Vdc Power Supply - Sharp SX 1075 Service Maintenance Manual

24 VDC POWER SUPPLY

TM
The Sharp SX bagger uses a single 24 VDC
power supply for all sensors, relays and control
components. This section will explain how to
troubleshoot and if necessary, replace the power
supply.
TESTING
The symptoms of a non-functioning Power Supply
are easy to spot. The "Bag Open Cage Fan" and
"Cabinet Cooling Fan" are not powered by the 24
VDC power supply. If when powering up a
machine, the fans can be heard running, but the
rest of the system is unresponsive, The Power
Supply is most likely defective. If a machine is
completely unresponsive, refer to the section on
checking and replacing fuses.
1. Plug machine in but do not turn on.
2. Remove any bags in the machine web path
and remove bag roll.
3. Remove the two rear screws and the two front
screws from the Motor Cover (Figure 3-21 and
Figure 3-22).
4. Remove Motor Cover and set aside.
5. Locate the 24 VDC Power Supply.
Note: The Power Supply location changes
depending on your version of the Sharp SX
Bagger. The wiring however is exactly the
same.
