5.4. Troubleshooting Chart Using the

Handset

Fault Test When Disable Controller When Recover When

BB circuit check (BB = Belly Button)

Coil open/shorted driver Continuous after brake release Circuit found open Brake released

Entering and in neutral, before allowing PWM out, after brake released Immediate Cycle Brake S10

Contactor driver overcurrent Continuously while contactor being driven Immediate Cycle Brake S10

Overvoltage Continuous after brake released Immediate Cycle Brake S10 Power supply out of range Once upon activating S17 and continuous after brake release Immediate Cycle Brake S10

M-fault PWM output (0+) percent to 85 percent. After brake release and not in emergency reverse Immediate Cycle Brake S10

M-circuit check Brake released Immediate Cycle Brake S10

Start-up checks Once upon activating S17 RAM & EEPROM failure only Cycle S17

Throttle fault Continuous after brake released Set throttle input to zero, decel output PWM to zero Condition clears

Under voltage, Severe Once upon activating S17 and continuous after brake release Immediate Cycle Brake S10

Current sensor fault Continuous while PWM on Immediate Cycle Brake S10 Vds over current Continuous while PWM on Immediate Cycle Brake S10 Watchdog, Ext. Continuous while S17 on Immediate Cycle Brake S10 Watchdog, Int. Continuous while S17 on Immediate Cycle Brake S10

Welded contactor Continuous while brake released & no contactor driven Immediate Cycle Brake S10

Parameter block check Initiating serial communication Never - disable serial interface Reinitiating serial interface

The following are indicated and handled similarly:

Fault Test When Action Recover When

Emergency reverse BB pressed forces E/R E/R action (see text) BB re-applied or brake released

HPD Depends on type, see text Disable PWM output throttle cycled Thermal cutback Brake released See text See text

Undervoltage Continuous while S17 on Immediate Condition clears
