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.
