14. CNC DISPLAY UNIT WITH PC FUNCTIONS
286
When CNC display unit with PC functions is used, the following
environmental conditions (as measured top of the CNC display unit with
PC functions inside the cabinet) must be ensured for the CNC display unit
with PC functions unit installation.
Ambient temperature Operating : +5 to +45_C
Non–operating : – 20 to +60_C
Change in temperature Up to 20 _C/hour
Ambient relative humidity Standard : 10 to 75% (non–condensing)
Short–term : 10 to 90% (non–condensing)
(within one month)
Vibration Operating : Up to 0.5G
Non–operating : Up to 1.0G
Environment Installed in a hermetically sealed cabinet
Altitude Operating : – 60m to 1000m
Non–operating : – 60m to 12000m
*1 Ambient temperature during operation :
The temperature sensor on the CNC display unit with PC functions
PCB monitors whether the temperature is within the specified range.
1) If the temperature at power–on is beyond the allowable range only
CNC/PMC is started. After that if the temperature becomes to
within the allowable range, CNC display unit with PC functions
automatically starts.
This function is disable when Option for Non–Connecting with
CNC is ordered. CNC display unit with PC functions starts up
irrespective of the temperature. Therefore, the temperature around
CNC display unit with PC functions should be watched by the
other method.
2) If the temperature drifts out of the allowable range after normal
activation, an error occurs when the hard disk is next accessed.
*2 Vibration :
The CNC display unit with PC functions unit and built–in hard disk
drive may suffer resonance at certain frequencies. Careful checking is
required on the CNC display unit with PC functions unit has been
mounted on a machine.
CAUTION
If an operation error or mishap occurs, the data on the hard
disk may be lost, even if all the installation conditions are
satisfied. Therefore, always maintain a backup copy of the
data on the hard disk in case the stored data is lost or
damaged.
Especially, the power–off on accessing the hard disk must
not be done because that possibility is very high. Please
concern for the end–users.
