How to short circuit the safety loop of Deao elevator

Deao elevator incident. The newly installed elevator is used for half a year, frequent failures, during the recent decoration of the materials by the owner, the elevator box is misplaced, the maintenance and sales representative replied that the elevator load is 1600 kg, and now the load is 800 kg, because the owner of the material is unbalanced, the angle of the door is wrong, resulting in the displacement of the box, the manufacturer does not provide maintenance. It is necessary to pay for the maintenance of the material owner or the elevator purchaser.

Contact Mr. Zhu of Xi'an Office, reply to things, he knows, through who bought the elevator to find whom, this is the answer of the senior leaders of Deao to an owner consumer, try to ask Deao manufacturers? The owner does not deliberately damage the elevator, there is no more than half of the elevator load, the box displacement occurs, whose fault is it, whose fault is it, whose responsibility is it, and who pays for it? Less than half of the load capacity leads to the displacement of the elevator box, is such a product qualified?

Does the owner dare to use it? Will the results of such a treatment chill the majority of owners?

2x01--2x31 overspeed switch, 2x31--1x26 rope sliding switch, upper and lower limit.

1x26--1x28 safety window, safety gear, belt break switch, 1x28--1x29 car roof emergency stop.

1x29--1x13 car door contact.

2x34--2x35 hall door contact.

2x35--2x36 counterweight, car buffer, pit emergency stop.

According to the requirements of Otis safety operation specifications, the safety loop is short of the signal leakage section, and it is not allowed to short-circuit a wire search field from the beginning to the end, if you need to do the safety gear test, you only need to short-circuit 2x01--2x31 overspeed switch and 1x26--1x28 car safety switch circuit, other safety switches are not short-circuited, so that it still plays a protective role.

Related information: The elevator safety circuit is short-circuited and sealed, which is mainly used temporarily when judging what the elevator is faulty. Remember to short circuit (seal the wire) to determine the fault and be sure to remove it after returning to normal!!

For example, the elevator cannot operate normally, and the safety circuit is faulty after investigation. Because the safety circuit is connected in series with the machine room (speed limiter switch, rope clamp switch, machine room emergency stop switch, etc.), car (safety gear switch, safety window switch, car top emergency stop switch, etc.), hoistway and pit (buffer switch, speed limiter tensioner switch, pit emergency stop switch, etc.), if it is not good to check and judge one by one, the elevator can be converted into a maintenance state in the machine room for the convenience of judgment, and the safety loop of the machine room and the car safety loop are gradually shorted according to the drawings on the control panel. The safety circuit of the shaft pit (such as the short-circuit car safety circuit elevator overhaul the moving car, then it can be determined that there is a problem with the car safety switch, which can shorten the maintenance time.

Summary. The elevator safety loop is short-circuited and sealed, which is mainly used temporarily when judging what the elevator is faulty. Remember to short-circuit (sealing) to determine the fault and return to normal must be removed, the safety loop, that is, in the elevator safety components are equipped with a safety switch, all the safety switches in series, control a safety relay.

Only when all safety switches are turned on and the safety relay is engaged, can the elevator be energized.

Hello, in order to avoid any possible accidents, it is not recommended to carry out any unauthorized repair operations on the Otis escalator. If you notice a short circuit in the safety circuit of your Otis escalator, you should stop using the escalator immediately and contact a professional maintenance personnel for repairs. If you need urgent treatment, here are some things you can try:

1.Immediately stop using the escalator to ensure the safety of passengers. 2.

Turn off the power supply to make sure the escalator is no longer running. 3.Jianxiang Town slowly checks whether the safety circuit cable is damaged, poor contact or short circuit.

If there is a problem, the cable should be replaced or repaired. 4.Plug it back in and test if the safe return to the travel outlet is back to normal.

It should be noted that the Otis escalator is a very complex mechanical device, and the maintenance operation requires professional skills and experience. In order to ensure the safe and stable operation of the escalator, it is recommended that you do not carry out any unauthorized maintenance operations, but contact professional maintenance personnel for processing.

I'm really sorry to keep you waiting. In order to avoid accidents caused by misoperation or malfunction of Otis escalators, the safety circuit is very important. If you need to short the safety loop of an Otis escalator, follow these steps:

1.Start by determining the location of the safety loop. Usually the safety loop is located on the controller center board.

2.Open the controller box door and locate the safety loop interface. 3.

Connect the two adjacent terminals on the safety loop interface with a single conductor. This is equivalent to shorting the safety loop. 4.

After confirming that the short circuit is successful, close the door of the control beam and restart the Otis escalator. It is important to note that shorting the safety loop may cause the Otis escalator to lose its protective function, so personnel should avoid using the Otis escalator until the fault is confirmed to have been fixed. At the same time, for any work involving the operation of electrical equipment, it is recommended that you seek the guidance and assistance of professional technicians to ensure that the operation is safe and correct.
