Power Down
The system can be shut down using any of these methods. After the switch is powered down, the pilot light will
be amber unless the switch has shut down automatically due to a fault condition
Keylock must be in operate position for all of these methods to work;
“hibernate” and “sleep” are invalid Desktop Start menu options for this system;
if pushbutton on/off is held for less than 6 seconds, nothing will happen.
Power-Button Initiated
Press and hold the front panel powerbutton for more than 6 seconds.
This initiates a graceful shutdown of the chassis (and Touchscreen PC, if present).
Software-Initiated by MagentaControl Software or Optional Touchscreen
From the
Touchscreen’s Magenta control GUI: Select “System Shutdown” button.
From the Windows desktop
menu, select “Start” then “Shutdown”
Either one of these initiates a graceful shutdown of the chassis and Touchscreen PC.
Self Initiated
The internal status & safety monitoring software routines may initiate a system shutdown in some cases.
For example: an over-temperature condition, or a failed power-supply rail. No user-intervention is
required for this automatically initiates shutdown.
This initiates a graceful shutdown of the chassis (and Touchscreen PC, if present).
Hard Shutdown
If none of the above methods work (due to a system error or other reason), it is certainly possible to
force the system off immediately by using the AC-mains switches on the back of the chassis. Note that
BOTH power supplies will need to be turned OFF for the system to be shut down completely.
A hard shutdown
can
cause corruption of data, or possibly even render the Touchscreen
PC unbootable. Usually the Windows operating system can recover from a hard shutdown,
but it is not unusual for this event to cause temporary or permanent problems with the OS or
registry.
There is no “!A01<” unsolicited message transmitted when a hard shutdown is used.
For all the “graceful” shutdown methods, the following sequence of events take place:
Front-panel power-status indicator (near pushbutton) turns red.
The Touchscreen PC (if present) immediately exits the UI software (or any other program) and begins a
graceful Windows shutdown.
When the Windows shutdown process is complete, the Touchscreen PC turns itself off.
If Windows requires any kind of S/W updates during the shutdown process, this can add a considerable
amount of time to the overall shutdown process. The chassis will NOT shut down until the PC has
completed whatever updating tasks are in progress.
The backplane logic proceeds to turn off all DC power rails.
The front-panel power-status indicator turns amber.
System is now fully in the off state.
If the Touchscreen PC (or external device) is not able to shut down (Windows can sometimes hang for a variety
of reasons), the backplane logic will maintain all system power ON indefinitely.
Windows may hang, or take an unacceptably long time to shut down (for a variety of reasons). In this case, then
only way to clear this condition is to switch OFF the main AC supply switches on the rear of the chassis.
