•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).

•For safety circuit input, connect to the monitor circuit with

marking.

Note 1: Actuator can be unlocked manually for confirming

the door movement before wiring and energizing,

and also for emergency situation such as power

failure.

Note 2: When the operator is confined in a hazardous zone,

the actuator can be unlocked manually by pressing

the rear unlocking button.

•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.
