Introduction
Service Mode
Only qualified service personnel should operate the unit
when either the front or rear panels are open. Potentially
lethal high voltages are continually applied to the circuit
boards and other areas within the unit during its operation.
Failure to follow this precaution may lead to severe injury
or death.
The Service Mode of the MS-40 is intended for use by
qualified VIC personnel or Users specifically trained
by VIC. Under no circumstances should any individual
be assigned access to this mode without a thorough knowledge
of vacuum systems as well as the MS-40 System. Use by an
unqualified operator may result in damage to the unit
and/or personal injury.
NOTE: In Service Mode the MS-40 may be operated as a
totally manually operated and sequenced leak detector. In this
mode the vacuum system of the unit operates without its
normal computer protected safeguards. Contamination
and/or damage to the unit will occur if the vacuum system
is not properly sequenced. If in any doubt, operate the
various valves and controls that comprise the vacuum
system in the same sequence as the MS-40 operates in its
standard/fully automatic mode.
