Note: Actuator can be unlocked manually for confi rming the door
movement before wiring and energizing, and also for emergency
situation such as power failure.

The operation characteristics shown in the chart above are of the
HS9Z-A51. For other actuators, add 1.3 mm.
•
The operation characteristics show the contact status when the actuator
enters the entry slot of an interlock switch.
