Have you ever encountered such a situation: When you use a large constant temperature and Humidity Chamber due to non-standard methods, the equipment will have various failures. When you encounter this situation, do you know how to solve it?
When the walk-in constant temperature and humidity room temperature humidity controller shows abnormal temperature
Checkout procedure:
(1) Please check if the over-temperature protector on the control panel is set to 150°C;
(2) Please check whether the circulating motor in the machine room is damaged or not running;
(3) Please check whether the solid-state relay of the temperature part is burnt out and short-circuited: If the heater is not burned out, please use the AC voltage range of the three-meter meter, and the voltage range is opened to 600 volts, and the red and black bars are marked on both sides, and the temperature part The temperature set point of the solid state relay is set to 0°CT. At this time, the indicator light in the temperature section of the solid state relay will not light up. If the measured voltage value does not change, keep it below 10V, it means that the solid state relay is burnt out and presents a short circuit.
solution:
(1) If not, please turn over the panel over-temperature protector to 150°C, or increase the use temperature by 30°C;
(2) Please notify the manufacturer's maintenance department to replace the circulation motor;
(3) Please replace the temperature part of the solid state relay (the solid state relay marked with T), or notify the manufacturer's maintenance department to come for maintenance.
When the walk-in constant temperature and humidity room temperature humidity controller has abnormal humidity
Checkout procedure:
(1) Please check whether the underwater over-temperature protector in the control room is set to 150°C;
(2) Please check whether the pipes in the computer room are too dirty, resulting in poor water flow;
(3) Please check whether there is water in the upper Water Tank, if there is no water, please check whether there is water in the lower Water Tank;
(4) Check whether the solid-state relay in the humidity section is burned out and short-circuited: If the heater is not burned out, please use the AC voltage range of the three-meter meter, and the voltage range is opened to the position of 600 volts, and the red and black bars are marked on both sides, and Set the humidity setting value of the humidity part to 0% AC side H. Solid state relay At this time, the indicator light of the solid state relay of the humidity part will not light up. If the measured voltage value does not change, keep it below 10V, and the solid state relay is burned out and presents a short circuit. Or set the humidity setting value to 0% first, and then check whether the water in the humidifying barrel in the computer room is boiling
solution:
(1) If not, please turn over the underwater over-temperature protector to 150°C;
（2）请关闭机器后部的主电源，然后将加湿桶下方的排水阀打开到与管道平行的位置。当水箱中的水全部排干时，使用扳手打开加湿桶并将其打开。由于长期潮湿，内部水垢被移除，然后将硅胶管取出，在水中擦洗，维护完成后，按照去除方法沿相反方向安装。安装完成后，加湿桶下方的排水阀需要关闭至管道路面处于垂直位置，然后打开机器后部的主电源;
（3）上下水箱内没有水，请给下水箱加水解决问题。如果上部水箱中没有水，而下部水箱中有水，则下部水箱的水泵电机就会损坏。请通知制造商的维修部门前来维修;
（4）请更换固态继电器的湿度部分（标有H的固态继电器），或通知厂家维修部门前来维修。
当步入式恒温恒湿室温湿度控制器出现压力异常时
结账程序：
（1）请检查设备的位置，是否与墙壁相距30厘米以上;
（2）请检查周围空间是否为密闭空间。
解决方案：
（1）如果没有，请在机器周围保持30厘米以上的位置，因为散热不良会导致压缩机高压侧压力过大;
（2）如果周围是密闭空间，会引起环境中的温度升高，也会对压缩机的高压侧造成压力过大，所以请保持周围通风。
当步入式恒温恒湿室温湿度控制器显示压缩机异常情况时
结账程序：
（1）请检查设备的位置，是否与墙壁相距30厘米以上;
（2）请检查周围是否为密闭空间。
解决方案：
（1）如果没有，请在机器周围保持30厘米以上的位置，因为散热不良会导致压缩机工作电流上升，从而导致过流保护器运行;
（2）如果周围是密闭空间，就会造成环境中的温度升高，也会导致压缩机工作电流上升，从而导致过流保护器（蓄热继电器）运行。所以请保持通风;
（3）上述问题解决后，请在机房的三个电磁开关下安装过电流保护器（蓄热继电器）。按下复位按钮，点击一下，表示受控压缩机过载，但此时也复位。此时，请将电流设置调至压缩机额定电流的1.25倍。
步入式恒温恒湿室温湿度控制器运行时，实际湿度值始终以100%显示。
结账程序：
（1）步入式恒温恒湿室中的空气非常干燥：一、检查干湿球架的水槽部分是否有水分;其次，请检查测试箱内的干湿球支架，是否挂在湿球传感器部分的湿球纱布是否在传感器部分上湿润;
(2) The air in the box is very humid (humidity may not reach 100%, but it is always high): first set the humidity part to 0%, and then check whether the humidifying barrel in the computer room is in a boiling state.
solution:
(1) If the air in the box is very dry: First, if there is no water, please adjust the water level cup in the machine room above, or check whether the pipe between the water level cup and the dry and wet ball fixing seat is blocked. After adjusting, soak up the water with a cloth to ensure that the water will continue to enter. Second, replace the gauze if it is not wet. (It is recommended to replace the gauze once a month. If you often use high temperature and high humidity conditions, the number of replacements will be more. If you only use temperature conditions, you can take out the gauze to prolong its service life. After taking it out, you can soak it in alcohol to prolong its service life .
(2) The air in the box is very humid (the humidity may not reach 100%, but it is always high): if it boils, please replace the solid state relay in the humidity part (the solid state relay marked with wire number H), or notify the manufacturer's maintenance department before Come for repairs.
