For Manual Unlocking
Spring lock type
The HS5E allows manual unlocking of the actuator to pre-check proper door
movement before wiring or turning power on, as well as for emergency use such
as a power failure.
Solenoid lock type
The solenoid lock type interlock switch normally does not need the manual
unlock. However, only when the interlock switch would not release the actuator
even though the solenoid is de-energized, the interlock switch can be unlocked
manually. Unlock the interlock switch manually only when the solenoid is
de-energized. Do not unlock the interlock switch manually when the solenoid is
energized.

LOCK UNLOCK
When locking or unlocking the interlock switch manually, turn the key fully using
the manual unlock key supplied with the interlock switch.
Using the interlock switch with the key not fully turned (less than 90°) may cause
damage to the interlock switch or operation failures (when manually unlocked, the
interlock switch will keep the main circuit disconnected and the door unlocked).
Do not apply excessive force to the manual unlock, otherwise the manual unlock
will become damaged.
Do not leave the manual unlock key attached to the interlock switch during op-
eration. This is dangerous because the interlock switch can always be unlocked
while the machine is in operation.

Installing the Rear Unlocking Button
After installing the interlock switch on the panel, place the rear unlocking button
(supplied with the switch) on the push rod on the back of the interlock switch, and
fasten the button using the M3 sems screw. Rear unlocking button can be installed
alone when the total thickness of mounting frame and panel is 6 mm or less. When
the total thickness of mounting frame, panel, and mounting plate is 23 to 43 mm,
use the rear unlocking button kit (HS9Z-FL53 or HS9Z-FL54) sold separately.

Safety Precautions
Install the rear unlocking button kit in the correct direction as shown below. Do
not install the kit in incorrect directions, otherwise malfunction will be caused.
Correct Incorrect
Do not apply strong force exceeding 100 m/s2 to the interlock switch while the
rear unlocking button is not pressed, otherwise malfunction will be caused.
Manual Unlocking using the Rear Unlocking Button
The rear unlocking button is used by the operator confined in a hazardous area
for emergent escape.

How to operate
When the rear unlocking button is pressed, the interlock switch is unlocked and
the door can be opened.
To lock the interlock switch, pull back the button.
When the button remains pressed, the interlock switch cannot be locked even if
the door is closed, and the main circuit remains open.
Recommended Tightening Torque
• HS5E interlock switch: 1.8 to 2.2 N·m (four M4 screws) (Note)
• Rear unlocking button: 0.5 to 0.7 N·m
• Rear unlocking button kit: 4.8 to 5.2 N·m (M5 screw)
• Actuators
HS9Z-A51: 1.8 to 2.2 N·m (two M4 screws)
HS9Z-A52: 0.8 to 1.2 N·m (two M4 Phillips screws)
HS9Z-A51A/A52A: 1.0 to 1.5 N·m (two M4 screws)
HS9Z-A53: 4.5 to 5.5 N·m (two M6 screws)
HS9Z-A55: 1.0 to 1.5 N·m (two M4 screws)
Note: The above recommended tightening torque of the mounting screws are the values with hex socket
head bolts. When other screws are used and tightened to a smaller torque, make sure that the
screws do not become loose after mounting.
