Online Tuning Parameter Setting Error
Parameters controlling online tuning are not set correctly.
Cause
Possible Solutions
One of the following errors occurred while online
tuning was enabled in OLV (A1-02 = 2):
• E2-02 was set below 30% of the original default
value
• E2-06 was set below 50% of the original default
value
• E2-03 = 0
Set E2-02, E2-03, and E2-06 to the correct values.

Flow Meter Input
Cause
Possible Solutions
Both analog and pulse input flow meters are
programmed at the same time.
Reprogram H6-01, H3-02, H3-06, or H3-10.
Flow meter scaling is set to zero and flow meter is
being used as PID feedback
Reprogram P6-01, P1-02, or b5-01

Water Level/Suction Pressure/PI Aux Cause
The input voltage offset adjustment has not been performed.
Cause
Possible Solutions
One or both of the following conditions are
present:
• More than one of these parameters is set to a
nonzero value: Q4-01, Q5-01, or Q6-01.
• Both Water Level/Suction Pressure (H3-
oo
=23) and PI Aux FB Level (H3-
oo
=27)
are programmed.
Confirm parameter settings of Q4-01, Q5-01, Q6-01, H3-02, H3-06 and H3-10.
