The outputs take on special meanings for this application.
OUT1 – This output automatically tracks the OVER range. When operating within the OVER range,
the output is in ACTIVE state. When operating outside of the OVER range, the output is in CUTOFF
state.
OUT2 – This output automatically tracks the UNDER range. When operating within the UNDER
range, the output is in ACTIVE state. When operating outside of the UNDER range, the output is in
CUTOFF state.
OUT3 – This output automatically tracks the ACCEPT range. When operating within the ACCEPT
range, the output is in ACTIVE state. When operating outside of the ACCEPT range, the output is in
CUTOFF state.
OUT4 – Remains permanently in CUTOFF state.
BATCHING APPLICATION (F30 = 7)
The batching application is designed for gain-in weight material batching. The TI-1680 will allow
batching of up to four materials using in-flight compensation or up to two material using fast/slow
valves. The TI-1680 does not have a provision for dumping the batch when complete, so this must
be done manually.
The outputs fire sequentially like this:
Weight
OUT 1
OUT 2
OUT 3
OUT 4
wt

SPT1
ON
OFF
OFF

SPT1 < wt

SPT2

SPT3

SPT3 < wt

SPT4

The outputs will not re-fire when the batch is dumped. For in-flight compensation, use the Cutoff
delay (B6)
The TI-1680 will automatically tare the scale upon batching start, but it will not auto tare between
each set point. Therefore, you must use total weights when programming set points.
There are three batching modes, which are selected thru the B3 setting:
MANUAL (B35 = 0) – The F1 key must be used to step the scale thru each set point.
AUTOMATIC (B35 = 1) – The F1 key must be pressed to start the batching process but once
started, the indicator runs thru each set point automatically. Once complete, the F1 key must be
pressed again to start the new batch.
FILLING (B35 = 2) – This mode is like automatic mode in that you press the F1 key once to start the
process. The difference lies in the output logic. The outputs will operate like the Standard Outputs.
However, the outputs will not re-fire when the filling operation is complete.
CONTINUOUS (B35 = 3) – This mode is like automatic mode in that you press the F1 key once to
start the process. The difference is that you need not press the F1 key to begin each batch.
