Temperature controll, . temperature limitation and flow monitoring need . to be implemented propperly. . 2) The thermocouples are for temperature limi- . tation purpose. They need to get connected . through intrinsic safe circuits (Ex ic) to . electronic safety temperature limites (ESTBs) . inside of the electronic control unit. . The trip points of this ESTBs need to be adjusted . to a maximum temperature of 300°C and locked. . The control unit needs to initiate an automatic . power shutdown in case of ESTB tripped. . 3) The equippment is marked as T. to indicate that . additional measures are necessary in order to . certify for a temperatur class. In this case, the . temperature limitation need to get implemented . propperly by the electric control unit and a . thermal piece test needs to get performed . under operation conditions. . 4) Thermal piece test is not included in the . price. We can offer it separately if reed.
