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.

oPE30 Flow Meter Input Error
Cause Possible Solutions
Analog and pulse flow meters are programmed
simultaneously.
H6-01 is set to 5 and either H3-02, H3-06, or H3-10
is set to 22.
Reprogram H6-01, H3-02, H3-06, or H3-10.
Flow meter scaling is set to 0 and the flow meter
is being used as PID feedback.
P6-01 is set to 0.0, P1-02 is set to 25 and b5-01 is
set to a value higher than 0.
Reprogram P6-01, P1-02, or b5-01.

oPE31 Water Level/Suction Pressure/PI Aux
Cause Possible Solutions
One or both of the following conditions are
present:
• More than one of these parameters is set to a non-
zero 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.
