Motherboard Mounted 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 motherboard mounted EEPROM is corrupt. Press
the
FUNC
pushbutton to copy the reference data stored on the internal
EEPROM to the motherboard mounted EEPROM. If the error message
does not clear, the motherboard mounted 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 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 motherboard mounted EEPROM 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 motherboard mounted
EEPROM is corrupt. Press the
FUNC
pushbutton to copy the reference
data stored on the microprocessor to the internal EEPROM and the
motherboard mounted EEPROM. If the error message does not clear, the
internal EEPROM and the motherboard mounted EEPROM 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
motherboard mounted EEPROM 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.

LOOP CHECK PASS / FAIL INDICATIONS
The Loop Check feature is enabled whenever the Loop Check Timer for a specific loop input
is set to a value between 1 and 255 minutes. When the Loop Check Timer has timed out, the
detector will automatically short the check loop to simulate vehicle detection. If the
percentage of inductance change is greater than or equal to -0.04%
∆
L/L, and the channel on
which the current loop check test is selected and being viewed on the LCD, the display will
show
PAS
