Symptom
Possible cause
Action
Incorrect vessel or PMD
dimensions
For volume application: Verify vessel dimensions.
See Vessel shape (2.7.2.) (Page 186).
For flow application: Verify PMD dimensions. See
PMD dimensions (2.13.5.) (Page 246).

Relay/pump configuration
errors - possible causes
include:
• A relay is assigned to
more than one function
(e.g. Relay 2 is as-
signed to both an ex-
ternal 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 Relay selector (2.8.1.1.) (Page 193)
and Other Control (2.10.) (Page 210).
• Verify that all 'ON' setpoints are greater
than their respective 'OFF' setpoints for
pump down applications (or vice versa for
pump up applications).
• Ensure range set in Level setpoint varia-
tion (2.8.2.6.2.) (Page 204) has not caused
'ON' or 'OFF' setpoints to overlap.
