configured to operate the cylinders in series or parallel from one set of control signals, or
independently from two sets of control signals. See Double Mode (NH-EL 150-200 only) on
page 56 for more information.
Parallel or Series - One set of control signals (Double Mode = Series or Parallel) wire the
controls to terminal block A.
