Troubleshooting
If the GL-R is not functioning normally, check the GL-R indicators first.
The GL-R is in an error condition under the following situations.
•
The center indicators blink in red.
•
The 7-segment display indicates "".
If the GL-R does not demonstrate the above situations, the GL-R is not in an error condition.
If the GL-R is in an error condition
*1 All indicators on the transmitter may turn OFF.
*2 This error occurs only when the muting lamp error is configured to cause error condition by using the
configuration software.

Wiring error
The end cover on the
receiver is not connected.
Check that the end cover is installed on the receiver
correctly.
The unit connection cable
is connected to the upper
part of the GL-R.
Connect the unit connection cable to the lower part of
the GL-R.
Transmitter and receiver
are not the same model.
Check that all transmitter and receiver models are
paired correctly.
When the GL-R operates in wire synchronization system
The synchronization wire is
not wired correctly or
disconnected.
Check the wiring of the synchronization wire.
"Cable color and pin position" (page 6)
When the GL-R operates in one-line system
The unit connection cable
is connected to the
transmitter.
•
Connect the unit connection cable to the receiver.
•
Do not connect the unit connection cable to the
transmitter.
The series connection
cable is connected to the
lower part of the GL-R.
Connect the series connection cable to the upper part
of the transmitter and receiver.
When the GL-R is in series connection.
The sub unit is not
connected correctly.
•
Check for the direction of the sub unit installation.
•
Check whether the receiver of sub unit is connected
to the transmitter of main unit.
•
Check whether the total number of beam axes is
more than 240.
The sub unit is broken.
Check that the sub unit operates correctly when not in
series connection.
When the error is cleared by restarting the GL-R.
The synchronization wire is
affected by external noise.
Check for noise source (inverter, servomotor, etc.)
around the GL-R installation location and cables.

Setting switch error
The configuration of the
setting switch is out of
specification.
Check the configuration of the setting switch.
The setting switch is
configured to something
other than Channel 0 in
wire synchronization
system.
Configuration error
The configuration of the
setting switch overlaps the
configuration uploaded
from the configuration
software.
Modify the configuration of the setting switch or modify
the configuration by the configuration software.
The unit configuration is
different from the
configuration uploaded
from the software.
Check the model name of main unit and sub unit and
whether the unit configuration from the software is
identical to the actual unit configuration.
The upload of configuration
has not been completed
correctly when using the
configuration software.
Upload the configuration again.
Interlock error
Interlock mode selection
input or reset input are
wired incorrectly.
Rewire the interlock mode selection input or reset input
correctly.
EDM error
EDM input is not
connected correctly.
•
If EDM function is needed, rewire the EDM correctly.
•
If EDM function is not needed, rewire the EDM and
AUX correctly or deactivate the EDM function by the
configuration software.
There is a welded contact
on the external device.
Replace the external device.
Receiver error
The receiver is affected by
ambient light.
Shield the receiver from ambient light.
Transmitter error
The transmitter is broken.
Replace the transmitter.
When the error is cleared by restarting the GL-R.
The transmitter is affected
by external noise.
Check for a noise source (inverter, servomotor, etc.)
around the GL-R installation location and cables.
OSSD1 error
OSSD2 error
When the error is cleared by restarting the GL-R.
OSSD is affected by
external noise.
Check for a noise source (inverter, servomotor, etc.)
around the GL-R installation location and cables.
There is a voltage surge
affecting the OSSD due to
an inductive load.
When the load is inductive such as relay, use a load
with a surge absorption device.
The power supply voltage
has fallen continuously or
experienced a sudden
drop.
Take measures by replacing the power supply,
increasing the power capacity, or dedicating the power
supply to the GL-R.
When the error is not cleared by restarting the GL-R.
•
OSSD is short-circuited
to 0 V or 24 V of power
supply.
•
OSSDs are short-
circuited to each other.
•
OSSD is short-circuited
to other wires.
Rewire the OSSD correctly.
Too much current is
flowing through the OSSD.
Check that the load does not consume more current
than the OSSD can handle.
OSSD is broken.
Replace the receiver.
Sub unit error
The sub unit is broken.
Replace the sub unit.
When the error is cleared by restarting the GL-R.
The sub unit or series
cable is affected by
external noise.
Check for a noise source (inverter, servomotor, etc.)
around the GL-R installation location and cables.
Communication error
*1
When the error is cleared by restarting the GL-R.
The synchronization wire is
not wired correctly or is
disconnected.
Check the connection of the synchronization wire.
The synchronization lines
in the cable are affected by
external noise.
Check for a noise source (inverter, servomotor, etc.)
around the GL-R installation location and cables.
The power supply voltage
has fallen continuously or
experienced a sudden
drop.
Take measures by replacing the power supply,
increasing the power capacity, or dedicating the power
supply to the GL-R.
When the error is not cleared by restarting the GL-R.
The synchronization wire is
not connected correctly or
is disconnected.
Check the connection of the synchronization wire.
The connection with the
GL-R in series is broken.
Replace the GL-R unit connected in series.
Muting lamp
disconnection error
*2
The muting lamp is not
connected correctly.
Check the connections.
The muting lamp is broken. Replace the muting lamp.
Muting lamp over
current error
*2
The muting lamp is not
connected correctly.
Check the connections.
Too much power is
consumed by the muting
lamp.
Make sure the muting lamp does not consume more
power than the GL-R can handle.
The muting lamp is broken. Replace the muting lamp.
Synchronization beam
axis error
When the GL-R operates in
optical synchronization
system, the fixed blanking
or muting function is
applied to both the upper
and lower beam axes (for
synchronization control).
•
Do not apply the fixed blanking or muting function to
at least the upper or lower axis.
•
Make the GL-R operate in one-line system or wire
synchronization system.
