TRANSFORMER 1T - 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.
NOTE:
Transformer 1T steps down incoming line
voltage to 120VAC for use by the machine's control
components.
1.
Remove FRONT COVER.
2.
Open control door.
3.
Remove right side cover.
4.
Verify transformer is strapped correctly by
comparing connection wiring points on
