The HS1T Head
- Changing the Mounting Directions of the HS1T Head The head of the HS1T can be changed in four directions by pulling up the rotation stopper screw of the HS1T head with a minus driver.
The head rotates in the range of movement as in the diagram below, based on the mounting direction at the time of shipment.
How to Change the Mounting Direction
- Rotate the minus driver in the direction of the arrow and pull up the rotation stopper screw.
- Once you’ve pulled up the rotation stopper screw to its stopping point, rotate the head to your desired direction.
- When the head has been rotated to your desired mounting direction, align the a, marks of the head and case, and then tighten the rotation stopper screw.
WARNING
Mounting Directions of the HS1T Head
- There is a range of movement to the head. Do not forcibly rotate the head over its range of movement. There is a risk of damage.
- There is a risk of damage if the rotation stopper screw is forcibly tightened without aligning the A marks of the head and case.
- Apply loctite or the like to on the rotation stopper screw to prevent loosening.
- When replacing the HS1T head, make sure that no foreign object enters into the safety switch.
- Tighten the rotation stopper screw of the head tightly, otherwise the safety switch may malfunction.
- Don’t loosen the rotation stopper screw of the head except when the mounting directions of the head is changed.
Installing the Rear Unlock Button and Indicator (Type HS1T-❑L)
- Insert the rear unlock indicator (supplied) in the indicator guide hole on either the left or right side of the safety switch and attach the ring part to the rod on the rear side. After installing the safety switch on the panel, put the rear unlock button (supplied) on the rod, and fasten using the mounting screw (supplied).
When installing on the aluminum frame with a thickness of 6mm or more, use the rear unlock button for the frame kit (HS9Z-FL5❑) sold separately.

Installing the slot plug
- When not in use, close up the safety switch actuator entry slots with slot plugs to prevent dust from entering.
- Actuator entry slots on the front come closed up with slot plugs at time of shipment. When replacing, please use the tool as shown.
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/s’ 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 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 evaluation 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 correctly. Do not apply voltage that exceed the rated voltage, otherwise the solenoid will be burnt out.
- Do not fasten and loosen the conduit at the 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 instruction manual for the respective accessory and follow the instructions in the manual to ensure correct use. HS9Z-FL5
WARNING
- 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.
CAUTION
-
HS1T Series Safety Switches are Type 2 low-level coded interlocking devices (EN ISO / IS014119). The following system installation & mounting instructions are EN ISO / IS014119 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 IS013849-1 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 IS013849-2.
For Manual Unlocking
- To change the normal position to the manual unlocking position as shown above, turn the key fully (90 degrees) using the special key included with the switch.
- Using the switch with the key being not fully turned(less than 90 degrees) may cause damage to the switch or errors.
- When manually unlocked, the switch will keep the main and lock monitor circuit disconnected and the door unlocked.
(Type HS1T-❑4)
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 the 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 operators 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 operation.
For the Rear Unlock Button and Indicator (Type HS1T-❑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 /15014119, GS-ET-19)
- The lock is released when the rear unlock button is pressed, and the door can be opened
- To return to the locked status, pull back the button. While the rear unlock button is depressed, the main circuit remains open and the door is unlocked.
- Each time the rear unlock button is pressed, the indicator is displayed on the side of the safety switch. Enables checking of the unlock status from outside the safety hedge.
- Use the rear unlock indicator by attaching it to the display area on either side of the safety switch.
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 operating.
- Use hand to press the button, and do not use a tool. Do not apply excessive force to the rear unlock button.
Contact Operation
Contact Configuration and Operation
- Contact operation is based on the condition that the actuator is inserted into the center of the safety switch slot.
- Contact operation shows the HS9Z-A11T/Al2T actuator.
- Use main circuit or monitor circuit with for the input to safety circuit.
- Indicator turns on when solenoid is energized.
CAUTION
*9 This locking monitoring marking has been newly described in section 9.2.1 of EN ISO / IS014119. 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 HS5L safety switches – spring lock type switches and solenoid lock type switches – have obtained the locking monitoring certification 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.
