Excessive temperatures

Based on the ATEX Ex regulations, rotary drives must be protected against excessive temperatures with respect to the temperature class. This is done via an internal thermostat, which acts as a maximum threshold limiter and, if a fault occurs, will permanently turn off the rotary drive in the event of inadmissible temperatures. An upstream temperature sensor ensures the rotary drive is switched off before this point in the event of an operating error. This safety function is reversible, so the drive is operational again once it has cooled down. However, the fault must be remedied on-site immediately!
