Rotating the Head

The head can be rotated by removing the four screws from the

corners of the head and reinstalling the head in the desired

orientation. However, when changing the mounting direction of the

head after wiring, turn the manual lock release to the “UNLOCK”

position using the enclosed manual lock release key first. When

reinstalling the head, make sure that no foreign object enters

the interlock switch. Tighten the screws tightly, without leaving a

space between the head and body, otherwise the interlock switch

may malfunction.

(Recommended tightening torque: 0.9 to 1.1 N·m)

Head Removal Detection Function

• Solenoid locks interlock switches are not equipped with the head

removal detection function.

• The head removal detection function is available only on spring

lock interlock switches with circuits VB, VD, and DD having two

or more lock monitor circuits. Removing the head will result in

disparity (41-42: OFF, 51-52: ON). Note that this function cannot

be detected with other models.

• Only the lock monitor circuit 41-42 turns off (open) when the

head is removed, such as when the head is rotated. The other

monitor circuit 51-52 turns ON (close). Be sure to connect the

lock monitor circuit (41-42) to a safety circuit.

Spring Loaded Actuator

• When using the actuator, be careful of protruding ends.

• Regardless of door types, do not use the HS9Z-BA5 actuator as

a door lock or a door stop.

• When an operator enters the hazardous zone, take safety

measures such as using a HS9Z-PH5 padlock hasp so that the

operator is not trapped inside and the machine cannot start by

mistake.

• Use the actuator only on sliding

doors. Do not use on hinged doors.

• As shown in the figure on the right,

do not insert the sliding actuator from

below. The actuator may fall out due

to shocks.

• The HS9Z-BA5 actuator can only be

used for HS5L interlock switches. Do

not use the HS9Z-BA5 actuator for

other products.

• Do not modify or disassemble the

actuator.

Installation (when installation reference is 0.8mm)

• The actuator protrudes out when the actuator is not inserted

(door is open) as shown in 1. in the drawing.

• The mounting reference position can be set to 0.8mm when the

actuator is fully inserted and the actuator protrudes up to the

0.8mm line.

Adjustment

Adjustment Procedure

1. Make a hole at A or C.

2. Fasten temporarily with screws, and check the actuator

position.

3. Make a hole at B and fix the actuator using a screw or a rivet.

• 3.3mm line

The mounting reference position is where the door is fully closed,

and there is a 0.8mm space between the safety switch and

HS9Z-BA5, but can be adjusted up to the 3.3mm line.

The actuator is most securely locked when the mounting

reference position is at the 0.8mm line. However, adjust between

0.8 to 3.3mm if the safety switch is mounted on a door where the

space might become smaller.

• Lock limit line

When a door opens by bouncing, if the

lock limit line is outside of the edge of the

interlock switch, the force of the bounce

may be too large so that the door may not

lock.

Safety Precautions

• The maximum gap of the door that can be locked is 16mm.

(When mounting reference is a the 0.8mm line)

• If the safety distance and minimum gap does not satisfy the

requirements of ISO13857, make the gap smaller by overlapping

the doors or by providing sufficient distance from the hazardous

source.

• The operating characteristics may change when the actuator is

used with the HS5L. Check the operating characteristics before

use.
