal, leaving it in the low position.
 By default, the ST is set for a switch that is closed when the door is open. If
the switch is closed when the door is closed, select parameter 916 – see
Programming.
Voltage control
DC voltage of any polarity ranging between 12 and 24V can be applied.
 Slide the CANCEL terminal out and switch it in the upper position to ensure
the required isolation against the telephone line circuits.
 In the event of voltage disconnection activation select parameter 916 – see
Programming.
 By default, the ST is ready to accept a sensor that applies voltage when the
door is open. If it gives voltage when the door is closed, select parameter 916 –
see Programming.
Caution
 If voltage presence indicates that the door is closed, this source must be
backed-up against power outage.
