CAUTION
Solenoid lock type
• This safety switch is designed to lock the actuator while the solenoid is energized
and to release it when deenergized.
• When the power to the solenoid is interrupted by accident, such as disconnection,
the lock is released before a machine stops ompletely. Then, the worker may be
exposed to hazards.
• This safety switch can be used only for limited applications which do not especially
need to be locked for safety.

HS9Z-A11T
HS9Z-A12T
For Mounting
• Do not apply an excessive shock to the safety switch when opening or closing the
door. A shock to the safety switch exceeding 1,000 m/s2may cause failure.
• Provide a door guide, and ensure that force is applied on the safety switch only in
the actuator insertion direction.
• Do not pull the actuator while it is locked. Also, regardless of door types, do not use
the safety switch as a door lock. Install a separate lock as shown in section 3.
• Ensure that the safety switch is installed on a flatmounting surface, and provide
sufficient strengthto the mounting surface so that it will not be distorted during
operation. Make sure that no foreign objects are caught between the safety switch
and mounting surface. Uneven surface, distorted surface, or foreign objects may
result in the malfunction of safety switch.
• Entry of foreign objects in the actuator entry slot may affect the mechanism of the
switch and cause a breakdown. If the operating atmosphere is contaminated, use a
protective cover to prevent the entry of foreign objects into the switch
through the actuator entry slots.
• Make sure to install the product in a place where it cannot be damaged.
Make sure to conduct a proper risk assessment evalua ion before using
the product, and use a shield or a cover to protect the product if need be.
• While the solenoid is energized, the switch temperature rises approximately 40°C
above the ambient temperature (to approximately 95°C while the ambient tempera-
ture is 55°C). Keep hands off to prevent burns. If cables come into contact with the
switch, use heat-resistant cables.
• Solenoid has polarity. Be sure to wire correc ly. Do not apply voltage that exceed the
rated voltage, otherwise the solenoid will be burnt out.
• Do not fasten and loosen the conduit at he bottom of the safety switch.
• Use the dedicated actuators only. Other actuators will cause damage to the switch.
• Be careful not to injure yourself with the screwdriver tip when wiring the terminals.
• Be careful not to damage the square-shaped screwdriver port when inserting the
driver into it in order to wire the terminals. Inserting the screwdriver with too much
strength may damage the product.
• Before using the following accessories, be sure to refer to the instruc ion manual for
the respective accessory and follow the instructions in the manual to ensure correct
use. HS9Z-FL5
CAUTION
• HS1T Series Safety Switches are Type 2 low-level coded interlocking devices (EN
ISO / ISO14119). The following system installation & mounting instructions are EN
ISO / ISO14119 requirements to prevent function failure from the interlock switch.
1. Using permanent fixing methods (e.g. welding, rivets, special screws...etc) to
prevent dismantling or de-positioning of the interlock device. However, perma-
nent fixing methods are not an adequate solution if you expect the interlock
device to fail during the machinery lifetime, or if you need to replace the prod-
uct in quick manner. In these situations, other measures (see 2.) should be put
in place to reduce the risks of function failure.
2. At least one of the following measures should be applied to prevent function
failure.
(1) Mounting the interlock device in a place out of reach from workers
(2) Using shielding protection to prevent physical obstruction of the device
(3) Mounting the interlock device in a hidden position
(4) Integrate status monitoring & cycling testing of the device to the control
system to prevent product failure.
• Regardless of door types, do not use the safety switch as a door stop. Install a
mechanical door stop to the end of the door to protect the safety switch against
excessive force.
• Mount the actuator so that it will not hit the operator when the door is open, other-
wise injury may be caused.
• Pay attention to the management of spare actuator. Safety function of door inter-
lock switch will be lost in case the spare actuator is inserted into the interlock
switch. Ensure that the actuator is firmly fastened to the door (welding, rivet, special
screw) in the appropriate location, so that the actuator cannot be removed easily.
• Do not cut or remodel the actuator, otherwise failure will occur.
• If multiple safety components are wired in series, the Performance Level to
ISO13849-1 will be reduced due to the restricted error detection under certain
circumstance.
• The insulation of the cable has to withstand environmental influences.
• The entire concept of the control system, in which the safety component is
integrated, must be validated to ISO13849-2.
• When there is a displacement of safety switch and actuateor, the actuator may hit the
entry slot of safety switch hardly, thus damaging the entry slot and acutuator. The
rubber cushions on the HS9Z actuator prevent the actuator from damaging the entry
slot by absorbing the shock with movement flexibility. Do not, however, exert
excessive shocks, otherwise the failure of safety switch may be caused.
• The rubber cushions may deteriorate depending on the operating enviroment and
conditions. Immediately replace the deformed or cracked rubber cushions with new
ones.

The HS1T allows manual unlocking of the actuator to precheck proper door opera-
tion before wiring or turning power on, as well as for emergency use such as a power
failure.
(Type HS1T-□7Y)
If the actuator is not unlocked althoug the solenoid is deenergized, the actuator can
be unlocked manually.
CAUTION
• Before manually unlocking the safety switch, make sure the machine has come to a
complete stop. Manual unlocking during operation may unlock the switch before the
machine stops, and the function of safety switch with solenoid is lost.
• While the solenoid is energized, do not unlock the actuator manually (solenoid lock
type).
• Do not apply excessive force (0.45 N•m or more) to he manual unlock key. Otherwise
the manual unlock switch will be damaged. Do not attach the key to the switch
intentionally (the key is designed to fall off when the operator's hand is off the key).
• Do not leave the manual unlock key attached to the switch during operation. This is
dangerous because the switch can always be unlocked while the machine is in
opera ion.
CAUTION
• Install the HS1T to ensure that a worker can operate the rear unlock button from
inside the safety hedge (the dangerous area). It is dangerous to install the HS5L in
the position where the rear unlock button can be operated from outside the the
safety hedge (the dangerous area), because it is possible to unlock while the
machine is opera ing.
• Use hand to press the button, and do not use a tool. Do not apply excessive force
to the rear unlock button.
• To change the normal position to the
manual unlocking position as shown
above, turn the key fully (90 degrees)

*9 This locking monitoring marking has been newly described in section 9.2.1 of
EN ISO / ISO14119. It indicates that any devices with this marking meet the
following EN ISO / ISO 14119 requirements:
- General (- General requirements for guard locking devices) (Section 5.7.1) *
- Locking monitoring (- Locking monitoring for guard locking devices) (Section
5.7.2.2)
When a lock monitor circuit (contact) has the locking monitoring marking, it
means that one circuit (contact) can monitor the position and the locking
function of the protective door. (The locking monitoring circuit (contact) turns
ON only when the protective door is closed and locked.)
*note Both types of HS1T safety switches - spring lock type switches and solenoid
lock type switches - have obtained the locking monitoring certifica ion marking.
Based on risk assessment results, solenoid lock type switches can be used
only for limited applications which do not especially need to be locked for
safety.
