Setpoints 79
8.3 Batch Operations
Softkeys can be configured to allow operator control of
batch operations from the
720i front panel (see
Figure 8-9), Softkeys can be configured using
Revolution ® , serial commands, or the FEATURE menu
(see Section 3.2.3 on page 37).

Batch Start Starts batch process.
Batch Pause Pauses an active batch and turns off all
digital outputs except those associated
with concurrent and timer setpoints.
Processing is suspended until
Batch
Start is pressed again. Pressing Batch
S t a r t r e s u m e s t h e b a t c h a n d
re-energizes all digital outputs turned
off by the
Batch Pause.
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.
WARNING
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 indicator’s 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 3.2.5
on page 43) to configure digital input and output
functions.
Figure 8-10. Batching Switch
When configuration 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.
WARNING
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.
