Metro Mobility S800 - Self-diagnostic Controller

Your scooter is engineered with a self-diagnostic controller which continuously monitors the operating
conditions of your scooter. If it detects a problem, it will indicate error message by flashing the READY
on the LCD and sounding audible will beep simultaneously. You should count the number of flashes and
beeps separated by a short delay between each sequence, and check the list below to see what kind of
problem has happened according to the number.
Number of
flashes/beeps
Represent
Fault
Solution
1
Battery power
low
power not
enough
The battery needs charging
2
Low battery
voltage
Power not
Enough
The battery needs charging
3
High battery
voltage
Too higher voltage, while
overloading or
climbing
Decrease speed while climbing
Check battery connection
4
Electric current
over limit
Electric current
over limit of motor
Check motor and relative wiring
connections
Switch off and wait a few minutes and
switch on
5
Free-brake issue
The freewheel level is on
Check the relative wiring of the
freewheel level
Confirm the level is on the correct
position
6
Accelerate the
variable resistor
issue
When turning on the
controller, accelerate
variable resistor isn’t on
the neutral position
Make sure the accelerate variable
resistor is on the neutral position
Accelerate variable resistor may need
to recalibration
7
Speed limited
variable resistor
issue
Accelerate variable
resistor, Speed limited
variable resistor or other
wiring issue
Check all the accelerate variable
resistor, Speed limited variable resistor
or other wiring
8
Motor voltage
issue
Motor and other relative
wirings issue
Check the motor and other relative
wirings
9
Other issues
Some inner issues in the
controller
Check all the connection and wirings
10
Pushing/
Slipping issues
The speed of pushing or
slipping is over limited
Switch off and on the controller
