Section 1 - Batteries
Description:
The batteries are used to power the chair and need to be
maintained to have full potential and use of product. Please
use specified batteries and follow all charging
recommendations. Please use charger provided by
manufacturer – neglect of this will void warranties.
Safety
If mishandled batteries can be dangerous and hazardous.
1. All mobility batteries whether Gel or 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 a possible explosion.
This is why proper handling is mandatory at all times.
2. Battery explosion - this is the result of too low an
acid/electrolyte level in the battery, which allows high
concentrations of hydrogen to built up. This is possible
with all batteries if improper charging or battery failure
occurs. But not common in gel/sealed batteries.
3. Keep sparks and flames away from batteries
5
4. Burns – dropping a wrench or screwdriver across battery
terminals results in sparks and arcing and intense heat.
Improper wiring and assembly may short the battery the
wiring and produce an electrical fire.
5. Pollution – Batteries should be disposed at a reliable battery
recycler. Improper disposal of batteries damage the
environment.

As battery discharges, the sulfate from the electrolyte
forms on the plates. As battery recharges, the sulfate is
driven back into the electrolyte.

2. Check to insure the strap is fastened tightly around case
As shown in photos below:
Depressing Metal allows you to pull tighter on strapping
3. Check to make sure connector locks and plastic clips are
Engaged which ensures connector is locked see photos
Below:

4. Batteries use a slide out battery tray and operation to open
is done by positive forward pressure on the back and pulling
of handle at same time shown below:
This allows release through
2 different tabs which secure it from releasing through heavy
vibration or terrain seen below:
This pulls enough for

Troubleshooting Batteries
1. Check for good voltage at Module input charger
port. Should read between 23.5 and 25.8 volts for proper
operation. Less than 23.5 volts will give a low battery
Indicator (2 Bar flash).
2. If no voltage at port go to cable that inputs voltage to
Control found on battery box connector shown earlier.
Once again verify voltage and check for popped circuit
Breaker. Reset Circuit breaker.
3. If still no power go directly to individual batteries across
+ and – posts to see at least 12.2 to 13 volts (fully charged).
4. The 3 tests above will verify voltage in what is known as an
unloaded state. The next test is to insure batteries last under
load. This can be done a number of ways. 2 ways of
checking are listed below:
a) The load test across the + and – terminals of battery - make
sure battery is in full charged state. Hook up load tester
and draw 100 amp load across for 10 seconds.
b) The chair has a free wheel release where the motor and
gearbox can be run un-loaded – this still draws 3 -4 amps
across the load. Hold joystick or input device for 1 minute
If after release in a minutes time it drops more than a volt
Change batteries – if it drops between .6 and 1 volt it has a
Cell that is weak and batteries will no stay fully charged
It is recommended to change batteries. If the voltage after
a minutes time drop less that .1 volt but not greater than
0.5 volts the batteries are in good shape.
Code 2C00 – indicates Low Battery - 1 Bar Flashing

Chargers
Introduction: The battery charger is another essential part of the
Power Chair for the batteries need to be fully charged daily for
heavy users. It is strongly recommended of any technician to
make sure they have a spare charger that is working well and/or
a good set of batteries.
1. Lester Off-Board 8 amp Charger - The Lester Off Board
charger part number BATC8LS – is a Transformer Driven 8
amp charger that has been working in this industry for over 17
years. It have an easy to operate switch that turns on the charger
and has 2 LED’s to indicate charge rate and faults.
The chargers operation is when AC and DC voltage are
available (Note: 18 volts minimum DC) the Green Light flashes
to indicate charge rate. A slow flash indicates the batteries need
a charge and it is output 8 amps as the charging continues when
the voltage approaches the bulk charge rate it starts flashing the
Green LED rapidly indicating 2 amp rate until is sees a change
of less than 500 mV and then turns Solid Green to indicate full
charge cycle.
The table below depicts operation of Green and Red LED
operation and fault modes.

