Output (4-20 mA) Models
Solution for Voltage
Output (0-5/0-10V DC) Models
Sensor has no output
Power supply is not properly sized. Check power supply voltage and
current rating.
Monitored load is not AC or is not on. Check that the monitored load is
AC 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.
The load current is not sinusoidal
(EPRM Series only). Select
an EPRMR Series (True RMS)
sensor that works on distorted
waveforms.
Output load may be too low.
Check output load, making sure it
is at least 10 kilohm.
For loop-powered models, monitored current is below minimum
required. Loop the monitored wire several times through the aperture
until the “sensed” current rises above minimum. (‘Sensed Amps’ is
equal to ‘Actual Amps’ multiplied by the ‘Number of Loops.’)
Output signal is
always at maximum
The jumper may be set in a range that is too low for current being
sensed. Change the jumper position.
Output signal is
always at 4 mA
Monitored load is not AC or is not
on. Check that the monitored load
is AC and that it is actually on.
