Chapter 5 Commission the Safety Switch
First-time Learn
Apply power to the switch without the actuator present. After the switch
completes the power-sequence (approximately 8 seconds), the status indicator
flashes green eight times, indicating the total number of times a new actuator
can be learned. This status indicator sequence repeats until an actuator is
inserted in the switch (in the guard closed position).
Perform a functional test of the switch to validate that it works as expected (see
Functional Testing on page 17
).
Learn Additional
Replacement Actuators
The switch automatically starts a new teach process when a unique coded
replacement actuator is inserted in the switch (in the guard closed position).
Lock the Actuator Code
If the actuator is removed from the switch and then reinserted into the switch
during the 15-second Program Finalization stage (see Step 4 in Table 10
), this
action 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.

(2) When teaching an actuator, the switch must be unlocked to insert the actuator. At the end of the finalization step, the switch
remains unlocked and in the safe state.

IMPORTANT After teaching a new actuator, a power cycle is required to complete the
process.
IMPORTANT When the switch learns a new actuator, it no longer recognizes previously
learned actuators.
IMPORTANT After a unique coded actuator is locked using this method, the switch cannot
learn additional replacement actuators for the remaining life of the switch. If
the actuator is lost or damaged, the switch must be replaced.
