2. TEMPERATURE CONTROLLER KIA USER MANUAL User Manual for DESMI ROTAN KIA temperature controller Function of the temperature control box The temperature control box shall secure the motor which drives the pump not to start until the temperature in the pump has reached the adjusted level This level has to be adjusted to a tempera ture where the liquid In the pump 15 liguified enough to be pumped without damaging the pump The control box turns on and shuts off the connected cartridee heaters and sends a start sienal to the motor control The motor will be released 5 degrees before the adjusted level 1s attained Ex If the temperature level on the control box is adjusted to 155 C a start signal will be sent to the motor control when the temperature level is measured to 150 C This signal will maintain until the temperature 1s too low When the temperature 1s at 155 C the cartridge heaters will be shut off If the temperature decrease to 4 C lower than the adjusted level the cartridge heaters automatically will be turned on again Display key buttons and lamps on KIA temperature controller Key button functions F This key button Is only used in the special operator menu It is not used by the ordi nary user v This key button Is used for decreasing changing the temperature value set point Press the key button until the wanted value 1s shown in the display A This key button Is used for increasing changing th

4. l Cartridge heaters The voltage for the electrical heaters used in electrically heated ROTAN pumps are 230V Wattage see separate scheme If the pump is equipped with more than one cartridge heater the cables from the cartridge heaters can be joined together in a junction box and a single cable from there can be connected to the operating device for instance a temperature control box Heating time The heating time for HD and GP pumps equipped with electrical cartridge heaters from 20 C to 150 is about four hours This is when the pump is insulated When the pump is not insulated the heating time will extend about 50 or more The heating time will vary depending on the ambient temperature and air It is highly recommended to insulate the front cover the pump casing and the rear cover against the pump casing with 50 mm windtight insulation The bearing bracket item CQ may not be insulated because this will cause the ball bearing item CU to be too warm Stuffing Box The stuffing box packings with Desmi Rotan material code 825 used in ROTAN pumps for Asphalt and Bitumen is made of discontinuous aramidic yarns with a graphite based compound impregnation The temperature range is between 100 to 400 2 For rotating pumps the pressure rating is up to 50 bar and the speed limit is 15 m s The chemical resistance is pH 2 12 Mechanical shaftseal When the pump is equipped with a mechanical shaft seal the temperature sensor has
