Multimeter Tutorial
MULTIMETER
The Multimeter
The multimeter is one of the most useful tools in the
toolbox. It can be used to check wires, shorts, voltages,
resistance, all manner of electrical circuits. This tutorial
is designed to help clarify the symbols and socket options found on various multimeters.
The Probes
PROBES
Probes connect the meter to the circuit. Simply touch
them to the connections you want to measure and read
the display. Obviously, this depends on how the meter
is set up, and what is being measured.
The Ports
1. The Common Port.
Generally, the black probe plugs in here (negative)
and as the name suggests, it’s the common element to all of the testing circuits. Think of it as the
ground rail.
2. Voltage, Resistance and Continuity port.
This is commonly used option. Connect the red
(positive) probe to this port when using any voltage readings, resistance readings or when checking wire continuity (explained in more detail later
in the tutorial).
3. Current up to 300mA.
This port is used for “counting electrons” in a
circuit, and thus their rate of flow (current being
the flow of electrons). You’ll notice that this side
is “fused”, so that you don’t end up melting the
meter’s circuits.
4. Current up to 10A.
Same as above, except it can take more current,
as the name suggests.

INTRODUCTION
Symbols
This section describes the basic symbols used in a typical multimeter.
AC
This symbol means alternating current. Use this when you want to test
something that has AC current running through it. Typically you’d want to test
the voltage of an inverter (for cold cathodes or neons) or a similar device.
DC
This means Direct Current. This is the type of electrical power produced by
a battery. With a battery connector, the black wire(s) should be connected to
the negative(-) terminal of the battery and should be considered the common
ground. The red wire(s) should be connected to the positive(+) terminal of the
battery and is considered the “hot” lead.
Voltage
This means Voltage or Potential Difference. This measures the potential
difference between the two probes. To measure voltage, connect the positive
probe to a port that is marked “V” or Voltage.
Note: “mV” means milli-volts .001 Voltage
Current
Technically, this term is incorrect. It should be “I” but since current is
measured in Amps and the readout value is in amps, the symbol makes
sense. This measures the current that is flowing through the part of the circuit
between the two probes (the meter itself). Typically, you need to plug the
positive terminal into a port marked “A” or Current. You need to put the meter
“In Series” in the circuit to use this feature correctly.
Resistance
This symbol means Resistance and is measured in Ohms. You can use this
setting to measure the resistance between two points; for example across a
piece of wire or a resistor (to check its value). If you don’t have a continuity
check, then this can be used to check for shorts. Any value below 0.05 Ohms
constitutes a short, meaning that whatever the probes are attached to is
connected electrically.
Continuity
A commonly used function. Basically, what it does is put a current through
the two terminals (the same as the Ohm-meter function) and if the resulting
value is within the “contact” range, it will beep. This feature found on some
multimeters enables you to check for shorts without taking your eyes off your
work. Other meters may have a light that turns on when a short is found.

Health and Safety
Good Working Practices
While working on powered mobility products, it is essential to observe good working
practices. Below are a series of safety guidelines and recommendations. Please note that
these precautions are intended to serve only as a guide, not to supersede or replace any
safety statute, NHS or other safety regulations.
General
• Always wear suitable protective clothing when handling batteries.
• Always wear suitable eye protection when drilling or inspecting.
• When safe to do so, wear protective gloves when handling the running gear or
batteries, as these parts are exposed to paths, parks etc.
• If the drive wheels have to be raised off the floor, always use a pair of axle stands
to secure the vehicle.
Battery Safety
•
•
•
•
•
•
•
•
•
•
•
•
•
•
Use extra caution when working with batteries.
Always make sure that the batteries are disconnected from the vehicle before
commencing work.
Always check that the battery charger is disconnected from the vehicle / batteries
before commencing work.
Do not smoke.
Keep batteries away from all sources of ignition.
Do not place objects on the battery tops.
Always try to keep someone within earshot of your work area so that they may
come to your assistance if needed.
Always wear personal protection when handling batteries, including, eye/face
protection and gloves.
Make sure there is easy access to soap and water in case of acid spills.
Avoid touching eyes or unprotected parts of the body while working on batteries.
Remember that non-sealed batteries can contaminate any packaging, housing,
or boxes they may have been transported in so handle all packaging with care,
especially during disposal.
If battery acid should come into contact with bare skin or clothing, be sure to wash
contacted area immediately, using plenty of soap and water. If battery acid enters
the eyes, flush with running cold water for as long as possible while medical help
is being sought.
When the tops of batteries are exposed, take extra care when working on or
around the terminals.
Do not allow metal tools to drop on to or touch the exposed terminals of the
batteries or other exposed connections, as this could cause a short circuit, which
may result in an explosion.

