INDICATORS

Green Power LED
Steady on when operating normally. See fault table for a flashing condition.

Fault	Display for Current Fault	Display for Prior Fault
Low Voltage	2 Hz with 50% duty cycle	NONE
Open Sensor	1 flash ON every 2 seconds	1 flash OFF every 2 seconds
Shorted Sensor	2 flashes ON every 2 seconds	2 flashes OFF every 2 seconds
Large Change	3 flashes ON every 2 seconds	3 flashes OFF every 2 seconds

Red Detect A LED
The LED will turn on when a vehicle is over the loop detection area. If delay is programmed, the LED will blink slowly during the delay interval. If extension is programmed, the LED will blink fast during the extension interval.

FAIL-SAFE or FAIL-SECURE

There are three jumpers internal to the detector that are used to select Fail- Safe or Fail-Secure modeof operation for the Relay A output. This setting determines what states the relay output should be in if a loop failure is detected. Fail-Safe operation has the relay activated. Fail-Secure has the relay deactivated. Most applications that are not high security will use the Fail-Safe mode of operation. The detector is shipped in the Fail-Safe mode from the factory.
