When the constant temperature and humidity chamber fails, a corresponding alarm will be issued. In what state will the device alarm? What do we do when it occurs? What alarm functions does the constant temperature and humidity chamber have? There are many factors that can cause an alarm.
People who have used the constant temperature and humidity chamber know that it has an alarm function. When there is an incorrect operation, it will automatically alarm and automatically cut off the power to stop working.
1. When the temperature in the constant temperature and humidity chamber is too high, the induction system will alarm. At this time, we should immediately cool the inside of the constant temperature and humidity chamber, but do not open the door immediately to avoid burns.
2. When the fan of the constant temperature and humidity chamber is overheated or overcurrent, an alarm will occur.
(1) When the fan coil is overheated, the equipment stops and alarms. We must solve the fault before continuing the test, otherwise, it is very dangerous.
(2) When the fan current exceeds the allowable value, the equipment will stop and alarm, and the equipment must be restored to normal operation after the overcurrent fault maintenance is completed.
3. The refrigeration and heating compressors of the constant temperature and humidity chamber will also alarm when overheated. Due to the long working hours, it may also be due to the failure of the refrigeration and heating systems that cause the compressor to heat up very quickly. At this time, we must stop the test, check the problem with the compressor, and repair it before it can be put into use again.
4. The alarm system of the constant temperature and humidity test chamber will also remind the operator of improper operation. When the operator operates the constant temperature and humidity chamber, it will also alarm when the set heating or humidification value is too high.
5. The power alarm of the constant temperature and humidity chamber. When the power plug of the constant temperature and humidity chamber is out of phase or there are too many wires and the order is messy, the constant temperature and humidity chamber will automatically stop running and alarm. If we want to solve this problem, we need to quickly find the problem and deal with it.
6. The compressor of the constant temperature and humidity chamber has an overpressure alarm. The refrigerant pressure of the compressor is set, but sometimes the equipment will cause the pressure to exceed the set value due to too much or too little refrigerant, and an alarm will appear. We just need to reset it manually, the constant temperature and humidity chamber can work normally. If the reset fails, you can ask the environmental chamber manufacturer for help
7. The over-temperature alarm of constant temperature and humidity chamber. The test sample is generally equipped with an over-temperature protection device, so when the constant temperature and humidity chamber is being tested, and the actual temperature in the work room exceeds the set temperature value, the constant temperature and humidity chamber will stop working and alarm. At this time, we need to reset the temperature before the device start to work again.
