[Digital error indicator: ]
External device error
When using
safety relay
Relay contact
is welded.
Replace the relay.
R e s p o n s e
t i m e o f t h e
relay is slow.
Replace the relay with proper response time.
Setting by the handy controller (
SFB-HC
) (op-
tional) is also possible.
Refer to “
3-6 External Device Monitor Func
-
tion
.”
C o n t a c t i n g
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 moni-
tor input 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 “in-
valid” using the handy controller (
SFB-HC
) (op-
tional).
A u x i l i a r y
output is not
correctly op-
erated.
Check if the auxiliary output wire (yellow-green /
black) is disconnected or short-circuited.
Reset to factory default (mode 0) by the handy
controller (
SFB-HC
) (optional).
Bottom cap cables are ad-
versely connected between
emitter and receiver.
Check the connecting locations of the bottom cap
cables.
[Digital error indicator: ]
Effect from noise / power
supply or failure of internal
circuit
Affected by noise / power
supply.
Internal circuit is broken
down.
Check the noise status around this device.
Check the wiring status, supply voltage, and
power supply capacity.
When the synchroni wire (orange) and
synchronization - wire (orange / black) is extend-
ed 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, confirm number
of blinks of the error indicator and call to our local
office.
<Digital error indicator “ ” lights up>
Cause
Remedy
Synchroni wire (orange) or synchronization - wire
(orange / black) error.
Synchroni wire (orange) or synchronization - wire
(orange / black) comes down or short-circuits.
Connect synchroni wire (orange) or syn-
chronization - wire (orange / black) properly.
Refer to “
2-5 Wiring
.”
Emitter error
Check the operation of the emitter side.
<All beam-axis adjustment indicators (red) light up>
Cause
Remedy
The beam channel with its fixed blanking function set into
valid receives light.
Turn ON the power supply after checking the in-
stallation status.
<OSSD indicator remains lit in red (light is not received)>
Cause
Remedy
The beam channels are not correctly aligned.
Align the beam channels.
Refer to “
2-6 Adjustment
.”
Align the top / bottom direction of the beam chan-
nel between emitter and receiver.
If the device does not work normally after checking the items above, please consult Panasonic
Industrial Devices SUNX.
About counting blinks of the error indicator, count blinks from 2 seconds of no blinking.
