Error
Code
Definition
Possible Solution
LER=11
Top terminal 1 switch signal lost
Top limit switch enables before top terminal 1 switch or top
terminal 1 switch signal lost.
LER=12
Total floor setting error
Check total floor number match actual floor number.
Check leveling inductor plates on every floor.
LER=14
Two leveling inductors cannot trigger
together
Leveling inductor plate on this floor cannot cover both
inductors or misses one leveling inductor.
LER=15
Press "ESC" in the middle of hoistway
parameter learning process.
Cancel the learning by pressing "ESC".
LER=17
Up/Down leveling switch enable at
same time
Wiring of two switches is parallel connection by mistake, or
bottom limit switch is installed close to 1st floor leveling
position.
LER=18
Hoistway data saving error
▲Please contact supplier at once.
LER=19
Both leveling switch signal enable
together when arrive at top limit switch.
Move up top limit switch.
LER=20
Bottom limit switch too high
Lower the bottom limit switch.
LER=21
When elevator reaches top limit switch,
bottom terminal 1/2 switch is valid.
Check the switches position and their wirings.
LER=22
When elevator start from bottom limit
switch, top terminal 1/2 switch is valid.
Check the switches position and their wirings.
LER=23
No pulse feedback after starting.
Check the wire of PG card.
LER=24
The up and down door zone signals are
opposite in hoistway learning.
Check installation positions of up and down door zone
sensors, exchange their wires.
Note: System has 2 top and 2 bottom terminal switches for elevator speed >2.0m/s
