Troubleshooting
PROBLEM SOLUTION
Transmitter indicates a
current of 0 mA Check the EchoSonic® II 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 EchoSonic® II installation. 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 Check the wiring for a short circuit. The EchoSonic® II is current limited
to 22 mA. Anything above 22 mA indicates a short circuit..
Transmitter always jumps
to LOST condition Check the dimensional configuration ( Sensor Height and Fill‐Height ) of
the EchoSonic® II. Make sure that the Fill‐H setting corresponds to the
full level of liquid (from the bottom up) and not the distance from the
transmitter to the liquid (top down).
Output of transmitter is
opposite of the level of
liquid Check the Output at Empty Setting.
