4.11.1 Calibration of the thermal relay
The thermal relay (Fig. 23) 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 no.
7 in Appendix A.
If the minimum value of the scale of the thermal relay is greater
than the rating absorption of the motor, protection is still en-
sured. 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 “
RESET
” (Fig. 23).
The button “
STOP
” (Fig. 23) opens the NC (95-96) contact and
stops the motor.
To test the thermal relay, insert a screwdriver in the window
“
TEST
” (Fig. 24) 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.
