Symptom Cause Action
No response when
echo profile requested
via LUI (
3.2.1. Echo Pro-
file
)
Transducer is disabled. Set Transducer Enable (3.3.1.) on
page 205 to ENABLED, then
request an echo profile.
Configuration error 130
displayed Relay/pump configuration
errors - possible causes
include:
• A relay is assigned to more
than one function (e.g. relay 2
is assigned to both an
external totalizer and a
pump).
• Pump setpoints are out of
order.
• Wall Cling adjustment range
is too large.
• Verify that each relay is
assigned to one function only.
Review relay assignments
under Pump Control (page 151)
and Other Control functions
(page 175).
• Verify that all ’ON’ setpoints are
greater than their respective
’OFF’ setpoints for pump down
applications (or vica versa for
pump up applications).
• Ensure range set in Level
Setpoint Variation (2.7.2.1.2.) on
page 154 has not caused ’ON’ or
’OFF’ setpoints to overlap.
Echo profile request
results in an error icon
that displays for 5 sec-
onds before returning
to the echo profile
request menu. Another external communica-
tion is trying to access an echo
profile at the same time. Wait for several seconds and then
retry the echo profile request, or
disconnect / disable any external
communications that may be
requesting an echo profile.
Data log files are empty
or logging has stopped. • Data Logging is not enabled.
• USB extension cable has
been used (although may not
currently be connected).
• Verify that Data Logging is
enabled. See Data Logging
(2.10.) on page 173.
• If a USB extension cable has
been used (remove if currently
connected), a power reset of
the device is required to restart
Data Logging.
