Calibration Of The Thermal Relay - Riello RS 160/E BLU Installation, Use And Maintenance Instructions

5.13

Calibration of the thermal relay

The thermal relay is used to avoid damage to the motor owing to
a strong increase in absorption or the lack of a phase. For the
calibration 2)(Fig. 29), refer to the table given in electrical layout.
If the minimum value of the scale of the thermal relay is greater
than the rating absorption of the motor, protection is still ensured.
To reset, in the case of an intervention of the thermal relay, press
the button " RESET " 1).
The button " STOP " 3) opens the NC (95-96) contact and stops
the motor.
To test the thermal relay, insert a screwdriver in the window
" TEST/TRIP " 4) and move it in the sense of the arrow (towards
right).
Automatic resetting can be dangerous.
This action is not provided for the burner opera-
tion.
