Cause
Cause
Noise is out of the speci-
fied range.
Internal error
Internal error
Systems are different be-
tween emitter and receiver.
Voltage level of interlock
setting input wire (pale pur-
ple) or test input / reset in-
put wire (pink) is unstable.
Safety input 1 wire (gray)
or safety input 2 wire (gray
/ black) is short-circuited.
Output polarity setting wire
(shield) comes down or short-
circuits with other I/O wires.
Output polarity setting wire
(shield) connection of emit-
ter / receiver is incorrect.
Safety input 1 wire (gray) or
safety input 2 wire (gray /
black) is not correctly wired.
Temporal difference of out-
put operation of safety input
1 / 2 is more than 1 sec.
Safety input 1 indicator
(orange) or safety input 2
indicator (orange) blinks.
Specified voltage is not be-
ing supplied.
Muting lamp output wire (red)
short-circuits with 0V or +V.
Muting lamp output short-
circuits with other I/O wires.
Excessive incoming cur-rent
flows in the muting lamp output.
Output polarity setting wire
(shield) and muting lamp
output wire (red) are not
correctly wired.
Output circuit error.

Remedy
Check that the power supply capacity is sufficient. Connect the pow-
er supply correctly.
Set the supply voltage correctly.
Connect the connector securely.
Check the noise status around this device.
If the handy controller SFC-HC (optional) is used, reset the func-
tion.
Contact our office.
Contact our office.
Set the same value to the number of beam channels of emitter
and receiver and the output polarity setting wire (shield).
Wire the interlock setting input wire (pale purple) and test input /
reset input wire (pink) correctly.
Refer to "2-5 Wiring."
Wire the safety input 1 wire (gray) or safety input 2 wire (gray /
black) correctly.
Make sure there is no damage of safety contacting point or safety
sensor.
Wire the output polarity setting wire (shield) correctly.
(0V: PNP output, +V: NPN output)
Wire the output polarity setting wire (shield) of the receiver cor-
rectly.
Wire the safety input 1 wire (gray) and the safety input 2 wire (gray
/ black) correctly.
Refer to "2-5 Wiring" or "3-4 Safety Input Function."
Make temporal difference between output operation of safety input
1 and 2 less than 1 sec.
Check the wiring status, supply voltage, and power supply capac-
ity.
Wire the muting lamp output wire (red) correctly.
Refer to "2-5 Wiring."
Current value should be within the specified muting lamp output.
Wire the output polarity setting wire (shield) correctly.
(0V: PNP output, +V: NPN output)
Wire the muting lamp output wire (red) to +V.
Refer to "2-5 Wiring."
Output circuit is damaged. Replace this device.
