Sample Value Description
1
0.5 m** Sets the level at which pump 1 turns off. The first
cycle will use this setpoint. Subsequent cycles
rotate the setpoint among the pumps. For exam-
ple: In cycle 1, pump 1 turns off at 0.5 m. In the
next cycle, pump 2 will turn off at 0.5 m.
0.6 m** Sets the level at which pump 2 turns off.
Value
ADB
Sample Description
Value
1.3 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.
1.2 m* Sets the level at which pump 2 turns on.
Description
Sets the control algorithm used to trip the
pump relay to ALTERNATE DUTY BACKUP.
Only one pump can run at a time.
