Controller set value adjustment steps are illustrated as follows:
【Example】: Select -15 ~ 15 ℃ specifications of the temperature controller, the requirement to control a cold storage temperature is maintained in the range of -8 ~ -5 ℃.
Specific operation steps are as follows.
- temperature package fixed in the warehouse, the controller is installed outside the warehouse instrument panel, capillary tube should be fixed section by section, with wires to connect the controller into the power control circuit of the freezer motor;
- rotate the set value adjustment lever, make the pointer indicates on the scale scale -8 ℃. This value is the lowerswitching value;
- when the temperature drops to -8 ℃, the controller switch should automatically switch the chiller, when the chiller stop the temperature back up, repeatedly adjust the switch difference Knob, makethe temperature of the library back up to the switching value of -5 ℃, the controller switch switch, until the freezer start again.
- Open the meter cover and install the controller vertically on the meter, it is strictly forbidden to pluck the arm by hand or collide with tools to prevent changing the performance:
- remove the lock nut, rotate the adjusting lever, make the pointer point to the desired control temperature setting value, tighten the lock nut;
- rotate the switching difference knob to obtain the required switching difference;
- temperature package capillary: temperature package should be fully immersed in the controlled medium, the surrounding medium should be kept flowing evenly temperature,Capillary tube bending arc radius of not less than 50mm, every 300mm should be fixed to the capillary tube card on the instrument panel.No.1-4 capillary tube through the ambient temperature should be higher than the set temperature 3 ℃;No.6-7 ambient temperature should be lower than the set temperature of less than 3 ℃;No.9-10 ambient temperature should be higher than 5 ℃, installation and use to prevent mechanical collision and the pressure transfer capillary tube flattening;
- check whether the installation is correct, install the meter cover and turn on the power. The controller should be calibrated periodically according to the use of the controller.
Note
- the controller pointer indication value is the set value, is the lower switching value, the set value adjustment range is the lower switching value adjustment range;
- The number on the switch difference knob only indicates the switch value and not the actual value, the actual value should be read from the standard table.
- to control the temperature does not exceed a given pressure value ( the upper switching value), the pointer should be adjusted at a position one switching difference (lower switching value) lower than this given value, and after the adjustment is completed, after adjustment, do not turn the switch difference knob again;
- the switching difference adjustment range given in the specification table is the minimum adjustment range guaranteed, the actual range can be slightly wider than the value listed in the table.