2. Troubleshooting Chargers - When troubleshooting electronic
equipment there is equipment necessary for checking and
evaluation. The very first is a Multi-meter used for checking
Resistance (continuity) – AC voltage from the Wall Plug – D.C.
voltage from the batteries and Current the flow of the charger.
The second is a load tester needed to evaluate (normally at 100
amps for 10 seconds) the batteries capacity to hold a charge rate.
The other two items recommended but not a necessity is a
good set of batteries and/ or another known good charger.
Troubleshooting Tips
1. Check for battery voltage and polarity at chair’s charger
input.
The voltage needs to be at least 18 volts for the charger
to turn on.
2. Check for continuity between cable (DC output and inside)
this is performed with a Multimeter
on the setting of resistance and with each of the
connector points test the wiring from one end to the
other which is inside the charger plug and charger.
3. Check for A.C. voltage. The wall outlet in North America
should give a reading between 110 and 120 volts A.C.
4. Check for possible blown fuse. As a protection to the
charger and chair components this fuse will go if it
attains close to 15 amps of current - it will not operate
charging of chair until replaced.

Motors
Intro: The motor is an essential part of any Power Chair and
needs to be looked at annually or when an error occurs which
point to one of 3 parts that make up Motor Assemblies. The
motor assembly consists of the motor – brake – and gearbox.
The Xperience and Xplore both use the same style motor
and there are 2 varieties of motors to choose from. The next
section shows parts of the Motor – Removal – and Diagnostics
for trouble-shooting the motor.

Motor Assembly - Removal
Xperience
1. Take the 4 - 5/8” bolts from the Wheel Assembly shown in
photo below:
2. Remove connector from motor control - access through front
of chair box shown below:
Note: no tools necessary for step above
Shows access and removal of connector for ease of removal –
disconnect yellow communication connector as well
19
3. Remove shroud and release assembly - 10 mm and Phillips
screwdriver required as well as pliers and 7/16” wrench
Remove shroud bracket assembly
using a 7/16” open end and ratchet.
4. Remove cotter pin using long nose pliers to firmly remove
5. Disassemble the release mechanism further using a Phillips
screwdriver to remove 3 screws holding attaching plate
20
Note: Pictures below show parts after removal and removal
of Plastic restraining clip. This step is necessary for both
motor and motor assembly removal.
6. Next step in removing complete assembly is to remove with
a ratchet or open wrench the quantity 5 - 10mm head bolts.
Note: remove rubber stopper prior to removing back bolt
21
If the plate is not removed you will need an open end wrench
to remove the corner bolt near plate holder.
7.
Finally to remove complete Gearbox and Motor the
Chair needs to be moved on its side as shown.
This allows to move frame downward to remove assembly
22
Xplore Motor Assembly - removal
1. Follow details found on page 17 - removal of Drive Wheel
and removal of motor connector from control.
2. This gives access to the motor and shroud assembly
Remove the 2 Phillips Screw with No. 2 Phillips Screwdriver
3. You now have access to the Motor Gearbox 5 - 10 millimeter
head bolts – remove cotter pin first prior to the bolts with a
pair of Long Nose pliers as mentioned on page 18 of manual
23
Place where Cotter pin should be removed
Removal of 5 bolts using ratchet with 10 mm socket
Unlike the Xperience the Xplorer Motor assembly can be
removed if the bolts and cotter pin are removed no need to lay
chair on its side.
Motor only on both chairs:
To remove only the motor a 3/16" allen key socket is needed
and then remove the cotter pin from the holder on the frame as
well as removing connector from control.
24
Troubleshooting Motors
1. Testing the motors you will have various means to do this
by. The first way is if the motor has shut down and this is
verifying what Diagnostic Code you have there are 2 main
codes for left and right motor and 2 main codes for the
brake and solenoid. They are as follows:
3B00 – for the M1 connection open – control does not see
proper connection or resistance to Motor 1. Left Code for
rear wheel drive units and right code(3C00) for Mid- wheel
drive. (This is in reference to the Motor mounted on the left)
3C00 – for the M2 connection open – control does not see
proper connection or resistance to Motor 2. Right Code for
rear wheel drive units and left code(3B00) for Mid- wheel
drive. (This is in reference to the Motor mounted on the right)
1505- for the Right Brake open – control does not see good
Brake resistance – two cases: normally open – close to
0 ohms or shorted - ultra high resistance.
1506 - for the Left Brake open – control does not see good
Brake resistance – two cases: normally open – close to
0 ohms or shorted - ultra high resistance.
2. The check is very simple as shown on page 16 - check the
the small connector brake and large connector for motor.
15 – 16 ohms
0 – 2 ohms
25
3. The Motor may have a high resistance reading and this could
be due to one or two or more brushes that are damaged.
To extract, use a Large Straight edge screwdriver that
matches to the brush holder. This eliminates stripping and
basically ruining the entry of the brush housing.
Once extracted check the brush for spring wear and length of
Carbon material – it should be no shorter than 1//2 inch in
length and brushes should be wearing smoothly on
Commutator.

