P3-02
0615H
Drive Multi/Maximum
Level
Max-Multi Level
Sets the maximum level used for multiplex pumping operation.
Parameter is active when P3-01 = 0 or P3-01 = 2 is selected.
P3-01=0:
When the output frequency rises above the level
programmed in P3-02 for a time specified in P3-04, the next available
pump will be added to the system by means of a multi-function digital
output closure (H2-XX = 40, 41).
P3-01=1:
Not Used.
P3-01=2:
When the output frequency rises above level programmed in
P3-02 and the delta feedback (setpoint minus feedback) has exceeded
the level programmed in P3-03 for a time specified in P3-04, the next
available pump will be added to the system by means of a multi-
function digital output closure (H2-XX = 40, 41).

Add Pump Delta Level
Add Pump D-Lvl
Sets the level used for multiplex pumping operation. The parameter is
active when P3-01 =1 or P3-01 = 2 is selected.
P3-01=0:
Not Used.
P3-01=1:
When the delta feedback (setpoint minus feedback) has
exceeded the level programmed in P3-03 for a time specified in P3-04,
the next available pump will be added to the system by means of a
multi-function digital output closure. (H2-XX = 40, 41).
P3-01=2:
When the output frequency rises above level programmed in
P3-02 and the delta feedback (Setpoint minus feedback) has exceeded
the level programmed in P3-03 for a time specified in P3-04, the next
available pump will be added to the system by means of a multi-
function digital output closure. (H2-XX = 40, 41).
Note:
Do not program this level too close to the system setpoint or
excessive cycling of the pump system may occur.

Shutdown Pump Delta
Level
Shdn Pump D-Lvl
Sets the level used for multiplex pumping operation. Parameter is
active when P3-01 = 1 or P3-01 = 2 is selected.
P3-01=0:
Not Used.
P3-01=1:
When the delta feedback (feedback minus setpoint) has
exceeded the level programmed in P3-05 for a time specified in P3-
06,the last pump that was brought online will be shutdown by means of
a multi-function digital output opening. (H2-XX = 40, 41).
P3-01=2:
When the output frequency drops below level programmed
in P3-09 or P3-10 (depends on last pump running) and the delta
feedback (feedback minus setpoint) has exceeded the level
programmed in P3-05 for a time specified in P3-06, the last pump that
was brought online will be shutdown by means of a multi-function
digital output opening. (H2-XX = 40, 41).
Note:
Do not program this level too close to the system setpoint or
excessive cycling of the pump system may occur.
