HS5L Interlock Switches with Solenoid
Instructions
Adjustment
Adjustment Procedure
1. Make a hole at A or C.
2. Fasten temporarily with screws, and check the actuator
position.
3. Make a hole at B and x the actuator using a screw or a rivet.
• 3.3mm line
The mounting reference position is where the door is fully closed,
and there is a 0.8mm space between the safety switch and
HS9Z-BA5, but can be adjusted up to the 3.3mm line.
The actuator is most securely locked when the mounting
reference position is at the 0.8mm line. However, adjust between
0.8 to 3.3mm if the interlock switch is mounted on a door where
the space might become smaller.
• Lock limit line
When a door opens by bouncing, if the lock limit line is outside
of the edge of the interlock switch, the force of the bounce may
be too large so that the door may not lock.

Safety Precautions
• The maximum gap of the door that can be locked is 16mm.
(When mounting reference is a the 0.8mm line)
• If the safety distance and minimum gap does not satisfy the
requirements of ISO13857, make the gap smaller by overlapping
the doors or by providing sufcient distance from the hazardous
source. If the required safety distance cannot be obtained, use
the actuator other than spring loaded actuator.
• The operating characteristics may change when the actuator is
used with the HS5L. Check the operating characteristics before
use.

Manual Unlocking
Spring lock
The spring lock interlock switch allows manual unlocking of the
actuator to precheck proper door movement before wiring or
turning power on, as well as for emergency use such as a power
failure.
Solenoid lock
The solenoid interlock switch does not unlock even when the
solenoid is de-energized. However, the interlock switch can be
unlocked manually in emergency cases.

LOCK
When locking or unlocking the interlock switch manually, turn the
key fully using the manual unlock key supplied with the interlock
switch as shown above. 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 solenoid is lost.
Installing the Rear Unlocking Button
(HS5L-L)
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 M3 sems
screw (supplied with the switch).

When installing on a mounting frame

Safety Precautions
After installing the rear unlocking button, apply Loctite to the
screw so that the screw does not become loose. The rod is made
of stainless steel, the button is made of glass-reinforced PA66 (66
nylon) and the screw is made of iron. Take the compatibility of the
plastic material and Loctite into consideration.
