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 circuit
that 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 endan-
gered in the event of a malfunction of the PLC .
•
Do not disassemble or modify the interlock switch, other-
wise a breakdown or an accident may occur .
•
Do not install the actuator in a location where the human
body may come in contact . Otherwise injury may occur .
Instructions
•
Regardless of door types, do not use the interlock switch
as a door stop . Install a mechanical door stop at the end of
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/s
2
may cause damage to the interlock
switch .
•
If the operating atmosphere is contaminated, use a pro-
tective 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 a break-
down .
•
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, or
organic-gas atmosphere .
•
Use proprietary actuators only . Using other actuators may
damage the interlock switch .
•
Do not modify the actuator, otherwise it will damage the
interlock switch .
•
Do not open the lid of the interlock switch . Loosening the
screws may damage the interlock switch .
•
The actuator retention force is 1,400N . Do not apply a load
higher than the rated value . When a higher load is ex-
pected, provide an additional system consisting of another
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 en-
ters the slot on the interlock switch, make sure that exces-
sive 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 shown
in the figure below . Otherwise, the key may fall off due to
shock .
Incorrect Orientation
Minimum Radius of Hinged Door
When using the interlock switch for a hinged door, refer to
the 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 in actual
applications, make sure of the correct operation before installation .
