Further Checks
Unit alarms with the
following message on
LCD:-
‘PIC: +/-12V Out of
Spec.’
(Filtered Voltage),(Code
Line Failure), 0,0
The PSU Board PIC software
has detected that the +12VR or -
12VR rails are operating out of
spec.
Check and isolate faulty supply.
Fault is most likely to be on the
PSU Board or the Main Board.
Fault could also be caused by
input voltage to IC18 or IC19 on
PSU board going to low and
therefore causing the regulators
to dropout. This could be caused
by excessive current drawn on
the +12VV supply or
interruptions to the input supply
caused by erroneous operation
of supply switch TR10.
Unit alarms with the
following message on
LCD:-
‘PIC: Incompatible SW
Version
0, (code line failure),0,0
The software has detected an
incorrect PIC software version to
run with Main Board software.
Check Main Board and PSU
Board PIC software compatibility
