Batching Switch Option Installation Instructions
PNs 19368, 19369
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 1. Batching Switch
The uncased switches (PN 19368) can be installed in
the front panel of an enclosure by drilling 7/8" holes
for the two switches. For models that have insufficient
room for switches on the enclosure, a special FRP
case is available for mounting the switch unit
remotely. The remote mounting kit includes case, 5
feet of 18 gauge cable, nylon ring, and cord grip for
sealing the cable connection to the indicator. Either
mounting method is waterproof and maintains a
NEMA 4X rating.
Both switches are wired into the indicator’s digital I/O
terminal strip as shown in Figure 2. 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 (Figure 3 on page
2), to configure digital input and output functions
using Bit 1 to set up BATSTRT and Bit 2 to set up
BATRUN.
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.

Figure 2. Batching Switch Wiring Diagram, 920i Example
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.
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:
1. Unlock STOP button (OUT position)
2. Turn 3-way switch to
START
To restart an interrupted batch from the first batch
step, do the following:
1. Turn 3-way switch to
ABORT
2. Unlock STOP button (OUT position)
3. Turn 3-way switch to
START
NOTE: Use this procedure (or the BATRESET serial
command) to initialize the new batch routine following any
changes to the setpoint configuration.
