3 Basic insulation of 2.5kV impulse withstand voltage is ensured between
different
contact circuits and between contact circuits and LED or solenoid in the
enclosure.
When both SELV (safety extra low voltage) or PELV (protective extra low
voltage)
circuits and other circuits (such as 230V AC circuits) are used for the
solenoid
power and contact circuits at the same time, the SELV or PELV requirements are
not met any more.
4 The actuator locking strength is rated at 1 ,400N of static load . Do
not apply a load
higher than the rated value. When a higher load is expected to work on the
actuator, provide an additional system consisting of another safety switch
without
lock (such as the HS5D safety switch) or a sensor to detect door opening and
stop
the machine.
5** F1 max. is maximum force. The actuator’s guard-locking force FZh is
calculated in
accordance with GS-ET-19:
*6 Make sure that a fast acting fuse for short-circuit protection trips
before overheating of the
wires.
Mounting Examples
- Install the interlock switch on the immovable machine or guard, and install the actuator on the movable door. Do not install both interlock switch and actuator on the movable door, otherwise the angle of insertion of the actuator to the safety switch may become inappropriate, and failure will occur.
The HS5E-K Head
- Changing the Mounting Directions of the HS5E-K Head. The head of the HS5E can be mounted in four directions by removing the four screws from the corners of the HS5E-K head.
Mounting Directions of the HSSE-K Head
- When replacing the HS5E-K head, make sure that no foreign object enters into the safety switch. Tighten the screws tightly, without leaving space between the head and body, otherwise the safety switch may malfunction.
Don’t remove the screws of head expect when the mouting directions of head is changed.
Mounting the Head
-
Do not use the plastic and metal head of the HS5D interlock switches. Be sure to use the metal head for the HS5E-K. When using these HS5D adjacently, ensure that the heads are not interchanged.
-
Head Removal Detection Function
When the key is operated, the operation of the main circuit (11-42)/monitor circuit (41-42) and monitor circuits (51-52, 61-62) are the same. However, when the head is removed, disparity is detected (11-42/41-42: OFF, 51-52/61-62: ON). The disparity of the contacts detects the removal of the head.
Installing the Manual Rear Unlocking Button (Type HSSE-K□ L)
- After installing the interlock switch on the panel, put the manual rear unlocking button (supplied) on the rod on the back of the interlock switch, and fasten using the mounting screw. When installing on the aluminum frame of the thickness of 6mm or more, use the rear unlocking button for frame kit (HS9Z-FL5 □) sold separately.
After installing the manual rear unlocking button, apply Loctite to the screw so that the screw does not become loose. The base is made of glass-reinforced PA66 (66 nylon). The mounting screw is iron. Take the compatibility of plastic material and Loctite into consideration.
Minimum Radius of Hinged Door
-
When using the safety switch for a hinged door, the minimum radius of the applicable door is shown in the following figures.
When the center of the hinged door is on the extension line of the actuator mounting surface.
-
When the center of the hinged door is on the extension line of the contact surface of actuator and safety switch.

The values shown above are based on the condition that the actuator enters and exits the actuator entry slot smoothly when the door is closed or opened. Since there may be deviation or dislocation of the hinged door, make sure of correct operation in the actual application before installation.
Adjusting the Angle Adjustable (vertical/horizontal) Actuator (Type HS9Z-A53/A55/A55S)
- Using the angle adjustment screw (M3 hexagon socket set screw), the actuator angle can be adjusted up to 20°(refer to dimensions).
- The larger the actuator angle, the smaller the applicable radius of the door swing. After installing the actuator, open the door. Then adjust the actuator angle so that the actuator enters the entry slot of the safety switch properly.
- After adjusting the actuator angle, apply loctite or the like on the adjustment screw to prevent loosening.
(Type HS9Z-A53)
Tightening torque of angle adjustment screw: 0.8 N•m.
(Type HS9Z-A55)
Use screw locking agent that is compatible with the base material.
Base: PA66 (66 nylon) of glass reinforced grade
Angle adjustment screws: stainless steel
{Type HS9Z-A55S)
Use screw locking agent that is compatible with the base material.
Plate: stainless steel
Base : PA66 (66 nylon) of glass reinforced grade
Angle adjustment screws : stainless steel
Actuator Mounting Reference Position
As shown below, the mounting reference position of the actuator inserted into
the safety switch is:
(Type HS9Z-A53)
The actuator stop film placed on the actuator touches the safety switch
lightly.
