Auxiliary Pump De-Staging (OFF)
The de-staging of the auxiliary pumps 2 and 3 will occur in the reverse order of the staging process described previously.
The de-staging of auxiliary pump 3 occurs when the output frequency falls below the Pump 3 Frequency Shutdown Level (P3-10) for the
time programmed in the Shutdown Pump Delay Time (P3-06).
The de-staging of pump 2 occurs when the auxiliary pump 3 is de-staged and the output frequency falls below the Pump 2 Frequency
Shutdown Level (P3-09) for the time programmed in the Shutdown Pump Delay Time (P3-06). Refer to Figure 115 for the de-staging of
the auxiliary pumps 2 and 3 using the “output frequency” control method.
