Test function

The function of the auxiliary contacts can be verified by
means of an additional test button that has a dual function:
• Pressing the test button will open the break contact (NC)
95-96. The open contact will return to the closed position
as soon as the button is released.
This function can also be used to switch off the motor
manually.
• Pulling the button will trip the motor-protective relay. The
break contact 95-96 opens and the make contact 97-98
closes. After the test button is released, the motor-
protective relay must be reset in the same way as after a
normal tripping (a section "Reset"to page 37).
