BATCH PROCESSING MODE
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 Setpoint,
flow will start immediately. If not, press
SETPT
to
select a Setpoint.
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 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
.
- 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 stop flow with a batch in progress, clear the
Setpoint and press
SET
.
If the Batch value is changed while a batch is in
progress, the new Batch value is used when
SET
is
pressed.
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 Setpoint 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 Setpoint 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
Setpoint, flow will immediately resume, and the Totalizer counter will continue
per the user established Setpoint flow rate.
