HS5D Head Removal Detection Function (Screw Terminal No.11-12)

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.
  
  (Examples of Mounting on Hinged Doors)
  

Changing the Mounting Directions of the HS5D Head

• The head of HS5D can be mounted in four directions by removing the four screws on the corners of the HS5D head.
  

Mounting Directions of the HS5D Head

• When replacing the HS5D head, make sure that no foreign object enters into the safety switch.
• Tighten the screws tightly, oherwise he safety switch may malfunction.
• Don’t remove the screws of head expect when the mooting directions of head is changed.
• When tightening the screw in the head section with an electric screwdriver or similar tool, temporarily tighten the first part of the screw by hand first, and then tighten with the electric screwdriver.

Mounting the HS5D Head

• Do not use the metal head for the HS5L with lock type. Be sure to use the plastic head or metal head for the HS5D. Be sure to use the correct head
  

HS5D Head Removal Detection Function

• The the NC contacts of the two main circuits (11-12, 21-22) are operated similarly by the actuator. But, when the HS5D head is removed, the NC contact of the main circuit (11-12) is opened, and other NC contact (21-22) remains closed.
  

• When the HS5D head is removed, the NC contact of the main circuit (11-12) is opened, and other NC contact(s) remain closed. Use the NC contact of the main circuit (11-12) for the safety circuit.
• Turn off he power when using this function.

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 surfade.

The above example are based on the condi ion 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)

• 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

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 he actuator can be inserted into the entry slot without any issue.
• When closing the door, the actuator is inserted within a certain distance from the reference position. The contact operation is not affected by the actuator movement.
  

HS9Z-A52
HS9Z-A51A
HS9Z-A52A| ≤ 3.0 mm
HS9Z-A55| ≤ 2.5 mm

HS9Z-A51A/HS9Z-A52A

• 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.

Recommended Screw Tightening Torque

For moun ing the safety switch
(M4 screw) 1| 1.8 to 2.2 N ・m
For moun ing the HS5D lid (M3)| 0.2 to 0.4 N ・m
Terminal screw (M3)| 0.6 to 0.8 N ・m
Cable gland| 2.7 to 3.3 N ・m
For mounting the HS5D head (M3)| 0.9 to 1.1 N ・m
For mounting the actuator
(HS9Z-A51: M4 screw) 1 (HS9Z-A52: M4 Phillips screw)
(HS9Z-A51A/A52A/A55: two M4 screws)

*1, 2

| 1.8 to 2.2 N ・m
0.8 to 1.2 N ・m
1.0 to 1.5 N ・m

1. When the torque is not enough to recommended screw tightening torque, make sure hat the screw do not become loose by using adhesive sealants etc. to keep right operation and mounting positioning.
2. 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

• Do not apply an excessive shock to the safety switch when opening or closing the door. A shock to the safety switch exceeding 1000 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.

• 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.

• 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 he switch through the actuator entry slots.

• When wiring or installing a gland, make sure that no foreign objects, dust, and water enter into the safety 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.

• Use only the designaged actuator for the HS5D. Other actuators will cause a breakdown of 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 safety switch function, otherwise a breakdown or an accident will result.
• 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.

• HS5D 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 obstruc ion 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.

• Do not use the safety switch as a door stop on any type of doors. Install
  mechanical door stops on the door ends to protect the safety switch from excessive force.

• 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 safety switch will be lost in case the spare actuator is inserted into the safety 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.

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-A51 actuator.
