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.
Note:
Functions on pins 6 and 10 are reversed if DIP 4 is set to OFF
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.