INTRODUCTION
•
•
Remove personal items of jewelry, such as rings, watches, chains etc.
before working on batteries. Such items could cause short circuits resulting
in serious burns.
Batteries are constructed of heavy materials. Therefore moving batteries
requires appropriate lifting techniques. Safety footwear should also be worn.
In addition, disposal of old batteries requires correct procedures. Contact
your local authority for their recommendations.
Battery Chargers
•
•
•
•
•
Remember battery chargers are connected to household current.
Always observe all guidelines and laws relating to electrical equipment.
Never operate the battery charger in wet or damp conditions.
If you think that the charger has been exposed to water or excessive
dampness, do not use it. Return the unit to the dealer/supplier for inspection/
replacement.
If you think the battery charger is defective or is visibly damaged, return the
unit to the dealer/supplier for inspection.
EMI Warnings
•
•
•
•
EMI means electromagnetic (EM) interference (I). EMI comes from radio
wave sources, such as radio transmitters and transceivers. A “transceiver” is
a device that both sends and receives radio wave signals.)
There are a number of sources of intense EMI in our daily environment.
Some of these are obvious and easy to avoid. Others are not, and we may
not be able to avoid them.
Powered wheelchairs, although tested in accordance with EMC guidelines,
may be susceptible to electromagnetic interference (EMI) emitted from
sources such as, radio stations, TV stations, amateur radio (HAM) transmitters,
two-way radios, and cellular phones.
EMI can also be produced by conducted sources or electro-static discharge
(ESD).
What effect can EMI have?
1. EMI, without warning, can cause a power chair to:
• Release its electronic brakes
• Move by itself
• Move in unintended directions.
• If any of these occur, severe injury could result.
2. EMI can damage the control system of a power chair, resulting in a safety
hazard and/or costly repairs.

INTRODUCTION
Sources of EMI
1. Hand-Held Transceivers: The antenna is usually mounted directly on the unit.
These include:
• Citizens band (CB) radios
• “Walkie-talkies”
• Security, fire and police radios
• Cellular phones
• Lap top computers with phone or fax
• Other personal communication devices
Note - These devices can transmit signals while they are on, even if not in use. The
wheelchair should be switched off when not in use.
2. Medium-Range Mobile Transceivers: These include two-way radios used in police
cars, fire engines, ambulances and taxi cabs. The antenna is usually mounted on
the outside of the vehicle.
3. Long-Range Transceivers: These include commercial radio and TV broadcast
antenna towers, amateur (HAM) radios and alarm systems in department stores.
NOTE- The following are Not likely to cause EMI problems: Lap-top computers
(without phone or fax), cordless phones, TV sets or AM/FM radios, CD or tape
players.
EM energy rapidly becomes more intense as you get closer to the source. For
this reason, EMI from handheld devices is of special concern. A person using one
of these devices can bring high levels of EM energy very close to a power chair
without the user’s knowledge.
Immunity level
The level of EM is measured in volts per metre (V/m). Every power wheelchair can
resist EMI up to a certain level. This is called its “immunity level”. The higher the
immunity level, the less the risk of EMI. It is believed that a 20 V/m immunity level will
protect the power wheelchair user from the more common sources of radio waves.
The configuration tested and found to be immune to at least 20 V/m is: QuickieRhythm
and Groove power wheelchairs with a right-handed mounted joystick system, 18” seat
width, 18” seat depth, dual-post height-adjustable armrests, fixed tapered legrests
with one-piece solid footplate and Gp 24 gel cell batteries.
The following dealer installed speciality input devices have an unknown effect on the
immunity level because they have not been tested with the Delphi control system:
• Breath Control (“Sip n Puff”)
• Tri-Switch Head Array
• Proximity Head Array
• Proportional Mini-Joystick/Chin Control
• Buddy Button
• Wafer Board

