Level of liquid is above the FILL-H setting:
making sure the FILL-H setting is high enough so the level of liquid is below
the FILL-H setting. The Fill-H setting is the distance from the bottom of the
tank to the Full level of liquid.
Level of liquid is beyond the HEIGHT setting: Check the HEIGHT setting,
making sure the HEIGHT setting is low enough so the level of liquid is
above the HEIGHT setting.
Typically occurs when power is being applied to transmitter. Indicates a
weak power supply, bad wire connections or the sensor is out of the
operational range.
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.
Check the DISPLAY setting. AIR mode indicates the distance from the
liquid to the sensor. LIQUID mode indicates the height of liquid in the tank.
Change the DISPLAY mode from AIR to LIQUID or vice versa to correct.
Check the wiring for an open circuit. An open circuit is the most common
issue with a 0 mA signal.
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.
Immediately check the wiring for a short circuit. The EchoPod
limited to 22 mA. Anything above 23 mA indicates a short circuit.
Both errors can occur when the Display is still plugged in when connecting
to WebCal. Remove the display from its plug and try again.
Make sure display is removed.
representative.
1. Check the wires connected to the USB Fob as well as to the EchoPod
terminals.
2. Make sure the cable length between the sensor and the computer is less
than 15' of total cable.
3. Make sure the display was removed from its plug.
4. If this persists, reboot computer in SAFE mode and re-install the
®
WebCal installer program.
Check the wires connected to the USB Fob as well as to the EchoPod
terminals.
