elevator main board ThyssenKrupp MC2 Elevator pcb

hyssen Elevator MC2 motherboard problem classification analysis:

1. System data is lost, re-enter data, first change the motherboard jumper position, insert two BOOT 05 chips, the diagnosis shows AF0E, indicating success, then insert two MZ14 chips, the diagnosis shows AF0E, move the jumper, and DOWNLOAD V83 program.

2. After the system data is lost, re-entering the data fails. Use the clearing program to clear the memory, discharge the capacitor on the motherboard for 1 minute, and then re-enter all programs. It is damaged (next to the 4 relays, a resistor has been soldered on the new motherboard).

3. The motherboard A6FA cannot be entered. After checking, the A700 address is 00, which should actually be 01. The engineer set the software

4. After replacing the motherboard, the elevator stopped immediately when running in maintenance mode. The reason is: the circuit board sent to the construction site by the factory has not been taught. Only after teaching can it run normally. For circuit boards that have not been taught, the elevator must be run under 15AF.

5. There is no 24V output on pins 1 and 2 of X23. After checking the chip IC716 (model: ULN2003A) on the motherboard

6. Using V83 software, if the outbound call arrow is running by modifying the address (A461=01, A463=10) to realize the function of constant light, the OC42 alarm will appear. When this alarm appears a certain number of times, it will cause a crash.

7. Address A460 should be 80. If it is 00, there is no energy saving function.

8. For MC2 motherboards produced before 2003, X101 is a five-pin circuit board. If a six-pin circuit board is replaced, it is best to change A46B=00 (the original value may be 40). Reason: There may be problems after the door lock is opened. For example, the 7100 alarm may have a timing problem. For this type of fault, it is best to try other program chips..
