Head Removal Detection Circuitry

Head removal detection circuitry is employed in the HS5L. With this innovative
function, the monitor circuit (41-42) turns off when the head is removed from
the switch, such as when removing the head to change the head direction
(applicable with the HS5L spring lock models). For example, for circuit codes:
VB, VD and DD, which have two or more lock monitor circuits installed,
removing the head results in disparity (41-42: OFF, 51-52: ON).
This disparity is detected by the head removal detection function.

Safety Precautions

HS5L Interlock Switches with Solenoid

• In order to avoid electric shock or re, turn power off before
installation, removal, wiring, maintenance, or inspection of the
interlock switch.

• If relays are used in the circuit between the interlock switch
and the load, use only safety relays, since welded or sticking
contacts of standard relays may invalidate the functions of the
interlock switch. Perform a risk assessment and make a safety
circuit which satises the requirements 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
malfunction or an accident may occur.

• Do not install the actuator in a location where a human body may
come into contact. 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.

• When changing the head orientation, disconnect the cable and
turn the manual unlock to the UNLOCK position in advance. If

Instructions

• 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.

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

• Prevent foreign objects such as dust and liquids from
entering the interlock switch while connecting a conduit or
wiring.

• 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 in an area subjected to direct
sunlight.

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

• The locking strength is rated at 1400N. Do not apply a load
higher than the rated value. When a higher load is expected,
provide an additional system consisting of another 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 switch temperature
rises approximately 40°C above the ambient temperature (to
approximately 95°C while the ambient temperature is 55°C).
Do not touch to prevent burns. If cables come into contact
with the switch, use heat-resistant cables.

• Although the HS9Z-A51A/A52A actuators alleviate shock
when the actuator enters a slot in the interlock switch, make
sure that excessive shock is not applied. If the Rubber
Bushings become deformed or cracked, replace with new
ones.

may cause damage to the interlock

the head orientation is changed when the cable is connected
and the manual unlock is in the LOCK position, machines may
start to operate, causing danger to the operators.

• HS5L interlock switches are Type 2 low level coded
interlocking devices (ISO14119). According to ISO14119, the
following is required to minimize defeat when installing and
constructing systems:

1. Prevent dismantling or de-positioning of the elements of

the interlocking device by use of non-detachable xing (e.g.
welding, gluing, one-way screws, riveting). However, use of
non-detachable xing can be an inappropriate solution in
cases where a failure of the interlocking device during lifetime
of the machinery can be expected and a fast change is
necessary. In this case measures mentioned below, should be
used to provide the required level of risk reduction.

2. Apply at least one out of the four measures below.

➀ Mounting out of reach.
➁ Physical obstruction or shielding.
➂ Mounting in hidden position.
➃ Integration of defeat monitoring by means of status

monitoring/cyclic testing.

Mounting Examples

Refer to the following drawing for the installation. Mount the
interlock switch to a xed machine or guard, and actuator
on the hinged door. Do not mount both interlock switch and
actuator on the hinged doors. This may result in the actuator
being inserted at a wrong angle to the interlock switch,
resulting in malfunction.

Actuator Angle Adjustment (vertical/horizontal)

• Using the angle adjustment screw, the actuator angle can
be adjusted (refer to the dimensional drawing on page 16).
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.

HS5L Interlock Switches with Solenoid

Rotating the Head

The head can be rotated by removing the four screws from the
corners of the head and reinstalling the head in the desired
orientation. However, when changing the mounting direction of the
head after wiring, turn the manual lock release to the “UNLOCK”
position using the enclosed manual lock release key rst. When
reinstalling the head, make sure that no foreign object enters
the interlock switch. Tighten the screws tightly, without leaving a
space between the head and body, otherwise the interlock switch
may malfunction.
(Recommended tightening torque: 0.9 to 1.1 N·m)

Factory SettingHead can be rotated

Head Removal Detection Function

• Solenoid locks interlock switches are not equipped with the head
removal detection function.

• The head removal detection function is available only on spring
lock interlock switches with circuits VB, VD, and DD having two
or more lock monitor circuits. Removing the head will result in
disparity (41-42: OFF, 51-52: ON). Note that this function cannot
be detected with other models.

• Only the lock monitor circuit 41-42 turns off (open) when the
head is removed, such as when the head is rotated. The other
monitor circuit 51-52 turns ON (close). Be sure to connect the
lock monitor circuit (41-42) to a safety circuit.

Spring Loaded Actuator

• When using the actuator, be careful of protruding ends.

• Regardless of door types, do not use the HS9Z-BA5 actuator as
a door lock or a door stop.

