AUTO/MANUAL - The A/M key toggles the controller between automatic and manual control.

Press the “MANUAL”, key F1, or “AUTO”, key F2 to change state. Press “A/M” key again, or F4, to exit this mode.

TUNE - This key allows tuning of the controller. The first screen displays the controller action, DIRECT or REVERSE. The controller action may be viewed from the TUNE key, but it must be changed in the configuration mode. Press F4 to continue.

The Proportional Gain (PG), Time Integral (TI) and Time Derivative (TD) can be changed from this screen. Press F1, F2 or F3 to display the current value and edit the parameter. Press “CONT”, key F4 to continue.

The Derivative Gain (DG) and Manual Reset (MR) can be changed from this screen. Press F1 or F2 to display the current value and edit the parameter. Press F4 to go to the previous screen. Press the “TUNE” key again, or F3, to exit this mode.

ALPHANUMERIC Keys - Twelve white keys with alphanumeric characters and symbols are located toward the center of the keypad area. Pressing a 1-9, 0, -, or . key will display that character on the screen. These keys also have alphabetic characters and symbols that require the use of a SHIFT key. These numbers, letters and symbols are typically used in writing a range, damping value, tagname, message, or descriptor.

SHIFT Keys - Three shift keys are located below the alphanumeric keys. They are used to access a letter or symbol located in the upper left, center, or right portion of an alphanumeric key. To select an alphabetic character or upper symbol, press the proper SHIFT key (left, center, or right arrow) and then press the desired alphanumeric or symbol key.
