P3-03
(0CCA)
Drive Multi/Maximum
Level
Max-Multi Level
Sets the maximum level used for the multiplex pumping
operation.
Parameter is active only when P3-01 is set to 0 or 2.
When P3-01 is set to 0, the next available pump will be added
to the system by a multi-function Discrete Output closure
(H2-0o = 80 to 84) when the output frequency rises above the
level set in this parameter for the time set in P3-05.
When P3-01 is set to 2, the next available pump will be added
to the system by a multi-function Discrete Output closure
(H2-0o = 80 to 84) when the output frequency rises above the
level set in this parameter and the delta feedback (setpoint minus
feedback) has exceeded the level programmed in P3-04 for the
time set in P3-05.
Default: 59.0 Hz
Min.: 0.0
Max.: 400.0

P3-04
(0CCB)
Add Pump Delta Level Add Pump D-Lvl
Sets the level used for the multiplex pumping operation.
Parameter is active only when P3-01 is set to 1 or 2.
When P3-01 is set to 1, the next available pump will be added
to the system by a multi-function Discrete Output closure
(H2-0o = 80 to 84) when the delta feedback (setpoint minus
feedback) has exceeded the level set in this parameter for the
time set in P3-05.
When P3-01 is set to 2, the next available pump will be added
to the system by a multi-function Discrete Output closure
(H2-0o = 80 to 84) when the output frequency rises above the
level set in P3-03 and the delta feedback (setpoint minus
feedback) has exceeded the level set in this parameter for the
time set in P3-05.
Note: Programming this parameter too close to the
system setpoint may cause the pump system to
cycle excessively.
Default: 0.0 PSI

Add Pump Delay Time Add Pump Dly Tm
Sets the delay time before a pump is added to the system.
Default: 2 s
Min.: 0
Max.: 3600

(0CCD)
Frequency Reduction
after Staging
FreqReduce@Stage
Sets the upper limit of the output frequency after a lag pump is
staged.
The upper limit of the output frequency is calculated by
subtracting the value of this parameter from parameter P3-03.
Output limit = P3-03 - P3-06
Default: 0.0 Hz
Min.: 0.0
Max.: 30.0

P3-07
(0CCE)
Frequency Reduction
after Staging Time
FreqReduce Time
Sets the amount of time that the output frequency will be limited
after lag pump is staged.
Default: 0.0 s
Min.: 0.0
Max.: 240.0

P3-08
(0CCF)
Shutdown Pump Delta
Level
Shdn Pump D-Lvl
Sets the level used for the multiplex pumping operation.
Parameter is active only when P3-02 is set to 1 or 2.
When P3-02 is set to 1, the last pump 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
(feedback minus setpoint) has exceeded the level programmed
in this parameter for the time set in P3-09.
When the P3-02 is set to 2, the last pump 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
drops below the level programmed in P3-50, P3-60, P3-70,
P3-80, or P3-90 and the delta feedback (feedback minus
setpoint) has exceeded the level set in this parameter for the time
set in P3-09.
Note: Programming this parameter too close to the
system setpoint may cause the pump system to
cycle excessively.
Default: 0.0 PSI

Min.: 0.0

Shutdown Pump Delay
Time
Shdn Pump Dly Tm
Sets the delay time before one of the additional line pumps is
shut down.
Default: 5 s
Min.: 0
Max.: 3600

Setpoint Boost
Maximum at De-Stage
MaxBoost@DeStage
Sets the maximum amount of boost that can be added to the
setpoint after a de-stage occurs.
Setting this parameter to 0.0 disables the function.
Default: 0.0 PSI
<1>
Min.: -20.0
Max.: 20.0
