Troubleshooting
Problem
Solution for Current
Output Models
Sensor has no
output.
Monitored load is not DC or is not on. Check that the moni-
tored load is DC and that it is actually on.
Polarity is not properly matched. Check and correct wiring
polarity.
Output signal is
too low.
The jumper may be set in a range that is too high for current
being monitored. Move jumper to the correct range.
Power supply is inadequate. Check power supply. Make sure
it is of sufficient voltage with all loads at maximum. The cur-
rent draw of EDC Series sensors is 2.0 VA.
Output load is too high. Check output load, being sure it is no
more than 500 ohms.
Output signal is
always at maxi-
mum.
The jumper may be set in a range that is too low for current
being sensed. Change the jumper position.
