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.
