---|---
HS9Z-A11T| 5 3.8mm
HS9Z-Al2T| 5 3.8mm

For Type HS9Z-A11T/Al2T actuator

  • When there is a displacement of safety switch and actuateor, the actuator may hit the entry slot of safety switch hardly, thus damaging the entry slot and acutuator. The rubber cushions on the HS9Z actuator prevent the actuator from damaging the entry slot 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 enviroment and conditions. Immediately replace the deformed or cracked rubber cushions with new ones.

CAUTION
7 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.
8: When rubber cushions (and spacers) are not used, use M6 screws and tighten to a torque of 4.5 to 5.5 N.m.

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.

IDEC HS1T Interlock Switch 4-Contact Spring Lock 10

(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.
