CHAPTER 8 – DIAGNOSTICS
1 INTRODUCTION
The primary objective of this chapter is to assist service personnel in diagnosing the likely cause of an Omni2 trip. It is
important to realize that even though the Omni2 itself may be signaling a trip, it may not be defective. This is because the R-
net control system is able to detect problems in other electrical components (motors, batteries, solenoid brakes, etc.) or,
more importantly, the wiring to them. When a control system has detected a trip, a system trip is indicated.
This chapter covers the diagnostic process for the Omni2 trip display analysis, accessing the system log using OBP, trip
identification and possible restorative guidelines.
WARNING (HP, IN)
Diagnostics should only be conducted by healthcare professionals with in-depth knowledge of PG Drives Technology
electronic control systems. An incorrect or badly effected repair could result in an unsafe set-up of a powerchair. Curtiss-
Wright accept no liability for losses of any kind arising from an incorrect or badly effected repair.
1.1 DIAGNOSTIC PROCEDURE
To diagnose a trip please follow this procedure:

Read and note the Trip Text displayed, the Identified Module and the Trip Code. Refer to section 2.

Switch off the control system.

Make sure that all connectors on the listed Module and the powerchair are mated securely. Check the condition of
the battery.

Find the definition of the Trip Text, and take the required action. Refer to section 3.

Switch on the control system again and try to drive the powerchair. If the safety circuits operate again, switch off and
do not try to use the powerchair.
Contact your service agent.
2 DIAGNOSTIC SCREENS
2.1 CURRENT DIAGNOSTIC SCREEN
When the control system safety circuits have operated and the control system has been prevented from moving the
powerchair, a diagnostics screen will be displayed.
This indicates a system trip, i.e. the R-net has detected a problem somewhere in the powerchair’s electrical system.
