For Manual Unlocking

Spring lock type

The HS1L allows manual unlocking of the actuator to pre-check

proper door movement before wiring or turning power on, as

well as for emergency use such as in the case of a power fail-

ure.

Solenoid lock type

The solenoid lock type interlock switch normally does not need

to be manually unlocked. However, only when the interlock

switch would not release the actuator even though the solenoid

is de-energized, the interlock switch can be unlocked manually.

Unlock the interlock switch manually only when the solenoid is

de-energized. Do not unlock the interlock switch manually when

the solenoid is energized.

Using manual unlock key

When locking or unlocking the interlock switch manually, turn

•

the key fully using the manual unlock key supplied with the

interlock switch.

Using the interlock switch with the key not fully turned (less

•

than 90°) may cause damage to the interlock switch or op-

eration failure. When manually unlocked, the interlock switch

will keep the main circuit disconnected and the door unlocked.

Main circuit and lock monitor circuit remain open.

Do not leave the manual unlock key attached to the interlock

•

switch during operation. This is dangerous and does not satis-

fy safety standard requirements, because the interlock switch

can always be unlocked while the machine is in operation.

Unlocking from the back of interlock switch

•

Insert the tip of a small screwdriver into the oblong hole on the

back of the interlock switch, and tilt toward the center of the

switch until the actuator is unlocked.

Note: Provide a hole on the mounting panel for unlocking from

the back. When making a hole in the panel, take water-

proof characteristics into consideration.

Safety Precautions

Before manually unlocking the interlock switch, make sure that

the machine has come to a complete stop. Manual unlocking

during operation may unlock the interlock switch before the ma-

chine stops, and the function of interlock switch with solenoid

is lost.

On the solenoid lock type, manual unlocking is provided for the

situation where the switch cannot be unlocked even though the

solenoid has turned off. Do not attempt manual unlocking while

the solenoid is energized.
