Troubleshooting of emitter
<All indicators are OFF>
Cause Remedy
Power is not being supplied.
Check that the power supply capacity is sufficient. Connect the
power supply correctly.
Supply voltage is out of the specified
range.
Set the supply voltage correctly.
Connector is not connected securely. Connect the connector securely.
<Fault indicator (yellow) lights up or blinks>
Cause Remedy
Digital error indicator:
In case of
SF4C-F15□,
Error indicator (yellow) lights up.
Setting data error of this device
Noise is out of the specied range.
Check the noise status around this device.
If the handy controller
SFC-HC
(optional) is used, reset the function.
Internal error Contact our ofce.
Digital error indicator:
In case of
SF4C-F15
□,
Error indicator (yellow) blinks 1 time.
Number of beam channel error
Internal error Contact our ofce.
Digital error indicator:
In case of
SF4C-F15
□,
Error indicator (yellow) blinks 3 times.
System error between emitter and receiver
Systems are different between emitter
and receiver.
Set the same value to the number of beam channels of emitter and
receiver and the output polarity setting wire (shield).
Digital error indicator:
In case of
SF4C-F15
□,
Error indicator (yellow) blinks 4 times.
Interlock setting error
Voltage level of interlock setting input
wire (pale purple) or test input / reset
input wire (pink) is unstable.
Wire the interlock setting input wire (pale purple) and test input /
reset input wire (pink) correctly.
Digital error indicator:
In case of
SF4C-F15
□,
Error indicator (yellow) blinks 5 times.
Safety input crossover short-circuit
Safety input 1 wire (gray) or safety input
2 wire (gray / black) is short-circuited.
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.
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) con-
nection 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.
