” button shows that the current state is OFF and it is touched
afterwards, the hint information on the button will change to “ON” meanwhile the start-up

“Remote Monitoring”
: When main module, communication module and monitoring
computer are connected with each other correctly and software for remote monitoring is
executed, “

communication paused, the “
Remote Monitoring

“Shield Touch Screen”:
It means the touch screen has been shielded and all parameters
cannot be set up unless by the “shielding/cancel shielding” operation of remote monitoring.
“Quick Test”
:
It means the touch screen enters into a quick testing status. This is only
used for tests in the factory.
The above-mentioned “Remote Monitoring”, “Error”, “Shield Touch Screen” and “Quick
Test” are not command buttons, but indications of events that occur to the touch screen.
Note: Touch screen takes 1 minute to save the set data, which means the set data or
change of command will be saved to FLASH inside the touch screen after 1 minute. If power is
off right after the setting, then the set data won’t be saved because there is not enough time for
saving, in which case, touch screen will still operate and display according to the previous
parameters when it is re-energized.
