Omron A22LK Series Manual page 3

Locking the A22LK-2RLA-@ in the MAINTENANCE Position
Maintenance is performed without stopping the facilities after the door switch is temporarily disabled. If the mode is
changed to RUN mode while the door is open, the door switch will be enabled and the facilities will be stopped.
Locking the A22LK-2RLA-@ in the MAINTENANCE position prevents the mode from being changed unintentionally.
