Errors which can be Detected by RAS Features
Power Voltage Alarm
Monitors the status of the PL unit’s built-in power supply and internal CPU power supply.
Cooling Fan Rotation Alarm
Monitors the CPU cooling fan and electric fan RPM speeds.
Internal Temperature Alarm
Monitors the internal temperature of the PL unit and the ambient temperature of the CPU.
Configure the settings via [System Setup] to enable/disable individual monitoring features, and the monitor-
ing levels for voltage, fan and temperature. After that, enable/disable individual monitoring features via the
System Monitor feature.
Watchdog Timer Timeup
This feature monitors the performance of the CPU by writing the CPU’s time-up count value to the RAS fea-
ture’s built-in programmable timer and by periodically clearing the count value from the CPU. Errors are
detected when the clearing of the count value from the CPU stops, which will cause a timer overflow.
Use the System Monitor Property area to set the Watchdog Timer Timeup ON or OFF, and enter detailed error
processing settings. For the method for using the Watchdog Timer from a user application, refer to the API
Reference which can be downloaded from the Pro-face support site “Otasuke Pro!”.
Touch Panel Alarm
Detects Touch Panel alarms. When an alarm occurs, the LED will turn orange.
Backlight Alarm
Detects Backlight alarms. When the backlight burns out, the LED will flash orange/red.
SMART Alarm
Monitors the status of the hard disk. Detects a warning of trouble of the hard disk.
• A CF card doesn’t support SMART and therefore the status of the CF card cannot
be monitored.
• When a hard disk except options made by Pro-face is used, the operation of
SMART Monitoring cannot be guaranteed.
