TRANSFORMERS (con't)
4. If you are replacing the Stepper Drive
Transformer, remove the four screws holding
the Load Plate, set screws and Load Plate
aside (Figure 3-71).
5. Follow each of the four wires coming out of the
Transformer and note their locations and color.
You may want to write this information down.
Note: The wiring diagram in this manual can be
used to determine transformer connections;
however it is easier to write this information
down.
6. Disconnect the ends of each wire and feed
them back through any Wire Troughs or Wire
Ties. You will probably have to cut a few Wire
Ties to do this.
7. Remove the four
Transformer to the Base Plate (Figure 3-72).
8. Note the orientation of the Red and Black
wires. Remove transformer.
9. With the replacement Transformer, orientate
Red and Black wires so that they are facing the
same direction as the old Transformer.
10. Fasten Transformer to Base Plate with the four
screws from the old Transformer.
11. Reconnect the two Red and two Black wires to
their previous locations.
Note: If replacing the Seal Wire Transformer,
you will have to terminate the Red wires with a
Ring Terminal of similar size.
12. Replace Frame Cover and Motor Cover using
screws and locking washers.
