P3-50: Pump 2 Frequency Shutdown Level
Sets the level at which the first lag pump (2nd pump in the system) will shut down or de-stage. This parameter is effective
when the P3-01 is set to 0 or 2 (pump staging is based on output frequency). When the output frequency falls below the P3-50
level for the time set in P3-09, the pump will be de-staged.

P4-01: Pre-Charge Level
Sets the level at which the drive will activate the pre-charge function. At start, if the PID is below the P4-01 setting, the drive
will run at the P4-02 frequency setting for the time set in P4-03. PID control is delayed until the pre-charge function stops.
The drive will exit the pre-charge function early if the feedback rises above the P4-01 setting or if a Low Water digital input
switch (H1-
oo
= 8F) deactivates. Pre-charge is useful to slowly fill or pressurize a system.
