5 .• 10 SERVICE CHECKS AND CHECKOUT PROCEDURES
(FIG.URE 5-2)
Continued problems with the 2025 power
supplies could be an indication that:
1.
Line in use is out of specification.
The voltage must be within ±103 of
rated input line voltage..
(See
Physical Planning Manual, Form
C22-6820,, for complete requirements .. )
2..
Transformer taps set for wrong line
voltage..
If the voltage is ever
changed, the correct Feature Bill of
Material should be ordered through
Plant Field Engineering.
These
B/~s
contain complete instructions for the
2025 conversion as well as the correct
voltage nameplate tags.
The voltage
nameplate must always reflect the
voltage for which the machine is wired.
When the B/M is ordered and installed,
Machine Level Control Department is
advised of the change in the machine
voltage wiring.
3.
On thermal failures, check blowers and
filters for sufficient air flow.
Room
temperature can also be a factor.
