Temperature monitoring
The temperature of the heat sink is constantly monitored via a temperaure sensor. This sensor is a temperature
dependent resistor (NTC = negative temperature coe󰀩cient). The higher the temperature, the lower the resistance
value of the sensor.

DSP
DK-MAPRO
The DSP is monitoring the temperature of the heatsink and as soon as the temperature reaches the programmed
maximum value, the machine will stop and displays E01 (thermal overload).
The actual value of the temperature can be displayed at the front panel in menu Extras, Diagnosis, Module Tem-
peratures.
If one of the temperature sensors are faulty itself, then the machine will stop and E13 (Temp.sensor error) is dis-
played.
