23 # Gas pressure switch-min (Pmin) / heavy oil direct start
0 No minimum gas pressure
Check wiring to see if there is an open-circuit (X5-01)
1 Gas shortage – start prevention
Check wiring to see if there is an open-circuit (X5-01)
2 Heavy oil direct start
Check wiring to see if there is an open-circuit (X9-04) Check that the oil is preheated correctly
50 # Internal error Make a reset; if error occurs repeatedly, replace the unit 51 # Internal error Make a reset; if error occurs repeatedly, replace the unit 55 # Internal error Make a reset; if error occurs repeatedly, replace the unit 56 # Internal error Make a reset; if error occurs repeatedly, replace the unit 57 # Internal error Make a reset; if error occurs repeatedly, replace the unit 58 # Internal error Make a reset; if error occurs repeatedly, replace the unit 61 Fuel Chg # Fuel changeover Fuel Chg 0 Fuel 0
No error - change to Fuel 0
Fuel Chg 1 Fuel 1
No error - change to Fuel 1
62 Fuel Err # Invalid fuel signals / fuel information Fuel Err 0 Invalid fuel selection (Fuel 0 + 1 = 0)
Check wiring to see if there is an open-circuit 
Note Curves cannot be set.
Fuel Err 1 Different fuel selection between the µCs
Make a reset; if error occurs repeatedly, replace the unit
Fuel Err 2 Different fuel signals between the µCs
Make a reset; if error occurs repeatedly, replace the unit
Fuel Err 3 Invalid fuel selection (Fuel 0 + 1 = 1)
Check wiring for short-circuit
