Thermal relay calibration of the fan motor
The thermal relay (Fig. 40) 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), refer to the table given in electrical layout
(Electrical connections set by installer).
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 op-
eration.
WARNING
5.17
Thermal relay calibration of the pump motor
The thermal relay (Fig. 41) is used to avoid damage to the motor
owing to a strong increase in absorption or the lack of a phase.
For the calibration, 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.
This arises when the power supply of the motor is 400V.
To reset, in the case of an intervention of the thermal relay, press
the button 1)(Fig. 41).
