One of the common problems with the Monarch system

1、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;
3. Contact Modern Fuji.

2、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

3、Q: Why does the external signboard only display the floor without the maintenance sign and direction arrow?

A: It is caused by a mistake in the communication.

1. Check parameters F5-33, F5-33 bit0=1;
2. Check parameters F5-33, F5-33 bit3=0;

4、Q: Why does the elevator switch to normal and the elevator does not return to the leveling floor to open the door immediately?

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. Set F5-02=00.

5、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. Whether the door zone detection has been set when the door zone signal sensor is not used; if set, please cancel, set F5-02=00

6、Q: Why does the fire door not open after returning to the base?

A: The door open signal is wrong.

The F5-35 monitors whether the door open signal works normally, and 1:C lights up after the door is opened.

1. If the signal is not normal, please check the door open parameter setting F5-25. (Except for the TD3200 door controller, when using other models of door controllers, the F5-25 should be set to 64).
2. Whether the door is in place or not has been connected to the door.
3. Whether the door opener can output the door open signal when the door is opened. (The signal can be monitored by the door controller or measured using a tool)

7、 Q: Why does the elevator run on every floor without any instructions?

A: The door open signal is wrong.

The F5-35 monitors whether the door open signal works normally, and 1:C lights up after the door is opened.

1. If the signal is not normal, please check the door open parameter setting F5-25. (Except for the TD3200 door controller, when using other models of door controllers, the F5-25 should be set to 64).
2. Whether the door is in place or not has been connected to the door.
3. Whether the door opener can output the door open signal when the door is opened. (The signal can be monitored by the door controller or measured using a tool)

8、Q: Why is the rectifier bridge of the brake circuit vulnerable to damage?

A: The rectifier bridge is damaged due to the reverse impact when the brake is released. An absorption device can be added to the brake coil: detailed connection and specifications:

9、 Q: Why is the elevator running process seriously jittery?

A:1. Check if there is any problem with the mechanical installation, such as if the guide shoe is too tight;

2. If it is a synchronous motor, try to modify parameters F2-06 and F2-07 (increase F2-06, decrease F2-07);
3. Perform motor self-learning again.

10、 Q: Why is it good or be bad at leveling, suddenly going up and down?

A: In the case of ensuring that the level sensor is installed correctly:

1. Re-run the motor self-learning;
2. If it is a synchronous motor, replace the encoder and re-run the motor self-learning;
3. If it is an asynchronous motor, try reducing the value of the no-load current F1-10 to 80%.
