2000 Electronic software running error, causing CPU reset.
2001 Power on or press the reset button.
2002 The 5V phase is less than 2.5V, and the system shuts down during power failure.
2007 Software false interrupt
2009 Hardware fake interrupt
2100 Too much slippage of the wire rope in the same direction as the elevator.
2101 The wire rope running in the opposite direction from the elevator is too slippery.
2103 Unlimited floor count, which is inconsistent with the actual number of well floors or exceeds the maximum or minimum floor limits.
2105 DZ input signal error
2106 DZ1 entered in the wrong order
2107 DZ2 entered in the wrong order
2108 The input sequence of 1LS is wrong, the elevator stops at the lower level, the DZ moves without 1LS signal, or the 1LS signal moves before the 1LS switch. It could be 1LS and 2LS working together.
2109 The 2LS input sequence is wrong, the elevator stops at the top floor, the DZ moves without the 2LS signal, or the 2LS signal moves before the 2LS switch. It could be 1LS and 2LS working together
2304 OCSS communication error.
2404 DCSS communication error.
2410 DCSS#1 timeout failure
2411 DCSS#1 Checksum error
2412 DCSS#2 Timeout fault
2413 DCSS#2 Checksum error
2414 LWSS Timeout fault
2415 LWSS Checksum error
2416 An unused DCSS address was received
2417 Received an unwanted DCSS address
2418 Sync error
MULTIDROP communication (DO2000,HPDS,LWSS)
2505 Communication timeout of MCSS and DBSS, or output buffer overflow.
2600 The elevator rushed through the stop position
2601 Curve Synchronization Error
Running logical state
2701 Five seconds after the operation of PREPARE to RUN or reset, the driver is not ready to run, and the time-out fault occurs.
2702 DBSS lock or release lock timeout.
2703 Received a DBSS drive failure from DBSS.
2704 Receive DBSS stop or stop information
2705 DBSS exceeds the torque limit
2706 Run times of the flat layer
2707 Recovery times
2708 Initialize run times
2709 During the flat floor operation, the elevator is outside the gate area. (the number of failures also increased in 2706)
2710 The elevator wasn’t ready to run for five seconds.
2716 Wrong sequence of operation when changing from maintenance operation mode to normal mode.
2717 TCI ERO INS input signal is inconsistent.
2718 TCI startup is unsafe.
2719 In the maintenance operation mode of the car roof, the elevator operation beyond the end station causes an emergency stop. TCI curve parameter adjustment is not good.
2800 The relative overspeed of normal, repair, recovery, reinitialization, learning, or replanar operation exceeds the absolute overspeed percentage.
2801 Tracking errors caused by normal, maintenance and low-speed operation speed exceeding the actual speed and command speed are allowed.
2802 The operation direction from PVC feedback is opposite to that of the instruction.
2803 During normal operation, the actual speed of the elevator at 1LS/2LS exceeds the corresponding NTSD setting value. SHUTDOWN will resume after the elevator stops slowing down with a predetermined deceleration.
2804 The elevator did not start during the scheduled time (DDP time), resulting in a timeout error. There is no wellbore signal input for a predetermined period of time during normal operation or reinitialization. It is possible that the slip of the wire rope loses traction.
2805 U/D relay input error. The action of feedback contacts of U/D relay is inconsistent with the reverse operation of instructions.
2806 DBP relay input error. The feedback contacts of the DBP relay are inconsistent with the required actions, or the LVC input is inconsistent with the desired state of the lock bypass.
2808 SC relay input error.
2809 DFC relay input error. In the case of open door and no action by the door, DFC signal still has input.
2810 DBD signal input error.
2811 The actual speed of the elevator in SS1/SS2 switch action exceeds the set speed of ETSD.
2812 Safety circuit
2813 The elevator’s safety loop disconnects at the DFC input point causing an emergency stop.
2814 FSO/ASO relay input error.
2815 EES detects errors. (NAO only)
2816 EES input error. (NAO only)
2817 Error setting of CODE switch on electronic board.
2818 Logical contradiction in door area of electronic board.
2819 Manual deceleration overtime.
