For Manual Unlocking
Spring lock
The HS1L 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
The solenoid lock 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.
Using manual unlock key
•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 opera-
tion failures. When manually unlocked, the interlock switch will
keep the main circuit disconnected and the door unlocked.
Main circuit and lock monitor circuit remain open.
•Do not leave the manual unlock key attached to the interlock
switch during operation. This is dangerous and does not
satisfy the requirement by safety standards, because the
interlock switch can always be unlocked while the machine is
in operation.

Unlocking from the back of interlock switch
Insert the tip of a small screwdriver into the oblong hole on the
back of the interlock switch, and tilt toward the center of the
switch until the actuator is unlocked.
Note: Provide a hole on the mounting panel for unlocking from
the back. When making a hole in the panel, take water-
proof characteristics into consideration.

Safety Precautions
Before manually unlocking the interlock switch, make sure that
the machine has come to a complete stop. Manual unlocking
during operation may unlock the interlock switch before the
machine stops, and the function of interlock switch with sole-
noid is lost.
On the solenoid lock, manual unlocking is provided for the
situation where the switch cannot be unlocked even though the
solenoid has turned off. Do not attempt manual unlocking while
the solenoid is energized.
Precautions for Opening and Closing the Lid
•When opening the lid before wiring, make sure to open only
the lid shown the following figure. Removing unnecessary
screws may cause a failure of the interlock switch.
•Use HS9Z-T1 key wrench for TORX screw when removing
and installing the lid.
•Make sure that no foreign objects such as dust, water, or oil
enter the interlock switch when wiring.
