BATCH PROCESSING MODE – CONTROLLERS ONLY
Batch mode is a function within the optional Totalizing mode. Batch mode is
designed to provide repeatable, finite flow quantities.
To activate Batch Mode:
Press
BATCH
. Then use
SELECT DIGIT
to move the arrow to the desired digit,
and the UP and DOWN buttons to change the value.
Press
CLEAR
to return to zero. Press
SET
to record
your value. If the controller has a non-zero Set-Point,
flow will start immediately. If not, press
SETPT
to
select a Set-Point.
Batch values can also be established via RS-232/RS-485
communication using Register 92. (See RS-232/RS-485
Section of this manual for serial communication methods.)
Note:
While the Totalizer counter will still reset across
power cycles, the Batch process value is stored in EEPROM and will remain valid
until updated by the user.
While the Batch is processing, the remaining amount of the Batch value is
displayed above
REMAIN
on the Totalizer screen. Time elapsed during the Batch
processing is displayed below the totalizing counter. Press
TOTAL/TIMER
to
toggle these values.
When the active Totalizer reaches the preset Batch value, flow ceases, and
REMAIN
updates to
Done Batch
. The Totalizer timer also pauses.
- To start a new batch of the same size,
simply press
RESET. The Totalizer can reproduce any number of
fixed Batches in this manner.
- To start a smaller batch,
decrease the Batch value.
The new batch begins when you press RESET.
- To continue the existing batch to a larger total
volume,
increase the Batch value. Flow resumes as
soon as you press OK in the Batch Value screen.
- To start a larger batch from scratch,
first clear the
flow Set-Point to zero to prevent unwanted flow.
Then increase the Batch value, and select a flow Set-Point. Flow will begin when
you press
SET
in the Set-Point screen.
- To cancel a batch in progress,
clear the Set-Point and press
SET
.
Note:
Batch mode operates independently of the desired flow rate, but requires
a non-zero flow rate to run. The rate of flow is determined by the controller
Set-Point value, which is established by the user via analog, front panel or serial
communication methods. Batches can be produced more slowly or more rapidly
as determined by the user-selected Set-Point flow rate.
To turn off Batch Mode:
Set the Batch value to zero (0.0) via the front panel or
RS-232/RS-485 communication using Register 92. If there is a non-zero flow Set-
Point, flow will immediately resume, and the Totalizer counter will continue per
the user established Set-Point flow rate.
