Test function
An additional Test button enables the operation of the
auxiliary contact to be checked. The Test button has a dual
function here:
• When the button is pressed, the N/C contact 95-96 opens.
It falls back again when the button is released.
This function can also be used to switch off the motor
manually.
• Pulling the Test button will trip the overload relay. The
break contact 95-96 opens and the make contact 97-98
closes. After the test button is released, the overload relay
must be reset in the same way as after a normal tripping
