(Note 2)

Note 1: Do not unlock manually while the solenoid is energized.

Note 2: Do not energize the solenoid for a long period of time while the door is open or while the door is unlocked

manually.

Note 3: Circuit codes XF and XG do not have signals to notify whether the switch is locked or unlocked. A different

method should be used to check the lock status.

• The contact configuration shows the status when the actuator is inserted and the switch is locked.

• Monitor Circuit: Sends monitoring signals of protective door open/closed status (door monitor) or protective door

lock/unlock status (lock monitor).

• The operation characteristics shown in the chart above are for HS9Z-A51. For other actuators, add 1.3mm.

• See page 21 for HS9Z-BA5.

• The operation characteristics show the contact status when the actuator enters the entry port of an interlock switch.
