OPERATIONS
UNIT SELECTION
1. The unit selection dip switches tell the microprocessor the correct water level difference for harvest
and the number of proximity switch circuits to monitor.
2. The unit selection dip switches are a series of 3 switches that can be placed in either the ON or OFF
position.
3. The following list shows the dip switch settings for each model:
NOTE: The unit selection switches are preset at the factory to the correct model. Use the chart
below if the control is replaced.
Model Switch 1 Switch 2 Switch 3 Proximity Switch Circuits
300 OFF OFF OFF 1
500 ON OFF OFF 1
600/800 OFF ON OFF 1
1000/1200 ON ON OFF 2
1400 OFF OFF ON 2
2400 ON OFF ON 4
