External EEPROM Error. The display will toggle between the two screens
shown with a 50% duty cycle. This is an indication that the data stored on
the external EEPROM memory module is corrupt. Press the
FUNC
pushbutton to copy the reference data stored on the internal EEPROM to
the external EEPROM memory module. If the error message does not
clear, the external EEPROM memory module is defective. Replace it with
a functional module and press the
FUNC
pushbutton to clear the error
message. If the error message still does not clear, return the detector to the
factory for servicing.
Warning: If the error message clears after pressing the FUNC
pushbutton, the user must confirm that the stored detector settings are
correct for the installation in question.
Internal EEPROM Error. The display will toggle between the two screens
shown with a 50% duty cycle. This is an indication that the data stored on
the internal EEPROM is corrupt. Press the
FUNC
pushbutton to copy the
reference data stored on the external EEPROM memory module to the
internal EEPROM. If the error message does not clear, the internal
EEPROM is defective. Return the detector to the factory for servicing.
Warning: If the error message clears after pressing the FUNC
pushbutton, the user must confirm that the stored detector settings are
correct for the installation in question.
Internal and External EEPROM Error. The display will toggle between
the two screens shown with a 50% duty cycle. This is an indication that
the data stored on the internal EEPROM and the external EEPROM
memory module is corrupt. Press the
FUNC
pushbutton to copy the
reference data stored on the microprocessor to the internal EEPROM and
the external EEPROM memory module. If the error message does not
clear, the internal EEPROM and the external EEPROM memory module
are defective. Return the detector to the factory for servicing. NOTE:
Clearing this error message will reset the detector to factory default
settings and will clear any previously mapped output(s).
Warning: If the error message clears after pressing the FUNC
pushbutton, the user must confirm that the stored detector settings are
correct for the installation in question.
Detection Reference Error. This is an indication that the internal EEPROM and the external
EEPROM memory module detection reference values do not match. Press the
FUNC
pushbutton to clear the error message.
Warning: If the error message clears after pressing the FUNC pushbutton, the user must
confirm that the stored detector settings are correct for the installation in question.
Warning: Clearing this error will reset all internal and external detection reference values.
If a vehicle (or vehicles) is (are) present over any or all loops at this time, the inductance
change caused by the vehicle(s) will be incorporated into the new baseline detection
reference and the vehicle(s) will no longer be detected.
