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
Max-Multi Level 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.
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:
Sets the delay time before a pump is added to the system.
Sets the upper limit of the output frequency after a lag pump is
staged.
FreqReduce@Stage 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
Sets the amount of time that the output frequency will be limited
after lag pump is staged.
FreqReduce Time
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
Shdn Pump D-Lvl
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:
Sets the delay time before one of the additional line pumps is
shut down.
Shdn Pump Dly Tm
Sets the maximum amount of boost that can be added to the
setpoint after a de-stage occurs.
MaxBoost@DeStage
Setting this parameter to 0.0 disables the function.
Description
Programming this parameter too close to the
system setpoint may cause the pump system to
cycle excessively.
Programming this parameter too close to the
system setpoint may cause the pump system to
cycle excessively.
