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-†† = 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-†† = 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-†† = 40, 41).

P3-01 = 2: When the output frequency rises above level programmed in
P3-02 and the delta feedback (Set-point 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-†† = 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-†† = 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-†† =
40, 41).

Note: Do not program this level too close to the system setpoint or
excessive cycling of the pump system may occur.
