Elevator fault **E41, follow the steps below to solve: Elevator E41 is a safety loop disconnection fault. Cause of failure:

The safety circuit fault should be regarded as one of the most common failures in the elevator. The judgment logic is very simple, and if the voltage is not detected at the detection point, the fault will be reported. There are two types of detection:

1. Low-voltage input point detection, the row of indicators on the left side of the motherboard, the input voltage is 24V, which is generally the normally closed feedback point of the detection contactor. 2. High-voltage input point detection, the position is at the bottom of the motherboard three high-voltage indicators, the input voltage is 110V, generally directly from the safety loop to separate a line, connected to the detection point. Solution:

1. The safety circuit mainly includes: phase sequence relay, control cabinet emergency stop, speed limiter switch, traction machine turning switch, (no machine room traction machine emergency stop), car top maintenance box emergency stop, (through the door and back door emergency stop), safety gear switch, (no machine room car stop switch), underground pit emergency stop, pit emergency stop, rope wheel switch, buffer switch, upper and lower limit nuclear switch. 2 This fault is very simple, if the safety circuit is not broken, still report this fault, then pay attention to two points 1) whether the insurance is burned, whether it is the power supply of the safety loop is out of power 2) an unused point, the wrong set of parameters, is defined as the detection point 3 Because the emergency electric operation of the control cabinet can shield a part of the safety loop switch, digging the foundation so there will be a control cabinet maintenance can take the elevator, but the car top is repaired to report the fault, and the fault is reported after returning to normal.

Pro-Elevator Fault**e41 means "Door motor overheating", this fault needs to be dealt with as follows:1Check whether the door motor and related motor control circuits have short circuit or grounding phenomenon, and if so, eliminate the short circuit fault first.

2.Check whether the working environment temperature of the door motor is too high, if the temperature of the machine room is too high, you can reduce the ambient temperature first. 3.

Check whether the setting parameters of the variable frequency drive of the door motor are correct, especially whether the acceleration and deceleration time and the upper torque limit are too large, resulting in the overheating of the door motor. It is necessary to adjust the inverter setting parameters to the appropriate range. 4.

Check whether the fan and heat sink of the door bend are stalled or have poor heat dissipation, and clean them first if necessary to keep the heat dissipation normal. 5.Disconnect the power supply of the door motor, and manually move the door panel to check whether it is flexible and normal.

If the movement of the door panel is not flexible, it means that there is a mechanical problem that causes the door motor to overheat and seep into the scene, and it needs to be repaired before the power can be turned on. 6.After confirming that there is no abnormality in the above problems, reset the elevator control system or power off for about 30 minutes before powering on, see whether the door motor continues to report the E41 overheating fault, if it continues to overheat the fault, it means that there is a problem with the door motor itself, and the door motor needs to be replaced before it can resume operation.

7.Restore the elevator power-on operation, observe the working condition of the door motor and temperature changes, and confirm that the fault has been completely solved. If it works normally, the elevator can be restored to normal use.

To sum up, to deal with the fault of E41 elevator, we should first eliminate external factors such as short circuit of relevant lines and excessive ambient temperature, and then check the internal causes of overheating caused by door motor control parameters and mechanical problems. Eventually, if the overheating fault cannot be resolved, the door motor will need to be replaced before it can fully resume operation. Continuous monitoring is required during the treatment process to confirm that the fault has been completely resolved.

Hello dear<>

<> elevator failure**E41 usually indicates that the elevator door lock is faulty, which can be caused by the following reasons:1The mechanical parts of the door lock are damaged or the mechanical block blocks the excavation.

2.The door lock circuit is incorrectly wired or the component is failing. 3.

The door lock control panel is faulty.

The processing method is as follows:1First, park the elevator on the nearest floor and make sure all passengers exit the elevator safely.

Set up warning signs near the computer room to prevent others from misoperation, and prohibit others from opening the elevator door. 2.Determine the cause of the failure:

Check whether the mechanical parts of the door lock are damaged or the mechanical blockage of Kainianzao, check whether the wiring of the door lock circuit is correct, and check whether the door lock control board is faulty. 3.If the door lock mechanical parts are damaged or the mechanical resistance is high, take the plug:

It is necessary to replace the corresponding mechanical parts or remove obstacles and clean the mechanical parts. 4.If the door lock circuit is miswired or the component fails:

It is necessary to check whether the door lock circuit is wired correctly and replace the damaged electrical components. 5.If the door lock control panel is faulty:

The door lock control panel needs to be replaced. 6.After the fault is resolved, the elevator is restarted and if everything is in order, it can be restored to normal use.

If the problem still exists, it needs to be further inspected or contacted by professional elevator maintenance personnel for treatment.

It is important to note that before performing any type of elevator repair, it is important to take proper safety measures and strictly follow the operating instructions.

E45: The up and down deceleration switch is disconnected.

Fault level : 4

Cause of failure: When stopping, the upper and lower 1-level deceleration switches are disconnected at the same time; Forced deceleration action, the elevator will also prompt e45 after deceleration, but it will automatically reset after 2 seconds.

Fault resolution.

1. Check that the contact between the upper and lower level deceleration switches is normal;

2. Confirm the characteristics of the upper and lower 1st deceleration signals (normally open, normally closed);

Tips for using elevators:

First, pay attention to the overrun overload elevator can not be overloaded, when the elevator alarm, you should take the initiative to exit, wait for the next trip and then ride, the elevator overload is very dangerous.

2. Do not block the elevator door, when the elevator door is about to close, do not force into the elevator, prevent the elevator from closing, and do not stay with one foot inside and one foot outside, which will be injured and ambushed.

Third, the round object does not press the emergency button casually, the emergency button is set up to deal with unexpected situations, the elevator is in normal operation, do not press the emergency button, otherwise it will bring you unnecessary trouble.

Fourth, when taking the elevator, if the elevator door is not closed and runs, it means that the elevator is faulty, passengers should not take it, and at the same time report the design to the maintenance personnel.

5. Before coming to the elevator, passengers first look to see if there is a "stop the elevator maintenance" sign. If the elevator is under maintenance, it should be hung with such a sign and passengers should not take it.

What to do if the elevator fails, we must maintain a calm state of mind, so as to do a good job of alarm measures, and the finch cavity also needs to do a good job of maintaining the balance of the body, so that you can protect your body, these related content everyone needs to pay attention to. What are the tips for using the elevator, these related common sense can be used in life, and you can get good help and solve some problems when you encounter them.
