1. Basic insulation of 2.5kV, 1.5kV impulse withstand voltage is ensured between different contact circuits and between contact circuits and LED or solenoid in he 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 he solenoid power and contact circuits at the same time, the SELV or PELV requirements are not met any more.
2. The actuator locking strength is rated at 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 HS6B/HS7A safety switch) or a sensor to detect door opening and stop the machine.
3. F1max. is maximum force. The actuator’s guard-locking force Fzh is calculated in accodance with GS-ET-19:
4. 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.

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

|

Minimum Radius

---|---
R1| R2| R3| R4

HS9Z-A62/-A62S

| 230mm| 230mm| 160mm| 160mm
HS9Z-A65/-A66| 70mm (Horizontal Swing)| 70mm (Vertical Swing)| 50mm (Horizontal Swing)|

50mm (Vertical Swing)

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 devia ion or dislocation of the hinged door, make sure of correct operation in the actual application before installation. When inserting an actuator into the slot, make sure to arrange the shapes in the same direction, as shown on the right.

The Adjustable (vertical/horizontal) Actuator

• 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 he 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. Use screw locking agent that is compatible with the base material. Base : PA66 (66 nylon) of glass reinforced grade Angle adjustment screws : stainless steel Installing the Safety Switch and Actuator

• When installing the actuator, position the actuator using the actuator stop (for positioning the entry slot center and mounting reference position).

• As shown on the right, the mounting reference position of the actuator when inserted in the safety switch is where the actuator stop touches the actuator.

• Install a door stop as shown on the right to protect the safety switch and actuator against excessive force. Do not use the safety switch as a door stop, otherewise the safety switch will be damaged.

• After removing the actuator stop, ensure that the actuator is installed within the tolerances shown below.
  From he entry slot center of the safety switch (5, 6) : ±1.0mm
  The gap between the actuator shoulder and the safety switch surface (7)
  HS9Z-A61/-A62/-A65/-A66 : 1.9mm or shorter
  HS9Z-A62S : 1.3mm or shorter

• To ensure correct operation, it is recommended to fasten the door using a latch to achieve the above tolerance values.

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

• Perform operation test before starting operation in order to confirm the open/close operation of contacts and locking/unlocking operation.

• When the actuator is pulled while locked in the safety switch, the actuator moves within the range shown below.
  HS9Z-A61/-A62/-A65/-A66 : 4.1mm maximum from the safety switch surface
  HS9Z-A62S : 3.5mm maximum from the safety switch surface
  The open/close status of the contacts are maintained within the range.When a gap is caused because of actuator relocation, make sure that the gap does not lead to new risks.

HS9Z-A61, HS9Z-A62, HS9Z-A62S ACTUATOR

• When there is a displacement of safety switch and actuator, the actuator may hit the entry lot 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.

Recommended Screw Tightening Torque

*8 When he torque is not enough to recommended screw tightening torque, make sure that he screw do not become loose by using adhesive sealants etc. to keep right operation and mounting positioning.

Mounting HS9Z-A62S actuator

Using two M4 screws and plate, fasten the actuator securely on the door.
Plate has directionality. Do not lose the plate. The actuator may fall off from the door if there is no plate, and the actuator does not properly

The tensile strength of the HS9Z-A62 actuator is 100N. If an excessive tensile force is applied, the actuator may fall off the door. When a tensile force exceeding 100N is expected, use the HS9S-A62S actuator with a plate.

The tensile strength of the HS9Z-A62 actuator is 100N. If an excessive tensile force is applied, the actuator may fall off the door. When a tensile force exceeding 100N is expected, use the HS9S-A62S actuator with a plate.

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 1,000m/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 section 3.

• 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 safe place out of reach. 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 35°C above the ambient temperature (to approximately 85°C while the ambient temperature is 50°C). Keep hands off to prevent burns. If cables come into contact with the switch, use heat-resistant cables.

• When the actuator is locked or unlocked, the NC lock monitor contacts and NO unlock monitor contacts cause bouncing. When designing a control circuit, take the bouncing into consideration (reference values: 20ms).

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

• Do not fasten or loosen the conduit at the bottom of he safety switch.

• When wiring, make sure that liquid such as water and oil does not intrude from the end of the cable.

• When bending the cable during wiring, secure the cable radius of 30mm at the minimum. Do not apply an excessive shock, such as tensile and compressing force, to the connection part of the cable and switch.

• Use the proprietary actuators only. Other actuators will cause damage to the switch.

• 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.

• 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.

• HS6E 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, permanent 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 product 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. When a higher load works on the lock portion of the safety switch, the actuator may not unlock.

• Mount the actuator so that it will not hit the operator when the door is open, otherwise 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.

• 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 he 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.

For Manual Unlocking

• Spring lock type : The HS6E allows manual unlocking of the actuator to precheck proper door operation before wiring or turning power on, as well as for emergency use such as a power failure.
• Solenoid lock type : If the actuator is not unlocked although the solenoid is deenergized, the actuator can be unlocked manually

Manual Unlocking Method

• When using the manual unlock key :
  To change the normal position to the manual unlocking position as shown above, turn the key fully (90 degrees) using the proprietary key supplied 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.
  Note: When manually unlocked, the switch will keep the main circuit disconnected and the door unlocked.

• When unlocking by pushing he plate ins aide the safety switch :
  Remove the screw at the side of the safety switch and insert a small screwdriver. Push the plate inside the safety switch toward the LED pilot light using a small screwdriver until the actuator is unlocked. See the figure on the right.

• 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 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. Do not attach the key to the switch intentionally (the key is designed to fall off when the operator’s hand is off he key).

• Unlocking by pushing the plate inside the safety switch must be perfumed in emergency only. After unlocking, make sure to tighten the M4 screw to the tightening torque of 0.3 to 0.5 Nm. Do not apply excessive force to the M4 screw.
  Otherwise the safety switch is damaged. Make sure that all screws are installed, otherwise the waterproof capability is lost.

Contact Operation

Contact Configuration and Operation

9 The Actuator is inserted, and HS6E is locked.

• 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-A61, A62, A65, A66 actuators. (For HS9Z-A62S actuator, decreases 0.6mm to contact operations)
• Terminals 12-41 are connected together internally. Use terminals 11-42 for safety circuit inputs. (without HS6E-V□)
• Indicator turns on when solenoid is energized.

When using the outputs from the HS6E-V safety switch as inputs to safety circuits, connect the door monitor circuits (11-12, 21-22, 31-32) and lock monitor circuits (41-42, 51-52) in series. (GS-ET-19)
Then, the contact rating for he lock monitor circuit is applied.(HS6E-V□)
