Display Shows E14:
Sensor is in a Fail-Safe state. The return sound pulses are not
reaching the transducer. First, cycle power off and on, waiting 5
seconds between the off and on states. If problem persists, check the
installation fitting against the Installation instructions in the manual.
Display is opposite of the
measured value:
Check the Display Value setting (2.1). Distance mode indicates the
distance from the liquid to the sensor. Height mode indicates the height
of liquid in the tank. Change the Display Value from Distance to Height
or vice versa to correct. This setting does not affect the 4-20mA output.
Transmitter indicates a
current of 0 mA:
Check the wiring for an open circuit. An open circuit is the most
common issue with a 0 mA signal.
Transmitter jumps to a
current reading between 19
and 20 mA:
Check the installation of the transmitter. Bad installation fittings will
cause false signals near the top of the tank, which typically translates to
a signal between 19 and 20 mA. Also look for interference just below
the transmitter. If the transmitter is installed in a metal fitting, switch to
a plastic fitting.
Transmitter indicates a
current over 23 mA:
Immediately check the wiring for a short circuit. The EchoPulse® is
current limited to 22 mA. Anything above 23 mA indicates a short
circuit.
