Warning

All interventions (assembly and installation operations,
assistance, etc.) must be carried out by qualified personnel.

Before modifying the wiring of the servomotor in the connec-
tion area, fully disconnect the burner control device from the
power supply (omnipolar separation).

To avoid the risk of electrocution, protect the connection ter-
minals in a suitable manner and correctly fix the cover.

After every intervention (assembly and installation opera-
tions, assistance, etc.), ensure the wiring is in order, then
make the safety checks.

Falls and collisions can negatively affect the safety func-
tions. In this case, the servomotor must not be operated,
even if it displays no evident damage.
Installation notes

The static torque is reduced when the electrical supply of the
actuator is switched off.

4.16 Calibration of the thermal relay
The thermal relay serves to avoid damage to the motor due to an
excessive absorption increase or if a phase is missing.
For calibration 2), see the table in the wiring diagram.
To reset, in case of an intervention of the thermal relay, press the
"RESET" button 1) of Fig. 10. The red “TEST” button 3) opens the
NC (95-96) contact and stops the motor.

damage, observe the following instructions!
Do not open, modify or force the actuators.

WARNING WARNING
During the maintenance or replacement of the
actuators, be careful not to invert the connec-
tors.
WARNING WARNING
Condensation, the formation of ice and the entry
of water are prohibited!
