Recommended Action
If your country voltage option is present, go to step 2 .
If your country voltage option is not present, contact hospital
maintenance staff and try another outlet .
If each fuse (see CV Table) is good, go to step 3 .
If either fuse (see CV Table) does not have continuity,
replace the fuse .
If 24VAC is present, go to step 4 .
If 24VDC is not present, check the 25 Amp fuse in the fuse
holder on the red wire from the transformer . If bad, replace
the fuse .
connection going to the transformer for (see CV Table) VAC .
If no voltage, follow the cable and repair or replace the
damaged component .

the transformer .
If 30VAC is present, go to step 5 .
If 30VAC is not present, check the power cable quick
connection going to the transformer for (see CV Table) VAC .
If no voltage, follow the cable and repair or replace the
damaged component .

If fuse is good, replace CPU/Power board .
If fuse does not have continuity, replace the fuse (Littelfuse
