Troubleshooting
Problem
Solution for Current
Output Models
Sensor has no output.
Power supply is not properly sized. Check power supply volt-
age and current rating.
Polarity is not properly matched. Check and correct wiring
polarity.
The core contact area may be dirty. Open the sensor and
clean the contact area.
Output signal is too
low.
The range may be too high for the current being monitored.
Select a difference EACF Series model with lower range.
The load current is not sinusoidal.
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
frequency.
The range may be too low for the current being monitored.
Select a different EACP Series sensor with a higher range.
Output signal is
always at minimum
frequency.
Monitored load is not AC or is not on. Check that the moni-
tored load is AC and that it is actually on.
