MONITORING OF WARNINGS AND/OR FAULTS
Lock-outs:
E:01
=
Flue gas sensor shorted (X8-2/X8-7)
E:02
=
Flue gas sensor interrupted (X8-2/X8-7)
E:03
=
Fan speed deviation on ignition.
Appears when, after 4 start attempts the start is interrupted due to an excessive deviation of the actual speed from
the setpoint speed setting.
E:05
=
Flow temperature sensor 2 shorted (X8-3/X8-8)
E:06
=
Flow temperature sensor 2 interrupted (X8-3/X8-8)
E:07
=
Flow temperature sensor 2 lock-out temperature exceeded
Appears if the lock-out temperature of 110°C is exceeded on flow sensor 2.
E:08
=
Flow temperature sensor 1 lock-out temperature exceeded
Appears if the lock-out temperature of 110°C is exceeded on flow sensor 1.
E:09
=
Difference between flow sensors 1+2 too high
Appears if the difference between the two flow sensors exceeds 10°C.
E:10
=
Flow temperature sensor 1 shorted (X8-1/X8-6)
E:11
=
Flow temperature sensor 1 interrupted (X8-1/X8-6)
E:12
=
Internal error in automatic firing device
E:13
=
Parameter loaded
After a parameter set is loaded on the automatic firing device, the boiler is locked automatically. After pressing “re-
set”, boiler operation can be resumed.
E:14
=
Parameter loading error
A connection error has occurred when loading the parameter using SITBIC960lab. The process should be repeated.
E:15
=
Internal error in automatic firing device
E:16
=
Water pressure too high
Appears if the water pressure limit set under Parameter 23 is exceeded.
E:17
=
Internal error in automatic firing device
E:18
=
Fan rotation below limit
Appears if the number of fan rotations falls below the reference value for 30 seconds or in case of a defective fresh
air damper (option to UG (1700D)).
E:19
=
Fan rotation above limit
Appears if the number of fan rotations exceeds the reference value for 30 seconds.
E:20
=
Flame interruption during operation
Appears if the ionisation falls below 1.5
µ
A more than three times during one single heat demand. With the boiler
type UltraGas (15-90) the threshold value is being increased to 2.5
µ
A on-site for monitoring the ionisation.
E:21
=
No flame after ignition
Appears when no flame is detected after 4 ignition attempts or in case of a defective fresh air damper (option from
UG (2000D)).
