Vulcan VC4G / VC6G gas convection ovens (computer control)
Full-size gas convection ovens. On the computer control a fault code alternates with the cavity temperature on the display; normal running resumes once the cause is gone.
What it is: Convection oven. Error codes apply to the VC4GC and VC6GC computer control. Manual-control models have no codes.
Vulcan VC4G / VC6G gas convection ovens (computer control) error codes
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| Er01 / Er02 | ROM / RAM check failed | Internal control fault | Switch off and on. |
| Er03 | Ambient sensor error | Control area below 0 °C | Check the temperature at the control. |
| Er04 | Configuration error | Control fault | Switch off and on. |
| Er05 | EEPROM error | Power lost while saving | Switch off and on. |
| Er06 | Zone 1 reading too low | Wrong sensor type set, or temperature outside range | Check setup parameter InP1 matches the sensor; check for a reversed or open probe. |
| Er07 | Zone 1 reading too high | Open sensor | As above. |
| Er10 | Stack overflow | Control fault | Switch off and on; check the sensor wiring. |
| Er11 | Open sensor | Probe or wiring open | Check InP1 and the probe. |
| Er12 | Shorted sensor | Probe shorted or wrong type | Check InP1 and the probe. |
Notes
- Electrical noise, moisture, heat or vibration can also cause these codes if no other cause is found.
