MAXIMUM/PERCENT HIGH SUBMENU:
Specify in percent, the maximum value (99) for control output. If the output is analog proportional (Current or Voltage), then the maximum voltage or current, in percent, is specified. If the output is time proportional (Relay, SSR, or Pulse), then the maximum

The ON.OF control is a coarse way of controlling the process. The “Dead Band” improves the cycling associated with the ON.OF control. The PID control is best for processes where the set point is continuously changing and/or a tight control of the process variable is required. PID control requires tuning and adjustment of the “Proportional”, “Integral or Reset” and “Derivative or Rate” terms by a trial-
