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

<1>

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
