1–6 System Modes
The controller performs closed loop control in its normal control mode condition. The
controller will maintain its normal control mode when you are operating the user menu,
setup menu, or display mode, reloading default values, or applying event input signals.
Under certain conditions, the normal control mode will transfer to an exception mode.
The exception modes include: sleep mode, manual mode, failure mode, calibration
mode, and auto-tuning mode. All of these modes perform in an open loop control except
auto-tuning mode which performs ON-OFF plus PID closed loop control. The mode
transfer is governed by the priority conditions. A lower priority mode can not alter a higher
priority mode, as shown in figure 1.6.
