Pump 2 Frequency

Shutdown Level

P2 Freq Shd Lvl

Sets the level used for multiplex pumping operation. Parameter is

active when P3-01 = 0 or P3-01 = 2 is selected.

P3-0 1= 0: When the output frequency falls below the level

programmed in P3-09 for a time specified in P3-06 and a total of 2

pumps are running, the last pump (Pump 2) that was brought online

will be shutdown by means of a multi-function digital output opening

(H2-XX = 40, 41).

P3-01 = 1: Not Used

P3-01 = 2: When the output frequency falls below the level

programmed in P3-09 and a total of 2 pumps are 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

(Pump 2) that was brought online will be shutdown by means of a

multi-function digital output opening (H2-XX = 40, 41).

Shutdown Level

P3 Freq Shd Lvl

Sets the 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 falls below the level

programmed in P3-10 for a time specified in P3-06 and a total of 3

pumps are running, the last pump (Pump 3) that was brought online

will be shutdown by means of a multi-function digital output opening

(H2-XX = 40, 41).

P3-01 = 1: Not Used

P3-01 = 2: When the output frequency falls below the level

programmed in P3-10 and a total of 3pumps are 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

(Pump 3) that was brought online will be shutdown by means of a

Multiplex Stabilization

Time

M-Stabilize Time

Sets the time used to stabilize system when a pump is added (brought

online) or shutdown during multiplex operation. When a pump is

added, the stabilize timer temporarily disables the lead / lag

functionality for the programmed time to prevent pump cycling.

Note: This function only active in the multiplex mode when P1-01 is

greater than 0.

During the stabilization time, the pump protection and lead-lag control

is suspended.

Delta Set-point Feedback

Acc / Dec Changeover

SP ACC/DEC Hyst.

Sets the level when the acceleration and deceleration times change over

to the values programmed in C1-05 and C1-06 respectively. This

function will activate when the difference between the delta setpoint

and feedback are within the level programmed in P3-12. This function

is used to improve the pump regulation.A value of 0 disables this

function.

Friction Compensation

start Frequency

Fric. Comp Lvl

Sets the level when the setpoint will be adjusted to compensate for the

friction losses. This function will activate when the output frequency

rises above the level programmed in P3-13. The maximum

compensation at maximum output frequency (E1-04) is specified by

maximum setpoint frequency (P2-10).

Note: This function is only active in simplex mode when P1-01 = 0.

Maximum Friction

Increase at Maximum

Frequency

Friction Inc

Sets the maximum setpoint friction compensation at maximum output

frequency (E1-04). This function is a linear calculation with P3-13 as

its starting frequency.

Example: P3-13 = 30.0 Hz, P3-14 = 10.0 psi, output frequency = 45.0

Hz and maximum frequency = 60.0 Hz

Set-point Increase = (45-30 Hz) x 10 psi / (60 Hz – 30 Hz)

≥ 5.0 psi

Note: This function is only active in simplex mode when P1-01 = 0.