INTRODUCTION
Electro Static Discharge
To help prevent Electro Static Discharge (ESD) the following proper handling
techniques should be followed:
ESD:
•
•
•
•
•
•
•
•
Do not place Printed Circuit Boards or their containers near sources of strong
electrical fields (such as above a CRT).
To avoid the occurrence of static charge or discharge due to friction, keep
the Printed Circuit Boards separate from one another and do not stack them
directly on top of one another if not protected by antistatic bags.
Store each Printed Circuit Board in an antistatic bag with an external cushioning bubble-wrap layer until assembled to wheelchair. Antistatic bag must
have metal content to protect the printed circuit board. Gray bag protects
from ESD, pink bag or bubble wrap does not protect as well.
Always wear an ESD preventive wrist or ankle strap when handling electronic
components. Connect one end of the strap to an ESD jack or an unpainted
metal component on the system (such as a captive installation screw).
Handle Printed Circuit Boards by the edges only; avoid touching the Printed
Circuit Board and connector pins.
Place any removed Printed Circuit Board on an antistatic surface or in a static
shielding bag.
Avoid contact between the Printed Circuit Boards and clothing. The wrist
strap only protects the card from ESD voltages on the body; ESD voltages
on clothing can still cause damage.
Make sure that the Printed Circuit Board power is off by disconnecting the
seating harness prior to attaching or removing printed circuit board.
Printed Circuit Board Flexing:
• The printed circuit board has surface-mount components that may break
when the board is flexed. To minimize the amount of board flexing, observe
the following precautions:
• Hold the printed circuit board only by the edges.
• Do not place the printed circuit board on a hard surface.
• Tighten board mounting screws only hand tight (torque12.4 in lbs/1.4Nm) in a
cross pattern to reduce stress on mounting holes and PCB board material.

Batteries
Safety
If mishandled batteries can be dangerous and hazardous.
•
•
•
•
•
•
All mobility batteries, whether wet type or gel/sealed type, contain lead
and sulfuric acid. Both of these materials are toxic and in the case of
sulfuric acid, highly corrosive. Additionally, when batteries are charged,
they produce hydrogen gas which is “highly” flammable and can cause
explosion. This is why proper handing is mandatory at all times.
Battery explosion - This is frequently the result of too low an acid/electrolyte
level in the battery, which allows high concentrations of hydrogen to build
up. This is possible with all batteries if improper charging or battery failure
occurs, but not common in gel/sealed batteries.
< KEEP SPARKS AND FLAMES AWAY FROM BATTERIES >
Burns - dropping a wrench or screwdriver across battery terminals results
in sparks, and intense heat. Improper assembly of battery boxes or battery
box wiring may short the battery through the wiring and produce a possible
electrical fire.
Electronic damage - batteries that are improperly wired can short out
electronic chair components resulting in expensive repairs.
Pollution - improper disposal of batteries could damage the environment.
All batteries should be disposed of through a reliable battery recycler.

Battery Diagnostics
How Long Should Batteries Last?
An average of 1 to 1.5 years.
Factors that affect battery performance:
• Maintenance - Poor maintenance.
• Charging - Improper charging shortens battery life.
• Chair Components - Malfunctioning electronics, bad motors, electric brakes,
and corroded wiring are just some of the factors that may affect battery life and
performance.
Battery Servicing and Replacement
Automobile batteries, which are used for starting, are tested with a load tester to
assure a high rate of energy production in a short burst.
The voltmeters on load testers are not accurate enough to establish a
state of charge.
Deep-cycle batteries produce energy more slowly and are designed to hold up to
constant discharging and recharging. Testing a deep-cycle wheelchair or scooter
battery requires different procedures than an automobile battery.
A routine for testing deep-cycle batteries should follow these guidelines:
Never replace just one battery at a time. This will create an imbalance when charging
and ultimately damage both batteries.
Check batteries for a voltage difference. A voltage difference of more than .4 volts D.C.
is a true indicator of a bad battery.
Voltage test - A dead battery cannot be effectively tested, yet many people mistakenly
try to do just that. Any battery that reads 11.0 volts or less is technically dead.
To perform any testing, especially a load test:
A. Batteries must be charged
B. The top charge must be taken from fully charged batteries if charge rate has just
finished.
•
•
•
Load Test - This test can only be done on fully charged batteries and can
diagnose one type of problem, an internal short.
Capacity/ Discharge Test - This is the only accurate way to test a deep-cycle
battery for adequate running time. The problem with this test is that it is time
consuming.
Current / Voltage check with a regular interval check - Another way of truly
knowing how much time your battery will last is also time consuming.

