TROUBLESHOOTING
●
The number of times the fault indicator (yellow) blinks indicates the
type of error state, as follows.
Blinking
Description of error
Cause / Remedy
2 times
Internal relay contact is
weld
The contact was weld due to the lifetime of the
relay.
Replace this product by new one.
3 times

or more
I n f l u e n c e o f n o i s e /
power supply or internal
circuit failure
Check the noise environment.
Check the wiring, power supply voltage and
voltage capacity.
●
Make sure that this product and the light curtain are connected to the
common power supply.
●
When the sensor doesn't operate properly even if the remedies de-
scribed above are taken, contact our office.
●
Interval of blinking for the fault indicator (yellow) is approx. 0.6 sec.
Check the number of times the indicator blinks for approx. 2 sec. from
the indicator “OFF” period.
WARNING
Install a RESET switch in palace where it is possible to see all over the
dangerous zone and outside of the zone.
<Manual reset>
• In case of the manual reset, configure the back check circuit between X1
and X2. If it is not necessary to check KA and KB, short-circuit KA and KB.
•
Do not connect anything to X3.
•
The unit operates by the trailing operation of the external reset button.
•
Two or more units cannot be controlled by an external reset button.
Prepare the external reset button for unit by unit.

<Auto reset>
• In case of the auto reset, configure the back check circuit between X1 and X3.
If it is not necessary to check KA and KB, short-circuit between X1 and X3.
•
Do not connect anything to X2.
•
Avoid auto-reset of the system after emergency stop by using the other
control circuit. (IEC / EN 60204-1 part 9.2.5.4.2 and 10.8.3)

MOUNTING TERMINAL BLOCK
●
When connecting to the terminal
block, insert a solid wire or twisted
wire (lead wire) with a ferrule (sleeve)
terminal (please arrange separately)
into the hole till it stops as shown in
the figure right. The wire is locked
when it is properly inserted. However,
do not to pull the wire with excessive
force, as this can cause a cable break.
●
When connecting the twisted wire (lead wire)
without a ferrule (sleeve) terminal, insert the
wire to the innermost of the connecting hole
while pressing the release button.
●
When releasing the solid wire or the
twisted wire (lead wire), pull the wire
while pressing the release button.
Lead wire

button
Solid wire or twisted
wire (lead wire) inlet

(Please arrange separately)
●
The following solid wire and twisted wire (lead wire) are recommended.
Solid wire: ø0.4 to ø1.2mm (AWG 26 to 16)
Twisted wire (lead wire): 0.2 to 1.25mm

The power supply unit of this equipment adopts the electronic fuse
which do not require any replacement.
●
When the electronic fuse is operated, turn OFF the power supply, and remove
the cause of overcurrent before restarting the power supply for resetting.
●
The electronic fuse is not suitable to use in which the equipment is
operated continuously or daily. Note that operating the equipment con-
tinuously may be unable to satisfy the specifications.

FUNCTIONS
●
Trailing edge switching function
•
This function is to accept the input when the reset switch is pressed (con-
tact “close”) and then released (contact “open”) at the manual start setting.
An unexpected start-up due to the welded reset switch can be avoided.