Shoulder Bolt Adjustment
The shoulder bolt is a key component of
the suspension assembly on both
the Quickie X series.
Understanding the proper adjustment
will help optimize the performance of
the power base.
There is 3 basic adjustment adjustments
to be performed with this type of
fastener;
1. Reduce the compression (to increase the
tolerance).
2. Increase the compression (to reduce the
tolerance).
3. Reduce the amount of play in a pivot point (to
compensate for wear of the bolt itself and/or
“Oil-lite” bushing).
35
The shoulder bolt is designed to offer a consistent length
from the shoulder (A) to the head (B). This allows for a
precise and consistent fit independently of the amount of
torque applied to the nut which prevents for an assembly to
be over or under tightened.
36
Reducing Compression
1. Reducing the compression of a pivot point is
necessary when it can’t move smoothly without
excessive resistance. Such a situation could prevent
the 6 wheels to remain in contact with the floor.
Special attention should be paid to:
- The pivot point of the Front swing arm
- The pivot point connecting the front swing arm to
the rear arm
- The pivot points of the links (connecting the rear
arm to the base)
Reducing the compression of a pivot point
- Process;
• Adding shim(s) (Part #: AMY E00260) on
the threaded part of the bolt will extend it’s
overall length which allows for a looser fit if
needed.
37
Increasing Compression
Increasing the compression of a pivot point is necessary
when too much play can be felt. This could cause excessive
camber of the swing-arms. Attention should also be paid to:
- The pivot point of the Front swing arm
- The pivot point connecting the front swing arm to
the rear arm
- The pivot points of the links (connecting the rear
arm to the base)
Increasing the compression of a pivot point
- Process;
• Adding shim(s) (part #: AMY E00281) at
the thickest part of the stem will reduce the
overall length of the bolt which allows for a
tighter fit.
38
Reducing the Play
Reducing the amount of play may become necessary after a
certain period of time when the “Oil-Lites” bushings wear
down or compress and deflect.
- When the inner hole gets deformed into an oval shape;
The “Oil-Lite” bushing provides more play to the pivot
point that may cause excessive camber of the swing
arm. This situation can be resolved with the
replacement of the worn-down components. In order to
insure proper fit, it is recommended to always replace
both the fastener and the “Oil-lite” bushings at the same
time on any of the pivot points. The replacement must
be performed with respect to proper compression
adjustments previously indicated.

This joystick has a Green On-Off switch with Red horn and top display gives indication
of both battery capacity and Diagnostic Codes. The center indicators are 5 individual
yellow LED lights that indicate either Speed (if module is set to “0” profile) or
individual lights indicating separate drive profiles up to 5. The operation of those
indicators is accomplished by pressing the right Speed/Drive select to increase or the
left Speed/Drive select to decrease the speed or drive. The Actuator or Seating buttons
indicate via a RED LED that it is active and a Forward and Reverse action to operate
the actuator. The 4-pin connector connects to a communication 4-pin connector that
connects back to the Motor Control.
The VR2 has 2 other models available – a unit without actuator - D50677 - and another

