This is your Title Block, found at the bottom of each page. All the information you need about the page you are on can be found here.
Following a Pathway1)When reading the schematics it is important to know where your cable is going next. This will always be indicated with an arrow followed by the voltage/the page number.
2)120.2This tells you this cable resumes on page 120 in section 2.
3) The sections are outlined at the top of each page. So if you turned to page 120, you would find this cable resume in the area shown. The cable will be labeled by the page and section it came from.

Basic Troubleshooting
ToolsA Multi-Meter is needed to assess and trouble shoot problems in your Electrical Schematics. If you are unfamiliar with using one please refer to this link.

Baler 24V DC Circuit
The 24V DC Circuit originates at a Transformer shown on the left. To trouble shoot, test for power before and beyond this transformer. If neither seem to be the source of the problem, then follow the 24V cable through your schematics, testing for power until you are able to pinpoint the location of the deficiency.
24V Transformer
110V AC Circuit (Aux)
Transformer where power transfers from 480V to 110V
To trouble shoot, check for power before and after transformer. If the problem is not located, continue to check your 110V AC line until you find a deficiency.
Thermal OverloadWhen a light indicates a thermal overload, check which terminal has been tripped. The knob below will be flicked to the side indicating that it is the terminal that overloaded.
Visual Representation
This is your E-stop Indicator. It has 4 lights. Refer to the following circumstances…
1 light on: The E-stop has power
2 lights on: Circuit 2 is not closed
2 lights on: Circuit 1 is not closed
4 lights on: No deficiencies, E-stop is reset.
