IQ plus 800/810 Installation Manual
NORMAL, except that an automatic print command occurs after the
scale achieves standstill, and when the scale load is reduced to 0 ±10
display divisions. Following the print command, the peak value is
cleared and reset automatically. As in the above two modes, the peak
hold value can also be cleared by the CLEAR key, or by a manual press
of the PRINT key.
The peak hold function will only track the primary analog input of the
indicator. The digital display can be set to display other analog inputs or
gross weight information data using the N/G mode key during peak hold
function cycles.
BAR GRAPH (OPTIONAL)
The Bar Graph feature (represented by the BAR GRF menu) has 48 LED
segments that can be scaled to represent weight, speed, or batch step
progress. It can be used to monitor the progress of batch steps in a batching
sequence, with assigned segments lighting when a particular batch step is
active. The bar graph can also be used as a visual graph to monitor indi-
vidual setpoint operations like a filling operation, with segments progres-
sively lighting as the fill weight increases until all 48 are lit when the
setpoint weight is achieved.
The bar graph can also be set up around a band, rather than a single setpoint
value. In this case, the segments begin to light at the bottom of the band
value and are entirely lit at the middle of the band. Then they progressively
extinguish until all are off at the top end of the band.
The bar graph function is enabled in the Setup Mode. Parameter settings are
found under the first level BAR GRF menu. See Figure 8-3 for layout.
During a batching operation where the setpoints are configured as steps in a
batching sequence, the bar graph can be programmed to illuminate the
appropriate three segments in the sequence while a particular setpoint (batch
step) is active. This is the "TWNKL" selection mode shown in Figure 8-3.
TWNKL provides a visual indication of which setpoint (of setpoints 1 —
16) is "hot" during a batch process. Continuous setpoints that are not part of
the batch process are shown as continuously on by the bar graph.
Another use of the bar graph is to monitor the active weight value of a
setpoint during a filling operation. This gives the operator a visual indication
of the level of completion of a particular setpoint. This is the "GRAPH"
selection mode. If the band width ("BAND") is set to equal the setpoint
value, each of the 48 segments is equal to approximately 2 percent of the
total set point value. When the ingredient begins to fill, all of the bar graph
segments will be OFF. The segments will begin to light from left to right as
the weight value increases to meet the setpoint value.