REMEMBER: IT IS THE RESPONSIBILITY OF THE
INSTALLER TO KNOW WHAT KIND OF BATTERIES
TO INSTALL IN THE CUSTOMER’S WHEELCHAIR!
•
•
•
•
Deep-cycle batteries are designed to be
discharged and recharged on a regular basis.
Starting or automotive type batteries use a rapid
burst of power to start an engine and are quickly
recharged by an alternator or generator. They
are rated by cold cranking amps, a measure that
has no relevance to wheelchair application.
Marine and RV batteries frequently are not
deep-cycle as they are often used for starting
engines.
Only use Deep-Cycle sealed type batteries
in a wheelchair.

It has a clearly designated RED and BLACK connector
which connect to the Positive for RED and the Negative for the BLACK with JUMPER (White) joining the
system. The system has a 100 amp non-removable
fuse built into the Cable and a removable 15 amp fuse
for Auxiliary Power.
Fig 1.10
Inspecting the Fuses
Remove caps on each of the two 15 amp fuses and
visually inspect. Insure there are no breaks in the fuse
material. If continuity is still in doubt, unplug fuse from
holder and check resistance across fuse blades. Zero
resistance indicates a usable fuse. Infinite resistance
indicates a non-usable fuse.
The 100 amp fuse must be checked by measuring their
continuity. Zero resistance indicates a usable fuse.
Infinite resistance indicates a non-usable fuse. The
100 amp fuse is not replaceable, the harness must be
replaced.

Battery Chargers
Chargers and Charging
• Use the wheelchair manufacturer’s automatic charger for all routine
charging.
• The best recharge point for deep cycle batteries is roughly at 50%
discharge.
• Never run batteries completely flat [total discharge].
• Do not purchase automotive chargers. They are not designed to charge
deep cycle batteries and will quickly ruin gel/sealed batteries.
• Do not use chargers designed for wet battery charging with gel/sealed
batteries; their charging voltages are different.

Motor Encoders
Introduction
Encoders allow chairs maintain a straight line while
driving on uneven terrain and allows the usage of
Switch Controls without the normal veering of other
products. It does this by 5 individual Hall Effect Sensors
that will detect 1 degree per 360 degree rotation of the
wheel by means of the Encoder. Encoders are simple
to add on and operate with our Delphi Electronics. The
following details will show you
what parts are necessary and how it plugs into the
module as well as programming.
Fig 1.47
Fig. 1.47 shows the Encoder mechanism and the
Plastic coupler which connects to both Motor Shaft and
Encoder Assembly. This procedure is done by removing
the Brake cap and using the Same 3 Screws that were
used initially.
Your next step is to plug the Encoder Plug into the control Module (Fig 1.48) with Symbol seen in Fig 1.49.

Suspension
The Quickie Rhythm base has a special 4-bar
suspension system that pulls the front caster wheels
up over curbs, while simultaneously maintaining
independent suspension on the remaining four wheels.
•
•
•
•
The front caster housing pivots horizontally,
which absorbs front impact. Then the tension
between the caster and the drive wheel literally
pull the caster up over the curb.
When only going over rough terrain, the
connecting belt allows independent suspension
of the front casters as well as the drive wheel
The rear casters also feature independent
suspension.
All 6 wheels suspend independently and remain
in contact with the ground.

Anti-pitch Timing Adjustment
For Rhythm, each rear suspension element controls
the pitch damper mechanism on that side of the chair.
Timing of the initiation of the anti-pitch function on the
Rhythm can be accomplished by the following method.
• Place the chair on a pedestal so that the drive
wheels are suspended off of the riding or work
surface.
• To allow a clearer indication of anti-pitch function,
move to the front of the chair and remove the
6mm hardware that secures the anti-sway bar
end links to the motor mounts (Fig. 1.60).
• Lift the rear caster so that the black rubber pad
on the front of the rear shock mount is against
the chassis tube (Fig 1.61).
• The motor on that side of the chair should move
freely on its pivot and the anti-pitch tube.
• Slowly lower the rear suspension so that the
black rubber pad on the front of the rear shock
mount separates from the chassis tube (Fig
1.62).
• After the rubber pad separates from the chassis
tube the effort required to move the motor about
its pivot should increase substantially. This is
the pitch damper increasing the suspension
damping level.
• The increase in motor movement effort should
take affect before the rubber pad has separated
from chassis tube by more than 1/8”. This
constitutes pitch damper “timing”

