Ramp start (anti-rollback)
The ramp start feature allows the vehicle to be started with a higher plug current
limit to prevent rolling downhill. Ramp start increases the plug current limit for
the selected direction only. When the opposite direction is selected, ramp start
will be canceled and a 3-step sequence must be followed to re-activate it:
STEP
STEP
STEP
Once the vehicle is operating in ramp start mode, it will continue to do so until
the opposite direction is selected for more than one second. The new direction
then becomes the decision direction, and the 3-step ramp start sequence is
required to regain the ramp start current limit level.
The handheld programmer can be used to adjust the maximum ramp start
current limit value. The instantaneous ramp start current limit when the brake is
first released depends on throttle position and increases to the maximum pro-
grammed value as the throttle is increased.
Reset
Almost all faults require a cycling of the KSI or brake/seat switch input to reset
the controller and enable operation; see "Fault recovery" for exceptions.
Sequencing delay
Sequencing delay allows the brake/seat switch to be momentarily opened within
a set time (the sequencing delay), thus preventing inadvertent activation of HPD
or SRO. This feature is useful in applications where the brake/seat switch may
bounce or be momentarily cycled during operation. The delay can be set with the
handheld programmer from 0 to 3 seconds, where 0 corresponds to no delay.
Speed settings
The maximum speed setting defines the upper-limit speed as a percentage of
PWM output at full throttle. The maximum speed settings in Mode 1 and in
Mode 2 are independently adjustable via the handheld programmer.
The maximum creep speed setting (see Creep speed) and the maximum
emergency reverse speed setting (see Emergency reverse) are also adjustable via the
handheld programmer.
