The early “E” boards have 8 dip switches. The latest “E”
boards have 10 dip switches.
NOTE:
1. TO IMPROVE BUILT-IN CLEANING Adjust switches 1&2 to
provide for longer flush and switches 5&6 to every cycle
pump-out 1/1. Do not adjust 1&2 on KM150/250 in high
ambient area.
2. DO NOT ADJUST 3, 4, 7, 8, 9 &10 from factory setting.
3. DO NOT MAKE CONNECTION to the red K-4 terminal
unless a special bin control / red connector is provided.
4. Dip-switches 9&10 are on improved “E” board only. If
original board has 8 dip-swithes, use default setting of
OFF/OFF for 9 & 10. If original board has 10 dip-switches,
match original “E” board settings.
