Safety Precautions

Door Hinge

HS1L

HS1L Interlock Switches with Solenoid

•In order to avoid electric shock or fire, turn power off before
installation, removal, wire connection, maintenance, or in­spection of the interlock switch.

•If relays are used in the circuit between the interlock switch
and the load, consider the danger and use safety relays,
since welded or sticking contacts of standard relays may
invalidate the functions of the interlock switch. Perform a risk
assessment and establish a safety circuit which satisfies the
requirement of the safety category.

•Do not place a PLC in the circuit between the interlock switch
and the load. Safety security can be endangered in the event
of a malfunction of the PLC.

•Do not disassemble or modify the interlock switch, otherwise
a breakdown or an accident may occur.

Instructions

•Regardless of door types, do not use the interlock switch as
a door stop. Install a mechanical door stop at the end of the
door to protect the interlock switch against excessive force.

•Make sure that no force is applied on the actuator, otherwise
the actuator may not be unlocked properly.

•Do not apply excessive shock to the interlock switch when
opening or closing the door. A shock to the interlock switch
exceeding 1,000 m/s
switch.

•If the operating atmosphere is contaminated, use a protective
cover to prevent the entry of foreign objects into the interlock
switch through the actuator entry slots. Entry of foreign ob­jects into the interlock switch may affect the mechanism of the
interlock switch and cause a breakdown.

•Plug the unused actuator entry slot using the slot plug sup­plied with the interlock switch.

•Do not store the interlock switches in a dusty, humid, or
organic-gas atmosphere, or the switches are subject to direct
sunlight.

•Use proprietary actuators only. When other actuators are
used, the interlock switch may be damaged.

•Do not modify the actuator, otherwse it will damage the inter­lock switch.

•The actuator retention force is 3000N. Do not apply a load
higher than the rated value. When a higher load is expected,
provide an additional system consisting of other interlock
switch without lock (such as the HS5D interlock switch) or a
sensor to detect door opening and stop the machine.

•Regardless of door types, do not use the interlock switch as a
door lock. Install a separate lock using a latch or other mea­sures.

•While the solenoid is energized, the interlock switch tempera­ture rises approximately 40°C above the ambient temperature
(to approximately 95°C while the ambient temperature is
55°C). To prevent burns, do not touch. If cables come into
contact with the interlock switch, use heat-resistant cables.

•Solenoid has polarity. Be sure of the correct polarity when
wiring. Do not apply overvoltage, otherwise the solenoid will
be burnt.

2

may cause damage to the interlock

•Do not install the actuator in a location where the human body
may come in contact. Otherwise injury may occur.

•Install the actuator where it does not touch human body when
the door is opened/closed. Otherwise injury may occur.

•Solenoid lock is locked when energized, and unlocked when
de-energized. When energization is interrupted due to wire
disconnection or other failures, the interlock switch may be
unlocked causing possible danger to the operators. Solenoid
lock must not be used in applications where locking is strictly
required for safety. Perform a risk assessment and determine
whether solenoid lock is appropriate.

•In order to prevent the interlock switch and actuator from
being removed without authorization, it is recommended to
install an one-way screw or a screw that needs a special tool
for removal. Welding or rivet is also recommended.

Minimum Radius of Hinged Door

When using the interlock switch for a hinged door, refer to
the minimum radius of doors shown below. For the doors with
small minimum radius, use angle adjustable actuators (HS9Z­A3S).

Note: The following values apply when the actuator does not interfere

with the interlock switch when opening and closing the door.
Because deviation or dislocation of hinged door may occur in actual
applications, make sure of the correct operation before installation.

Actuator Angle Adjustment

•Using the angle adjustment screw, the actuator angle can be
adjusted (refer to the dimensional drawing on page 87).
Adjustable angle: 0 to 20°

•The larger the adjusted angle of the actuator, the smaller
the applicable radius of the door opening. After installing the
actuator, open the door. Then adjust the actuator so that its
edge can be inserted properly into the actuator entry slot of
the interlock switch.

•After adjusting the actuator angle, apply Loctite to the adjust­ment screw so that the screw will not move.

For Manual Unlocking

Spring lock

The HS1L 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 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 opera­tion 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.

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.
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.

Conduit Port Opening

•Make an opening for wire connection by breaking one of the
conduit-port knockouts on the interlock switch housing using
a screwdriver.

•Before opening the conduit port, remove the locking ring for
cable gland inside the interlock switch.

•When breaking the conduit port, take care not to damage the
contact block or other parts inside the interlock switch. Also,
take care not to damage the internal wiring. Cut wires cause
operation failure.

•Cracks or burrs on the conduit entry may deteriorate
protection against water.

•When changing to another conduit port, close the unused
opening with an optional plug (Part No.: HS9Z-P1)

Recommended Tightening Torque

•HS1L interlock switch: 3.2 to 3.8 N·m (four M5 screws) (Note)

•Lid: 0.9 to 1.1 N·m (M4 screws)

•Terminal: 0.6 to 0.8 N·m (M3 screws)

•Cable gland: 2.7 to 3.3 N·m

•Actuators

HS9Z-A1S/A2S: 2.7 to 3.3 N·m (two M5 screws) (Note)
HS9Z-A3S: 4.5 to 5.5 N·m (two M6 screws) (Note)

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.
