Codes During the Learning
Process The following code sequences persist until a Power On/Off cycle is
completed.
Proving Basic Lock Function To prove basic lock function and to verify correct actuator alignment, it
may be necessary to extend the locking bolt. The locking bolt cannot be
extended by mechanical means; you must proceed electrically. The
following basic connections are required:
• Pin 2 (brown wire) must be connected to 24V DC
• Pin 7 (blue wire) must be connected to 0V (GND)
In the case of a power-to-release switch, the locking bolt will extend
when the guard is shut and the actuator is aligned. Connect Pin 3 (green
wire) to 24V DC to unlock the switch and withdraw the locking bolt.
If power is removed from a power-to-release switch in the locked
position, the locking bolt will remain in its extended position (switch
locked). Use the manual auxiliary release to unlock the switch.
In the case of a power-to-lock switch, connect Pin 3 (green wire) to 24V
DC to lock the switch (i.e. extend the locking bolt). Disconnecting Pin 3
will unlock the switch.
If power is removed from a power-to-lock switch in the locked position,
the switch unlocks.
In either type of lock, the locking bolt never extends in the absence of the
actuator.
