Error Code

Message

Cause/Correction

101

CAN bus fault detected

Hardware error. Check the CAN cable for shorts. If the cable is good, replace the PC104 CAN card.

102

CAN receive buffer overflow

Host CAN interface received too much data and could not process it quickly enough. Reboot the system.

103

Message timeout

Remote CAN device did not respond to a direct request in the allotted time. Check the gun card or iFlow card.

104

Went offline

Normal operational message. The user will see this message if the booth exhaust fan is shut off, which removes power from gun cards, or if the gun card is disconnected, or if the iFlow module is disconnected from the CAN network.

105

Returned to online

Normal operational message. No action required.

107

Communications errors

These error messages indicate that communications on the iControl CAN bus may be having problems. Troubleshooting should include verification of all CAN cable connections and grounding, and gun cable connections and continuity. CAN errors can also be caused by individual gun cards or the iControl PC to PC104 card interface. These errors do not indicate a specific device failure as all devices are in parallel on the CAN bus.
