*2. Pr. 73 "0-5V/0-10V selection" changes the specifications of terminal "2".
POINT
•Bias setting for 0 to 5VDC (0 to 10VDC) input
•Gain setting for 0 to 5VDC (0 to 10VDC) input
•Bias setting for 4 to 20mADC input
•Gain setting for 4 to 20mADC input
For 4 to 20mADC input, set "4" in any of Pr. 60 to Pr. 63 (input terminal
function selection) and assign AU (current input selection) to any of terminals
RH, RM, RL and STR, and turn on the AU signal.
