Nov 28, 2018

One. Q: Why does the main control board always display 888 after power-on?


A: After the power is turned on, the main control board always displays 888 because the program initialization is unsuccessful.


1. Power off, re-power on after the discharge is complete;


2. Check if the main control board J9 J10 has jumpers at the same time;


two. Q: Why is the display still not displayed after the external board is connected?


A: It is caused by a mistake in the communication. Check parameters F5-33, F5-33 bit0=1;

A: The signal in the door area is abnormal.


1. Check if the door zone signal is valid when the elevator is in the non-door zone;


2. If the door zone signal sensor is not used, has the door zone detection been set; if it is set, please cancel it.

Fives. Q: Why does the automatic rescue drive open without opening the floor?


A: Because the door area signal is wrong.


1. Check if the door zone signal is valid when the elevator is in the non-door zone;


2. If the door zone signal sensor is not used, has the door zone detection been set; if it is set, cancel it and set F5-02=00.

1. Before the operation, the thermal protection switch is disconnected and reported to E36 fault to check whether it is a thermal protection action;


2. The contact point of the running contactor before operation should be kept closed; during operation, the contactor of the running contactor is disconnected and the X6 point is valid.

2. Check that the FE-33=34 door open signal is valid, but the door open signal will still be output.


A, there is a problem with the door opening wiring.


B, test set FE-33=32 to see if the door can be opened normally. If there is a problem with the door wiring, or if there is a problem with the F5-25 setting.


C, Supplementary note: Since FE-33=34 is set, the door is opened in place. If there is a problem with setting F5-25 to open the door, open the door as usual.


D, E53 is reported when the elevator starts, indicating that the door open wiring and F5-25 menu settings are inconsistent. It is considered that the detected limit is valid and the door lock is open (think shorted).


Thirty-six. Ask why the E17 is faulty or has a flying phenomenon when it is powered on.


Answer: The elevator can run normally, but it will report E17 fault when it is powered on again after power off.


The reason is that the encoder does not pass the check after power-on.


After power-on, the system reads the encoder angle data (that is, the FA-03 data stored at power-off) from F1-07, and reads the angle data of the current encoder through the voltage conditions of C and D; if the two are different If it is not large, use the data of F1-07. If the difference is more than 30 degrees, the system selects the angle judged by the CD voltage. If the calibration process is disturbed or the cable is faulty, the system reports E17 and the speed of the car. The internal encoder angle is too far from the actual angle.