Adjusting the timing of the anti-pitch effect is
accomplished by rotating the nut at the end of
the anti-pitch actuation cable at the anti-pitch
housing. The anti-pitch housing is located on
the stainless steel anti-pitch shaft inboard of
the drive motor. (Fig 1.63) (NOTE: The free
threads seen between the nut and the cable
rotary barrel indicate that this anti-pitch is fully
engaged.)
As seen, the barrel end of the cable has
a hexagonal shape and while an adjustable
wrench could be set to fit this portion of the
cable, a vise-grip type of pliers would be better
suited to this application.
Adjusting the nut clockwise will increase the
amount of suspension travel prior to anti-pitch
damping engagement. Adjusting the nut counter
clockwise will reduce the amount of suspension
travel prior to anti-pitch engagement.
After evenly adjusting the timing of the anti-pitch
on each side, reinstall the 6mm anti-sway bar
and attaching hardware, then set torque to 6
ft-lbs or 8.13 Newton-meter.
Remove the chair from the pedestal. The
procedure is complete.

Heels are exchangeable by removing the 4 Torx screws
and separating the heel from the main body of the hand
control. Disconnect the cable from the heel to the main
body of the control (where applicable), and ensure that
the Main Bus cable is detached from the heel. Take the
new heel and perform the reverse operation to fit it to
the main body of the Hand Control.
Wrist Rests are removed by loosening the two Torx
screws in the base of the Rest, splitting the Rest into 2
halves and removing a further 2 Torx screws that hold

Wiring
• Before making any connections to the Hand
Control, disable the Wheelchair by disconnecting
the Batteries and/or elevating the drive wheels.
• Use only Sunrise Medical approved wiring
Harnesses to connect the Hand Control.
• Wiring should be suitably restrained and fastened
to the wheelchair to prevent snagging and to
ensure that there is no strain on connectors.
• Take particular care when routing and securing
cables on moveablestructures, such as Tilt, Lift
and Recline etc. Such moving structures have
the potential to crush and shear wiring, causing
potential electrical issues.
• To maintain EMC compliance, ensure that
wires are routed as per Sunrise Medical
recommendations.
Note: bottom 2 pins 3&4 can be used to measure battery voltage.

Control Operation Description
The Motor Controller is a 70 amp control module for
QC and 100 amp for QR. When used on flat terrain it
will draw approximately 10 amps (+/- 2). On a steep
incline or curb, it will draw up to 70 amps of current
to give the motors a power boost for 10 seconds. If
required, it will deliver 35 amp output for an additional
100 seconds. Most controls would either shutdown or
go into full current rollback after going for that length
of time. The QC Motor Control will continue to deliver
output at 25 amps.

Operate the wheelchair by moving the joystick (or other control device) to full speed forward. Verify that the
command is forward and even both left and right.
Monitor the Motor Current, Motor Voltage and Motor RPM for both the left and right motors. Refer to the folThe Motor Resistance is the factory default motor compensation. Typical programmed value is .05 Ohms.
The Motor Voltage for each motor should increase evenly.
If the voltage is not even, verify that a Veer Compensation has not been programmed into the chair.
If the Motor Voltages are still not even, the Motor Controller may be defective. Verify that there are no faults
recorded in the Fault section of the Quickie iQ or HHP.
The Motor Current should be even for both motors when the Motor Voltages are equal. A typical value for
the Rhythm or Groove motors with the gear box disengaged is 4 to 6 amps. Cold motors may indicate higher
current.
Excessive current may be caused by bad bearings, defective or shorted motor windings, or a dragging park
brake.
The Motor RPM should be even for both motors when the Motor Voltages are equal.
If the Motor RPMs are not equal and the wheelchair contains IntelliDrive, suspect a bad motor encoder or
motor controller.

Gear Box Test
Perform the following steps to electrically test the gear box.
1. Prior to completing this test, complete the Motor Test. A defective motor may also appear as defective Gear
Box.
Warning
If the following step is not completed the wheelchair may move unexpectedly possibly causing injury.
2. Elevate the wheelchair by placing blocks under the battery box. Verify that the drive wheels are completely off
the ground and free to rotate.
3. Engage the motor gearboxes.
4. Repeat the Motor Test. Refer to the following notes:
• Extra drag is put on the motors when the gearboxes are engaged. This extra drag shows up as an increase
in Motor Current.
• An increase in motor current by 1 amp is typical if the gearboxes are warm.
• If the gearboxes are cold, the increase in current may be more.
• Fully warm them prior to making a decision to replace the motor/gearbox assembly by running them for 30
minutes.

