Sharp SX 1075

TRANSFORMERS
The Sharp SX
TM
Bagger uses two “Step-Down”
transformers. One is used for the Seal Wire and the
other is used for the two TM4500 stepper drives.
They are each 0.365 KVA transformers with a
120(P):28(S) voltage ratio. Only replace with equal
or greater KVA rating and same voltage ratio.
1. Remove the two rear screws and the two front
screws holding the Motor Cover. (Figure 3-58
and Figure 3-59)
2. Remove Motor Cover and set aside.
3. Remove the four screws holding the Load
Plate, set screws and Load Plate aside (Figure
3-60.)
4. Locate the transformer you wish to
troubleshoot and proceed to that section
(Figure 3-61).
Note: Transformer locations will change
depending on your version of the SX. The
Stepper Drive transformer’s wires terminate in
a terminal block. The Seal Wire transformer is
connected to the Solid State Relay and Seal
Wire.
