6.4.15 Operator Screens
The user screen may be selected from six
different formats that are shown in Appendix 1.
They show different information and have
different display sizes so that the operator is
only presented with the essential information
necessary to operate the batching system.
Some screens include graphical information
allowing batch progress to be rapidly
assessed.
Screen 6 is intended for commissioning and
shows all engineering information including
output status and flow rate.

6.4.16 Display
The display contrast and backlight brilliance
are adjustable using this function. The two
adjustments are made with the
Up and Down
buttons, the amplitude of each being shown on
a horizontal bargraph. Control is transferred
between brilliance and contrast by operating
the
P pushbutton.
After adjustment pressing E enters the
changes and returns the display to the System
Menu.
6.4.17 Output options
Control 1 is a dedicated output that is always
connected to terminals A1 and A2. Control 1
is energised immediately the
Start button is
operated and de-energised when the batched
volume equals the batch setpoint.
Outputs 2 and 3 may be configured to output
six different signals or they may be unused as
described in sections 6.4.8 & 9. The following
sections describe each of these selectable
signals.
6.4.17.1 Control 2
This output is similar to Control 1. It is
energised
a configurable time
CONTROL2delay after Control 1 is energised
and de-energised a configurable batched
volume CONTROL2stop before Control 1 is
de-energised. Fig. 1 shows the operation
diagrammatically.
6.4.17.2 Control 3
This output is identical to Control 2 except
delays are defined by CONTROL3delay and
CONTROL3stop.
6.4.17.3 Flow alarm
This output is described in section 6.6.7
6.4.17.4 Reset status
The reset status output indicates when the
batch has been started and when the controller
has been reset and is ready to start another
batch. See Fig 12.
Fig 12 Reset status timing
6.4.17.5 Batch status
The batch status output is the inverse of
Control 1 except that it does not close if a
pause is initiated during a batch. See Fig 13.

6.4.17.6 Pulse output
