TWO-LOOP RESTRICTIONS:

1.Time Duplex and Three Position Step Control are not available on Control Loop 2.

2.Position Proportional Control is not available on Two-Loop or Cascade Controllers.

3.If either Time Duplex or Three Position Step Control is selected as Control Loop 1 Output, then Time Simplex, Current/Time Duplex and Time/Current Duplex are not available for Control Loop 2 Output.

4.Current Duplex 50 % is not available on Model No. DC330E-EE-2XX.
