Issue
Resolution
Missing Device
Oven
Board did not report to Oven
Controller at startup.
Check power to board. Check CAN
connections. Contact ABB.
Mismatched Device
Oven
Board identity does jot match
configuration file.
Contact ABB. Check configuration file.
Inaccessible Device
Oven
Board communication not viable.
Check CAN connection to Wago module.
Refer to Wago documentation.
Duplicate Device
Oven
Two devices have the same CAN
node ID.
Correct by changing the node ID of one of the
duplicate boards.
Extra Device
Oven
A board that responded to the
Oven Controller is not listed in the
system configuration.
Contact ABB for more information. Remove
board.
PIC Comm Error
(Hardware Error)
DTC#
DSP and PIC supervisor have
stopped communicating.
Replace DTC Digital PCB.
Broken valve
(Hardware Error)
DTC#
Valve railed startup test.
Check solenoid block cable. Replace faulty
solenoid if problems persists.
AC Fault (Hardware
Error)
DTC#
DTC did not detect AC or power to
heater failed.
Check AC connections to DTC assembly. T-
Rating faults can also cause this symptom.
Current out-of-range
(Hardware Error)
DTC#
Internal power test failed.
Check heater(s) to verify proper resistance.
Check heater connections.
CAN node not found
DTC#
Device did not communicate with
Oven Controller or go online.
Check board LEDs for error.
Lost CAN heartbeat
DTC#
Device stopped communicating.
Check board LEDs for error. Check CANbus.
Code download error
DTC#
Failed to send executable code to
device.
Check board LEDs for error.
Unexpected heater
voltage
DTC#,
Isothermal
oven
Internal power test failed.
Can be a result of PIC supervisor shutdown or
T-Rating failure. Verify heaters and
temperature feedback. Check for other
faults.
T-Rating mismatch
DTC#,
Isothermal
oven
System information does not
match DTC internal setting.
Contact ABB.
Low air or carrier
pressure
DTC#,
Isothermal
oven
Air or carrier pressure switch is
open.
Verify proper air or carrier pressure and
increase if necessary. If pressure is correct,
replace switch.
Temperature reading
invalid
DTC#,
Isothermal
oven
DTC unable to read temperature.
Replace temperature probe. Possibly replace
DTC Digital Board.
CAN node not found
