Recommended measures
It was not possible to reach the target position within the
requested tolerance range.
1. Check if the servomotor is blocked or overloaded.
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).
The slope of the curve can correspond to a maximum position
modification of 31° between 2 points of the modulation curve.
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 in the QRB sensor...
1. Check the wiring.
2. Flame detector probably faulty.
Check the wiring.
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.

Carry out a reset; if the error arises repeatedly, replace the unit.

control box.
Software version V03.10: If error C:99 D:3 occurs during the
standardisation of the VSD, temporarily deactivate the Alarm
function at the start of the pre-purging phase (parameter 210 =
0) or interrupt the signal controller-ON.
Carry out a reset; if the error arises repeatedly, replace the
control box.
