The Options module DIP switches control what type of input is used. To use a 2-10 VDC signal
switch 2-1 should be in the off position. To use a 4-20 mA signal, switch 2-1 should be in the on
position.
The user must also specify the type of External Setpoint Input (4-20 mA or 2-10 VDC) in the
machine configuration menu.
