#
Reference error of a servomotor
Bit 0
Valence 1
Reference error of the fuel servomotor
The reference of the fuel servomotor was not successful.
It was not possible to reach the reference point.
1. Check if the servomotors have been inverted.
2. Check if the servomotor is blocked or overloaded.
Bit 1
Valence 2…3
Reference error of the air servomotor
The reference of the air servomotor was not successful.
It was not possible to reach the reference point.
1. Check if the servomotors have been inverted.
2. Check if the servomotor is blocked or overloaded.
Bit 7
Valence
≥
128
Reference error owing to parameter modification
The parameterization of an actuator (e.g. the reference position) has been
modified. This error will be visualised to start up a new reference.

#
Fuel servomotor error
0
Position error
It was not possible to reach the target position within the requested tolerance range.
1. Check if the servomotor is blocked or overloaded.
Bit 0
Valence 1
Circuit open
Circuit open shown on the servomotor connection.
1. Check the wiring.
Bit 3
Valence
≥
8
Curve too steep in terms of train ratio
The slope of the curve can correspond to a maximum position modification of 31°
between 2 points of the modulation curve.
Bit 4
Valence
≥
16
Deviation of section compared with the last reference
Overloading of the servomotor or servomotor subjected to mechanical torsion.
1. Check if the servomotor is blocked in any point along its range of action.
2. Check if the torque is sufficient for the application.

Short circuit of the sensor
Short circuit in the QRB sensor...
1. Check the wiring.
2. Flame detector probably faulty.

6 Fuel valve 3
The relay contacts have joined together
Check the contacts:
1. Control box connected to the power supply: the fan output must be without voltage.
2. Disconnect the power supply. Disconnect the fan. The resistive connection
between the fan output and the neutral wire is not allowed.
If one of the 2 tests fails, replace the control box because the contacts are definitively
joined together and it is no longer possible to guarantee safety.

#
Relay supervision error
0
The safety relay contacts have joined together or the
safety relay has been powered by an external power
supply
Check the contacts:
1. Control box connected to the power supply: the fan output must be without voltage.
2. Disconnect the power supply. Disconnect the fan. The resistive connection
between the fan output and the neutral wire is not allowed.
If one of the 2 tests fails, replace the control box because the contacts are definitively
joined together and it is no longer possible to guarantee safety.
