Diagnostic Information
• Programming 101 – Dongle and DTT Refresher
• You can enter OBP using a key sequence from the JSM also.
– With the system off, hold both the ON/OFF and horn buttons.
– The system will beep, let go of the horn button but keep the ON/OFF
still depressed.
– Once the system beeps again, let go of the ON/OFF button and it will go
into OBP.
– This only works on an LCD joystick (Color or Monochrome).
• This also works with the R-Net - Omni by Holding On/Off and P
(Profile) button.
• Reminder: You can't only have one programming option active at a
time.
– DTT active = no connection to OBP
– OBP active = no connection via Dongle
– This is true for all combinations.

LED Diagnostics – R-Net EL Control
LED Control System Status Indication: The battery gauge and Maximum Speed/Profile
indicator show the status of the control System. With the help of this listing it is possible to
diagnose problems that may appear drastic at first, but may have a ver y simple and easy
to fix cause.
1.
Batter yGauge is Stead y: This indicates all is well
2.
Batter yGauge Flashes Slowly: The control s ystem is functioning correctly, but you
should charge the battery as soon as possible.
3.
Batter yGauge Steps up: The wheelchair batteries are being charged you will not be
able to drive until chair is disconnected from charger. Switched Power On and Off again.
4.
Batter yGauge Flashes Rapidly(even when joystick released): The control system
safety circuits have operated and the control system has been prevented from moving the
chair. This indicates a system trip – The R-Net has detected a problem somewhere in the
wheelchairs electrical system. Please follow below procedure:

5.
Speed Indicator Ripples Outwards From Center: In this instance the LEDS make a
ripple motion starting with the Middle LED and then stepping outwards on Both sides. The
Control System has detected that a new module has been added and is re-configuring.
Please allow for a few seconds for this to complete
6.
Speed Indicator LED’s 2 & 4 Flash: Then the control system requires a reboot. For
example, after a module re-configuration, the second and fourth speed indicator LED’s will
flash.

Diagnostic Text Definitions
Text Code May Not have number corresponding to Error
1. Joystick Center Error – 2F00 - Center Joystick
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. Ensure that the joystick is centered and power-up the control
system. If still not working could be internal Gimble or Joystick board itself.
2. Low Battery – 2C00 – Below Operational voltage
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. Full voltage should be 12.57 or higher per
battery lower than 9 volts per battery is designated as depleted or dead. 23.5 volts
will indicate a Single Segment on the display screen.
3. High Battery Error – 1600 - Battery Voltage Greatly Excessive
This occurs when voltage is over 35 volts – due usually to power on during charging
and a voltage spike.

4. M1 - Motor Error - 3B00 - Motor 1 Motor Fault
This occurs when the control system has detected Motor 1 has become
disconnected. Check wiring connections – motor resistance should be low resistance
of less than 1 ohm. A quick test is to exchange motor leads from M1 to M2 and see
if problem changes or still exists. If after connection and resistance checks are found
to be good – replace out control module. If motor fault changes to opposite side
check brushe s.
5. M2 – Motor Error – 3C00 - Motor 2 Motor Fault
This occurs when the control system has detected Motor 2 has become
disconnected. Check wiring connections – motor resistance should be low resistance
of less than 1 ohm. A quick test is to exchange motor leads from M2 to M1 and see
if problem changes or still exists. If after connection and resistance checks are found
to be good – replace out control module. If motor fault changes to opposite side
check brushe s.
6. M1 – Brake Error – 1505 - Brake Solenoid Fault Motor 1
This occurs when control does not see good resistance or connector to brake input
of motor control. Check brake resi stance and connection to control module. If all are
good then control module may need to be replaced.

This occurs when control does not see good resistance or connector to
brake input of motor control. Check brake resistance and connection to
control module. If all are good then control module may need to be
replaced.
8. Inhibit Active – 1E03 – 1E02 – 1E04 – 1E05 –
Last 2 Digits specify Module
This occurs when any of the Inhibit inputs are active and in a latched state.
The actual inhibits listed are referring to JSM - 03 - PM - 02 – ISM for 04
and 05. Cycle the power . Check all wiring and switches connected to
inhibits. This can cause lockout of module as in charging chair or limited
or no drive for the ISM seating module. No drive if connection to control is
not connected.

9. Joystick Calibration Error –
Joystick CAL error – Joystick - SID or Specialty
This occurs when Joystick or SID Calibration process has not been
successful or failure upon connection to Omni. Enter OBP and attempt
calibration. If still present may have bad Gimble internal - contact
Technical Service for parts or replacement. Joystick Calibration is
shown on next page.
10. Over Current (acts) – Actuator 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 actuator motor,
cables or connections or endstop switch. Check the movement of the
actuator is not obstructed. If all had been checked and still issue it may be
a defective SM or ISM.

Joystick Calibration in OBP
• This procedure is for LCD – Monochrome , Color or
Omni R-Net Units for Proper Calibration
– To begin the procedure you must first enter OBP mode and go to the System
branch. Select the listing of Joystick calibration option.
– The procedure is automatic, simply follow the on-screen instructions. Values for
both the Forward/Reverse and Left/Right SID axes will be displayed. Alongside
each value will be an X or a √ symbol:
•
X - Indicates the axis value is outside of the permitted calibration range for
the particular direction
• √ - Indicates the axis value is within the permitted calibration value for the
particular direction.
– Simply deflect the Device in the instructed direction until both values are with the
permitted range indicated by advancing automatically to next direction.
– A large check will be displayed on screen, for a short period of time to indicate
succe ss! The screen will then return to the System Menu.

11. Overtemp (acts) Actuator over Temperature Range
This occurs when control system detects that the SM or ISM’s actuator circuitry has
become too hot. The control system will cease to drive the actuator motor in
question. Allow the SM or ISM to cool. If the SM or ISM is frequently overheating
check the condition of the actuator motors – re sistance and connections to them. If
still occurring may need replacement of the components mentioned above. Detail on
ISM shown on Next 3 Pages.
12. DIME Error - Distinguishing ID Memory Error
This occurs when the control system detects and identification conflict between 2
modules in the system. If a new module has been added disconnect and recycle
power – if no trip present reconnect new module if trip reappears due to new unit. If
no new module connected – disconnect from Battery Power for 30 seconds and
reconnect power is fault still occurs contact Technical Service to replace out module.

Intelligent Seating & Lights Module (ISLM) –
Connection Details - 108216
•
Inhibit Connections
The ISM contains the inhibit 4 and 5 connections. These connections can be used to limit speed, inhibit
driv e and/or inhibit actuator channels.
•
Lighting Connections
Each lighting output is rated at 21W maximum. The output is self -protecting against wiring and bulb faults
and will shut-off if the max power rating is exceeded. Likewise, if the output becomes too hot it will shut-off
to prevent damage to itself
•
ISLM
Each actuator channel is rate at 15A maximum, although only 12A is available when the channel is
programmed to 100% speed. If currents of greater than 12A are required, the programmed speeds f or that
channel must reduced. The level of reduction is dependent upon the electrical characteristics of the actuator
motor, so an empirical process to establish the lev el of the reduction is required. If the wheelchair is f itted
with solid mechanical end-stops at the end of the actuator trav el, it is not necessary to f it limit switches as
the ISLM can detect when the actuator motor has stopped and will cutoff the power to it.
