ALARM inverted – fitted with jumper
(door contact, optional) Connection of CANCEL input
This input makes it possible to cancel a request for rescue if the lift is fully functional.
After pressing the ALARM button the system waits for the configured period, which is
slightly longer than the maximum period for journey of the lift. If the lift is functional,
during this period it must go to the configured station and the door must open. In such
a case the requirement is cancelled. If the door does not open, the requirement is
accepted.
Before installation find out if there is an open door signal available in the lift cabin.
Requirements :
If the lift has double doors, the signal must be active only if both sets of doors
are open, i.e., if it is truly possible to leave the cabin.
The door position signal must also work if there is a power failure.
Control by contact
Requirements :
None of the outlets from the contact may be galvanically linked with any other
electrical circuit, no voltage may be connected to the CANCEL clamps – only
contact.
Procedure
Leave the CANCEL clamp in the lower position (5).
If you use a make contact, leave the jumper as is (6 pin on jumper 12) - CANCEL
without fitting jumper (this configuration is the factory one)
If you use a break contact, fit the jumper (6 pin on jumper 12) - CANCEL
inverted – jumper fitted
Voltage control
Requirements :
direct voltage in range of 12 to 48V.
Procedure :
Move the CANCEL clamp up two pins to the position (4).
For activation by connection of voltage, leave the jumper as is (6 pin on jumper
12) - CANCEL without fitting jumper (this configuration is the factory one)
For activation by disconnection of voltage, fit jumper (6 pin on jumper 12) -
CANCEL inverted – fitted with jumper
