Fuel/air ratio internal checking error: cyclical data
check
1
Check synchronisation data, different current load
2
Check synchronisation data, different target load
4
Check synchronisation data, different target positions
16
Check synchronisation data, different positions reached

#
Fuel/air internal checking error
Carry out a reset; if the error arises repeatedly, replace the
control box

Reference error of a servomotor
0
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.
1
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.

Reference error owing to parameter modification
The parameterisation 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 (the voltage between pin 5 or 6 and 2 of the
X54 connector must be > 0.5 V).
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.

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.
