Fan; Id Information Indication - Omron NX Series Hardware User Manual

3 Configuration Units
Cause of error
One of the following was detected at pow-
er ON.
•
Built-in capacitor discharged
•
Battery not mounted
•
Mounted battery discharged
One of the following was detected after
power ON.
•
Battery was removed
•
Mounted battery discharged
When you mount the battery, set the Battery-related error detection to Use.
The measurement of clock data starts from January 1st, 1970 if the clock oscillator stops. If this oc-
curs, readjust the CPU Unit's clock data to the current time.
In order to use the clock data for programming, you need to use system-defined variables to read the
presence or absence of the Low Battery Voltage and Real-Time Clock Stopped errors and confirm that
the clock data is normal.
Refer to the Sysmac Studio Version 1 Operation Manual (Cat. No. W504) for battery-related error de-
tection and clock data settings.

Fan

The fan is built into the CPU Unit to cool the CPU inside the CPU Unit.
The built-in fan cannot be replaced. The life of the fan is shown below.
Life
Storage period during no power supply 1 year
Precautions for Correct Use
If the fan built into the Controller has not been operated for more than 0.5 years, make sure that
there is no Controller error related to the fan when the power is supplied.
