High Feedback Level
High FB Level
The drive will display a “High Feedback Level (HFB)” alarm when the
feedback level rises above the programmed level. The alarm will turn
off when the feedback level falls below the programmed High
Feedback Level minus the Hysteresis Level (P1-13). This function is
active during running in the hand mode, auto mode, pre-charge and
thrust-bearing mode.
If P1-01 = 3, parameter P9-18 uses this value to calculate the quick de-
stage feedback level.

High Feedback Level
Fault Delay Time
Hgh Lvl Flt Time
The drive will initiate a “High Feedback Fault (HFB)” when the
feedback level rises above the programmed level for a time specified in
P1-10. The drive will coast to a stop when a fault occurs. This function
is active during running in all operation modes.
If P1-01 = 3, the function will stop all drives running on the network
when the system fault occurs.

Maximum SetPoint
Difference
Max Set-point Diff
When the drive is running and the difference between the setpoint and
the feedback exceeds the level in P1-11 for the time specified in P1-12,
the drive will trip on a “Not Maintaining Set-point (NMS)”. The drive
will coast to a stop when a fault occurs. A value of 0 disables this
function. This function is only active during running while operating in
auto mode.
If P1-01 = 3, the function is active on the lead drive, but will stop all
drives running on the network when the system fault occurs.

Prime Loss Level
Prime Loss Level
Used to detect loss of prime in the pump. If output current drops below
this level for the time specified in P1-12 and the output frequency is at
fmax, a “Loss Of Prime” fault occurs. The drive will coast to a stop
when a fault occurs.
If P1-01 = 3, the function is active on the lead drive, but will stop all
drives running on the network when the system fault occurs.

To use the low water function one of the digital inputs (H1-XX=85)
needs to be programmed. The low water input can be used for a low
water condition or in combination with the pre-charge function to
indicate the reservoir is filled. The low water input fault is only active
during running while operating in auto mode.