• When an operator enters the hazardous zone, take safety
measures such as using a HS9Z-PH5 padlock hasp so that the
operator is not trapped inside and the machine cannot start by
mistake.

• Use the actuator only on sliding
doors. Do not use on hinged doors.

• As shown in the gure on the right,
do not insert the sliding actuator from
below. The actuator may fall out due
to shocks.

• The HS9Z-BA5 actuator can only be
used for HS5L interlock switches. Do
not use the HS9Z-BA5 actuator for
other products.

• Do not modify or disassemble the
actuator.

Installation (when installation reference is 0.8mm)

• The actuator protrudes out when the actuator is not inserted
(door is open) as shown in 1. in the drawing.

• The mounting reference position can be set to 0.8mm when the
actuator is fully inserted and the actuator protrudes up to the

0.8mm line.

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 safety 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

3.3mm line

Safety Precautions

Lock limit
line

• 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.

• The operating characteristics may change when the actuator is
used with the HS5L. Check the operating characteristics before
use.

Normal Position

Manual Unlocking

Position

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 solenoid is lost.

Cautions for Wiring

Use the following applicable wiring.
Stranded wire or solid wire (1 wire):

0.3 to 1.5mm2 (AWG22 to AWG16)
Make sure to strip the wire insulation 8
to 9mm from the end. If the strip
length is too short, the wire may fall
out. If the strip length is too long, it
may short circuit with other wires.
Twist the wires and make sure that
there are no wire whiskers.
When using stranded wires without
ferrules, make sure that the core wires
have not been loosened.

• For wiring, use screwdrivers as
shown in the right. (The shape of the
tip of the screwdriver is in accordance with DIN5264)

• The inserting port of the wire and screwdriver, and direction of
the tip is as shown in the diagram below.

Instructions

Wire connection method

1. Insert the screwdriver into
the square-shaped port from
a slightly slanted angle as
shown, until the screw-driver
tip touches the bottom of the
spring. Make sure that the
direction of the blade edge is correct.

2. Push in the screwdriver until it
touches the bottom of the port.
The wire port is opened, and the
screwdriver is held in place.
The screwdriver will not come
off even if you release your hand.

3. While the screwdriver is retained
in the port, insert the wire or
ferrule into the round-shaped
wire port.

4. Pull out the screwdriver. The
connection is now complete.

Safety Precautions

When using wires with insulation diameter of ø2.0mm or less, do
not insert the wire too deeply where the insulation inserts into
the spring clamp opening. Make sure that the wire insulation is
stripped 8 to 9mm and the wire is inserted to the bottom.

Incorrect Correct

Insulation inserted
too deep

Wire inserted to
the bottom

If there is a need to insert the screwdriver while holding the
interlock switch with hands, be careful not to injure your ngers
with the tip of the screwdriver.
Connect one wire to one wiring port.
(According to IEC 60204 (JIS 9960-1) 13.1.1 General Requirement)

Installing the HS9Z-JP5L Jumper

HS9Z-JP5L is used on a 4-contact interlock switches to connect
the door monitor circuit (11-12) / (21-22) in series with the lock
monitor circuit (41-42)/(51-52) for safety circuit input.
For example, when wiring 12 and 41:

Safety Precautions

• For circuit code DD, a jumper is wired between 12-41 and 22-51
at factory setting.

• Be sure to connect only to 12-41 and 22-51.

Connector Wiring

Perform wiring according to following procedures 1. to 4.

1. Insert the cable into the connector. Leave A and B untightened.

2. Open the cover and insert the cable into the cover.

3 Wire to the terminals.
4 Tighten in the order of A → Cover → B.

Interlock switch Cover

* To remove the wiring, turn the power off and then unwire in the

order of B → cover (→waterproof gasket → A).

Note: When removing A, because the waterproong gasket is

tightly attached to the cable, pull out the gasket carefully
with tweezers so that the gasket is not damaged before
loosening A. Otherwise, the cable will rotate together with A
when loosened, and might break due to excessive twisting.
Also, when reassembling, place the gasket in the original
position rst.

Safety Precautions

• When opening the cover, be
careful not to lose the cover
mounting screw.

• When tightening connector
B, insert the cable into the
connector, and set it to a
position where the gasket
of the connector holds the
cable sheath, otherwise, its
waterproof performance might
be impaired.

• Tighten the connector in
order of A → B. If connector
B is tightened rst, the wiring
connected to the spring
clamp terminal may become twisted when tightening A, causing
disconnection or malfunction.

• Tighten the connectors with tightening torque according to the
torque value recommended by the connector manufacturer.
Otherwise, waterproof performance might be impaired.

• Do not exert excessive load, pressure, or tensile force on the
cable, otherwise, disconnection or malfunction might occur.
