1. Introduction
This guide is intended for use as a general reference by engineers
repairing faults on the Handicare 2000. The guide is structured as
follows: the first chapter provides general information about the
Handicare 2000, including how the Handicare 2000 should be tested,
where the components are located and how they react to certain
situations. The subsequent chapters deal with repairing faults.
Flow charts are used in some cases, where step-by-step choices have
to be made in order to find the cause of the fault.
There is room for improvement in every guide. If you have any tips or
suggestions, please let us know so that we can incorporate them.
We wish you the best of luck with your tasks and hope that this guide
will be of assistance.

Molex testing link
5. Testing
The circuits should be tested as follows:
• Use the electrical diagram to see which circuit you need to test
• Disconnect the Handicare 2000 from the power supply
• Connect the molex testing link to the pcb
• Ensure looms are removed from pcb before carrying out
continuity testing
• Set the multimeter to the “beep” or resistance or voltage test
mode
• Check that you are testing between the correct connector pins/
numbers.
• No “beep” or resistance means that the circuit being tested is
not complete.
• Voltages can be find on the electrical scheme
If there is a short circuit with the frame, hold one of the measuring pins
against the unit’s ground pin of the seat and push the other measuring
pins into the top of the molex testing link.

6. Display
On the lift is a display which shows a diagnostic code to help you to locate the
cause of the breakdown. The codes can be found on page 4/5 and in the user-
and installation manual.
7. The toggle
The lift is operated by the toggle on the armrest. The toggle as well
as the key switch or the button for the powered footrest raiser can be
swapped from right to left on side.
The lift will not ride when the armrests are in the folded position. It does
however operate on the remotes.
During the ride the diagnostic
display show “8” or “9”.
An installation toggle loom
can be used to ride the power
pack without chair. (art.
Nr.181001.50083).
In case of a public building when the key switch should switch off the
toggle but the remotes should stay operational, the key switch needs to
be transferred from the safety line to the control line.

The general safety edges
The general safety edge prevents the lift from moving further in both
directions.
The diagnostic code shows “0” when the toggle is moved in either
direction if the safety edge is obstructed.
The following switches have been included in the general safety edge:
• Seat swivel switch
• Overspeed governor switch
• Key-operated switch
• Final limit switch
• The emergency stop
• The handwinder switch
10. The batteries
Two 12V 7,2 Ah maintenance-
free lead-acid batteries are used.
They have an expected life span
of three years.
If the output voltage of one of
the batteries is at least 5V less
than that of the other, it can
be assumed the battery is faulty. If the voltage between the batteries
varies, there is something wrong with them.
Guarantee
No guarantee is provided for the batteries. However, we do ask that
you report any complaints to us, stating the identification number on
the battery.

11. Charging power supply
The battery charger is suitable for
an input voltage of between 100V
and 240V. The output voltage is 33
V=. The charging current is 1 A.
There are different diagnostic codes
if the lift requires charge
Code 1 and 7: When the battery voltage is very low (maybe down to
10%capacity left in batteries), this fault code will appear. When the
lift docks on to charge contacts, the lift will not drive off the contacts.
1 will flash. Lift will only drive off if battery voltage has recovered
approximately three quarter capacity. Another way of driving off the
contacts is if lift is powered “off” then back “on” but as soon as lift
docks on contacts, process will repeat again. This fault code is linked
to fault code 7 but the code 7 is not usually seen as code 1 takes
priority.
Code r: This fault will occur when the lift is charging. If the power
supply is disconnected while the lift is charging, the r code will display.
A fault with the 33V power supply where the power supply cannot
supply current to charge the batteries will also show this code.
Code U: This fault occurs when the lift has fully charged the batteries
and is in float mode. When the 33V power supply is disconnected, the
U code will display.
Code E: This fault appears if the batteries are low. The main relay on
the board is rated for 24VDC operation so the low voltage will give a
false fault condition.

Logic
The grey communication loom provides a link between the MS125 pcb
and the 126 pcb.
The 126 connection on the MS125 pcb output is between 8-12
volts. Each time a 126 pcb is connected, the reading will drop by
approximately 0.8 volts as communication between the two pcb’s is
established.
The 126 pcb dip switch settings tell the MS125 pcb what powered
option is connected. Each dip switch setting is looking for different
parameters to determine when and where power should be applied to
the attached motor.
When the parameters are met, the MS125 pcb passes the battery
voltage through the communication loom to the 126 pcb. The 126 pcb
then reduces the output to the correct voltage for the attached motor
to power the option. Depending on which option is attached, voltage
would be applied to the motor for a set time or until the motor has hit a
stop, the 126 pcb has a stall current.
In case of a failure on the communication circuit, the lift runs, but the
options don’t function.
Powered swivel chair
The powered swivel chair swivels at the top and is operated from the
toggle. The lift shall be on the upper end limit switch and the board

Quick Reference Guide Handicare 2000

should detect the charge voltage. The powered swivel chair can be
operated manually in case of emergency.
Powered footrest raiser
The powered footrest raiser is powered from a button under the armrest
or from a switch between the 2 seat parts. The powered footrest can be
activated all along the track.
The pcb used for the powered footrest raiser does not communicate
with the main pcb. The safety and the limits are build into the footrest
motor.
The foldable hinge
The foldable hinge is operated by the toggle. From the top of the stairs,
the toggle is pushed in the down direction. The lift will drive down the
track until it reaches the intermediate charge contacts. The lift will stop
at this point. Keep the toggle pushed in the down direction. After a
short pause the hinge will lower.
On the rail at the top and just above the foldable hinge are 2 contacts.
The contact on the upper tube is for the communication and the
contact on the lower tube is for the charging.
On the backside of the unit is a foldable hinge enable contact. This
contact shall be activated by the ramp to enable the foldable hinge to
move. At the same time the cupper strip in the power pack shall have
contact with the cupper strip on the rail, so the lift “sees” 33V=. In
case of a power down the foldable hinge will act on the foldable hinge
enable contact only.
On the rail are 2 switches to control the end position of the hinge and
to enable the lift to drive in case the hinge is completely (un) folded.
On the main board the dipswitch to enable foldable hinge shall be
activated. And on the board in the electric box on the rail shall be
activated. Consult the electric scheme for the right setting off the
dipswitch.
