Introduction of alarm function of constant temperature and humidity Test Chamber

When the constant temperature and Humidity Chamber fails, a corresponding alarm will be issued. In what state will the device alarm? What should we do when it happens? What alarm functions does the constant temperature and Humidity Chamber have? There are many factors that can cause an alarm.

Anyone who has used a constant temperature and Humidity Chamber knows that it has an alarm function. When there is incorrect operation, it will automatically alarm and cut off the power automatically to stop working.

• When the temperature in the constant temperature and humidity room is too high, the induction system will alarm. At this time, the inside of the constant temperature and Humidity Chamber should be cooled immediately, but do not open the door immediately to avoid burns.

• When the fan in the constant temperature and Humidity Chamber is overheated or overcurrent, an alarm will occur.

(1) When the fan coil unit is overheated, the equipment will stop and alarm. Before proceeding with testing, we need to resolve the failure, otherwise, this is very dangerous.

(2) When the fan current exceeds the allowable value, the device will stop and give an alarm. After the overcurrent fault maintenance is completed, the device needs to resume normal operation.

• The refrigeration and heating compressors in the constant temperature and Humidity Chamber will also alarm when they are overheated. Due to long working hours, it may also be due to a malfunction in the cooling and heating system causing the compressor to heat up very quickly. At this time, we need to stop the test, check the compressor for problems, and repair it before putting it into service again.

• 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, when the set heating or humidification value is too high, it will also alarm.

• The power alarm of the constant temperature and humidity room. When the power plugs in the constant temperature and Humidity Chamber are 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 give an alarm. If we want to solve this problem, we need to find the problem quickly and deal with it.

• The compressor in the constant temperature and Humidity Chamber has an overpressure alarm. The refrigerant pressure of the compressor is set, but sometimes the device 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, and the constant temperature and Humidity Chamber can work normally. If reset fails, you can seek help from the chamber manufacturer

• Constant temperature and Humidity Chamber over-temperature alarm. The test samples are generally equipped with an over-temperature protection device, so when the constant temperature and Humidity Chamber is tested and the actual temperature in the working room exceeds the set temperature value, the constant temperature and Humidity Chamber will stop working and give an alarm. At this point we need to reset the temperature before the device starts working again.
