*1 The front face of the PL unit, installed in a solid panel, has been tested using conditions
equivalent to the standards shown in the specification. Even though the PL unit’s level of
resistance is equivalent to these standards, oils that should have no effect on the PL can
possibly harm the unit. This can occur in areas where either vaporized oils are present,
or where low viscosity cutting oils are allowed to adhere to the unit for long periods of
time. If the PL’s front face protection sheet becomes peeled off, these conditions can
lead to the ingress of oil into the PL and separate protection measures are suggested.
Also, if non-approved oils are present, it may cause deformation or corrosion of the front
panel’s plastic cover. Therefore, prior to installing the PL be sure to confirm the type of
conditions that will be present in the PL’s operating environment.
If the installation gasket is used for a long period of time, or if the unit and its gasket are
removed from the panel, the original level of the protection cannot be guaranteed. To
maintain the original protection level, be sure to replace the installation gasket regularly.
• When using any of the PL ís optional devices, be sure to check that
deviceís specifications for any special conditions or cautions that may
apply to its use.
• Be aware that not only does the Hard Disk have a fixed lifetime, but that
accidents can always occur. Therefore, be sure to back up your Hard
Diskís data regularly, or prepare another Hard Disk unit that can be used
for backup.
• The Hard Disk lifetime given here may be reduced due to unforeseen
environmental factors, however, generally speaking, the disk should last
for 20,000 hours (of operation) or approximately 5 years, whichever
comes first at an operating temperature of 20
o
C and 333 hours of
operation per month. (HDD access frequency of 20% or less)
• Using the Hard Disk in an environment that is excessively hot and/or
humid will shorten the diskís usage lifetime. A wet bulb temperature of
29
o
C or less is recommended. This is equivalent to the following data.
• In order to extend the lifetime of the hard disk, Pro-face recommends you
set the Windows
®
2000 [Control panel]-[Power Management option]-
[Turn off hard disks] selection / the Windows
®
XP [Control panel]-
[Power and Maintenance]-[Power Options]-[Power Schemes]-[Turn off
hard disks] selection to turn the hard disk off when the unit is not being
operated. A setting of 5 minutes is recommended.
