The Controller should need no adjustments other than the manual speed adjustment which varies the speed of the metering system motor.
Steps for a New or Replacement Unit
If replacing a defective unit, it is necessary to perform several adjustments. After the new controller has been installed follow these steps:
- Check the wiring using the Wiring Schematic ATV31/312 AS Auxiliary Unload for SQ and MEYER® ME-S Models 3724-00052 to be sure all wires are on the correct terminals. See Main Menu.
- Check for proper rotation of Unload System and reverse if necessary, by reversing only TWO motor lead wires at the AC motor wiring box.
