2 Basic insulation of 4kV 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.
3 The actuator locking strength is rated at 1,500N 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.
*4 F1max. is maximum force. The actuator’s guard-locking force Fzh is calculated in accodance with GS-ET-19 :

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 he angle of insertion of the actuator to he safety switch may become inappropriate, and failure will occur. 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 he center of the hinged door is on the extension line of he actuator mounting surfase.
When the center of the hinged door is on the extension line of the contact surface of actuator and safety switch.

• L-shaped actuator : HS9Z-A2
• Adjustable actuator : HS9Z-A3

CAUTION
The figures shown above are based on the condition that the actuator enters and exits the actuator entry slot smoothry 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.
Actuator Mounting Reference Position
• As shown below, the mounting reference position of the actuator inserted into the safety switch is the actuator cover or stop film touches the safety switch ligh ly. (After mounting the actuator, remove the actuator cover or stop film from the safety switch.)
Note : During installation, ensure that there is no excess force applied between the safety switch and actuator by installing a door stopper as shown in the image. Actuator Mounting Tolerance

• Mounting tolerance of the actuator is 1.0mm from the center of the actuator to up, down, right, and, left.

• Make sure the actuator can be inserted into the entry slot without any issue.

• Actuator can move 3.8mm (HS9Z-A1 and -A2) / 2.7mm (HS9Z-A3) from the mounting position without affecting the contact operation.
  

• When closing the door (when actuator is inserted into safety switch), the solenoid is locked as the actuator has reached at approx. 6.4mm (HS9Z-A1 and -A2) / 5.3mm (HS9Z-A3) to the moun ing reference position.

CAUTION
*5 To ensure that the door locks correctly, install the actuator in a position that is within 6.4 mm (HS9Z-A1 and -A2) / 5.3 mm (HS9Z-A3) of the standard installation position. If the actuator is not in the correct position, the door will not lock and there is a risk that an incorrect safety circuit may turn ON.
Recommended Screw Tightening Torque

Name or Use

|

Screw Tightening Torque

---|---
For mounting the safety switch (M5 hexagon socket head cap screw) 6| 4.5～5.5 N•m
For moun ing the actuator (M6 hexagon socket head cap screw) 6| 4.5～5.5 N•m
For moun ing the lid (M4)| 1.1～1.3 N•m
Connector (G1/2)| 2.7～3.3 N•m
Plug for Unused Conduit Hole (G1/2)| 1.8～2.2 N•m
Screw Terminal No.1 to 6 (M3)| 0.4～0.6 N•m
Screw Terminal No.7,8 (M3.5)| 0.9～1.1 N•m
Ground Terminal screw (M4)| 0.9～1.1 N•m
Angle adjusting screw of HS9Z-A3 (M3 hexagon socket head cap screw)| 0 8 N•m

CAUTION
*6 When the torque is not enough to recommended screw tightening torque, make sure that the screw do not become loose by using adhesive sealants etc. to keep right opera ion and mounting positioning.
Adjusting the Angle Adjustable Actuator (HS9Z-A3)

• Using the angle adjusting screw (M3 hexagon socket head screw), the actuator angle can be adjusted up to 20°.

• 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 adjusting screw to prevent loosening.

Precautions for Operation

Installation

• 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 2 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 item 3.

• When opening the safety switch lid to wire, open the lid 1 only. (See the figure on the right.)Never remove other screws, otherwise the safety switch may be damaged.

• The safety switch cover can be only removed or installed with the special L-shaped key wrench supplied with the switch.

• 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.

• Solenoid has polarity. Be sure to wire correctly. Do not apply voltage that exceed the rated voltage, otherwise the solenoid will be burnt out.

• Avoid foreign objects such as dust, liquid, and oil from entering the switch while connecting a conduit or wiring.

• 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.

• Use only the designated actuator for the HS1C. Other actuators will cause a breakdown of the switch.

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.
• Use wires of a proper size to meet voltage and current requirements. Tighten the terminal screws to a recommended tightening torque of 1.0N･m. Loose terminal screws will cause unexpected heating and fire hazard during operation.

CAUTION

• Regardress of door types, do not use the safety switch as a door stop. Install a mechanical door stop at the end of the door to protect the safety switch against an excessive force.
• Mount the actuator so that it will not hit the operator when the door is open, o herwise injury may be caused.
• 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 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.

Manual Unlocking

• The HS1C allows manual unlocking of the actuator to precheck door operation before wiring or turning on power, as well as for emergency use such as a power failure.
• Remove the screw from the side of the safety switch using the wrench for mounting the lid. Push the lever inside the safety switch towards the pilot light using a small screwdriver until the actuator is unlocked. See the figure on the right.

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.
• After the unlocking operation, be sure to turn the screw to the original position for safety.
