Lift Cabin Audio Unit

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.
Find out before installation whether the door opening 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.
Keep the CANCEL terminal in the LOW position (5).
2.
With a normally open contact, leave jumper (12) – left in the default position.
3.
With a normally closed contact, switch jumper (12) – left into the LOW
position.
Voltage control
Requirements
DC 12 to 48V voltage
Instructions
1.
Switch the CANCEL terminal by two pins up into position (4).
2.
For activation by voltage connection, leave jumper (12) – left in the default
position.
3.
For activation by voltage disconnection, switch jumper (12) – left into the LOW
position.
Warning
Ignoring the instructions above may lead to product damage.
Note
Remember to program delayed calling to make the CANCEL connection
work successfully.
