TLS Module
Code Error Message Description
Corrective Action
1130 Temperature
Error
The temperature inside the module is
too high.
Turn the power off and confirm that the frame controller’s inlet
and exhaust holes are not blocked. After waiting for some
time, restart the instrument. If the same message continues to
appear, servicing is required.
1131 Update Error
A failure occurred during a software
update.
If the same message continues to appear even after you restart
the instrument, servicing is required.
1133 TEC Temperature
Error
The thermistor detected a temperature
error.
Turn the power off and confirm that the frame controller’s inlet
and exhaust holes are not blocked. After waiting for some
time, restart the instrument. If the same message continues to
appear, servicing is required.
1134 TEC Over Current
Error
The thermistor drive current is
abnormal.
If the same message continues to appear even after you restart
the instrument, servicing is required.
1135 TEC Driver
Temperature
Error
The thermistor driver detected a
temperature error.
If the same message continues to appear even after you restart
the instrument, servicing is required.
1136 LD Over Current
Error
The LD drive current is abnormal.
If the same message continues to appear even after you restart
the instrument, servicing is required.
1137 TLS EL Error
A TLS end limit error occurred.
If the same message continues to appear even after you restart
the instrument, servicing is required.
1138 TLS Initialization
Error
A failure occurred during initialization. If the same message continues to appear even after you restart
the instrument, servicing is required.
1139 TLS WL
Calibration Error
An error occurred during wavelength
calibration.
Leave the optical output turned on for at least 30 minutes to
warm up the instrument. If the same message continues to
appear, restart the instrument. If the same message continues
to appear even after you restart the instrument, servicing is
required.
1135 TEC Driver
Temperature
Error
The thermistor driver detected a
temperature error.
If the same message continues to appear even after you restart
the instrument, servicing is required.
1140 APC PD Feed
Back Error
The photodiode’s automatic power
control is malfunctioning.
If the same message continues to appear even after you restart
the instrument, servicing is required.
1141 Gas Cell PD
Feed Back Error
The wavelength calibration system
that uses the internal gas cell is
malfunctioning.
If the same message continues to appear even after you restart
the instrument, servicing is required.
1151 ATT EL Error
The internal attenuator is
malfunctioning.
If the same message continues to appear even after you restart
the instrument, servicing is required.
1152 ATT Initialization
Error
A failure occurred during the
initialization of the internal attenuator.
If the same message continues to appear even after you restart
the instrument, servicing is required.
1153 OSW Switching
Error
The internal optical switch is
malfunctioning.
If the same message continues to appear even after you restart
the instrument, servicing is required.
1157 Wavelength Over
Error
A wavelength was set that does not
fall within the settable range.
Check the wavelength. Set the wavelength to a value that falls
within the settable range.
1159 LD is inactive
The optical output is not active.
Turn the optical output on.
1160 Temperature Limit
Error
The temperature inside the module is
too high.
Turn the power off and confirm that the frame controller’s inlet
and exhaust holes are not blocked. After waiting for some
time, restart the instrument. If the same message continues to
appear, servicing is required.
1161 Memory Check
Error
The internal memory is malfunctioning. If the same message continues to appear even after you restart
the instrument, servicing is required.
1162 Opt Lock Error
The optical output is locked.
Unlock the optical output.
1163 Sweep Parameter
Error1
The sweep start wavelength is larger
than the sweep stop wavelength.
Check the sweep start wavelength, and set it again.
1164 Sweep Parameter
Error2
The number of sweep steps is 20001
or more in the Swept application.
Set the number of sweep steps to a value less than or equal to
20000.
1165 Sweep Parameter
Error3
The sweep speed is set to a speed at
which sweeps cannot be performed.
Check the sweep speed, and set it again.
