HS5L Interlock Switches with Solenoid

Instructions

Manual Unlocking

Spring lock

The spring lock interlock switch allows manual unlocking of the

actuator to precheck proper door movement before wiring or

turning power on, as well as for emergency use such as a power

failure.

Solenoid lock

The solenoid interlock switch does not unlock even when the

solenoid is de-energized. However, the interlock switch can be

unlocked manually in emergency cases.

LOCK

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

operation failures (when manually unlocked, the interlock switch

will keep the main circuit disconnected and the door unlocked).

Do not apply excessive force to the manual unlock, otherwise the

manual unlock will become damaged. Do not leave the manual

unlock key attached to the interlock switch during operation.

This is dangerous because the interlock switch can always be

unlocked while the machine is in operation.

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 machine

stops, and the function of interlock switch with solenoid is lost.

Push Rod

After installing the interlock switch on the

panel, place the rear unlocking button

(supplied with the switch) on the push

rod on the back of the interlock switch,

and fasten the button using M3 sems

screw (supplied with the switch).

When installing on a mounting frame

thicker than 6mm, use the rear unlocking button kit HS9Z-FL5

(sold separately).

Safety Precautions

After installing the rear unlocking button, apply Loctite to the

screw so that the screw does not become loose. The rod is made

of SUS, the button is made of glass-reinforced PA66 (66 nylon)

and the screw is made of iron. Take the compatibility of the plastic

material and Loctite into consideration.

Installing the Rear

Unlocking Button Kit

1. Install the connecting rod onto the

push rod on the HS5L-L rear

unlocking button interlock switch.

2. A pin is attached to the connecting

rod. Insert the pin into the hole in

the push rod, using pliers.

3. Pull the connecting rod from the hole in the mounting frame,

and turn the button operating pin to the horizontal position.

Safety Precautions

• Ensure that the connecting rod is pulled out completely and it is

horizontal to the interlock switch, otherwise the unlocking button

cannot be installed.

Note: Frame must be supplied by the user.

For the mounting hole layout of interlock switches, see

dimensions on page 18.

4. Install the unlocking button on the connecting rod by fitting the

pin to the grooves on the back of the button, and fasten the

base plate on the mounting frame using the screws.

shown below. Do not install

the kit in incorrect directions,

otherwise malfunction may

occur.

• Do not apply strong force

exceeding 100m/s2 to the

interlock switch while the rear unlocking button is not pressed,

otherwise malfunction may occur.

Unlocking the Manual Lock Using the

Rear Unlocking Button

Use the rear unlocking button when a worker is locked inside

a safety fence (hazard area). (Compliant with escape release

Procedure

• When the rear unlocking button is pressed, the interlock switch

is unlocked and the door can be opened.

• To lock the interlock switch, pull back the button.

• When the button remains pressed, the interlock switch cannot

be locked even if the door is closed, and the main circuit remains

open.

Safety Precautions

• Install the rear unlocking button in the place where only the

operator inside the hazardous area can use it. Do not install the

button in a place where an operator outside the hazardous area

can use it, otherwise the interlock switch can be unlocked during

usual machine operation, causing danger.
