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.

Add Pump Delay Time
Add Pump Dly Tm
Sets the delay time before a pump is added to the system. Works in
conjunction with parameters P3-02, P3-03, and P2-11 to P2-19.

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.
