Cause
[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.
Receiver error.
<Emission halt input indicator (orange) lights up>
Cause
The device is in the emission halt input
condi ion. (Device error or interlock setting
error)
Error indicator (yellow) lights up or
blinks.
Emission halt input / reset input wire
(pink) is open when selecting auto reset.
Emission halt input / reset input wire
(pink) is connected to 0V or +V when
selecting manual reset.
<All beam-axis adjustment indicators (red) light up>
Cause
The beam channel with its fixed blanking
function set into valid receives light.
<Operation indicator remains lit in red (light is not received)>
Cause
The beam channels are not correctly
aligned.
Sensing range is shortened because of
the emission amount control function.
<Reference>
About counting blinks of the error indicator, count blinks from 2 seconds of no blinking.
Check the noise status around this device.
When he synchronization cable is extended with a cable other
han exclusive cable, use a 0.2mm
cable.
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 receiver side.
Check the error contents of the digital error indicator.
Wire the emission halt input / reset input wire (pink) to 0V or +V.
Open the emission halt input / reset input wire (pink).
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.
Reset to factory default (CLR) by the handy con-troller SE9Z-HC
(optional).
