Terminal A2 Signal
Level Selection
0: 0 to 10 V
1: -10 to 10 V
2: 4 to 20 mA
3: 0 to 20 mA
Default: 2

4. Verify the proper Terminal A2 Function Selection (H3-10), typically ‘B’ for PID Feedback.
If terminal A2 is not chosen as the primary transducer feedback input,
H3-10 Terminal A2
Function Selection
must be disabled and terminal A1 or A3 must be configured for the
appropriate settings following steps 1-4.
