Contact Operation
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 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. Do not attach the key to the switch intentionally (the key is designed to
fall off when the operator's hand is off he key).
• Unlocking by pushing the plate inside the safety switch must be perfomed in
emergency only. After unlocking, make sure to tighten the M4 screw to the
tightening torque of 0.3 to 0.5 N•m. Do not apply excessive force to the M4 screw.
Otherwise the safety switch is damaged. Make sure that all screws are installed,
otherwise the waterproof capability is lost.

• When the actuator is locked or unlocked, the NC lock monitor contacts and NO
unlock monitor contacts cause bouncing. When designing a control circuit, take the
bouncing into consideration (reference values: 20ms).
• Solenoid has polarity. Be sure to wire correctly and do not apply reverse voltage
otherwise the solenoid will be damaged. Do not apply voltage that exceed the rated
voltage, otherwise the solenoid will be burnt out.
• Do not fasten or loosen the conduit at the bottom of he safety switch.
• When wiring, make sure that liquid such as water and oil does not intrude from the
end of the cable.
• When bending the cable during wiring, secure the
cable radius of 30mm at the minimum. Do not
apply an excessive shock, such as tensile and
compressing force, to the connection part of the
cabel and switch.
• Use the proprietary actuators only. Other actua-
tors will cause damage to the switch.
• 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.
For Manual Unlocking
• Spring lock type : The HS6E allows manual unlocking of the actuator to precheck
proper door operation before wiring or turning power on, as well as for emergency
use such as a power failure.
• Solenoid lock type : If the actuator is not unlocked although the solenoid is deener-
gized, the actuator can be unlocked manually.
Manual Unlocking Method
• When using the manual unlock key :
To change the normal position to the manual unlocking position as shown above,
turn the key fully (90 degrees) using the propietary key supplied 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.
Note: When manually unlocked, the switch will keep the main circuit disconnected
and the door unlocked.
• When unlocking by pushing he plate insaide the safety
switch :
Remove the screw at the side of the safety switch and
insert a small screwdriver. Push the plate inside the
safety switch toward the LED pilot light using a small
screwdriver until the actuator is unlocked. See the
figure on the right.
CAUTION
• HS6E 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.
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. When a higher load works on the lock portion of the
safety switch, the actuator may not unlock.
• 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.
• 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 he 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.

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.
