Mounting Examples

Install the safety switch on the immovable machine or guard, and install the actuator on the movable door. Do not install both safety switch and actuator on the movable door, otherwise failure will occur.
Note : When inserting an actuator into the slot, make sure to arrange the shapes in the same direction, as shown on the right.

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 using L-shaped actuator (HS9Z-A62)

When using angle adjustable actuator (HS9Z-A65/HS9Z-A66)

Note: 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 stop touches the safety switch lightly.
Note: After mounting the actuator, remove the actuator stop from the safety switch.

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 2.1mm from the mounting position without affecting the contact operation.
  

Adjusting the Angle 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 the actuator enters the entry slot of he 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

HS9Z-A61, HS9Z-A62 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 operatiing environment and conditions. Immediately replace the deformed or crasked rubber cushions with new ones.

Recommended Screw Tightening Torque

CAUTION

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 operation and mounting positioning.

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/s2 may cause failure.

• Provide a door guide, and ensure that force is applied on the safety switch only in the actuator insertion direction.

• 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 dose not intrude from the tip of cable.

• When bending cable at wiring, secure the cable radius of 40mm at the minimum.

• Be sure to use the dedicated actuator only, and do not operate the HS6B safety switch with anything other than the dedicated actuator. Otherwise, the safety of the system may not be maintained.

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 safety switch function, otherwise a breakdown or an accident will result.

CAUTION

• HS6B 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.

  • 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, o her measures (see 2.) should be put in place to reduce the risks of function failure.
  • 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.

• 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, 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

Wiring

Identification of terminal numbers

• When wiring, the identification of terminal number on each contact is made by colored wire.

• The following shows a safety (main) contact and an auxiliary contact for three contacts and two contacts types.
  

• When wiring, cut unnecessary wires such as dummy insulator (black) and / or unused wire to avoid incorrect wiring.

Specifications of cable

• UL style 2464, 6c×No.20AWG, ( 80°C 300V )

Identification of wire

• The identification of wire is made by the color and white line printed on the wire
  No.| Color of Insulator

  1| Orange / White
  2| Blue / White
  3| Brown / White
  4| Brown

Note: Use the monitoring device(Safety relay module) provided the capability to detect a cross short circuit. The insulation of the cable has to withstand environmental influences. If a control device other than the one shown in the draft is used, the used control device has to be equipped with a cross short circuit monitor.