Actuator Tests
Notes:
• The seating actuators contain encoders that provide position information to the Motor Controller or QMAC.
• Counter Reset Switches (CRS) automatically provide re-home information to the Motor Controller or QMAC.
The re-home function occurs when the actuator moves across the CRS.
• Failure to operate the seating system far enough to operate the CRS over time may cause the controller
to lose counts and to not return to programmed position. Encoder errors may also occur if the CRS is not
exercised periodically.
• Encoder errors are often cause by “homing” errors. Re-Home the wheelchair anytime encoder errors are
present.
• Creep speed (profile) will be active anytime the back angle is 15 degrees from vertical. This angle may be
from recline, tilt, or a combination of the two.
• Creep speed (profile) is active anytime the seat elevator is active. Raising the seat approximately 1/8” will
invoke creep speed.
• Creep profile is a percent of maximum wheelchair speed. It is adjustable using the HHP or PCSS. However,
the speed can never exceed the maximum safe speed predetermined by Sunrise Medical.

The Perfect Fit System
Theory of Operation
The Recline Portion of the Perfect Fit Seating System
uses dual keipers to operate the back. Each keiper is
powered by independent 24 VDC motors. A cogged
belt connects the motors to the keipers.
The keipers are similar to those used in the automobile
industry to recline seat backs. A hinged rod
connects the left keiper to the right keiper to ensure
synchronization.
An optical encoder is mounted on the left keiper
assembly to record the rotation of the keipers. The
control module decodes this signal and calculates the
back angle.
A conventional joystick, or other input device, sends
actuator commands over the CANBUS line to the
control module. If a QR-MAC is also incorporated, the
commands are routed to it as well. The control module
or QR-MAC sends operating voltage to a PC board
mounted on the seat back.

Fig 3.48

SEATING SECTION
The PC board has several functions, including routing
the voltage from the controller module to the recline
actuators. The optical encoder sends its signal to
the PC board. The PC board routes this signal to
the control module where it is analyzed for correct
operation and position.
Encoder Reset Switch
For recline, the PC board receives a signal from a
rocker switch that is mounted in the center of the back.
This switch (the Encoder Reset Switch) is operated
by a sliding link connected to a strut. Its purpose is to
synchronize the optical encoders with the back angle.
This signal is sent to the control module.
Fig 3.49
The tilt system contains an 18-degree micro switch that
informs the computer when the tilt is at 18-degrees.
The purpose is to reset the encoder circuit each time
the chair is tilted past 18-degrees. With the exception
of the legrest system, the other seating functions reset
during the operation by recording the actions of microswitches located within the actuators.
Two reed switches are mounted on the same bracket
that houses the Encoder Reset Switch. One reed
switch is the End of Travel (EOT) “Home” for the up
direction of the actuator, and the other reed switch
is the EOT for the “Back”, or down direction, of the
actuator. These signals are sent to the PC board
which interupts the actuator current when the seatback
reaches either end-of-travel.
The actuators are connected to the PC board. The
actuator drive voltage is provided by the control module
and routed through the PC board to the actuators.
Creep (speed reduction) and drive lockout are
controlled by the Delphi system. Twelve degrees of tilt,
40 degrees of recline, or any lift will cause the chair to
drive in creep speed.
Drive lockout will occur anytime two or more of the
functions (tilt, recline) are causing the chair to drive
in creep speed. Example, if the chair is tilted past 12
degrees and also reclined more than 40 degrees, the
chair will not drive.

