Selectable Pulse Time.
This feature sets the length of time that the pulse relay will be energised. 1 Second or
0.2 Second.
Indicators
Power Indicator.
This LED Indicator illuminates when power is present.
Detect Indicator.
This LED Indicator is illuminated when there is a vehicle over the loop or the loop is faulty. This
LED can also be used to determine the loop frequency. On reset, count the number of times the LED flashes.
Multiply this number by 10KHz.For example: if the LED flashes 6 times, then the loop frequency is between
60KHz and 70KHz.
Loop Fault Indicator.
This LED Indicator is illuminated when the loop is either open circuit or short circuit and is
used to give a visual indication of a faulty loop.
