HS5E-K

HS5E-K Interlock Switches with Key
Head Removal Detection Circuitry (patented)
Head removal detection circuitry is employed in the HS5E-K. With this innovative function, the monitor circuit (41-42) turns off
when the head is removed from the switch, such as when removing the head to change the head direction (applicable with allmodels of HS5E-K).
With the head installed on the switch, monitor circuits 41-42 and 51-52 operate in synchronization while the key locks/unlocks
the actuator. When the head is removed, 41-42 turns off and 51-52 turns on. This disagreement is detected by the head removal
detection function.

Hazards of the system and robot are isolated by the safety guard. When a worker needs to work inside the hazardous
area for maintenance, the worker stops the machine using the key to change modes (1), unlock the guard using thekey, then remove the key to bring inside the safety guard (2). The worker can switch operation modes and unlock thesafety guard using a single key. Furthermore, when the key is taken inside the hazardous area, the guard cannot belocked and the system cannot be turned on. This enables the worker to work safely in the hazardous area.

HS5E-K Interlock Switches with Key
Safety Precautions• In order to avoid electric shock or fire, turn the power
off before installation, removal, wire connection, maintenance, or inspection of the interlock switch.
• If relays are used in the circuit between the interlock
switch and the load, consider the danger and use safety
relays, since welding or sticking contacts of standard
relays may invalidate the functions of the interlock switch.
Perform a risk assessment and establish a safety circuitthat satisfies the requirement of the safety category.

• Do not place a PLC in the circuit between the interlock
switch and the load. Safety and security can be endangered in the event of a malfunction of the PLC.
• Do not disassemble or modify the interlock switch, otherwise a breakdown or an accident may occur.
• Do not install the actuator in a location where the humanbody may come in contact. Otherwise injury may occur.

Instructions
Minimum Radius of Hinged Door
When using the interlock switch for a hinged door, refer tothe minimum radius of doors shown below. For doors
with a small minimum radius, use angle adjustable
actuators (HS9Z-A53 or HS9Z-A55) .
Note: Because deviation or dislocation of a hinged door may occur inactual applications, make sure of the correct operation before
installation.

nte rsCe enteC• Regardless of door types, do not use the interlock switch
as a door stop. Install a mechanical door stop at the endof the door to protect the interlock switch against excessive force.
• Do not apply excessive shock to the interlock switch
when opening or closing the door. A shock to the interlock switch exceeding 1,000 m/s2 may cause damage tothe interlock switch.
• If the operating atmosphere is contaminated, use aprotective cover to prevent the entry of foreign objects
into the interlock switch through the actuator entry slots.
Entry of foreign objects into the interlock switch may affect the mechanism of the interlock switch and cause abreakdown.
• Using the slot plugs supplied with the interlock switch,plug the unused actuator entry slots.
• Do not store the interlock switches in a dusty, humid, ororganic-gas atmosphere.
• Use proprietary actuators only. Using other actuators may
damage the interlock switch.
• Do not modify the actuator, otherwise it will damage theinterlock switch.
• Do not open the lid of the interlock switch. Loosening thescrews may damage the interlock switch.
• The actuator retention force is 1,400N. Do not apply aload higher than the rated value. When a higher load is
expected, provide an additional system consisting ofanother interlock switch without lock (such as the HS5D/
HS5B interlock switch) or a sensor to detect the door
opening and stop the machine.
• Regardless of door types, do not use the interlock switch
as a door lock. Install a separate lock using a latch or
take other measures.
• Although the HS9Z-A51A and HS9Z-A52A actuators (w/rubber bushings) alleviate the shock when the actuator
enters the slot on the interlock switch, make sure that
excessive shock is not applied. If the rubber bushings
become deformed or cracked, replace with new ones.
• Do not mount the interlock switch facing down as shownin the figure below. Otherwise, the key may fall off due toshock.

Instructions
Actuator Angle Adjustment (vertical/horizontal)• Using the angle adjustment screw, the actuator angle canbe adjusted (refer to the dimensional drawing on page55). Adjustable angle: 0 to 20°• The larger the adjusted angle of the actuator, the smaller
the applicable radius of the door opening. After installingthe actuator, open the door. Then adjust the actuator sothat its edge can be inserted properly into the actuator
entry slot of the interlock switch.
• After adjusting the actuator angle, apply Loctite to theadjustment screw so that the screw will not move.

Head Removal Detection Circuitry• Only the lock monitor circuit 41-42 turns off (open) when
the head is removed, such as when the head is rotated.
The other monitor circuit 51-52 turns ON (close). Be sure
to connect the lock monitor circuit (41-42) to a safety
circuit.
• When connecting the HS5E-K to a safety circuit, connect
the door monitor circuits (11-12) and the lock monitor
circuits (41- 42) in series. (GS-ET-19)• When rotating the head, make sure that the interlock
switch is not wired or that the key position is in the UNLOCK position.
