8.3 Batch Operations
Softkeys can be conÞgured to allow operator control
of batch operations from the
920i front panel (see
Figure 8-9), Softkeys can be conÞgured using iRev ,
serial commands, or the FEATURE menu (see
Section 3.2.3 on page 34).

Batch Start Starts batch process.
Batch Pause Pauses an active batch. Processing is
suspended until
B a t c h S t a r t is
pressed again.
Batch Reset Stops and resets an active batch to the
beginning of the process.
Batch Stop Stops an active batch and turns off all
associated digital outputs.
To prevent personal injury and equipment
damage, software-based interrupts must
always be supplemented by emergency
stop switches and other safety devices
necessary for the application.
Batching Switch
The batching switch option, PN 19369, comes as a
complete unit in an FRP enclosure, with legend plate,
locking stop switch (mushroom button), and a
run/start/abort 3-way switch.
Both switches are wired into the indicatorÕs digital I/O
terminal strip as shown in Figure 8-11. Each switch
uses a separate digital input.
Once cables and switches have been connected to the
indicator, use the setup switch to place the indicator in
setup mode. Use the DIG I/O menu (see Section 3.2.6
on page 42) to conÞgure digital input and output
functions.
Figure 8-10. Batching Switch
When conÞguration is complete, exit setup mode.
Initialize the batch by turning the 3-way switch to
ABORT , then unlock the STOP button (the STOP
button must be in the OUT position to allow the batch
process to run). The batching switch is now ready to
use.
If no digital input is assigned to
BATRUN, batching proceeds as if
BATRUN were always on: the batch
will start when the 3-way switch is turned to RUN, but the
STOP mushroom button will not function.
