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
(H2-0
o
= 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
(H2-0
o
= 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
(H2-0
o
= 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
(H2-0
o
= 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.
Min.: 0.0
Max.: 6000.0

P3-05
(0CCC) 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
–
P3-06
(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
