Max Setpoint 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 Setpoint (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.

Delay time before a Not Maintaining Setpoint or Loss of Prime Time
fault occurs. Pump protection criteria specified in P1-11 or P1-14 must
be met for the Drive to fault. The Drive will coast to a stop when a fault
occurs. A value of 0 disables both Loss of Prime and Not Maintaining
Setpoint faults.

Prime Loss Level
Used to detect loss of prime in the pump. If output current drops below

fmax, a “Loss Of Prime” fault occurs. The Drive will coast to a stop
when a 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.

Sleep Level
Sleep Level
Sleep activates when selected level (P2-01) reaches programmed sleep
level for time specified in P2-03. The level type is determined by P2-
01. A value of 0 disables this function. This function is only active
during running while operating in auto mode.
Display Units for Sleep Level P2-02 when P2-01 is programmed for
the following:
P2-01=0: >Display based on “Hz”
P2-01=1: >Display based on “A”
P2-01=2: >Display based on P1-02 Selection
Note: When P2-01 is set for a value of 2, display units will be
dependent on P1-02 setting.

Delta Sleep Feedback
Drop Level

When the Drive enters sleep mode, the software monitors the feedback
to detect a flow-no flow condition. If the PID Error (setpoint minus
feedback) exceeds the programmed level P2-04 within the
programmed time (P2-05) and the output frequency is greater than the
minimum frequency (P1-06), the sleep operation deactivates and the
Drive returns to normal operation. A value of 0 disables this function.
