5.4 Operator Programming Errors
Digital Operator Display
oPE18
Cause
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

oPE28
Cause
One of the following contradictory settings is true:
• S2-01 > S2-02
• S2-06 > S2-07
• S2-11 > S2-12
• S2-16 > S2-17
<1> Available in drive software versions PRG: 8551 and earlier.

oPE29
Cause
P1-01 parameter selection is not compatible with
Geothermal Mode (b1-01 = 5).
HOA Keypad Display
oPE30
Cause
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.
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.

oPE31
Cause
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.

oPE32
Cause
Low Water Level or Suction Pressure Turn-Off
Method (P9-51) is restricted to Water Level Source
of Analog Only (P9-50 = 0).

Online Tuning Parameter Setting Error
Parameters controlling online tuning are not set correctly.
Set E2-02, E2-03, and E2-06 to the correct values.
Sequence Timer Error
One or more of the sequence timers is not set in the correct order.
Correct the parameter settings.
Geothermal Set Error
Confirm b1-01 and P1-01 parameter settings.
Flow Meter Input Error
Reprogram H6-01, H3-02, H3-06, or H3-10.
Reprogram P6-01, P1-02, or b5-01.
Water Level/Suction Pressure/PI Aux
Confirm parameter settings of Q4-01, Q5-01, Q6-01, H3-02, H3-06 and H3-10.
Incompatible Network Water Level/Suction Pressure Mode
Confirm parameter settings for P9-50 and P9-51.
