Troubleshooting of receiver
<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.

Remedy
[Digital error indicator: ]
Setting data error of this device
Series connection is in-correct.
Check that the cable for series connection does not short-circuit, or is con-
nected to the correct position (emitter for emitter, receiver for receivers).
Incase the handy controller
SFB-HC
(optional) is applied, reset the function.
Noise is out of the specified range.
Check the noise status around this device.
If the handy controller
SFB-HC
(optional) is used, reset the function.
Internal error
Contact our office.
[Digital error indicator: ]
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: ]
Series connection error
The serial signal short-circuits or comes
down.
Check if the end cap has been fitted properly.
Check that the cable for series connection does not short-circuit, or is con-
nected to the correct position (emitter for emitter, receiver for receiver). Check
the error contents of the device connected by the cable for series connection.
Any of the main / sub sensor is in error.
[Digital error indicator: ]
No. of total units / No. of total beam chan-
nels error
No. of total units / No. of total beam
channels is out of the specified range.
Set the condition of the series connection within the specification.
[Digital error indicator: ]
Extraneous light error
Extraneous light is entering or light from
other model is entering.
When the power is ON, prevent any extraneous light from entering
the receiver.
[Digital error indicato: , ]
Control output (OSSD 1 / 2) data error
Control output 1 (OSSD 1) wire (black)
or control output 2 (OSSD 2) wire
(white) is short-circuited.
Wire the control output 1 (OSSD 1) wire (black) and the control
output 2 (OSSD 2) wire (white) correctly.
Current value should be within the specified the control output
1 (OSSD 1) wire (black) and the control output 2 (OSSD 2) wire
(white).
Control output 1 (OSSD 1) wire (black)
or control output 2 (OSSD 2) wire
(white) is wired or is wired with other I/O
wires.
Excessive incoming current flows in con
-
trol output 1 (OSSD 1) wire (black) or
control output 2 (OSSD 2) wire (white).
Output polarity setting wire (shield), con-
trol output 1 (OSSD 1) wire (black) or
control output 2 (OSSD 2) wire (white) is
not correctly wired.
Wire the output polarity setting wire (shield) correctly.
(0V: PNP output, +V: NPN output)
Wire the control output 1 (OSSD 1) wire (black) and the control
output 2 (OSSD 2) wire (white) correctly. (0V: PNP output, +V:
NPN output)
Output circuit error
Output circuit is damaged. Replace this device.
