Multiplex Stabilization
Time
M-Stabilize Time
Sets the time used to stabilize the system when a pump is added
or shut down 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.
Function is active in contactor multiplex mode (P1-01 = 1).
Time pump protection and lead/lag control is suspended during
stabilization time.
Default: 2 s
Min.: 0
Max.: 3600

Pump 2 Frequency
Shutdown Level
P2 Shutdown Freq
Sets the level used for the multiplex pumping operation.
Parameter is active only when P3-02 is set to 0 or 2.
When P3-02 is set to 0 and a total of two pumps are running, the
last pump (Pump 2) that was brought online will be shut down
by opening the dedicated mult-function discrete output
(H2-0o = 80 to 84) when the output frequency falls below the
level set in this parameter for the time set in P3-09.
When P3-02 is set to 2 and a total of two pumps are running, the
last pump (Pump 2) 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 (setpoint minus
feedback) has exceeded the level programmed in this parameter
for the time set in P3-09.
Default: 40.0 Hz
Min.: 0.0
Max.: 400.0

Parameter is active only when P3-02 is set to 0 or 2.
Parameter function is similar to P3-50, except for Pump 3
instead of Pump 2.
