5.
Connect power to machine.
6.
Verify incoming AC line voltage at the line service
connection point.
7.
Verify incoming voltage is present to primary side
of transformer 1T.
8.
Measure output AC voltage across secondary
windings of transformer. Voltage should be
approximately 120VAC.
A.
If voltage is present, transformer is
functioning.
B.
If output voltage is not present, verify
transformer wiring connections.
1)
If connections are correct, replace
transformer.
C.
If output voltage is low, disconnect power
from machine.
1)
Disconnect one side of the secondary.
2)
Apply power to machine.
3)
Check output voltage across
secondary windings.
a.
If voltage is still low, replace
transformer.
b.
If voltage is approximately
120VAC, check components and
related wiring connected to the
secondary.
TRANSFORMER 2T - TEST
Certain procedures in
this section require electrical test or
measurements while power is applied
to the machine. Exercise extreme
caution at all times and follow Arc Flash
procedures. If test points are not easily
accessible, disconnect power and
follow Lockout/Tagout procedures,
attach test equipment and reapply
power to test.
1.
Remove FRONT COVER.
2.
Open control door.
3.
Remove right side cover.
4.
Connect power to machine.
5.
Verify incoming 120VAC voltage is present to
primary side of transformer 2T.
Fig. 9
A.
If 120VAC is not present, check fuse F2 on
relay board.
1)
If fuse is good, perform
TRANSFORMER 1T - TEST.
6.
Measure output AC voltage across secondary
windings of transformer. Voltage should range
between (11.5 - 16VAC).
Fig. 10
A.
If voltage is present at output, transformer is
functioning.
B.
If voltage is not present at output, verify
transformer wiring connections.
1)
If connections are correct, replace
transformer.
C.
If voltage is low, disconnect power from
machine.
1)
Disconnect one side of the secondary.
2)
Apply power to machine.
3)
Check voltage across secondary
windings.
