Notice that the SETPT, ALARM, PID, and ODC function blocks in FCO101 all refer to AIN1 as the RG PTR
(range pointer) to determine the operating range of the function block. Be aware that making changes to a
configuration may require changing referenced RG PTRs. For example, in FCO105 (Ratio Set Control), the PID
controller output range is determined by the range of AIN2.
Try changing the default 0-100% range of analog input #1 (AIN1) to 100.0-500.0°F using the Configuration Road
