H3-08 Terminal A2 Signal Level

The H3-08 parameter (Terminal A2 Signal Level) allows the programmer to specify the signal that will be applied to the A2 analog input.
The A2 analog input can accept either a 0–10 Vdc or 4-20 mA signal as a reference. The iQpump drive also has a DIP switch (S1) on the
removable terminal board that must be set for the proper reference signal into the A2 analog input. The S1-2 dipswitch setting determines
the internal resistance of the A2 input while parameter H3-08 determines how the iQpump drive interprets the measured signal.
