H3-08 Drive Terminal A2 Signal Level
H3-08 is one of the special parameter settings required by the Bypass logic circuit. See Table 5.2.
The H3-08 parameter (Drive Terminal A2 Signal Level) allows the programmer to specify the signal that will be applied to the
A2 analog input (E7L Terminal TB3-3 or TB5-9). The A2 analog input can accept either a 0–10 Vdc or 4-20 mA signal as a
reference. The E7L also has a DIP switch (S1) on the PCB A2 that must be set for the proper reference signal into the A2
analog input. The S1-2 DIP switch setting determines the internal resistance of the Drive A2 input while parameter H3-08
determines how the Drive interprets the measured signal.
