Precharge LagSel Selects which of the lag pumps can come on during a pre-charge.
0: Disabled 0: Disabled
2: Pump2 (H2-0X=80) 2: Pump 2 (H2-0o = 80)
3: Pump3 (H2-0X=81) 3: Pump 3 (H2-0o = 81)

Sets the length of time that the lag pump specified in P3-40 is
Precharge Lag Tm energized.
Determines whether the lag pump set in pre-charge (P3-40)
Post PreChg Lag
turns off or maintains its state when pre-charge is completed.
0: Turn Off
0: Turn off
1: Continue
1: Continue
Sets the length of time that the drive is in the pre-charge mode
PreChg Lag Delay before the lag pump set in P3-40 is energized.
Sets the level used for the multiplex pumping operation.
Parameter is active only when P3-02 is set to 0 or 2.
When P3-02 is set to 0 and a total of two pumps are running, the
last pump (Pump 2) that was brought online will be shut down
by opening the dedicated multi-function discrete output
(H2-0o = 80 to 84) when the output frequency falls below the
P2 Shutdown Freq level set in this parameter for the time set in P3-09.
When P3-02 is set to 2 and a total of two pumps are running, the
last pump (Pump 2) that was brought online will be shut down
by opening the dedicated multi-function discrete output
(H2-0o = 80 to 84) when the delta feedback (setpoint minus
feedback) has exceeded the level programmed in this parameter
for the time set in P3-09.
Sets the level used for the multiplex pumping operation.
Parameter is active only when P3-02 is set to 0 or 2.
P3 Shutdown Freq
Parameter function is similar to P3-50, except for Pump 3
instead of Pump 2.
Sets the level used for the multiplex pumping operation.
Parameter is active only when P3-02 is set to 0 or 2.
P4 Shutdown Freq
Parameter function is similar to P3-50, except for Pump 4
instead of Pump 2.
Sets the level used for the multiplex pumping operation.
Parameter is active only when P3-02 is set to 0 or 2.
P5 Shutdown Freq
Parameter function is similar to P3-50, except for Pump 5
instead of Pump 2.
Sets the level used for the multiplex pumping operation.
Parameter is active only when P3-02 is set to 0 or 2.
P6 Shutdown Freq
Parameter function is similar to P3-50, except for Pump 6
instead of Pump 2.
LCD Display
Runs the drive at the frequency set in P4-02.
The drive will stop when one of the following conditions occurs:
• The feedback level rises above the level set in P4-01
Pre-Charge Level
• The pre-charge time set in P4-03 expires
• The low water digital input is deactivated (#8F)
Sets the frequency reference used when the Pre-Charge function
is active.
