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.
