Chapter 4: Programming the Rhino2
4.4.6 Park Brake Management
4.4.6.1 Park Brake Testing
This parameter allows you to disable open-circuit testing on the park brake. Disabling open-
circuit testing does not disable short-circuit testing. Short-circuit park brake testing is ALWAYS
performed, even when the parameter is set to None.
Driving - The RHINO2 checks the park brake for open circuit and short circuit faults before
and during driving.
Pre-drive - The RHINO2 checks the park brake for open-circuit before driving, but not during
driving. Use this option when the test during driving is very noisy and/or incorrect
faults are generated. Short circuit faults are still checked pre-drive and during
driving.
None - The RHINO2 does not check the park brake for an open-circuit fault.
This option allows the RHINO2 to be used without an electric park brake. Short
circuit faults are still checked.
Warning:
For safety reasons, do not use 'None' if the scooter has an electric park brake.
4.4.6.2 Park Brake Neutral Delay
The Park Brake Neutral Delay parameter sets the delay between zero speed demand (after
the scooter has decelerated and stopped) and the moment that the park brakes are
engaged.
The correct value of this parameter is dependent on the mechanics of the park brake that is
used on the scooter. The delay must be longer for fast acting park brakes.
If the value of Park Brake Neutral Delay is set too high, there may be too much rollback when
stopping on a slope. If the value is set too low, the scooter may stop too abruptly.
