Machine tool ventilation
A ventilation system must be switched on at the same time that the machine is switched on.
The E3IF500 measures the current draw of the machine and switches the external ventilation system on when the power draw exceeds 500 mA. At the same time, a maximum current of 16 A can be carried by the monitoring relay. This means that the switching on and off of the ventilation system cannot be forgotten.
– The high continuous current load saves additional current transformers
– Easier operation of the entire system with just one switch
– The user cannot forget to turn on the ventilation system
