Sigi Schindler fault code

Sigi Schindler Elevator Co., Ltd. is a high-tech elevator manufacturer jointly invested by Swiss Schindler and Sigi. Is a professional large-scale enterprise engaged in elevator R&D, manufacturing, sales, installation and maintenance services. We can provide users with various elevator products and services such as passenger elevators, medical elevators, sightseeing elevators, escalators, sidewalks, freight elevators, car elevators, hydraulic elevators, villa elevators, meal ladder and so on. The following is the fault code of Xiji Schindler elevator compiled by Elevator Recruitment Network. Welcome to learn!

Fault Analysis of Xiji Xunda Escalator

Method for proces coding error content

ER02 safety circuit error 1, safety circuit disconnected.

Phenomenon 1: A switch of the safety circuit is open. Please check the switch of the safety circuit.

Phenomenon 2: Top flush or pier bottom.

(1) If the floor between the top floor or the bottom floor is too high, and the installation distance between the upper and lower stations is too small, the elevator will run in the wrong number due to power failure in operation. After encountering forced speed change, the insufficient speed change distance will lead to the elevator running offside and rushing to the top floor or pier bottom (multi-stage occurrence). When the stair speed is less than 2m (excluding 2m), if the building spacing between the top floor and the bottom floor is sufficient, the installation position of the terminal station should be close to the variable speed distance (0. 1m) of the maximum running curve at a given time. When the space between the top and bottom buildings is insufficient, the installation position is 1.75 seconds, which is more than 2.5 meters and less than the space between the top and bottom buildings. Note that the installation of the lower station must be lower than the door area on the second floor. The upper station must be higher than the door area of the second top floor.

② The installation position of the terminal station is too small, and it reaches the top door area or the bottom door area during operation. One of the two sensors in the door area passes through the door area and there is no signal, resulting in multi-stage timing and delayed transmission of variable speed signals. However, after the installation position of the terminal station, the terminal station cannot change the running curve and cause offside. Adjust the depth of the door panel inserted into the sensor, so that the door sensor can work reliably.

(3) The wrong position of the upper and lower stations causes the shift position of the low-speed curve to be delayed, resulting in the elevator offside rushing to the upper and lower limits. Due to the long-term influence, the upper and lower stations have higher installation positions, and their action positions are later than the original self-learning positions. When the control system meets the terminal station, the corrected scale deviates from the self-learning position, which makes the low-speed curve or speed change point late and causes the elevator to run over the position. Please readjust the switch of the terminal station and conduct self-learning to make the terminal station operate reliably.

(4) The terminal station is out of order, and the terminal station switch is in a high position due to long-term impact, so it cannot operate normally. The elevator is prone to roof fall and pier bottom after staggered floor operation for other reasons. Please check the installation of the terminal station.

⑤ For example, when the direction of 02 fault 1 in the fault record is downward, it is because the system gives the downward running direction, and the inverter can't output torque normally after opening the door, resulting in the elevator sliding upward and rushing to the top. This phenomenon will occur if the inverter outputs are out of phase. Check the reason of missing phase.

⑥ When the running direction is enabled by the control system or the door is opened and closed, the 24V power supply is unstable, and the terminal station or the limit signal is misoperated to cause the wrong number, which runs in the opposite direction at the top or bottom, and stops and blocks when it reaches the limit. Please increase the capacity of the switching power supply to prevent the 24V power supply from being unstable.

2, safety failure, safety contactor contact state is inconsistent with the coil state:

Phenomenon 1: The input type entered is incorrect.

Phenomenon 2: The coil state input of the high-voltage port is damaged and the coil voltage is too high.

Phenomenon 3: The coil voltage is too low (less than AC 100V).

Phenomenon 4: The input capacitor of the motherboard is damaged, because the coil is not equipped with an arc extinguisher.

ER03 KMC state mismatch error

ER04 KMY state mismatch error phenomenon 1: After the control system outputs the operating contactor instruction, the operating contactor cannot be closed. Check whether the wiring is correct and whether the contactor is damaged.
