Front Indicators
1. Green Led is ON - the detector is powered.
2. Red Led is ON - the detector detected a vehicle
3. Green Led is Blinking - the loop failed and is shorted or disconnected
4. Green Led is Blinking with two consecutive fast blinks - the loop failed in
the past and now is working correctly.
5. Red Led is Blinking at the start of a vehicle detection - the Filter function is
ON
6. Red Led is Blinking at the end of a vehicle detection - the Extend function
is ON
7. Red Led is Blinking during a vehicle detection - 4 minute limited presence
time has expired.
Front Controls
Reset This toggle switch when pushed momentarily down will reset the detector
Frequency Counter This toggle switch when pushed momentarily up will count the frequency on
the loop. This count is displayed by the Red Led blinks, each blink
represents frequency of 10K Hz. Count between 3 to 13 blinks confirms
that the loop detector is tuned to the loop.
Frequency This toggle switch controls the loop frequency. Set different frequencies
on adjacent loops. Verify frequencies with the frequency counter by
counting the Red LED blinks.
Back Controls
Sensitivity This rotary switch controls the detector sensitivity. During normal operation
the sensitivity level is set to 3 or 4.
