2.1 Operator Controls
The BA458C batch controller may be
configured with a variety of operator display
screens. Each set of screens provides a
different level of information, some including
graphical displays. All the screens identify the
function of the front panel push-buttons which
have the following functions.
START Causes Control 1 to be energised
which will start the batch. The screen
will display ‘Running’ until the batch
is completed, or the STOP push-
button is operated.
STOP Operating this button during a batch
immediately de-energises Control 1
and Control Outputs 2 & 3 if they are
used, causing the batch to pause.
‘Paused’ will be displayed on the
screen. During a pause any input
signal continues to be counted.
The batch may be resumed at any
time by pressing the Start button, or it
may be aborted by operating the
Reset button.
At the end of each batch the Control
Output(s) will be de-energised and
‘Complete’ will be displayed on the
screen.
RESET After completion of a batch the batch
controller must be reset before the
next batch can be started.
After resetting the screen displays
‘Ready’. Input signals are ignored
until the Start button is operated.
Note: Two selectable options
modify the reset function.
Quick Restart eliminates the need
to manually reset the BA458C at
the end of each batch. When a
batch is complete the batch
controller will display the volume
that has been dispensed.
Operating the Start pushbutton will
reset the batch controller and start
another batch. See section 6.4.7
Auto Restart enables the batch
controller to run continuously. At
the end of each batch the
controller waits for a
programmable time before
automatically resetting and starting
another batch. This sequence will
continue until a programmable
number of batches has been
completed or the Stop button is
operated. See section 6.4.7
MENU Operating this button gives access
to the Operator Menu that may be
protected by a four digit security
code. This menu may be
configured to give the operator
access to any, or none of the
following functions:
Select Batch Select 1 of 9
pre-entered
setpoints
Batch Size Adjust 1 or all 9
setpoints.
Batch History Show size of last
10 batches.
Configure Full access to
the instruments
configuration
menu.
If no items are contained in the menu
the operator can only start, pause
and stop a batch. Inclusion of the
Select Batch function allows the
operator to select the batch setpoint
from one of nine pre-entered values.
To aid identification, each setpoint
may be identified by a name having
up to sixteen digits.
If included in the menu, the Batch
Size function allows the adjustment
of all the pre-entered batch setpoints
Batch History shows the size of the
last ten batches which have been
completed.
The Configure function provides
operator access to the batch
controller configuration menus
described in section 6. Entry to
these menus is protected by an
external security link between
terminals 18 and 19 and an optional
four digit security code.
