(Page 185) or Pump Control Mode
(2.7.1.5.) (Page 185)
ADA Sets the control algorithm used to trip the pump
relay to ALTERNATE DUTY ASSIST. Multiple
pumps can run simultaneously.
7.7.2.3 Set the ON Setpoints
Parameter
Sample Value
1
Description
ON Setpoint Pump 1
(2.7.1.6.) (Page 186)
1.0 m* Sets the level at which pump 1 turns on. The first
cycle will use this setpoint. Subsequent cycles
rotate the setpoint among the pumps. For exam-
ple: In cycle 1, pump 1 turns on at 1 m. In the
next cycle, pump 2 will turn on at 1 m.
ON Setpoint Pump 2
(2.7.1.8.) (Page 186)
1.1 m* Sets the level at which pump 2 turns on.
