Touchscreen Operation

The system is provided with a graphical touchscreen display. This allows an operator to see the state of the machine at a glance. The surface of the screen is touch sensitive allowing an operator to reset counts, view other pages and alter settings if required.

To change the page being displayed, touch the PAGE button on the screen.

This is a typical page displayed during normal machine operation, in this case the machine is an 8 channel leak detector. The system will always show this page after power-on. It has been designed to display all the information routinely needed by operators or quality control staff, i.e. bottle counts and test results. This example page displays the following types of information:

The system provides counters of various items. A count can be reset to zero as follows:

This type of display shows the magnitude of a value as a bargraph scale. This give a quick graphical indication of a value, allowing rapid appreciation of trends and quick comparisons to other channels. In the above example the bargraphs show the air pressure inside 8 bottles being leak tested. (More accurate numeric displays are available on separate diagnostic pages if required.)

These are turned on and off as required, and can be used to indicate ON/OFF, ENABLED/DISABLED, PASS/FAIL type conditions. In the above example the FAIL indicator turns on when a bottle fails the test.

Also provided are red and green LED indicators, separate from the graphical touchscreen. These are under software control and can be used for various functions depending on the machine.

For a leak detector, they would typically be used to indicate passes and failures during a test.

To the right of the indicator light, in the example above, is displayed a number representing the precise result of the leak test. This number is compared against the set limit to determine pass or fail.

Machine settings are usually grouped onto separate pages from the main display screen, so that operators do not accidentally make changes.

There are two types of setting; numerical and on/off. A value of a numerical setting is indicated by the number displayed. The value of an on/off setting (i.e. whether it is on or off) is indicated by an indicator box. To alter a setting, proceed as follows:

Touch the displayed setting value. The value should become highlighted.

Touch the “ADJ UP” button (increase) or “ADJ DOWN” button (decrease) as required. Alternatively, the setting can be returned to its factory set value by pressing the “R” (reset) button.

Press the “OK” button to retain the new value.

This page is used to group miscellaneous settings that may not be present on all machines. It also allows seldom used screen pages to be switched on and off, to avoid confusion.

In the example above, the operator simply touches the light for “Splitter Enabled” to switch between the enabled and disabled states of the “Splitter” (shown by the indicator being on and off respectively).

The last two lines control whether the I/O Page and the Diagnostics page (see below) are displayed. Again, to enable or disable display of a page, simply touch the indicator box.

NB Once a page has been switched on, it will not be removed from the display until the next power-up of the system.

See the Machine Input / Output Sheet (supplied separately from this manual) for details of the function of each input and output.

The state of each I/O is shown by an indicator box being lit (for on) and unlit (for off).

The state of an output or input can be over-ridden from this page as follows:

Touch the indicator box corresponding to the input or output which requires forcing.

To force on, press “ADJ UP”. The indicator will change to “1” to show it is forced on.

To force off, press “ADJ DOWN”. The indicator will change to “0” to show it is forced off.

To reset to normal operation, press “R”.

Ensure that no I/O’s are left forced to 0 or 1 when normal operation is to be resumed. If in doubt, power-off and on to reset the system.