Power Recline with Power Shear Reduction
The New Power Recline with Power Shear Reduction is modeled after the Quickie Smart Seat with the additional
enhancement of operation by the Quickie iQ Electronics powered by Delphi. Electrical adjustments for the New
Power Recline are either by using the HHP or Quickie iQ. The three new adjustments available using the HHP or
Quickie iQ are:
1. Shear Program – This program allows the use of the HHP or Quickie iQ program to map the shear amounts
in relation to the back angle.
2. Enable – Enable selects the Power Shear Program.
3. Tuning Factor – Tuning Factor smoothes the Shear Program (shear mapping) to prevent jerky shear reduction.
The factory setting is 10 and the range is 1 to 100. One (1) is the smoothest setting, 100 follows the shear
map exactly.
The recline system uses encoders in the actuators to provide seat position to the Delphi system. This system has
been improved over the Smart Seat by providing automatic “re-home” capabilities. Automatic re-home is performed
anytime the seat is operated past a certain point and micro-switches are closed. These micro-switches, known as
Counter Reset Switches (CSR), tell the Delphi system the exact position of the actuator.
Automatic speed-reduction, known as Creep, is controlled by the position of the back. Anytime the back angle is 15
degrees past vertical in any combination of Tilt or Recline, the wheelchair reverts to a programmable Creep Profile.
This profile may be modified by either the HHP or Quickie iQ to run slower than the factory settings. Creep speed is
a percent of maximum Creep speed programmed by Sunrise Medical.
Prior to performing any troubleshooting, “re-home” the recline and shear system using the HHP.
It is also a good idea to use the HHP or Quickie iQ to troubleshoot the system prior to performing any component
testing. Refer to Fault Isolation Procedures Using Quickie iQ or HHP in this tech manual.
Once the wheelchair has been re-homed and then tested using the HHP or Quickie iQ, complete the following sections to test the individual components.
To remove the rear shroud for service work, refer to the section covering Recline Actuator Removal in this tech
manual.

the tilt is more than 16 degrees, the switches opens and invokes “Creep” Speed. Creep speed is a
predetermined speed programmed at time of manufacture. Creep is indicated by a “turtle” on either
the color Joystick or Omni.
1. Tilt the seat all the way back and observe the
hand control or Omni to see if the turtle symbol is
displayed.
If the turtle (A) is displayed (fig 5.5.1), contact
Sunrise Medical Technical Service for assistance.
A
If no turtle is displayed, continue to step 2.
2. Tilt the seating system beyond 16 degrees.
fig. 5.5.1
3. Locate the 6-pin connector on the rear of the
tilt. (fig 5.5.2). Disconnect the harness from the tilt
module.
4. Test the micro-switch by performing the following
test:
a. Ensure that the tilt is beyond 16 degrees.
b. Use the multimeter and measure continuity
rbetween the indicated pins on the pin connector
mounted on the tilt. When the seat is tilted the
indication should be open (fig 5.5.3).

Tilt Will Not Operate
The tilt actuator used in the tilt system receives power through a 6-pin connector located at the rear
of the tilt. The actuator also contains micro-switches that open at the end of their stroke to prevent
stressing of the tilt system. Around these micro switches are diodes that allow reverse power to flow
to the actuator when reversing direction.
1.
Selected the tilt mode on the Joystick or
Omni. (fig. 5.6.1). Operate the joystick and listen
closely to the control module for a click. This click
indicates that the control module is closing the
power relay inside and supplying power to the tilt
actuator.
If no click is heard, replace the control module or
ISM
If click is heard proceed to step 2.
2.
Verify that tilt is selected on the hand
control. Operate the joystick and listen closely
to the tilt actuator. If the actuator appears to be
running but the tilt is not moving, replace the tilt
actuator.
fig. 5.6.1
3.
If the actuator does not appear to be
running, locate the 6-pin connector on the rear of
the tilt actuator (fig. 5.6.2) and disconnect it.

Warning: Use caution in the next step. Do not short the leads of the Multimeter together
or damage may occur to the control module.
5.
At the 6-pin connector on the cable leading
to the control module, verify that battery voltage
is present between the indicated pins (fig. 5.7.1).
Note: The polarity of the voltage is not important
since it is reverses when the opposite direction is
selected.
6.
If voltage is not present, replace the cable
leading to the control module. Retest with new
cable. If the new cable does not correct the
problem, replace the control module.

The Power Recline System has 3 Possible Minimum angles 90, 95, 100 degrees. This angle is set
by programming. The minimum angle for each chair is based on how the chair was ordered. The ISM
(Intelligent Seating Module) calculates the degree based on the resistance of the recline actuator’s
internal potentiometer. To determine what angle your back should be calibrated to you can contact
Sunrise Customer Service to see confirm what angle was requested when the chair was built. (Making
changes to this preset “Home Angle” will require a program change.) You can confirm the recline

4.
Reinsert and tighten the bolts securing the
pivot point.
5.
As the pivot point is raised, the Recline
actuator and gas strut MUST also be raised
an equal amount. This is done by removing the
bolts B. (fig 8.3).
Note: If the pivot is raised, it is suggested to
replace the back pan with a larger pan to
decrease the gap from the bottom of the backrest
