Cause Remedy
Digital error indicator:
In case of
SF4C-F15
□,
Error indicator (yellow) blinks 6 times.
Wiring error of the output polarity setting
wire (shield)
Output polarity setting wire (shield)
comes down or short-circuits with other
I/O wires. Output polarity setting wire
(shield) connection of emitter / receiver
is incorrect.
Wire the output polarity setting wire (shield) correctly.
(0V: PNP output, +V: NPN output)
Wire the output polarity setting wire (shield) of the receiver correctly.
Digital error indicator:
In case of
SF4C-F15
□,
Error indicator (yellow) blinks 7 times.
External device error
When using safety relay.
Relay contact is welded. Replace the relay.
Response time of the relay is slow.
Replace the relay with proper response time.
Setting by the handy controller
SFC-HC
(optional) is also possible.
Contacting point “b” of the relay is not
wired.
Wire correctly to the relay.
When setting the external device moni-
tor function to “invalid.”
Auxiliary output wire (yellow-green /
black) and external device monitor in-
put wire (yellow-green) are not wired.
Connect the auxiliary output wire (yellow-green / black) and the
external device monitor input wire (yellow-green).
Set the external device monitor function to “invalid” by using the
handy controller
SFC-HC
(optional).
Auxiliary output is not correctly oper-
ated.
Check if the auxiliary output wire (yellow-green / black) is discon-
nected or short-circuited.
Reset to factory default (mode 0) by using the handy controller
SFC-HC
(optional).
Digital error indicator:
In case of
SF4C-F15
□,
Error indicator (yellow) blinks 8 times.
Supply voltage error
Specied voltage is not being supplied. Check the wiring status, supply voltage and power supply capacity.
Digital error indicator:
In case of
SF4C-F15
□,
Error indicator (yellow) blinks 31 times.
Emitter error
Emitter is in lockout state. Check a digital error indicator (red) of emitter.
Digital error indicator:
In case of
SF4C-F15
□, Error indicator
(yellow) blinks more than 10 times.
Effect from noise or failure of internal cir-
cuit
Affected by noise.
Internal circuit is broken down.
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
cable, use a 0.2mm
2
or more shielded twisted pair cable.
If this device still does not work, conrm number of blinks of the er-
ror indicator and call to our local ofce.
<Digital error indicator “ ” lights up (Except SF4C-F15□)>
Cause Remedy
Synchronization + wire (orange) or syn-
chronization - wire (orange / black) error.
Synchronization + wire (orange) or syn-
chronization - wire (orange / black) is
short-circuited or disconnected.
Connect the synchronization + wire (orange) and synchronization -
wire (orange / black) properly.
Emitter error. Check the operation of the emitter side.
