The LCD contains nine regions that provide information on the PV, engineering units, mode of operation, output hold condition, fault indication, secondary variable, and soft key assignments. A view of the full LCD with smart key and mode text included is shown in Figure 4-1. The top set of icons indicates abnormal operating conditions such as the Hold, Fault, or Spike state. These icons only appear when the transmitter detects such a condition. They are active in all modes of operation. The mode of operation indicators, shown as right arrows grouped next to the mode text, indicate the current mode of operation. Only one indicator is lit at a time. The appropriate indicator appears when moving from one mode to the other. The mode of operation indicators are active in all modes of operation. OPERATING PROCEDURES OPERATOR INTERFACE CONTROLS 4 - 2 WTPEEUI520002A1 The PV appears in the three and one-half digit, seven-segment region. This display region is supported by the engineering unit region. These regions are normally active in all modes of operation; however, some programming states use these regions for data entry. The secondary variable is displayed in the six-character, 14-segment region. This display region displays secondary information and fault information in the measure mode and textual prompting in all other modes of operation. Due to the limited number of characters for this display region, much of the prompting takes the form of text abbreviations. Refer to Appendix C for programming text abbreviations. This region is active in all modes of operation. The smart key assignments are grouped into four sets of icons, each group directly positioned above one of the four smart keys. These icons are textual representations of the function for the associated smart key. Only one assignment will appear per smart key at any given time. Smart Keys A five-button, tactile keypad is located on the front panel. The four buttons below the display are embossed to easily show Figure 4-1.

A fifth hidden button, located at the center top of front panel, provides access to infrequently used functions. The four embossed keys are called smart keys since their functions are dependent on the mode and state of the instrument. Since these four keys do not have a preassigned function, icons appear over the key to indicate its function. If a smart key does not have an icon above it, this smart key does not have a function and initiates no action when pressed. Using this smart key method, a reduced number of keys can be used without complicating instrument functionality. Pressing the smart key initiates the displayed function of that smart key for each operating mode and state. For example, the NEXT function enables the cycling through of a series of programming states. The SELECT function enables entering into a given mode of operation or programming state. Using this method, the transmitter guides the user through
