TROUBLESHOOTING
Check loop resistance on the
appropriate loop pins on the
control board connector, between
0.5 ohms and 5 ohms.
Green LED flashes
Loop wire shorted or open
Check loop resistance on the
appropriate loop pins on the
control board connector.
Green LED flashes, 2 fast
Loop was previously shorted
or open
1. Perform megger test from loop
lead to ground, should be >100
megohms
2. Check loop connections to
terminals
3. Check splices are properly
soldered and sealed against
moisture
4. Observe display, level indicated
on display indicates residual
frequency shift from vacant loop to
vehicle presence, press
Frequency Count switch to
reinitialize the detector
Detector remains in detect
after vehicle has left loop 1. Faulty loop
2. Poorly crimped terminals
3. Loose connections
1. Perform megger test from loop
lead to ground, should be >100
megohms
2. Check loop connections to
terminals
3. Check splices are properly
soldered and sealed against
moisture
4. Set adjacent loops to different
frequencies (see Frequency Setting)
Intermittent detection
1. Faulty loop
2. Poorly crimped terminals
3. Loose connections
4. Cross-talk between
adjacent loops
1. Check loop resistance on the
appropriate loop pins on the
control board connector, between .
5 ohms and 5 ohms.
2. With vehicle on loop, observe
display, set sensitivity to the
level indicated on the display
No detection
1. Loop wire shorted or open
2. Loop sensitivity set too
low
