* Press the [MODE] button to remove the error and return to the main screen.
When the judgment value (P.V. value) is “”, all judgment outputs turn OFF (when
set to normally open), the analog voltage output changes to 5.5 V, and the analog
current output changes to 3.0 mA.
"4. Output mode [QWV]" (Page 8)
Displayed Contents and Corrective Actions
When an error is displayed, the judgment output changes to the error state.
"4. Output mode [QWV]" (Page 8)
• The check output functions regardless of the error judgment.
• When [GT%] is displayed, all the judgment outputs and check
outputs will turn OFF.
• When an error other than ['T%] or ['T'] is displayed, the analog
voltage output is 5.5 V and the analog output current is 3.0 mA.

sensor amplifier.
Correctly connect the
receiver.
The sensor head cable connector is
not connected correctly.
Connect the connector
again.
The receiver is broken.
Replace the transmitter
or receiver.
The sensor head cable for the receiver
is broken.
Replace the sensor head
cable.
Transmitter laser
error
The laser in the transmitter is broken.
Replace the transmitter
or receiver.
Transmitter error
The transmitter is not connected to the
sensor amplifier.
Correctly connect the
transmitter.
The sensor head cable connector is
not connected correctly.
Connect the connector
again.
The transmitter is broken.
Replace the transmitter
or receiver.
The sensor head cable for the
transmitter is broken.
Replace the sensor head
cable.
Model mismatch
error
The transmitter and receiver model
(measurement range) do not match.
Use a transmitter and
receiver from the same
model (measurement
range).
Transmitter internal
error
The transmitter is broken.
Replace the transmitter
or receiver.
Overcurrent error
An overcurrent exceeding the
specifications passed to the judgment
output or check output.
• Correct the wiring.
• Check the load and
reduce the current to
within the specified
range.
• Check that the output
wire is not touching
another wire or frame.
EEPROM error
Read/write of the non-volatile memory
(EEPROM) save data failed.
Turn the power on again.
Perform initial reset.
The number of writes to the
non-volatile memory (EEPROM)
exceeded 1,000,000 times.
To save the setting
values when the power is
turned off, replace the
amplifier unit.
If the adjust function or the zero shift function is
used frequently, do not save settings in the
non-volatile memory (EEPROM).
Refer to the IB Series User's Manual for details.
Reference light
registration error 1*
(Light insufficient
error)
The reference light registration (gain
adjustment) cannot be completed
because the amount of received light
is too low.
• Correctly mount the
transmitter and
receiver.
• Adjust the beam axis.
• Clean the sensor
head’s laser
transmitting and
receiving sections.
Reference light
registration error 2*
(Interfering light
error)
The reference light registration (gain
adjustment) cannot be completed
because of interfering light or because
the receiver is receiving the laser
beam of a transmitter connected to an
expansion amplifier unit.
• Make sure that the
interfering light does
not enter the laser
receiver.
• Connect the transmitter
and receiver in
combination to the
same amplifier unit.

Adjust error 1*
(Light insufficient
error)
The adjust function cannot be set
because the amount of received light
is too low.
• Perform reference light
registration (gain
adjustment).
• Adjust the beam axis.
• Clean the laser
transmitter and
receiver sections on
the sensor head.
• Increase the adjust
level.
Adjust error 2*
(Excess light error)
The adjust function cannot be used
because the amount of received light
is too high.
• Perform reference light
registration (gain
adjustment).
• Increase the adjust
level.
Adjust error 3*
(Interfering light
error)
The adjust function cannot be set
because of interfering light or because
the receiver is receiving the laser
beam of a transmitter connected to an
expansion amplifier unit.
• Make sure that the
interfering light does
not enter the laser
receiver.
• Connect the transmitter
and receiver in
combination to the
same amplifier unit.
Communication between amplifiers is
disabled.
Turn the power OFF and
check the connections
between the amplifiers.

(R.V. value)
The internal measurement value (R.V.
value) exceeds the lower limit of the
display range.
• Check the shift target
value setting, and shift
the display again.
"Zero Shift
Function (Shifting the
Internal Measurement
Value)" (Page 7)
• Recheck the settings.
• Perform reference light
registration (gain
adjustment) again.

for the internal
measurement value
(R.V. value)
The internal measurement value (R.V.
value) exceeds the upper limit of the
display range.
The key lock is enabled and button
operations are prohibited.
Unlock the key lock state.
Tuning was attempted when [],
[((((] or [((((] was displayed.
Perform tuning when the
target can be measured.
The zero shift function was used when
the R.V. is [], [((((] or [((((].
Shift the display when the
internal measurement
value (R.V.) is displayed
