Basic Functionality This section provides information about the IND780’s basic functionality. Configuration of these areas of functionality can be accessed through the different areas of the setup menu tree – an example view is shown in Figure 2-10. H Additional areas of functionality specific to application software available for the IND780 are addressed in the specific application manuals. Basic functions addressed in this section include: • Select scale • MinWeigh • Over/Under Mode • Zero • Target Comparison • Time and Date • Tare • SmartTrac • Reports • Unit Switching • Display Sizes • Calibration Test • Expand By 10 • Display Colors • Display Contrast • Print • Bar Graph Mode • Information Recall Select Scale The Select Scale function button is used to switch between scale bases when multiple platforms are connected to the IND780. Zero The Zero function is used to set or reset the initial zero reference point of the IND780. There are three types of zero setting modes: • Automatic Zero Maintenance (AZM) • Power-Up • Pushbutton
Automatic Zero Maintenance (AZM) enables the IND780 to compensate for the buildup of small amounts of weight and track itself back to the center of zero. Within the AZM operating range (programmable from 0.0 to 9.9 divisions), when the terminal is in a no motion condition it makes small adjustments to the current zero reading to drive the weight reading toward the true center-of-zero. When the weight is outside of the programmed AZM range, this feature is not functional. Power-Up Zero Power-Up Zero enables the IND780 terminal to capture a new zero reference point after power is applied. If there is motion during a power-up zero capture function, the terminal will continue to check for a no-motion condition until zero is captured. Power-up zero can be disabled (RESTART on power up) or enabled (Reset on power up), and a range above and below calibrated zero can be configured. The range is programmable from 0% to 100% of capacity and can include a positive range and also a range below calibrated zero. Pushbutton Zero The pushbutton (semi-automatic) zero function can be accomplished by pressing the ZERO scale function key, by programming a discrete input, by a PLC or serial command, or by an application. The range for all types of semi-automatic zero is selectable (0% to 100%) plus or minus from either the calibrated zero point (if power-up zero is disabled) or from the initial zero setting point (if power-up zero is enabled). Remote initiation of the semi-automatic Zero command is possible via a discrete input, an ASCII ‘Z’ command sent serially (CPTZ and SICS), a command initiated by the PLC interface, or from an application.
