If the Programmer displays Unrecognized Error, this is probably because the Programmer software needs upgrading to include the Help Text for that Error Code. Please refer to the Programmer’s documentation for details of how to upgrade to the latest software.

Diagnostic Warning Diagnostics should only be conducted by electronic service professionals with in-depth knowledge of PG Drives Technology electronic controllers. An incorrect or badly effected repair could result in an unsafe set-up of a vehicle. PG Drives Technology accepts no liability for losses of any kind arising from an incorrect or badly effected repair. PG Drives Technology accept no liability for losses of any kind arising from unauthorised opening, adjustments or modifications to any component of a control system.

0A00: Control System in Sleep Mode Wheelchair Control Systems This condition is indicated by the TruCharge display "blinking on" once every 2.5 seconds. It is not a trip condition, but an indication that the control system has gone to sleep. To awake the system, switch off and on again. In the case of the VR2 the control system will turn off completely. The control system goes to sleep after a programmed period of time. If you want to adjust this time or remove the function altogether go to the Operation group. Scooter Controllers This condition is indicated by the Status Indicator "blinking on" once every 2.5 seconds. It is not a trip condition, but an indication that the controller has gone to sleep. To awake the system, switch off and on again. The controller goes to sleep after a programmed period of time. If you want to adjust this time or remove the function altogether go to the Operation group.

0300, 0810, 0814, 0815, 0816, 0817, 0E07, 0E08: Throttle Trip This occurs when the controller detects a fault in the throttle or the connections to it. Check the connections and the Throttle. If the trip is still present after the above checks have been made, then the controller may be defective. There are no serviceable parts in any of the PG Drives Technology controller. Consequently, any defective units must be returned to PG Drives Technology or a PG Drives Technology approved service organization for repair. Opening or making any unauthorized adjustments or modifications to a control system or its components will invalidate any warranty and may result in hazards to the vehicle user, and is strictly forbidden. WARNING PG Drives Technology accept no liability for losses of any kind arising from unauthorized opening, adjustments or modifications to a any component of a controller. EGIS

1320: Current Limit Active This occurs when the control system operates above the Current Limit Threshold for a period of time greater than the Current Limit Time. This has been designed to notify the Healthcare Technician that the control system has operated outside of its programmed range.

1330: Motor Stall Timeout If the throttle is deflected but the scooter cannot drive because: It is on a slope that is too steep, or It tries to climb up a curb that is too high, or It is trapped, then the maximum current (as set by the Current Foldback Threshold parameter) will flow through the motor continuously, because the motor is still trying to drive. Motor stalling can cause motor damage when the motor becomes too hot. To prevent motor damage, the after Motor Stall Timeout current will be cut to the motor and the brake engag
