E1保护:为系统高压保护。当连续3s检测到高压保护时,关闭除灯箱外的其他负载,屏蔽所有按键及遥控信号,指示灯闪烁并显示故障代码E1.。E2保护:为室内防冻结保护。在制冷、抽湿模式下,压缩机起动6min,连续3min检测到T蒸<-5℃时,指示灯闪烁并显示故障代码E2,停压缩机、外风机;当T蒸>6℃,且压缩机已停足3min时,指示灯灭,液晶恢复显示,原状态运行。不屏蔽按键。
E1 protection: High voltage protection for the system. When high voltage protection is detected for 3 seconds in a row, the load except the light box is turned off, all keys and remote control signals are shielded, and the indicator flashes and the fault code E1 is displayed. E2 protection: for indoor anti-freezing protection. In the mode of refrigeration and dehumidification, when the compressor starts for 6 minutes and detects T steaming <-5 degrees C for 3 minutes, the indicator flashes and displays the fault code E2, stops the compressor and the external fan; when T steaming > 6 degrees C and the compressor has stopped for 3 minutes, the indicator lights go out and the liquid crystal resumes to show the original state of operation. No shielding buttons.
E3保护:为系统低压保护。压缩机起动3min后开始检测低压开关信号,若连续3min检测到低压开关断开,则整机停,指示灯闪烁并显示故障代码E3,以提示漏氟。E4保护:为排气管高温保护。压缩机起动后,连续30s检测到排气温度高于120℃或排气感温头短路(或开路)时,指示灯闪烁并显示故障代码E4。
E3 protection: low voltage protection for the system. The low-voltage switch signal is detected after the compressor starts for 3 minutes. If the low-voltage switch is disconnected for 3 minutes, the whole machine will stop. The indicator flashes and the fault code E3 is displayed to indicate the leakage of fluorine. E4 protection: high temperature protection for exhaust pipe. After starting the compressor, the indicator flashes and the fault code E4 is displayed when the exhaust temperature is higher than 120 C or the short circuit (or open circuit) of the exhaust temperature sensor is detected for 30 seconds.
E5保护:为低电压保护。压缩机运转后,若连续3s检测到电流超过25A,指示灯闪烁并显示故障代码E5。EH保护:电加热故障。发出“BB”报警声,红灯闪。当环温>35℃时,强制进入制冷。故障原因如下:交流接触器内部粘连,须更换交流接触器。熔断器工作不正常,须更换熔断器。
E5 Protection: Low Voltage Protection. After the compressor is running, if the current exceeds 25A for 3 seconds, the indicator flashes and the fault code E5 is displayed. EH protection: electrical heating failure. Send out the "BB" alarm sound and the red light flashes. When the annular temperature is higher than 35 C, it is forced to enter the refrigeration. The reasons for the failure are as follows: AC contactor internal adhesion, AC contactor must be replaced. If the fuse is not working properly, the fuse must be replaced.
