7.7.4.1 Set the common parameters
Prerequisite: Substitute the details of your application in place of the sample values
provided. If you are bench testing the device, set your test values to be the same as the
sample values.
Sensor Mode (2.1.2.) (Page 168) or Sensor Mode (2.1.3.)
Level
Response rate in Quick Start (Page 59) Medium
Transducer (2.1.6.) (Page 170)
Units (2.1.1.) (Page 168)
Low Calibration Point (2.2.1.) (Page 171)
High Calibration Point (2.2.2.) (Page 172)
7.7.4.2 Set Relays to ALTERNATE DUTY ASSIST (ADA)
Pump Control Mode (2.7.1.4.)

Mode (2.7.1.5.) (Page 185)
ADA Sets the control algorithm used to trip the pump relay
to

7.7.4.3 Set the ON Setpoints
ON Setpoint Pump
1 (2.7.1.6.)
(Page 186)
0.4 m* Sets the level at which pump 1 turns on. The first cycle
will use this setpoint. Subsequent cycles rotate the set-
point among the pumps. For example: In cycle 1, pump 1
turns on at 0.4 m. In the next cycle, pump 2 will turn on at
ON Setpoint Pump
2 (2.7.1.8.)
0.3 m* Sets the level at which pump 2 turns on.

7.7.4.4 Set the OFF Setpoints
OFF Setpoint Pump 1
(2.7.1.7.) (Page 186)
1.3 m** Sets the level at which pump 1 turns off. The first cycle
will use this setpoint. Subsequent cycles rotate the set-
point among the pumps. For example: In cycle 1, pump 1
turns off at 1.3 m. In the next cycle, pump 2 will turn off at
OFF Setpoint Pump 2
(2.7.1.9.) (Page 186)
1.2 m** Sets the level at which pump 2 turns off.
