386/ATM Coprocessor User Manual
NOTE:
To extend battery life, the 386/ATM Coprocessor is shipped from the
factory with the battery switch in the OFF position. Since the system
parameters are stored in battery-backed CMOS RAM, you must run the
SETUP Utility during initial module installation or after a battery failure.
During periods of high conducted or radiated electrical noise conditions,
diskette access may cause seek and/or read/write errors. These errors do not
affect the operation of other parts of either the 386/ATM or the
programmable controller system.
It is recommended that you start up with the diskette and then switch to
the hard drive for operation. If you experience a seek or read/write error
during a diskette access, please try the operation a second time. If the
problem continues, wait for quiescent periods before performing diskette
operations.
As in any electrical installation, the potential for live circuits may
be present at the PLC and/or adjacent devices when the ultimate
protective enclosure is opened for routine service, maintenance or
programming. Accidental contact with live circuits may result in
personal injury or damage to equipment. Installation, maintenance
and programming must only be performed by qualified and
authorized personnel familiar with recognized electrical practices
and procedures in working with high voltage.
