It may cause a breakdown or an consider degrees of the danger and use safety relays, since welded or sticking accident. contacts of standard relays may invalidate the functions of the safety switch. Operation Precautions - for all series • Regardless of door types, do not use the safety switch as a door stop. Install • Prevent foreign objects such as dust and liquids from entering the switch a mechanical door stop at the end of the door to protect the safety switch while connecting conduit or wiring. against excessive force. • If the operating atmosphere is contaminated, use a protective cover to • Do not apply excessive shock to the switch when opening or closing the door. prevent the entry of foreign objects into the switch through the actuator entry slots. 2 • A shock to the door exceeding 1,000 m/sec (approx. 100G) may cause the contacts of the switch to chatter, and a malfunction of the switch may occur. • Entry of a considerable amount of foreign objects into the switch may affect the mechanism of the switch and cause a breakdown. • For connection of wires, unscrew the cover. Unnecessary loosening of other screws may cause a malfunction of the switch. • Do not store the switches in a dusty, humid, or organic-gas atmosphere. HS5E/HS5B Precautions For Rotating Head Directions Note: Because deviation or dislocation of hinged doors may occur in actual applications, make sure of the correct operation before installation. • The heads of the HS5E/HS5B can be rotated in 90° increments after removing When using the HS9Z-A52 Actuator the 4 screws on the corners of the head. Prevent entry of foreign objects into the switch during removal of the head. Tighten these screws with torque • When the door hinge is on the extension line of the interlock switch surface: designated in the instruction sheet. Improper torque may cause errors. Factory Setting Head can be rotated. Door Hinge Door Hinge • When door hinge is on the extension line of the actuator mounting surface: Door Hinge Door Hinge Minimum Radius of Hinged Doors • When using the interlock switch on hinged doors, refer to the minimum radius of doors shown below. When using on doors with small minimum radius, use the angle adjustable actuator (HS9Z-A55). HS2B Precautions Wire Connection • Cracks or burrs on the conduit entry may deteriorate the housing protection against water. • The HS2B has 3 conduit ports, which are closed as a part of the molded switch housing. • When changing to another conduit port, close the unused opening with an optional plug (Part No. HS9Z-P1). • Make an opening for wire connection by breaking one of the conduit-port knockouts on the switch housing using a screwdriver. • When breaking the conduit port, take care not to damage the contact block or other parts inside the switch.

Caution: After the unlocking operation, put the screw back into the unlocking entry for safety. • Before breaking the knockout, temporarily remove the connector-fi xing lock nut from the switch. • When breaking the knockout, take care not to damage the contact block or other parts inside the switch. • Cracks or burrs on the conduit entry may deteriorate the housing protection. • When changing to the other conduit port, close the unused opening with an optional plug (accessory). Unlock Unlock Plug Screwdriver Type No. HS9Z-P1 Normal Position Manual Unlocking Position Manual Unlocking • Remove the screw located on the unlocking entry at the side of the switch us- ing the key wrench included with the switch. Then insert a small screwdriver into the switch to push the lever inside of the switch toward the indicator until the actuator is unlocked (refer to the diagram on the right). • Insert a small screwdriver into the elliptical hole on the back of the switch, then push the lever inside of the switch toward the indicator until the actuator is unlocked (refer to the diagram on the right). HS1C Precautions • Regardless of door type, do not use the safety switch as a locking device. Install a locking device independently, for example, using a metal latch (also applicable to HS1E). • The safety switch cover can be only removed with the special key wrench supplied with the switch or with the optional screwdriver (also applicable to HS1B and HS1E). • Remove the screw located on the unlocking entry at the side of the switch us- ing the key wrench included with the switch.