(Except Type HS9Z-A53)
The actuator and actuator cover touches the actuator stop placed on the safety
switch lightly.
{After mounting the actuator, remove the actuator stop from the safety
switch.)
Actuator Mounting Tolerance
- Mounting tolerance of the actuator is 1.0mm in the four lateral directions.
- Make sure the actuator can be inserted into the entry slot without any issue.
- When closing the door, the actuator is inserted and locked within a certain distance from the reference position. After the actuator has been locked, the contact operation is not affected by the actuator movement in the locked state.
| (Actuator deviation)+ (Door movement)
---|---
HS9Z-A51| < 3.3mm
HS9Z-A52
HS9Z-A51A HS9Z-A52A| s 4.6mm
HS9Z-A53| s 5.6mm
HS9Z-A55 HS9Z-A55S| < 4.6mm
For Type HS9Z-A51A/A52A actuator
- When there is a displacement of safety switch and actuator, the actuator may hit the entry slot of safety switch hardly, thus damaging the entry slot and actuator. The rubber cushions on the HS9Z actuator prevent the actuator from damaging the entry slit 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 environment and conditions. Immediately replace the deformed or cracked rubber cushions with new ones.

*8 In the case of HS9Z-A51A and HS9Z-A52A, using two M4 screws and two attached washers, fasten the actuator securely on the door.
Precautions for Operation
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/s2 may 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 3.
-
Do not open the lid
1
of the switch. Loosening the screws may cause damage to the 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 evaluation before using the product, and use a shield or a cover to protect the product if need be.
-
Do not fasten and loosen the conduit at the bottom of the safety switch.
-
When wiring, make sure that liquid such as water and oil does not intrude from the tip of cable.
-
When bending the cable during wiring, secure the cable radius of 30mm at the minimum.
-
Use the dedicated actuators only. Other actuators will cause damage to the switch.
-
Turn off the power to the safety switch before starting installation, removal, wiring, maintenance, and inspection on the safety switch. Failure to turn power off may cause electrical shocks or fire hazard.
-
Do not disassemble or modify the switch. Also do not attempt to disable the interlock switch function, otherwise a breakdown or an accident will result.
-
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, otherwise injury may be caused.
-
Turnoff the power to the safety switch before starting installation, removal, wiring, maintenance, and inspection on the safety switch. Failure to turn power off may cause electrical shocks or fire hazard.
-
Mount the actuator so that it will not hit the operator when the door is open, otherwise injury may be cvaused.
-
Pay attention to the management of spare actuator. Safety function of door interlock 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 EN ISO 13849-1 will be reduced due to the restricted error detection under certain circumstance.
-
The entire concept of the control system, in which the safety component is integrated, must be validated to EN ISO 13849-2.
-
Do not mount the interlock switch facing down as shown in the figure on the right. The key may fall due to vibration.
Key
-
Be sure to take the following precautions.
Otherwise, failure or damage may occur. -
When using the key, insert the key all the way.
-
Do not apply a rotative force when inserting or removing the key.
-
Also, do not pull the key during operation. Otherwise failure or damage may occur.
-
Other than the standard key, there are 15 key variations. Be sure to use a key and cylinder with the same number.
-
Do not apply excessive force to the key. Otherwise failure or damage may occur.
-
With the key in the UNLOCK position, do not turn the key to the LOCK position with the actuator removed (door open). Otherwise failure or damage may occur.
For the Rear Unlock Button (Type HSSE-K □ L)
-
The rear unlock button is used for an emergency escape when the worker is confined in the safety hedge (the dangerous area). (The rear unlock button is according to EN ISO/ ISO14119 (2013) ,GS-ET-19)
-
The lock is released when the rear unlock button is pressed, and the door can be opened.
-
To return to locked status, pull back the button.
While the Rear Unlock Button is depressed, the main circuit remains open and the door is unlocked.
-
Install the HS5E-K 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 HS5E-K 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 operating.
-
Use hand to press the button, and do not use a tool. Do not apply excessive force to the rear unlock button.
Using the HSSE-K in an explosive atmosphere
- By using the HS5E-K with an explosion-proof cover (HS9Z-BC51, optional) or a door handle actuator (HS9Z-DH □, optional), and connecting the EB3N safety relay barrier (EB3N- □□, optional), the HS5E-K can be used as an intrinsically safe explosion- proof product.
- When using in an explosive atmosphere, see the EB3N safety relay instruction manual or the user’s manual.
- For operating conditions of the explosion-proof cover, see the instruction manual supplied with the explosion-proof cover.
