¡¡¡¡Fireproof rolling shutter doors are one of the equipment that fire maintenance friends often need to test, and it is normal to encounter various malfunctions. Based on my over ten years of experience, I would like to summarize the following content for everyone.

¡¡¡¡1¡¢ What are the common faults encountered by rolling shutter doors

¡¡¡¡The malfunction indicator light of the rolling shutter door is on, indicating that the control motherboard has detected an abnormal situation. Nowadays, the functions of motherboards are constantly improving. In this situation, the following situations can be analyzed:
¡¡¡¡a£º¾íÁ±ÃÅÖ÷µçÔ´¹ÊÕÏ£¬ºÃ±È˵£¬È±Ï࣯´íÏ࣯Ƿѹ£¯¹ýѹ£¬¿ÉÒÔʹÓÃÍòÓñíÕÉÁ¿Ò»ÏµçÔ´Ðźż´¿É£»
¡¡¡¡a: The main power supply of the rolling shutter door is faulty, such as phase loss/wrong phase/undervoltage/overvoltage. You can use a multimeter to measure the power signal;
¡¡¡¡b£º±¸Óõç³Ø¹ÊÕÏ£¬³£¼ûµÄ¾ÍÊǵç³ØÎÞ·¨³äµçµ¼ÖÂǷѹ¡£
¡¡¡¡b: Backup battery failure is commonly caused by undervoltage due to the inability to charge the battery.

¡¡¡¡c: The power supply failure of the motherboard is due to the damage of the transformer inside the control box, which cannot provide normal power signals (usually the voltage is around 15V, which varies depending on the motherboard brand).
¡¡¡¡d£º¾íÁ±Ãżì²â²»µ½ÏÞλÐźš£ÔÚÖ÷°åÉÏ»áÓÐ2¸öLEDµÆ£¬ÏÔʾ¾íÁ±ÃÅ´¦ÓÚÉÏÏÞ»òÊÇÏÂÏÞ¡£
¡¡¡¡d: The rolling shutter door cannot detect the limit signal. There will be 2 LED lights on the motherboard, indicating whether the rolling shutter door is at the upper or lower limit.

¡¡¡¡When the fault indicator light comes on, you can refer to the above situations to troubleshoot one by one.

¡¡¡¡2. The remote control button of the rolling shutter door cannot lift the rolling shutter (it can only be lowered)

¡¡¡¡This situation is usually caused by the lack of a main power source, and the rolling shutter descends quickly (by its own weight). The function of the backup battery is to receive a signal from the remote control box (any button can be pressed) in the absence of a main power source, open the electromagnetic brake (like a car handbrake), and the roller blind will descend under its own gravity.
¡¡¡¡3¡¢Ô¶³Ì¿ØÖÆ°´Å¥ÎÞ·¨²Ù×÷¾íÁ±£¨×¢Òâ²î±ðÓÚÉϸöÎÊÌ⣩
¡¡¡¡3. The remote control button cannot operate the roller blind (note different from the previous issue)

¡¡¡¡The possible reason for this situation is that the button is damaged or the roller blind cannot detect the correct limit switch. You can judge it by the upper limit indicator light on the motherboard.

¡¡¡¡2¡¢ How do maintenance personnel replace the control board/controller of the rolling shutter door.

¡¡¡¡There are two aspects to pay attention to, one is whether the remote control button matches, and the other is the installation direction setting of the motor (left or right installation).
¡¡¡¡¸ü»»°ì·¨ÈçÏ£º
¡¡¡¡The replacement steps are as follows:
¡¡¡¡1¡¢½«¾íÁ±ÃÅϽµ°ëÃ××óÓÒ£¨¿ÉÒÔʹÓÃοØÊÍ·Å×°Ö㬻òÕßÀÁ´À´Ê¹¾íÁ±Ï½µ£©¡£
¡¡¡¡1. Lower the roller shutter door by about half a meter (you can use a temperature controlled release device or a zipper to lower the roller shutter).
¡¡¡¡2¡¢¸ü»»Íê³ÉÖ÷°å£¬Ë͵磬·¿ª¿ØÖÆÆ÷£¬µã¶¯¾íÁ±Ï½µµÄ°´Å¥£¬ÊÓ²ì¾íÁ±ÔËÐÐÆ«Ïò¡£Èô¾íÁ±Ï½µ£¬Ôò˵Ã÷µç»ú×°ÖÃÆ«ÏòÉèÖÃÕýÈ·£¬·´Ö®£¬Ôòµ÷½âÖ÷°åµÄ²¦Â뿪¹Ø¡££¨Ñ¡Ôñ×ó×°ÖûòÊÇÓÒ×°Öã©
¡¡¡¡2. Replace the motherboard, power on, turn on the controller, press the button to lower the roller shutter, and observe the direction of the roller shutter operation. If the roller blind descends, it indicates that the motor installation direction is set correctly. Otherwise, adjust the dip switch on the motherboard. (Choose left or right installation)

¡¡¡¡3. According to the debugging instructions of the motherboard, setting the roller shutter is either a one-step descent or a two-step descent (some roller shutters do not require this operation).
¡¡¡¡4¡¢Ô¶³Ì¿ØÖÆ°´Å¥µÄ¸ü»»¡£¾íÁ±µÄÔ¶³Ì¿ØÖÆ°´Å¥£¬Ä¿Ç°ÓÐÁ½ÖÖ£º¶àÏßÐÎʽºÍÄ£ÄâÁ¿ÐÎʽ¡£¶àÏßÐÎʽ£¬ºÜºÃÀí½â£¬¾ÍÊÇÏ߶࣬ÿ¸ö°´Å¥¶¼¶ÔÓ¦Ò»¸ùÏߣ¨Óй«¹²Ïߣ©¡£Ä£ÄâÁ¿ÐÎʽ£¬Í¨³£ÊÇ3¸ùÏß¡£×¢Ò⣬ÕâÁ½ÖÖ°´Å¥ÊDz»¿ÉÒÔÌæ»»£¬±ØÐëÓëÖ÷°å¶ÔÓ¦¡£
¡¡¡¡4. Replacement of remote control buttons. There are currently two types of remote control buttons for roller blinds: multi line form and analog form. Multi line form, easy to understand, means there are multiple lines, and each button corresponds to a line (with a common line). Analog form, usually consisting of 3 wires. Note that these two buttons cannot be replaced and must correspond to the motherboard.
