(0CF9) 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
(H2-0
o
= 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
(H2-0
o
= 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