R-Net EL – Electronics Programming
AMY-D50612 complete as seen above
AMY-EC-0084 complete with
Wires and manual
The Dongle Kit can be used for Computer only The Diagnostic Test tool can be
used the same as on PM120 controls
R-NET PM120 – Control System
The AMY-D50612 - kit can be used as in the EL programming or you can use the Dongle
connected to the System to do On-Board programming of the System without
connecting to a computer. The OBP Dealer Dongle is part number AMY-D50109
57
R-net On-Board Programming
On-Board Programming (OBP) uses the graphics LCD on the R-net Joystick
Module to provide a clear display of multiple profiles, and allows for easy
navigation and adjustment of the screens, using intuitive combinations of
joystick movements and button presses. Access to OBP can be made secure
via a keycode or a hardware key (dongle).
A diagram is shown below how it connects to the system:

Turn off the control system.
Insert the R-net Dongle along the communication cables in the system configuration
Note: Dongle part number AMY- D50109 or Kit Part # AMY-D50112
58

Turn on the control system
After initialization press the Mode key until the OBP screen is reached. See following
diagram:
Note: Mode 8 is the Mode for OBP – very important not to shut off or you will not have
function of OBP.
Navigating the OBP Screens
While in OBP deflecting the joystick to the left, while the parameter title is highlighted,
will display an elongated version of the parameter name.
There are two basic forms of display screen – one which shows global parameters and
one which shows parameters which are profile dependent, i.e. can have different values in
each of the drive profiles.
Example of a global parameter screen:
Forward joystick deflections will select the parameter
above.
Reverse joystick deflections will select the parameter
below.
Left joystick deflections will take you to the previous
screen.
Right joystick deflections will have no effect.
59
Example of a profiled parameter screen:
Forward joystick deflections will select the parameter above.
Reverse joystick deflections will select the parameter below.
The first left joystick deflections will display the parameter name
in full.
The second left joystick deflection will take you to the previous
screen.
Right joystick deflections will select the parameter to the right, if
available.
Making an Adjustment
Once the parameter for adjustment has been selected, the Speed buttons can be used to make
adjustments.
Decrease
Speed Up/Down Buttons
Increase
To ensure all new values are stored correctly, exit OBP mode with a series of left hand joystick
deflections. A push of the Mode button will put you back to Drive mode and save as well.

Example: To prevent a user gaining control from the Profile that is used by the Attendant
control. The system if set up as below.
Profiles 1 to 4 are set for any type of user Input Device
Profile 8 is set for Attendant control
The Select parameter in Profiles 1 to 4 does not include Profile 8, meaning the user
cannot select Attendant control.
The Select parameter in Profile 8 includes all Profiles, meaning the Attendant device can
always select its own Profile.
The Grab parameter in Profiles 1 to 4 does not include Profile 8, meaning the user can
move between Profiles 1 to 4, but cannot gain control from Profile 8 (the Attendant
Profile)
The Grab parameter in Profile 8 includes all Profiles, meaning the Attendant can gain
control from any other Profile.

Seating Section
The parts and picture above show the position of where the
brackets will be mounted on seating without Power Options.
On the next page shows more details to this followed by a few
pages describing what is necessary to achieve different Seat to
floor heights.
The first part to learn is about the Fixation Settings
75
Please look at picture below:
You will see there are 4 different settings for front and rear which
If you add to together equal 8 arrangement but is actually 4²
The first group of setups will be for 19” seat depth for either
Xplore or Xperience.
76
Once you go above 17.50 inches you have more variety of angles
From 0 to 6 degrees on 18” seat to floor
77
Even further setting of seat angle as we go to 18.75 for 0 to 9
degrees.
The next height is 19.375 and once again offers the 0 to 9 degrees
of changes in seat settings.
78
The seat setting can be adjusted even further to 20 – 21.25 and
achieve angles up to 12 and 15 degree’s.
All of these settings are done with the combination of Drive wheel
types of 14” and the arrangement of front caster sizes of 6 – 8 or 9
inch depending on chair type.
Note: Remember the Xperience has a choice of 6 or 8 inch casters
and the Xplore has a choice of 8 or 9 inch casters.

