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.
(Only for the type with rear unlocking button)
•
The contact configuration shows the status when the actuator is inserted and the switch is locked.
•
Main Circuit: Connected to the control circuit of machine drive part, sending interlock signals of the protective door.
•
For safety circuit input, connect to the monitor circuit.
