PL001 comes with two Lithium batteries as the chairs power source. PL001 operates with the
control module delivering all programmed commands to the brushless motors. The joystick
control panel carries out directional commands as well as controlling the speed and power of
PL001. The charging port for PL001 is located on the Joystick Control Panel.

Power Supply Failure and Battery Failure
Problem Solution
Lithium battery over-current
protection cutting power
supply off
Connect the battery charger to the joystick control panel to re-
activate lithium battery
Poor battery connection Pull out the batteries and re-insert the batteries until a click
sound is heard
Faulty 5-pin connector
Use and set the multimeter to DC voltmeter mode, to measure
the voltage of the 5 – pin connector. If the voltage reading is
below the range of 23 volts, replace the 5-pin connector
Joystick Control Panel:
Faulty 4-pin cable
Use and set a multimeter to Ωresistance mode and follow the
circuit diagram. If open circuit or short circuit is found, replace
the faulty 4-pin cable
Battery casing deformed and
reduced battery life
Deformed casing of the Lithium battery is sign of the battery
reaching the end of its service life. Failing to charge the battery
regularly when the power is low will significantly reduce the
battery life. Please replace batteries immediately
Joystick Control Panel Flashing LED light Diagnostic Indicator
Sign Problem Solution
Battery is running low Re-charge or replace both batteries immediately
Joystick cannot deliver
signals to the control module
Inspect all cables and ensure connectors are firmly
connected or replace the joystick
Batteries are being charged.
An electronic drive locking
device is engaged to prevent
the chair from operating
Disconnect the 3-pin charger cable from the
Joystick Control Panel
Brushless motors fail to
move
a) Inspect all control cables are firmly connected.
b) Inspect all control cables to see if there are any
open or short circuits by using a multimeter.
Electromagnetic brakes
disengaged
Push the electromagnetic brake lever to the “Lock”
position

Electrical Troubleshooting – Use a Digital Multimeter
1. 5-pin XLR Plug voltage test
a. Follow below; set the multimeter to DC voltage mode. Follow below, to probe pin
#1 and pin #5 of the 5-pin XLR plug. The voltage reading should fall within the
specified range between 22V and 28V.
2. Motor’s internal short circuit or open circuit test
a. Follow below; set the multimeter to Ωresistance mode with the appropriate
resistance range, the red probe comes in contact with each pin hole of the 10-pin
plug. The black probe touches the motor housing to detect short circuits or open
circuits of the motor.
3. Battery test
a. Follow below; set the multimeter to DC mode with the appropriate voltage range.
4. 3-pin charging connector
a. Follow below; set the multimeter to Ωmode with the appropriate resistance range,
to probe each pin hole for open circuit or short circuit.
