】 【Weak current College (go) Elevator equipment failure of alternative disposal methods.

After many years on some of the elevator industry, I think it's normal elevator maintenance workers (master) are similar to traditional craftsman-maintenance method, although the elevator malfunction can handle, but generally there is a 1%-5% of the elevator malfunction cannot (or not clever) solution, I think this elevator users and elevator maintenance units have a definite loss, I have worked on some seem special elevator malfunction, use the "alternative" ways basically solved, is an example to illustrate, if you can make the colleagues in dealing with the same failure to draw out the role of nature is my greatest pleasure, if there are errors between the urge to testify against peer generalists criticism.

(1) does not change the basic computer Board can also repair computer easy panic's fault

I believe each elevator maintenance workers have experienced elevator computer crash and not running, check to find out that it is difficult to determine the real reason, but as long as the lift power off after re-power transmission, the elevator was functioning properly, but a few days we have seen that bother you? this is Yes, if you are a little electronic technology based maintenance work, in fact, you can easily panic lift retrofit a simple device that can automatically handle such failures, such as the Elevator Express run signal plus outside call signal or sedan handling and signals in the context of the analysis, when the fruit has a panic situation arises, the device will start the lift power down once and close, such failure naturally no longer appear (or barely can cross the). Believe that wise you must know how to do it, do not know it, and I contact us to discuss.

(2) series a diode, saved a door plate

One elevator use several years normal, reached in 2002 began to fail, expressed as the number of hours run by the elevator door motor does not work, fault display code for the door plate overheat protection, the elevator stops running for about half an hour later and then power on the elevator was functioning, particularly in the summer the temperature is high day may appear several times, after changing the new crane plates. troubleshooting after careful analysis, may be a computer chip parameters changed, resulting in overheating protection, such as door plate chip voltage appropriate to reduce, should be able to reduce chip temperature rise, so in the regulated power supply series after a trial run of elevator normal diode, one year, without fail, believe it or not-write here, I also recall a few solutions, such as the Office computer CPU used by fans to fixed in labile chip, and then pass the appropriate voltage for the cooling, should also be addressed. If you cannot use the elevator room fitted with air conditioning, the effect is more pronounced.

(3) are sound to blame

A factory in Shenzhen longhua has a Shanghai Mitsubishi SG-VF (A) the type of frequency adjustment, normally using the normal freight elevator, from the third floor offers employees a recreation room often fails after the elevator, the Office often has a stereo music, as long as the audio is set, the lift will not be able to close the door, repair work after few months long overhaul are unable to resolve the issue that had to require users to stop using audio. subsequently learned of this after I, to the user after consultation with the user will check the user sound apart, did not find fault, only know that the sound is interference source, so they are metal-Park (central air-conditioning ducts) posts in audio enclosures and Earth (non-Earth yo) after commissioning, audio work completely normal, lift switch can also be freely, dear friends, is a bit too believe.
(4) do not need any interface can also be retrofitted to station clock

I work for an elevator company in Shenzhen, has sold a Shanghai Mitsubishi elevator to HOPE-Shenzhen Public Security Bureau, taking into account their training schools need a quiet environment, at that time did not configure the elevator car to the station clock, Elevator installed the user charge requires the installation of the clock, the captain requested user elevator installation plus RMB 5000 Yuan will agree to complete the installation of the lift, the user also agrees, but after one year still cannot hear elevator Bell, issued to the station because the elevator did not stop the clock interface, buy to station clock does not work, even if there is an interface, but also to reprogramming, I'm afraid is $ 5000, the captain can't have visited several elevator repair expert, but asking price in RMB 12000 generalists and above, an excuse work also reluctant to come forward, it appears that had to be dropped, the captain was informed that I can address some of the electronics and electrical engineering with special problems, with a grain of salt and asked me to handle and clear requirements for the elevator is not required in a few seconds before the Bell, issued also calls the elevator maintenance when running (local train) stop shall not make a sound, and I agree to the price of the RMB 1500 Yuan Gao Ding. my home design three programmes, the last selected a programme for the Assembly, and sure enough to meet user requirements and the captain of the team, so I set this to the Bell named "universal elevator car to stop the clock", the most major characteristic is: can any brand of elevator use, without any interfaces, no need to install any software that is simple, with the exception you can work as interested, to Shenzhen, Zhenhua Group Office building to look at, the elevator is equipped with a Bell.

(5) no computer Board, can go climbing

A few years ago to the day of an elevator installation site to find friends, see installation teams Schindler licensing is installed 3 tons of freight elevator, model, remember that only know is two-speed hoist, lift master guides, car, etc. have been installed, the chef who are debugging lock, and other related facilities, but due to the lift computer Board hasn't arrived (Note: required to wait until the manufacturers represented only bring together when debugging), Elevator, of course, cannot go climbing, to master who brought considerable inconvenience. I therefore to the elevator room watching a while, found that the elevator is a two-speed host motor motor (Note: I'm his first official contact with elevator), so I watch carefully the structure of the elevator, I think that as long as both the lift motor slow winding and electromagnetic brakeAdd the appropriate voltage, the lift must be running slow, I'll use the elevator of the contactor received into reverse control circuit, electromagnetic brake on the 110 volt DC take control cabinet in out-of-the-box, but also through a contactor control, after several lines after the elevator was able to run slow, to adjust layer door, etc. brought exceptional convenience, if you are encountering the same problem, may wish to try it, really quite convenient.

(6) cannot be delivered for erection of wires, the lift alarm signals

Shenzhen Bao'an elevator company maintenance of elevators, school a school called lift alarm signal to the control center of the signal, as the room and elevator machine room are about 350 meters above the sea level, the school also requires no erection difficulty passing by, construction is quite high, the elevator company there is no good way to contact me, finally, I will use wireless handsets are converted, not only can reliably in the elevator car alarm signal sent to the Office, but also from Wired control elevator to return to the first floor (return fire), fully achieved two birds with one stone, interested friends can try.
