1 Turn on the power supply of the double cone rotary vacuum dryer. At this time, the power indicator light should be on (6090 and 6210 should be turned on separately.) The temperature controller is energized and self-tested. The PV screen displays the measurement temperature in the working room. The SV screen displays The temperature set at the factory. The AT and HEAT lights on the temperature controller should be on, indicating that the instrument enters the warm working state.
2 Modify the set temperature 1) Press the function key (SET) of the temperature controller; after the SP screen displays the SP character, you can use the button to change the set temperature (6090 and 6210 to 2 and 3 instruments should be set separately) Fixed, the following categories).
2) After the modification is completed, press the SET button again, the PV screen displays the ST character and sets the timing time. If you do not use the timing function, still let its ST=0
3) Press the SET button again to make the PV screen display the studio temperature and the SV screen to display the new set temperature. The meter AT and HEAT lights are on, and the meter re-enters the warming state.
4) If the humidity of the double cone rotary vacuum dryer in the working chamber is large, the generated moisture will affect the performance of the vacuum pump. It is recommended to insert a “double cone rotary vacuum dryer†between the double cone rotary vacuum drying cabinet and the vacuum pump. /filter". The company can be equipped with a double-cone rotary vacuum drying machine with an external dimension of Φ120×300mm and an outer diameter of Φ16.
5) If inert gas such as nitrogen is required in the process of double-cone rotary vacuum dryer, it should be noted in the contract that an intake valve is added.
3 When the temperature in the working chamber is close to the set temperature, the HEAT light will be dimly lit and dark, indicating that the heating enters the PID adjustment stage. The meter sometimes measures the temperature exceeding the set temperature, and sometimes the temperature below the set temperature is normal. When the measured temperature is close to or equal to the set temperature, the studio enters a constant temperature state after 1~2h, and the item enters the double cone rotary vacuum dryer stage.
4 When the required temperature is low, the secondary setting mode can be used, such as the required working temperature of 70 ° C, * first set 60 ° C, the temperature overshoot starts to fall back, and then the second time set 70 ° C, so It can reduce or even eliminate the temperature overshoot phenomenon and enter the constant temperature state as soon as possible.
5 When the item double cone rotary vacuum dryer is finished, turn off the power supply. If the temperature is lowered, open the air release valve to make the vacuum level 0. Wait for about 5 minutes to open the door.
