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).
Symptom cause Action
Relay not activating Relay not programmed Program relay.
Incorrect relay setpoints Verify setpoints.
Relay not activating

Incorrect relay setpoints Verify setpoints.
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 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.
