Lock Operation With I/O Module B-54900-03-3-9 - G-U B-2156 Serie Manual De Instrucciones

6.2
In addition to the control unit via the potential-free input, the motor-driven lock B-2156x/B-2157x
also offers operation with the I/O module (instruction C59501229). The control signal of the
I/O module then replaces the control signal of the lock and the door contact does not have any
function. The motor-driven lock is connected to the I/O module via an encoded bus. This connection
ensures for tamper-resistant operation. The functions of the inputs and outputs of the I/O module
are described in the following.
Connection of "control input" – control unit via potential-free contact:
A short-term release of the lock can be achieved with the control input. Per default, the latch
retracts for 5 seconds. To achieve another release, the control input must be switched again
(edge-controlled).
After applying the voltage, the lock is in service mode for 15 seconds. The blue LED on the
NOTE
latchbolt lights up. The lock only reacts to the control input after the 15 seconds have expired,
and switch the respective output signals.
Output "Lever handle" – Status via LED 1:
If a lever handle is operated, the LED lights up once for 1 second.
Output "Unlocked" – Status via LED 2:
The latch is retracted.
Output "Cylinder locking cam" – Status via LED 3:
If the cylinder locking cam sensor is crossed, the LED lights up once for 1 second.
Output "Locked" – Status via LED 4:
The latch is extended.
