Thermal shock test chamber controller display failure

TEMAK thermal shock test chamber is divided into two-box and three-box type, the difference lies in the test mode and the internal structure is different. However, in the use of thermal shock test chamber may encounter equipment failure, the following list of several kinds of thermal shock test chamber controller common several display failure tips for your reference. 

Controller common display faults and solutions:

I. Thermal shock test chamber over-temperature alarm: the controller prompts abnormal temperature

1. Check whether the temperature set by the over-temperature protector is at 150 ℃. If not, adjust the over-temperature protector to the position of 150 ℃, or use the temperature and then add 30 ℃ position; 

2. Check whether the circulating motor of the thermal shock test chamber is malfunctioning causing it not to work. If the motor is damaged, contact the equipment manufacturer's customer service maintenance department to replace the circulation motor; 

3. Check whether the solid state relay controlling the temperature section is short-circuited. If it is short-circuited, replace the temperature part of the solid state relay (line number labeled T that a solid state relay), or notify the after-sales service to repair.

II. The water level is abnormal: the controller displays a water shortage alarm

1. Check whether the water level line of the storage tank in the lower right corner is lower than the low water level line; if the water level is too low, open the water cover and add enough pure water; 

2. Check whether the float water level switch in the storage tank is invalid; if the switch is invalid, then toggle the float switch to restore its working ability. 

III. The temperature and humidity controller shows abnormal humidity

1. First test the control of the over-temperature protector of the heater, whether it is set at 150 ℃ position, if not, it should be set at 150 ℃; 

2. Check whether the pipeline of the circulating water circuit is too dirty, resulting in poor water flow, if the water circuit is impassable, the pipeline should be cleaned up in time; 

3. Check whether there is water in the water tank, if there is no water, then add pure water in time; 

4. Check whether the humidity part of the solid state relay burned short circuit, if a short circuit occurs, the relay must be replaced immediately. 

TEMAK three-box thermal shock test chamber, for example, the technical parameters are shown below: 

TEMAK thermal shock test chamber advantages:

1. the shell is made of cold-rolled thin steel plate, the surface of plastic spray treatment, beautiful and durable. 

2. the controller is simple to operate, using PID automatic algorithm control, high precision temperature control; 

3. It can complete the temperature change rate of not more than 3℃/min to raise and lower the air temperature inside the box to room temperature; 

4. The air outlet and return air outlet sensor detection and control, air door mechanism switching time for 10 seconds to complete, cold and heat shock temperature recovery time of 5 minutes to complete; 

5. Advanced scientific air circulation circulation design, so that the indoor temperature uniformity, to avoid any dead ends; 

6. With full-automatic, high-precision system circuit, any machine action, with PLC lock processing; 

7. TEMAK thermal shock test chamber`s refrigeration and air circulation system use the world's leading technology BITZER compressor. 

8. The structure of the combined design ideas, with a simple appearance, the ideal way of assembly, compact box structure, maintenance is very easy to use; 

9. Equipped with temperature control sensor and over-temperature protection function, the device is perfect and reliable, to ensure the safety of the sample and the test temperature is stable and controllable.
