TM 5-3895-374-24-2 955-257 SECTION 2-FUNCTIONS 2.1 MODES OF OPERATION The controller can operate in one of two MODES i.e. the OPERATOR mode or the TUNE mode. This distinction is made because different displays appear on the front of the controller for each mode and you can perform different functions in each mode. The OPERATOR mode is the normal mode of operation. It is explained in detail in Section 3. The TUNE mode is used for tuning and programming the controller prior to going on-line or during operation. Tuning is explained in detail in Section 4. A third mode is used for calibration of the controller. This CAL mode is explained in detail in Section 6. The controller cannot operate while in the CAL mode. Before putting the controller into operation please read the rest of this section, which explains the display and keypad functions. 2.2 DISPLAY The front panel multicolor alphanumeric, vacuum fluorescent display provides all controller communications with the operator.
