Active low inhibit: P2- pin 6 0V ± 0.5V to inhibit
5V ± 0.5V to drive
Active high inhibit: P2- pin 6 0V ± 0.5V to drive
5V ± 0.5V to inhibit
If the voltages are correct and the trip is still present, then the controller may be defective.
Refer to section 5.
3.7 Trip Type 7 - Throttle Trip
This occurs if the controller detects a trip in the throttle potentiometer or the connections
to it.
The following voltage measurements can be made for either a potentiometer input
throttle or voltage input throttle. 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 to BATT –ve: nominal 4.75V (P2 - pin 1)
Wiper to BATT –ve: nominal 2.5V (P2 - pin 3)
Lo Ref to BATT –ve:nominal 0.25V (P2 - pin 2)
Single-ended throttle: Hi Ref to BATT –ve: nominal 4.75V (P2 - pin 1)
*Wiper to BATT –ve: nominal 0.25V (P2 - pin 3)
Lo Ref to BATT –ve:nominal 0.25V
(P2 - pin 3)
* 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 or the connections
to it. Check these connections and the solenoid brake. On a correctly functioning
system, the following voltage levels should be present.
P2 pins 13 to 14: 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.
The above voltage measurements should be carried out with
the vehicle’s drive wheels raised above the ground. Read the
vehicle manufacturer’s instructions regarding the jacking up
of the vehicle.