SAC – Single Actuator Control
“New” unit as of Oct. 01-2009
Figure 1 - SAC box
Figure 2 - SAC box internal
The SAC box is a single actuator control which
has all channels tied together so whether
hooking up a Tilt – Recline – Left Leg – Right
Leg – and or Elevate – it will see this.
Figure 2 shows the internal of the SAC box
and the RED dip Switches are normally set to
OFF as depicted in the wiring diagrams of the
parts manual.
The upper left corner
of the picture depicts the jumpers internal for the
setup of what type of system is used – inside
plate will eventually be changed but for now we
follow for our chairs the same as MK6 for jumper
settings depicted on Figure 3 next page.
83

DAC – Dual Actuator Control
Figure 4
Figure 4 - depicting the Dual Actuator control the input
lines as mentioned on the preceding page this time
has one line dedicated to Tilt – and then ties the other
lines together for the other actuator to be chosen –
recline tilt – lift etc.
One of the things nice about these new control
devices is that you can stay with the same wiring if
you are not making any changes to the seating.
Example if you have Tilt already and decided to
change from SAC to DAC it is a matter of just
switching the boxes and this is the idea of the new
Electronics to make it easy to change out.
2 diagrams of the wiring for SAC and DAC
85
You will notice 3 things on this diagram a Kit # is
always on left corner - showing the complete parts for
a SAC to work with Tilt – the wiring showing a
complete connection with depiction to actuator and
inhibits – and finally the top right corner showing the
DIP switch Settings.
86
You will see on this one we are using the same
cable D00235 but we are using the cable control to
the Recline actuator.
MAC – Multi Actuator Control
Showing limit adaptor D00146 & 145 - Above is Dip Switch selector
87
The multi actuator control is just that it allows up to 5
actuators to work on. It has an internal Dip Switch that
allows variation of operation of Seating.
Included below from Parts Manual is the
The above gives the kit # in left corner wiring diagram

Omni Installation
The Omni can be used with many different types of SID’s and then in various
modes of operation, driving, latched driving, seat adjustment etc. The Omni Must
be configured to meet individual requirements of the user. Below is a suggested
installation and set-up sequence:
1. Assess user’s needs and select relevant SID.
2. Install the Omni onto the powerchair.
3. Install the SID onto the powerchair.
4. Program the Omni to match the SID.
5. Program the Omni to suit the user.
6. Program the R-Net driving characteristics to suit the user.
When installing SID onto chair if usage is for only operation one device
it is recommended to connect to Port and make sure all connections are
tight – route and secure all cables and tubes in such away as to prevent
damage by crushing, cutting or snagging.
User Switch is recommended for safety and ease of use for customer – it
is recommended to set to Normally Open. If switch is disconnected as
additional safety a warning of User Switch disconnect will come up on
screen – preventing drive of chair. In programming of Switch Detect we
also have a setting of Limp which allows slow driving with a visual of
Limp on screen. The option of off is there as well but not recommended.
OBP – (On-Board Programming) -Through the OMNI
This is performed using the Omni’s own display and front panel buttons.
From the Omni, all system OBP parameters can be adjusted: for
example, Speeds and Accelerations.
To enter into this mode the R-Net Dongle is required as described in
Programming section – for connections – after connected turn on control
system and using the mode button to step to OBP mode. It is very
important as the dealer to make sure Mode 8 is never turned off for that
is what allows access to OBP mode.
Note: While the Dongle remains attached, the mode button can be used
to access all system modes and to return back to OBP mode.
The other 2 options of programming will be through the Hand Held
known as DTT or PC Programming via software and Cable.
107
Program the Omni to Match SID
The Omni is compatible with Six Types of SID
1. Joystick
2. Five Switch
3. Three Axis Proportional
4. Three Axis Switch
5. Sip & Puff and User Switch
6. Single switch scanner
This can all be found when programming under the heading of SID
The 6 types are shown above how they are displayed under
Port 1 or Port 2.

The exact cause will depend on the type of wheelchair
you have,
one possibility is the battery charger is connected.
A joystick fault is indicated. Make sure that the joystick is in the center
position before switching on the control system
A control system fault is indicated. Make sure that all connections
are secure.
The parking brakes have a bad connection. Check the parking brake
and motor connections. Make sure the control system connections are
secure.
An excessive voltage has been applied to the control system. This is
usually caused by a poor battery connection. Check the battery
connections.
A communication fault is indicated. Make sure that joystick cable is
securely connected and not damaged.
An Actuator trip is indicated. If more than one actuator is fitted, check
which actuator is not working correctly. Check the actuator wiring.

