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.

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.

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.
