Code
Fault Name
Description
Err11
Floor plate
switch fault
The floor plate switch signal is active in normal state.
Err12
External signal
abnormal
1: There are A/B pulses in the stop state.
2: There is no A/B pulse within 4s after startup.
3: The number of A/B pulses for up step signals is smaller than the
setting of F0-07.
4: The number of A/B pulses for down step signals is smaller than
the setting of F0-07.
5: The left handrail pulse signals are very quick.
6: The right handrail pulse signals are very quick.
7: The two inspection signals are inconsistent.
8: The upward and downward signals are active simultaneously.
Err13
MCTE-PES-E1
board hardware
fault
1–4: The relay feedback is wrong.
5: The EEPROM initialization fails.
6: RAM check is wrong after power-on.
Err14
EEPROM data
wrong
-
Err15
Main and
auxiliary data
check abnormal
or MCU
communication
abnormal
The main and auxiliary chips are inconsistent in the following
aspects:
1: Software versions of the main and auxiliary MCUs
2: States of the two chips
3: Signal state of terminals X1 to X4
4: Signal state of terminals X17 to X20
5: Output
6: Phase A escalator speed
7: Phase B escalator speed
9: Braking-to-stop distances detected by the main and auxiliary
MCUs
8: The orthogonality of A and B pulses is not good and there is
jump.
10: The left handrail signal is instable.
11: The right handrail signal is instable.
12, 13: The up step signal is instable.
14, 15: The down step signal is instable.
101–103: The communication between the main and the auxiliary
chips is wrong.
104: Communication between the main and auxiliary chips fails at
power-on.
Err16
Parameter
abnormal
101: The calculated number of pulses for 1.2 times of maximum
braking-to-stop distance is wrong.
102: The calculated number of A/B pulses for step signals is wrong.
103. The calculated number of pulses a second is wrong.
