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.
Figure 8-10. Batching 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 3.2.6
on page 33) to conÞgure digital input and output
functions.
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.
Figure 8-11. Batching Switch Wiring Diagram Example
To begin a batch process, turn the 3-way switch to
START
momentarily. If the STOP button is pushed
during the batch process, the process halts and the
button locks in the IN position.
The
START
switch is ignored while the STOP button is
locked in the IN position. The STOP button must be
turned counterclockwise to unlock it, then released
into the OUT position to enable the 3-way switch.
To restart an interrupted batch from the step where it
left off, do the following:
