Configuration
to protect the wire from overheating, not to protect the connected
device.
Some devices draw more current under circumstances such as high or
low battery voltage. Also, a motor will draw increased current when
under more load. Set a good margin and where possible check the
Output Load value under these varying circumstances.
Configuration of an output will create a number of channels, some of which
are transmitted via CAN. OutputName.Status channel is used for output
status information on CAN. The output should be on for any non-zero value.

Fault Indicator
When an output fault occurs the PDM sets the value of the Global Error
channel to TRUE (PDM.Global Error). A fault indicator light can be connected
