Error Messages and Countermeasures

This section outlines the error messages displayed on the main display and the
countermeasures for those messages.
Display
E-CHL There are two Sensors but only one
Amplifier Unit connected
E-BRT The received light intensity is
(flashing) saturated or a distance measurement
(*1) error has occurred.
E-DAT Two-sensor operation
communications data error
E-DRK The received light intensity is
(flashing) insufficient or a distance
(*1) measurement error has occurred.
E-EEP EEPROM data error
E-HED The Sensor Head is disconnected.
E-LUL A distance error has occurred.
(flashing)
(*1)
E-SHT One or all of the judgement outputs
are short-circuited.
E-THK The thickness T is not set for thickness
operation.
Error
• If two Amplifier Units have been connected, turn
OFF the power supply and check that the Amplifier
and Calculating Units are connected correctly.
• If only one Amplifier Unit is being used, connect
another Amplifier Unit temporarily and turn OFF the
two-sensor operation, or initialize the settings data.
• If the gain setting has been changed, either set the
optimum gain or set the gain to auto mode.
• If this does not solve the problem, use a suitable
workpiece.
Operation will recover automatically when the error is
solved.
• Change the mode for the CH1 Amplifier Unit to RUN.
• Turn OFF the power supply and check that the
Amplifier and Calculating Units are connected
correctly.
Replace the Amplifier Unit or the Calculating Unit if
the above countermeasures do not solve the
problem.
• If Smart Monitor is used, this error may occur
depending on the communications conditions.
• If the gain setting has been changed, either set the
optimum gain or set the gain to auto mode.
• If this does not solve the problem, use a suitable
workpiece.
Operation will recover automatically when the error is
solved.
Hold down the ENT Key for three seconds or longer.
Once the data has been cleared, cycle the power
supply.Replace the Amplifier Unit if the above
countermeasure does not solve the problem.
Turn OFF the power supply, check the connection for
the Sensor Head, and then turn ON the power supply
again.
If this does not solve the problem, the Sensor Head is
defective. Replace the Sensor Head.
Place a workpiece in the measurement area.
Operation will recover automatically when the error is
solved.
Turn OFF the power supply, check that the HIGH,
PASS, and LOW output lines are not short-circuited,
then turn ON the power supply again.
Set an appropriate thickness T.
