Touchscreen Interface Buttons - Gilson AC-250 Operating Manual

6.2 Touchscreen Interface Buttons

• JOG ADVANCE: This allows the user to jog advance the main ram. The ram only moves while the button is
being pressed. Therefore, the button must be held to advance. Releasing the button will stop the advance
and hold the ram in position. The button is green while being pressed and yellow when holding.
• RETRACT: This allows the user to retract (dump hydraulic pressure). Pressing the button will open the valve
and dump all system pressure. It does not need to be held—a single press dumps the system.
• START TEST: When a test is ready, press this button to start the test. During preload, this button will be yellow.
When a test is running, this button will be green.
• STOP TEST: During preload, a running test, or while paused, the "Stop Test" button can be pressed to stop
the test. Pressing the button will stop the motor and open the dump valve to dump all system pressure.
• TARE LOAD: This allows the user to tare or zero the system load/stress.
• SHOW GRAPH: This shows a graph of the test when pressed. Button changes to "Hide Graph" when a graph is
displayed. Press the button to close the graph in this state.
• DIAGNOSTICS: This allows the user to see the status of the "E-Stop" button, the VFD Drive, the pressure
transducer, and the over-travel limit switch. The diagnostic button will show red if there is a problem or an
activated item. Pressing the button brings up the screen below. A green indicator means the item is ready,
while a red indicator means that the item is in a fault condition. You need to resolve any faults to achieve a
green "System Ready" before you can proceed with testing.
The diagnostics screen for your system may have additional items to accommodate special features, such
as MOE, secondary frame, or displacement.
• USER INFO: This allows the user to enter and store various names, companies, addresses, and other reporting
information. Select the check box "Print Each Test" to print a report at the end of each test. This report is a
detailed specimen report that includes a graph of Load vs. Time. For machines with other options, like MOE,
additional graphs are included in the printed reports.
