Cause
Digital error indicator:
In case of SF4C-F15□,
Error indicator (yellow) blinks 7 times.
Safety input error
Safety input 1 wire (gray) or safety in-
put 2 wire (gray / black) is not correctly
wired.
Temporal difference of output operation
of safety input 1 / 2 is more than 1 sec.
Safety input 1 indicator (orange)
or safety input 2 indicator (orange)
blinks.
Digital error indicator:
In case of SF4C-F15□,
Error indicator (yellow) blinks 8 times.
Supply voltage error
Specified voltage is not being supplied.
Digital error ind3icator:
In case of SF4C-F15□,
Error indicator (yellow) blinks 9 times.
Muting lamp error
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.
Digital error indicator:
In case of SF4C-F15□,
Error indicator (yellow) blinks more
than 10 times.
Effect from noise or failure of internal circuit
Affected by noise.
Internal circuit is broken down.
Digital error indicator:
In case of SF4C-F15□,
Error indicator (yellow) blinks 31 times.
Receiver error
Receiver is in lockout state.
<Digital error indicator " " lights up (Except SF4C-F15□)>
Cause
Synchronization + wire (orange) or syn-
chronization - wire (orange / black) error.
Synchronization + wire (orange) or syn-
chronization - wire (orange / black) is
short-circuited or disconnected.
Receiver error.

Wire the safety input 1 wire (gray) and the safety input 2 wire (gray
/ black) correctly.
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 capacity.
Wire the muting lamp output wire (red) correctly.
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.
Output circuit is damaged. Replace this device.
Check the noise status around this device.
When the synchronization + wire (orange) and synchronization -
wire (orange / black) is extended with a cable other than exclusive
2
cable, use a 0.2mm or more shielded twisted pair cable.
If this device still does not work, confirm number of blinks of the er-
ror indicator and call to our local office.
Check an digital error indicator (red) of receiver.
Connect the synchronization + wire (orange) and synchronization -
wire (orange / black) properly.
Check the operation of the receiver side.
