Circuit breaker replacement
Refer to the Base Assembly parts lists and illustrations in Section 8 of
this manual for assistance as needed.
1. Turn the main electrical switch OFF at the applicator and disconnect
input line voltage from the applicator.
WARNING: Shock hazard. Disconnect the applicator from
input electrical line voltage. Failure to disconnect line voltage
from the applicator may result in a serious electrical shock.
2. Remove the electrical enclosure cover by removing the captive
screw on top of the cabinet.
3. To obtain working room, remove the white plugs along the top of the
circuit board from their receptacles on the board (there are two of
these on a Model 2302 applicator, four on a Model 2304 and five on
a Model 2305).
4. Remove the two screws which secure the control panel frame to the
base of the unit. Tilt the circuit board away from the unit until it can
be removed from the slots that secure it at the bottom of the board. It
can now be pulled away from the circuit breaker area to provide
more working room.
NOTE: Do not try to remove it entirely from the applicator because it is
still connected by several wires.
5. Remove the screws which secure the circuit breaker assembly to the
base of the applicator.
6. Pull the circuit breaker and the attached faceplate away from the
base. Remove all the wires at the six screw-type terminals and from
the one push-on terminal.
7. Remove the two screws that secure the faceplate to the breaker,
then remove the faceplate.
8. Attach the faceplate to the new circuit breaker with the two screws
removed in step 7.
9. Attach the wires removed in step 6 to the new circuit breaker in
accordance with the wiring diagram in Section 6. The line wires
connect to the top terminals and the load wires connect to the
bottom terminals. (Refer to Section 6 Table of Contents for the
correct wiring diagram.)
NOTE: Take care to wire the circuit breaker correctly. Failure to do so
may cause the applicator to malfunction or the circuit board to be
destroyed.
10. Place the faceplate in its slot in the base and secure it to the base
with the two screws removed in step 5.
11. Holding the circuit board frame so that its top is tilted away from the
applicator, match the slots in the bottom of the frame with the slots in
the base of the unit. When the keyed slots interlock, rotate the top of
the frame up and toward the unit until it is standing upright.
12. Secure the frame to the base of the unit with the two screws
removed in step 4.
