Cause
[Digital error indicator: ]
Wiring error of the output polarity setting
wire (shield)
Output polarity setting wire (shield)
comes down or short-circuits with o her
I/O wires. Output polarity setting wire
(shield) connection of emitter / receiver
is incorrect.
[Digital error indicator: ]
External device error
When using safety relay.
Relay contact is welded.
Response time of the relay is slow.
Contacting point "b" of he relay is not
wired.
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.
Auxiliary output is not correctly oper-
ated.
Bottom cap cables are adversely con-
nected between emitter and receiver.
[Digital error indicator: ]
Effect from noise or failure of internal circuit
Affected by noise.
Internal circuit is broken down.
<Digital error indicator " " lights up>
Cause
Synchronization + wire (orange) or syn-
chroniza ion - wire (orange / black) error.
Synchronization + wire (orange) or syn-
chronization - wire (orange / black) is
short-circuited or disconnected.
Emitter error.
<All beam-axis adjustment indicators (red) light up>
Cause
The beam channel with its fixed blanking
function set into valid receives light.
<OSSD indicator remains lit in red (light is not received)>
Cause
The beam channels are not correctly
aligned.
<Reference>
About counting blinks of the error indicator, count blinks from 2 seconds of no blinking.
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.
Replace the relay.
Replace the relay with proper response time.
Setting by the handy controller SE9Z-HC (optional) is also possible.
Wire correctly to the relay.
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 SE9Z-HC (op ional).
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
SE9Z-HC (op ional).
Check the connec ing locations of he bottom cap cables.
Check the noise status around this device.
When the synchronization cable is extended with a cable other than
exclusive cable, use a 0.2mm
If this device still does not work, confirm number of blinks of he er-
ror indicator and call to our local office.
Connect he synchronization + wire (orange) and synchronization -
wire (orange / black) properly.
Check the operation of the emitter side.
Turn ON the power supply after checking the installation status.
Align the beam channels.
Align the top / bottom direction of the beam channel between emit-
ter and receiver.
