3.7 Trip Type 7 - Throttle Trip
This occurs if the controller detects a trip in the throttle potentiometer or the connections
to it.
Specific trip codes relate to different scenarios and these are detailed below.
Trip Code 0814: Throttle High Reference (pin 12) Disconnected.
Trip Code 0815: Throttle Low Reference (pin 5) Disconnected or Short Circuit
between Throttle High and Low References (Pins 12 & 5) or
Throttle Potentiometer is Incorrect Value.
Trip Code 0816: Short Circuit between Throttle Wiper and Throttle High Reference
(Pins 7 & 12)
Trip Code 0817: Short Circuit between Throttle Wiper and Throttle Low Reference
(Pins 7 & 5)
Trip Code 1D02: A Throttle Parameter setting has been adjusted. Restart controller
to clear the trip.
Check that the throttle is in the rest position and any speed limiting pots or buttons are
set to maximum speed. The nominal voltage levels should be as follows:
Wig-wag throttle: Hi Ref(pin 12) to BATT-ve nominal 4.75V
Wiper(pin 7) to BATT-ve nominal 2.5V
Lo Ref(pin 5) to BATT-ve nominal 0.25V
Single-ended throttle: Hi Ref(pin 12) to BATT-ve nominal 4.75V
*Wiper(pin 7) to BATT-ve nominal 0.25V
Lo Ref(pin 5) to BATT-ve nominal 0.25V
* If the 10 k Ω ISO Test resistor is used with single ended throttle, the nominal value at
Wiper is 0.188V
If the throttle input is functioning correctly and the trip is still present, then the controller
may be defective. Refer to section 5.
3.8 Trip Type 8 - Possible Controller Trip
This occurs when the controller detects a trip within itself. The controller must be assumed
defective and repaired by an authorized person. Refer to section 5.
3.9 Trip Type 9 - Solenoid Brake Trip
This occurs when the controller detects a trip in the solenoid brake, the connections to
it or when the Freewheel lever is disengaged. Check these connections, the solenoid
brake and the Freewheel Lever. On a correctly functioning system, the following voltage
levels should be present.
Brake + to Brake-: 0V ± 0.5V, when the throttle is at rest.
Battery voltage ± 1V, when the throttle is away from
rest.
If the voltages are correct and the trip is still present, then the controller may be defective.
Refer to section 5.
