Reset At the start of a reset event (a DIP switch change, sensitivity change, or
power cycle) the LED will turn off for 500 milliseconds, on for 500
milliseconds, off for 500 milliseconds, and then display its normal state.
High Speed Operation The LED is always on when the detector is in its high-speed mode of
operation.
Low Power Operation The LED will blink on once every 2 seconds when the detector is in its low
power mode of operation.
Detect 1 LED – The red Detect 1 LED is used to display the status of Channel 1. There are several different
statuses that can be displayed on this LED:
Off No vehicle present in the detection area and the loop is functioning
normally and there has not been a prior fault in the last week.
Reset in Fail-safe At the start of a reset event (a DIP switch change, sensitivity change, or
power cycle) the LED will turn off for 500 milliseconds, on for 500
milliseconds, off for 500 milliseconds, on for 500 milliseconds, and then
finally display its normal state.
Reset in Fail-secure At the start of a reset event (a DIP switch change, sensitivity change, or
power cycle) the LED will turn off for 500 milliseconds, on for 500
milliseconds, blink repeatedly with 50 milliseconds on followed by 50
milliseconds off for one second, and then display its normal state.
Detect The LED is on constantly when a vehicle is detected.
Open Loop When the detector senses that the loop is open, or the inductance is too
high, the LED will flash once every two seconds repeatedly, for the
duration of the fault. If the fault is corrected the LED will display the
appropriate Prior Fault indication.
Shorted Loop When the detector senses that a loop is shorted, or the inductance is too
low, the LED will flash twice every two seconds repeatedly, for the
duration of the fault. If the fault is corrected the LED will display the
appropriate Prior Fault indication.
Large Change Fault When the detector senses that a loop is experiencing a large inductance
change (greater than 25%), the LED will flash three times every two
seconds repeatedly, for the duration of the fault. If the fault is corrected
the LED will display the appropriate Prior Fault indication.
Prior Fault The detector is equipped with the ability to remember prior faults that
have occurred since the last power interruption or reset (changing a DIP
switch or the sensitivity). The detector will hold this status for one week
