HS5E Miniature Interlock Switches with Solenoid
Instructions
For Manual Unlocking
Spring lock
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
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.

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 operation. This is dangerous because the
interlock switch can always be unlocked while the machine is
in operation.

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.
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 53 mm, use the rear unlocking button
kit (HS9Z-FL5
∗
) sold separately.

Safety Precautions
After installing the rear unlocking button, apply Loctite to the
screw so that the screw does not become loose. The button is
made of glass-reinforced PA66 (66 nylon). The screw is made
of iron. Take the compatibility of the plastic material and Loctite
into consideration.
Installing the Rear Unlocking Button Kit
1. Install the connecting rod onto the push rod on the HS5E-L
rear unlocking button interlock switch.
2. A pin is attached to the connecting
rod. Insert the pin into the hole in the
push rod, using pliers.
3. Pull the connecting rod from the hole
in the mounting frame, and turn the
button operating pin to the horizontal

Safety Precautions
Ensure that the connecting rod is pulled out completely and
it is horizontal to the interlock switch, otherwise the unlocking
button cannot be installed.
