START/STOP/RUN BATCHING SWITCH (OPTIONAL)
The Batching Switch option comes as a complete unit with legend plate,
locking stop button, and run/start/abort 3-way switch (Figure 8-26). With the
SS and HE models, the unit can be mounted directly on the face of the case
by drilling 7/8-inch holes for the two switches. The 810 DT and 800 models
have insufficient room for switches on the case, and a special FRP case is
available for mounting the switch unit remotely. The remote mounting kit
includes case, 5 feet of cable, and O-ring and cord grip for sealing. Either
mounting method is waterproof, and maintains a NEMA 4X rating.

1. The red STOP button must be in the OUT position to allow the batch
process to run. This enables BATRUN with a TTL-low (ON) condition.
To begin a batch process, the 3-way switch must momentarily be turned
to START. If the STOP button is pushed during the batch process, the
process halts and the button locks in the IN position. Turning the 3-way
switch to START while the STOP button is locked IN will not resume
the batch process. The STOP button must be turned counterclockwise to
unlock it, and release it into the OUT position.
2. When the STOP button is used to halt a batching operation, the operation
will continue where it left off by following these steps:
a. Unlock the STOP button to OUT.
b. Turn the 3-way switch to START.
3. When the STOP button is used to halt a batching operation, the operation
will abort and return to the beginning step by following these steps:
a. Before unlocking the STOP button, turn the 3-way switch to ABORT.
b. Unlock the STOP button to OUT.
c. Turn the 3-way switch to START.
Both switches are wired into the indicator's
digital input connection terminal according
to the wiring in Figure 8-27 on the following
page. Each switch requires a separate digital
input, leaving one of the IQ plus 800/810's
original three digital inputs available for
other use. The 5-VDC digital ground
required to operate the switches is available
on the indicator's digital input terminal at J4-
8 or J4-9.
After the switches are mounted and wired,
the IQ plus 800/810's software must be
configured for the correct digital input
functions. (Detailed configuration instruc-
tions are found on the following page.)
The batching switch is designed for safety
and ease of operation, yet is flexible enough
to allow choices when restarting a halted
batch. Three general principles govern the
operation of the switches:
