MAINTENANCE
The ProDrive features extremely high reliability. This is achieved through the simplicity
of
the mechanical
design and the extensive use
of
microelectronics. These drives are designed for fast, easy subassembly
replacement with no adjustments, greatly reducing the amount
of
downtime for unscheduled repairs.
6.2
MAINTENANCE PRECAUTIONS
Observing the following precautions during service activity will help avoid damage to the drive and personal
injury to the service technician.
a)
Do
NOT
open
or
remove the metal bubble
or
its seals.
b)
Do
not lift the drive by the faceplate
or
the PCB.
c) A void harsh shocks to the drive at any time.
d)
Do not move the drive for 20 seconds after DC power is removed; this ensures that the actuator is
completely locked.

MAINTENANCE LEVELS, EQUIPMENT AND SPARES
LEVELS OF MAINTENANCE
Corrective maintenance on the drive requires certain minimum levels
of
technical expertise and facilities.
Capabilities in this area will vary greatly from user to user. Maintenance procedures for the
ProDrive are
categorized in two levels.
The
first level involves on-site exchange
of
subassemblies
or
the drive itself.
The second level
iriVolves service center and/or factory repair or refurbishment
of
assemblies and the printed
circuit board.
6.4.1.1
Level
1
Unit replacement, circuit board exchange, external shock mount subassembly replacement.
6.4.1.2
Level
2
Level I plus major disassembly and refurbishment
of
the drive and repair
of
circuit boards.
NOTE: A user's service activity should be limited to
Levell
procedures during the warranty period. The
Quantum warranty is null and void
if
any Level 2 procedure has been attempted. In addition, no
repairs are authorized within the HDA. All time and material required to restore the drive to
working order will be billed at prevailing rates.
