Vehicle Detector LED
There are two small LEDs on the vehicle detector that can be in one of three
states when powered and operating:
• Steady green—indicates that power is applied and no vehicle is
currently detected.
• Flashing green, single flash every 1.5 seconds—indicates an open loop
fault (a wire is disconnected or severed).
• Flashing green, double flash every 1.5 seconds—indicates a shorted
loop fault (the loop wires are making unwanted contact at some point
before they reach the loop detector).
• Steady red—indicates that power is applied and a vehicle is currently
detected.
Note:
The vehicle detector fails closed; therefore if there is a fault, the system
assumes that there is a vehicle present.
