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 he 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 operator's 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
opera ion.
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 opera ing.
• Use hand to press the button, and do not use a tool. Do not apply excessive force
to the rear unlock button.
• 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.
