About the Compass Sport Service Guide
This service guide provides you with the information necessary to troubleshoot the Golden Technologies
Compass Sport equipped with the Dynamic LiNX controller. The troubleshooting scenarios in this manual
consist of procedures that enable you to systematically trace and correct faults in the system.
Before troubleshooting, check the following:
•Make sure that the circuit breaker is reset.
•Visually check terminals for corrosion. Check wires for missing insulation.
•Make sure that the batteries are fully charged and in good working order. When possible, keep sets of
known good batteries of various ratings in your shop at all times. The Compass Sport uses 35AH (U1)
batteries. Problems that surface during troubleshooting are often due to the fact that the batteries are not
fully charged or can not hold their charge.
•Make sure that the electrical connections are secure. Unplug the connectors and make sure all of the
pins are seated properly. Push the pins back into the connector housing if necessary. Make sure that the
battery terminals are tight.
If you get to a point during troubleshooting where you cannot continue, call tech support at
800-624-6374.

The battery gauge will indicate the system is being charged by cycling between a
left-to-right chase sequence and then display the approximate battery charge state at
the end of the chase sequence.
Driving is prevented (inhibited) while the system is being charged.
The system does not have to be powered up when charging the battery, however, if it is
not powered up, then the battery gauge will not display the charging state/chase sequence.
The following indicates what the gauge will display for any given state.
High voltage warning
A high voltage warning is indicated by all LEDs on, and the green LEDs flashing. This occurs
when the battery voltage level has risen above the high voltage warning set-point.
Low voltage warning
A low voltage warning is indicated with the left-most LED flashing. This occurs when the
battery voltage level has dropped below its low voltage warning set-point. Charge the batteries immediately.

Troubleshooting Guide for the LiNX Power System
Step 1: Battery voltage is always the first thing to check.
A. Check the battery voltage at the XLR battery charger port located on the side of the controller See figure 8.
Set voltmeter to the 50 VDC scale.
Place the meter leads into the two outside pins of the battery charger port.
Meter should read approximately 25 VDC.
B. If the voltage is below 25 VDC:
Recharge the batteries for 8 hours.
Check wiring for any visible damage and make sure all the cables are connected properly.
Make sure that the pins are seated in the connectors properly and the fuses are good.
C. If the voltage is 20 VDC or less:
The battery charger may not recognize a low voltage and thus will not charge the batteries.
Boost charge the batteries to bring the voltage up to a level that the charger will see, then plug the battery
charger into the charger port and charge for 8 hours.
If the batteries will not charge, replace both batteries.
D. If the voltage is dropping too quickly, perform a load test on the batteries using a load tester. If you do not
have access to a load tester, you can load test by performing the follow steps.
Place the meter leads into the outside pins of the battery charger port.
Sit in the power chair and drive it.
After an initial drop, the voltage should hold steady at approximately 24VDC or higher when driving with a
load on the chair.
If the voltage continues to drop while driving, replace BOTH batteries.

Drive Inhibit
Drive inhibit mode is indicated by the battery gauge with a right-to-left light sequence.
The light sequence starts with the green LED on the right-hand side, and one-by-one, each LED will switch on
and then off. When the sequence completes at the left-most red LED, it begins again at the right-hand side.
The light sequence continues until the error condition has been cleared.
OONAPU
OONAPU (“Out of Neutral At Power Up”) is a safety feature that prevents accidental of the wheelchair, either
when powering up, or when the wheelchair comes out of an inhibit state.
If the LiNX LE System is turned on (or comes out of an inhibit state) while the joystick is not in the centre
position, an OONAPU warning is displayed. During an OONAPU warning, the battery gauge LEDs will flash
continually to alert the user, and the chair will not drive. If the joystick is returned to the centre position within
five seconds, the warning will clear and the wheelchair will drive normally.
However, if the joystick remains out of neutral for longer than five seconds, an OONAPU error will occur; the
error is displayed by the Status indicator flashing red, and the chair will not drive. To clear the error, return the
joystick to the neutral position and power the unit off and then on again.
