920i Installation Manual V4.01 - Rice Lake Weighing Systems

3.1.2 Serial Command ConfigurationThe serial command set can be used to configure the920i indicator using either a personal computer,terminal, or remote keyboard. Like iRev 4, serialcommand configuration sends commands to theindicator serial port; unlike iRev 4, serial commandscan be sent using any external device capable ofsending ASCII characters over a serial connection.Serial commands duplicate the functions availableusing the indicator front panel and provide somefunctions not otherwise available. Serial commandscan be used to simulate pressing front panel keys, toconfigure the indicator, or to dump lists of parametersettings. See Section 9.0 on page 89 for moreinformation about using the serial command set.3.1.3 Front Panel ConfigurationUse the CONFIG submenu under the SCALES menuto configure A/D scales. For example, in an indicatorwith a single-channel A/D card installed in Slot 1, theScale Configuration display will show the A/D listed(Slot 1 Channel 1) under the AVAILABLE A/D’s column.Use the left navigation key to select the A/D, thenpress the center softkey, Add. The A/D is then movedto the Associated A/D’s column. If no other A/D’s arelisted in the AVAILABLE A/D’s column, the centersoftkey changes to Done, as shown in Figure 3-2.Press Done to exit the Scale Configuration display.See Section 10.4 on page 111 for information aboutconfiguring serial scales.Figure 3-2. Scale Configuration Display3.1.4 Multi-Range and Multi-Interval ScalesThe 920i supports multi-range and multi-intervalscales of either two or three ranges or intervals.Multi-range scales provide two or three ranges, eachextending from zero to the maximum capacityspecified for the range, that can specify different scaleintervals (graduations). The scale interval changes asthe applied weight increases but does not reset tolower range intervals until the scale returns to zero.Multi-interval scales divide the scale into two or threepartial weighing ranges, each with different scaleintervals. The scale interval changes with bothincreasing and decreasing loads applied.To configure a multi-range or multi-interval scale, usethe SPLIT parameter to select 2RNG or 3RNG (formulti-range scales), or 2INTVL or 3INTVL (formulti-interval scales). Selecting a SPLIT value otherthan OFF allows specification of decimal point,display divisions, and maximum capacity for eachrange or interval.The SPLIT parameter is used to enable multi-range ormulti-interval. The SPLIT parameter is in theSCALES menu, see Figure 3-4, and Table 3-2. Aftersetting the SPLIT parameter, the Format menuselection will change as shown in Figure 3-6, andTable 3-4.If using streaming with multi-range or multi-interval,the stream must be set to Custom in iRev 4. TheTokens for Secondary and Tertiary Units must be setto L or K to match the Primary, refer to the SerialMenu, Tokens Parameter, in Section 3.2.2 on page 37.They can be set using iRev 4 or through the frontpanel.In multi-range, each range has its own capacity anddisplay division, extending from zero. The scaledisplay division will increase at the entered rangecapacities, either two or three ranges. Once the rangehas increased to the next level, the display divisionwill remain in new range until the scale returns tozero. The tare value can be taken in any range.For example,Range 1 is 0 - 3000 x 1 lb.Range 2 is 0 - 10,000 x 5 lb.In multi-interval, the scale has one capacity, which issegmented into weighing intervals, either two or threeintervals, each with different display division sizes.As the weight value exceeds an interval or set interval,the display division will increase, as the weight fallsbelow an interval or set interval, the display divisionwill decrease. The tare can only be taken in the firstinterval.For example,Range 1 is 0-30 x 0.01 lb.Range 2 is 30 - 60 x 0.02 lbs.Configuration 23
