A5E33329501 SITRANS LUT400 (HART) – OPERATING INSTRUCTIONS
Cause
Transducer is disabled.
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.
Another external communica-
tion is trying to access an echo
profile at the same time.
• Data Logging is not enabled.
• USB extension cable has
been used (although may not
currently be connected).
Action
Set Transducer Enable (3.3.1.) on
page 205 to ENABLED, then
request an echo profile.
• 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.
Wait for several seconds and then
retry the echo profile request, or
disconnect / disable any external
communications that may be
requesting an echo profile.
• 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.