Note: This will be referenced for the EL LED joystick only.
112
The battery needs charging or there is a bad connection to the battery.
Check the connections to the battery. If the connections are good, try
charging the battery.
Troubleshooting Batteries
1. Check for good voltage at Module input charger
port. Should read between 23.5 and 25.8 volts for proper
operation. Less than 23.5 volts will give a low battery
Indicator (2 Bar flash).
2. If no voltage at port go to cable that inputs voltage to
Control found on battery box connector shown earlier.
Once again verify voltage and check for popped circuit
Breaker. Reset Circuit breaker.
3. If still no power go directly to individual batteries across
+ and – posts to see at least 12.2 to 13 volts (fully charged).
4. The 3 tests above will verify voltage in what is known as an
unloaded state. The next test is to insure batteries last under
load. This can be done a number of ways. 2 ways of
checking are listed below:
a) The load test across the + and – terminals of battery - make
sure battery is in full charged state. Hook up load tester
and draw 100 amp load across for 10 seconds.
b) The chair has a free wheel release where the motor and
gearbox can be run un-loaded – this still draws 3 -4 amps
across the load. Hold joystick or input device for 1 minute
If after release in a minutes time it drops more than a volt
Change batteries – if it drops between .6 and 1 volt it has a
Cell that is weak and batteries will no stay fully charged
It is recommended to change batteries. If the voltage after
a minutes time drop less that .1 volt but not greater than
0.5 volts the batteries are in good shape.
Code 2C00 – indicates Low Battery - 1 Bar Flashing
113
The left hand motor* has a bad connection. Check the connections to the
left hand motor.
The left hand motor* has a short circuit to a battery connection. Contact your

1 Joystick Error
The most common cause of this trip is if the joystick is deflected away from center before and
during the time the control system is switched on. The joystick displaced screen will be displayed
for 5 seconds, if the joystick is not released within that time then a trip is registered. Although a
trip screen is not displayed the system log will show the trip and numbers of occurrences.

Ensure that the joystick is centered and power-up the control system.
If the trip is still present then the joystick or Joystick Module may be defective.
115
2 Low Battery
This occurs when the control system detects that the battery voltage has fallen below
16V.

Check the condition of the batteries and the connections to the control system.
If the trip is still present after the batteries and connections have been checked, then the
Power Module may be defective.
3 High Battery Voltage
This occurs when the control system detects that the battery voltage has risen above 35V.
The most common reasons for this are overcharging of the battery or bad connections
between the control system and the batteries.

Check the condition of the batteries and the connections to the control system.
If the trip is still present after the batteries and connections have been checked, then the Power
Module may be defective.
4 & 5 Brake Error
This occurs when the control system detects a problem in the solenoid brakes or the
connections to them.
1505 -
M1 Brake Error
1506 -
M2 Brake Error

Check the solenoid brakes, cables and connections to the control system.
If the trip is still present after the above checks have been made, then the Power Module may be
defective
6 & 7 Motor Error
This occurs when the control system detects that a motor has become disconnected.
3B00 - M1 Motor Error - Refer to section 2.3 for connection details
3C00 - M2 Motor Error - Refer to section 2.3 for connection details

Check the motors, cables and connections to the control system.
If the trip is still present after the above checks have been made, then the Power Module may be
defective.
8 Inhibit Active
This occurs when any of the Inhibit inputs are active and in a latched state.
116
The actual inhibit that is active is indicated by the last 2 digits in the Trip Code. The code
is in Hex.
1E01 - For Inhibit 1
1E09 - For Inhibit 9
1E0A - For Inhibit 10

Cycle the power. This will drop out of Latched Mode that might clear the trip.

Check all wiring and switches connected to the indicated Inhibits.
If the trip is still present after the above checks have been made, then the ISM may be defective.
9 Joystick Calibration Error
This occurs when the Joystick Calibration process has not been successful.

