Voltage back-feeding from manual controls

When your C220 receiver’s LED light alternates between blue and red, it’s possible that the receiver has detected power being fed back into one of its outputs and is shorted to battery. This happens when there is back feeding from a manual control that’s wired in parallel with an output on the C220.

You can access diagnostics mode on your Aarcomm remote (H212 handheld remote or S111 Belly Pack Lite) to troubleshoot the issue.

Once you’ve accessed diagnostics mode, you can troubleshoot the issue on the I/O Status (Page 1) and Error Summary (Page 2) pages.

• I/O Status (Page 1): This page shows the real-time status of each output or input, as well as the battery voltage of the C220:
• • OFF: No voltage is detected
  • ON: Voltage is detected (most likely shorted to battery)
• Error Summary (Page 2): This page shows a summary of the issue (if applicable) and a log of each error. The information is updated in real time.
  • SB: Short to battery
  • SG: Short to ground
  • OC: Over-current
  • OT: Over-temperature

Determine which outputs are back-feeding

To determine which outputs are back-feeding:

1. Power on all machine systems for normal operation, including the C220 receiver.
2. Using manual or alternate controls on your machine, cycle through all available functions. Doing this ensures that the C220 has a chance to detect all possible conflicts caused by manual controls. The LED light on the C220 may flash, which indicates that it’s detected an error condition on the outputs.
3. On your Aarcomm remote, access diagnostics mode to check the details of the error on the Error Summary page. The top screen shows the error summary and the bottom screen shows which outputs have errors. Aarcomm’s support team can use this information to determine if your system needs custom modifications for production use.
