TROUBLESHOOTING
PROBLEM SOLUTION
Display shows
FULL
: Level of liquid is above the
FILL-H
setting: Check 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.
Display shows
EMPTY
: 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.
Display shows
WARMUP
: 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.
Display shows
LOST
: 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
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.
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 EchoPod
®
is current
limited to 22 mA. Anything above 23 mA indicates a short circuit.
No unit detected error 1 Both errors can occur when the Display is still plugged in when connecting
to WebCal. Remove the display from its plug and try again.
Data page read error 2
Data page read error X (X is
any number greater than 2)
Make sure display is removed. If issue persists, contact a Flowline
representative.
-1 No device is attached to
the USB Fob, or it is attached
incorrectly. Please correct
and try again. 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.
-2 Program to loader error
open wires Check the wires connected to the USB Fob as well as to the EchoPod
terminals.