Enter OBP and attempt calibration.
If the trip is still present after the above has been attempted, then the Joystick Module may be
defective. The internal Joystick Gimble may be faulty and part can be replaced.
10 Latched Timeout
This occurs when the control system detects that the Latched Timeout programmed time
has been exceeded. For example, the Input Device (Joystick, Head Array, Sip and Puff,
etc.) has not been operated frequently enough.
The trip is a notification of why the control system has dropped out of Latched Mode.

Cycle the power.

Initiate Latched Mode.
If the trip is still present after the above checks have been made, then the Input Device may be
defective.
11 Over-current
This occurs when the control system detects an excessive amount of current in an
Actuator Channel.
This may be due to a faulty end stop switch, actuator motor, cables or connections.

Check the movement of the actuator is not obstructed.

Check the end stop switches (if fitted) are terminating the power to the actuator
motor.
If the trip is still present after the above checks have been made, then the ISM may be defective.
12 Overtemp (acts)
This occurs when the control system detects that the ISM’s actuator circuitry has become too hot.
The control system will cease drive to the actuator motor in question.

Allow the ISM to cool.
117

If the ISM is frequently overheating check the condition of the actuator motors and
the connections to them. If the trip persists contact your service agent.
13 Bad Settings
This occurs when the control system detects incorrect or invalid program settings.

Check all parameter settings and re-program the control system using the R-net
PC Programmer.

Make a note of the current parameter settings and then reset the control system
to default settings.

Re-program the required settings in small groups, cycling the power after each
group to see if the trip occurs.
If the trip is still present after the above checks have been made, then the PM may be defective.
14 DIME Error
This occurs when the control system detects an identification conflict between two modules in
the system.
If a new module has been introduced:

Disconnect the new module and cycle the power.

If no trip is present connect the new module to the system and cycle the power.

If the trip reappears then the new module must be the cause of the problem.
If there has been no additions:

Disconnect one module at a time and cycle the power.
If the trip is still present after the above checks have been made, contact your service agent.
15 Memory Error
This is a non-specific memory error that could be caused by any of the modules within
the system.

Check all cables and connections.

Cycle the power.
If the trip is still present and the system contains 3rd party Modules:

Disconnect all the non-PGDT modules and cycle the power.
If this has cleared the trip:

Connect each 3rd party module in turn, cycling the power each time.

If the trip reappears after one of the power cycles then the last module to have
been added to the system must be defective.
If the trip is still present after the above checks have been made, then the PM may be defective.
118
16 PM Memory Error
This is a specific Power Module based trip.

Check all cables and connections.

Using the R-net PC Programmer, re-program the control system.
This should be done with either the most current specific program file for the wheelchair
or the manufacturers original programming file. If the trip is still present after the above
checks have been made, then the PM may be defective
17 Bad Cable
This occurs when the control system detects a fault in the wiring in the communication
cables between any of the modules.

Check all cables and connections for continuity.

If there is any visible damage to cables, replace and cycle power.

Disconnect one cable from the system at a time cycling the power after each
disconnection.
If the trip is still present after the above checks have been made, then the PM may be
defective.
18 Module Error
This occurs when the control system detects a trip within a specific module. The module
will be identified on the diagnostics screen as described in section 2.

Check all cables and connections.

Cycle the power.
If the trip is still present after the above checks have been made, then the module
identified may be defective.
19 System Error
This occurs when the system detects a trip that cannot be attributed to a specific module.

Check all cables and connections.

Cycle the power.
If the trip is still present and the system contains 3rd party Modules:

Disconnect all the none-PGDT modules and cycle the power.
If this has cleared the trip:

Connect each 3rd party module in turn, cycling the power each time.

If the trip reappears after one of the power cycles then the last module to have been
added to the system must be defective.
If the trip is still present after the above checks have been made, then the PGDT control system
may be defective.
119
20 SID Disconnected
The Omni has detected that the Specialty Input Device (SID) has become disconnected.

Check all cables and connectors between the Omni and the SID.
If the error persists:

Check that the setting of the parameter, 9-Way Detect, is appropriate for the SID that
is being used. For example, if the SID has no detect-link, then this parameter should
be set to Off.
If the trip is still present after the above checks have been made, then the Input Device may be
defective. Contact your service agent.
