Pre-Charge Lag Pump
Delay Time
PreChg Lag Delay

(0CF9) Pump 2 Frequency
Shutdown Level
P2 Shutdown Freq
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 mult-function discrete output
(H2-0o = 80 to 84) when the output frequency falls below the
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 mult-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.
Default: 40.0 Hz
Min.: 0.0
Max.: 400.0
P3-60
(11E5) Pump 3 Frequency
Shutdown Level
P3 Shutdown Freq

Parameter is active only when P3-02 is set to 0 or 2.
Parameter function is similar to P3-50, except for Pump 3
instead of Pump 2.
Default: 40.0 Hz
Min.: 0.0
Max.: 400.0
P3-70
(11EF) Pump 4 Frequency
Shutdown Level
P4 Shutdown Freq
Sets the level used for the multiplex pumping operation.
Parameter is active only when P3-02 is set to 0 or 2.
Parameter function is similar to P3-50, except for Pump 4
instead of Pump 2.
Default: 40.0 Hz
Min.: 0.0
Max.: 400.0

instead of Pump 2.
Default: 40.0 Hz
Min.: 0.0
Max.: 400.0

Parameter function is similar to P3-50, except for Pump 6
instead of Pump 2.
Default: 40.0 Hz
Min.: 0.0
Max.: 400.0

(0CFA) Pre-Charge Level
Pre-Charge Level
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
• The pre-charge time set in P4-03 expires
• The low water digital input is deactivated (#8F)
Default: 0.0 PSI
