When the unit is operating in the Control Mode, the control algorithm determines the
output % required to correct for any difference between the process value and the
setpoint. The output calculation is affected by Tune Mode parameter adjustments. See
Figure 3-1 for proportional bandwidth effect on the output.
3.6 Current Proportioning Control
Current Proportioning control can be implemented on units provided with mADC current
output(s). Current Proportioning control provides a 4 to 20 mADC or 0-20 mADC output
in response to process value and setpoint. As with Time proportioning, the calculated
output % for Current proportioning is affected by the Tune Mode parameter
adjustments.
See Figure 3-1 for proportional bandwidth effect on the output.
