4.15 Calibration Of The Thermal Relay; Motor Rotation - Riello RS 310/M BLU Installation, Use And Maintenance Instructions

4.15 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.
The automatic reset can be dangerous. This oper-
ation is not foreseen in the burner operation.
Therefore do not position the "RESET" button
1) on "A".

the fan motor and check it is rotating anticlockwise (Fig. 11).
If this is not the case:

to carry out the switch-off phase.
Disconnect the electrical supply from the burner
by means of the main system switch.
DANGER
