between batteries, controller,
charger or fuses caused by
loose connections, damaged
wiring, water ingress
Switch OFF the machine :
Remove Fuses
Check connections to batteries, charger and fuses for
loose wires or screws
Tighten loose connections
and replace damaged
components
Not accepting charge due to
faulty battery / cell
Check each battery Voltage individually to detect
defect unit 10.5V min
Replace batteries as re-
quired
Charger not functioning Check battery voltage and charge current ensuring
charger red fault light is extinguished
Replace charger
2 Flashes with pause Traction motor
disconnected
The motor has a bad
connection
The motor will not
operate
Check all connections and leads between motor and
controller
Tighten loose connections
and replace damaged
components
Motor disconnected
TCO activated
(Thermal Cut Out)
Motor failed to open circuit
3 Flashes with pause Traction motor
wiring trip
The motor has a short circuit
to a battery
Motor will not operate Check all connections and leads between the motor and controller
4 Flashes with pause Battery Lockout The battery charge level
has fallen below the
battery lockout level and
the controller is inhibiting
machine functions
Machine functions not
working
Check battery voltage and charge current ensuring
charger red fault light is extinguished
Charge batteries
immediately
Check each battery voltage individually to detect
defect unit 10.5V min
6 Flashes with pause Charger connected The controller is being
inhibited from driving, this
may be because the battery
charger is connected
Machine functions not
working
Remove charger to operate machine
7 Flashes with pause Machine inhibited E-Stop pressed Machine functionality
inhibited
Check E-Stop Release E-Stop and cycle
key switch
8 Flashes with pause Controller trip A controller trip is indicated Machine functions not
working
Check all connections and leads Tighten loose connections
and replace damaged
components
9 Flashes with pause Brake deactivated
or failed
Poor brake connections
Brake failure or deactivation
Traction drive
disabled
Check brake wiring and brake lever Replace brake or wiring as
necessary. Reactivate brake
by engaging brake lever
10 Flashes with pause High battery voltage Poor connections between
battery controller and traction
motor
Machine functions not
working
Check each battery Voltage individually to ensure
voltage < 14 volts
Check connections on controller batteries and traction
motor
Check combined battery pack voltage is < 28 volts
