7.4.3Temperature Monitoring/Indication
Temperature Monitoring
The temperature is measured by means of three temperature sensors. One sensor monitors the processor temperature, the second the temperature in the area of the memory module and the expansion cards and the third the temperature in the area of the power supply unit.
SIf the temperature near the power supply exceeds 45oC (fixed value), the fan is set to maximum rpms. To activate this feature, the setting “Fan Control” has to be turned on in the Setup menu (Sec. 6.1.4).
SIf the temperature exceeds one of the three temperature values of the set thres- holds, a temperature error is registered with the following effects:
Reaction | Option |
|
|
Temp LED to red | always |
|
|
Fan goes to maximum rpms. | always |
|
|
SOM application is displayed | always |
|
|
Temperature errors do not occur during the normal approved use of the device. If a temperature error occurs, check the following possible causes:
SAre the ventilation slots blocked?
SIs the fan working?
SIs the ambient temperature higher than the allowed value?
SHas the total capacity for the power supply been exceeded?
The temperature error remains saved until the temperature thresholds are again exceeded and are reset by one of the following measures:
SAcknowledge the error message via the SOM program
SRestarting the device.
