PE (Protective Earth) -Protection

The PE monitoring is a standard feature in every machine. As soon as a current >15A is

flowing via the PE wire of the mains cable, a reed-contact opens up and the machine stops with

Cooling unit

Since January 14th 2016 the water cooled machines of the MicorMIG series are equiped with a water monitoring.

A sensor is mounted in the water tank, that is washed around by the cooling water of the return-flow. The sensor

is a “self-heating” sensor: the temperature is decreasing as soon as the water is flowing over it. If the water is not

flowing, the temperature of the sensor is kept stable.

If the pump is running and a flow of the water cannot be detected for longer than seven seconds, the machine

stops with the error message

7 seconds to 10 seconds.
