Use this function when multiple pumps are to be controlled by rate of level change rather
than by setpoints.
The delay between pump starts is set by Delay Between Starts (2.8.2.8.1.) (Page 207).
This only applies to any relays set to pump control [RelayFunction (2.8.1.4.) (Page 195) =
Fixed Duty Assist, Fixed Duty Backup, Alternate Duty Assist, Alternate Duty Backup, Service
Ratio Duty Assist, Service Ratio Duty Backup, or First In First Out].
Note
•
All pump control relay ON and OFF setpoints must be the same value.

If the level is within 5% of Span (2.2.2.) (Page 169) of the OFF setpoint, the next pump is
not started.
