Locking the Actuator Code
If the actuator is removed from the sensing field and then returned to the
sensing field during the 15-second Program Finalization stage (see Step 4 in
Table 12 ), this triggers the switch to LOCK the actuator code. This action can
be performed during any of the eight unique coded actuator learn cycles.
Error Codes during the
Commissioning Process
The following indicator patterns repeat until a Power Off/On cycle is
completed.
Prove Basic Lock Function
To prove basic lock function and to verify correct actuator alignment, it is
necessary to extend the locking bolt electronically.
These basic connections are required:
• Pin 2 (brown wire) must be connected to 24V DC
• Pin 7 (blue wire) must be connected to 0V (GND)
Power to Release
With a Power to Release switch, the locking bolt extends when the guard is
closed 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 remains in its extended position (switch locked). Use the manual
auxiliary release to unlock the switch.
IMPORTANT
After a unique coded actuator is locked using this method, no additional
replacement actuators can be learned by the switch for the remaining life of
the switch. If the actuator is lost or damaged, the switch will need to be
replaced.
Status/Diagnostic Indicator Error Code
Flashing green OSSD inputs not valid
Red-red-red-green Cannot learn a standard actuator
Red-red-red-green-green Actuator already learned
Red-red-red-green-green-green Bad RFID; actuator moved out of range
Red-red-red-green-green-green-green Exceeded learning eight actuators
Red-red-red-green-green-green-green-green Unit locked: cannot learn another actuator
IMPORTANT Do not extend the locking bolt mechanically.
Using a tool to pull the bolt out of the switch can damage or cause
misalignment of the magnet at the end of the bolt. This can cause unreliable
operation of the switch.
