22.04 ENABLE SPEED - The lag pump will only start if the start
value [SETPOINT-VALUE DECREASE] is met and the lead pump
has reached a pre-determined speed based upon the ENABLE
SPEED setting.
Normally the ENABLE SPEED should be set 98% of the
MAXIMUM SPEED [parameter 14.01].
Example- If MAXIMUM SPEED is set at 3550 RPM, then an
enable speed of 97% would enable the multi-pump
sequencing at speeds above 3443 RPM.

REMOVING (DE-STAGING) PUMPS
As the system demand decreases, the need for additional
pumps will also decrease. The SYNC parameters identify when
pumps are de-staged (shutdown) in normal multi-pump
control.
The primary consideration here is to ensure that when a lag
pump is shutdown, the remaining pumps are capable of
meeting the setpoint demand. The SYNC settings define how
much of a speed decrease will occur before one pump can be
de-staged. Goulds recommends the following for SYNC
settings:
