DESCRIPTION

HPD/SRO Type

0–3

Determines whether the HPD/SRO feature will be active. One type of checks

HPD_SRO_Type

0–3

is available for material-handling vehicles, and two types for golf-style vehicles.

OptionBits1 [Bit 4]

If any of the HPD/SRO checks finds an input sequencing problem, an
HPD/Sequencing Fault (flash code 47) is set.

0

HPD/SRO feature is disabled.

1

HPD/SRO checks enabled for material-handling vehicle.

At KSI on, a one-time check of the inputs is made to verify

that the following inputs have been activated in the proper order:

KSI first, then interlock before either direction input or a throttle

input >25%.

Continuous check every time the interlock turns Off and the

sequencing delay time has expired (the sequencing delay timer

starts counting down when interlock switches off); a check is

made the next time interlock is applied to verify that interlock was

applied before either direction input or a throttle input >25%.

2

HPD/SRO checks enabled for golf-style vehicle.

At KSI on, a one-time check is made to verify the throttle

input <25%.

Continuous check when the vehicle is stationary (bit variable

Park_State_Speed_Control = On means stationary) to verify

the interlock and a direction switch were applied before throttle

input >25%. The order of the interlock and direction switch does

not matter. Once moving (Park_State_Speed_Control = Off),

directional switching (forward to reverse, or reverse to forward) is

allowed with throttle input >25%; i.e., no fault results.

3

HPD/SRO checks enabled for golf-style vehicle.

At KSI on, a one-time check is made to verify the throttle

input <25%.

Continuous check to verify the interlock and a direction

switch were applied before throttle input >25%. The order of the

interlock and direction switch does not matter. Type 3 differs from

Type 2 in that it only checks this condition when the vehicle is

stationary. With Type 3 the interlock and a direction switch must

always precede the throttle input regardless of vehicle speed.

Sequencing Delay

0.0–5.0 sec. Typically the sequencing delay feature allows the interlock switch to be cycled

Sequencing_Delay

0–312

within a set time (the defined sequencing delay), thus preventing inadvertent
activation of HPD/SRO. This feature is especially useful in applications where
the interlock switch may bounce or be momentarily cycled during operation.

VCL Throttle Enable

On/Off

When programmed On, the throttle processing with fault detection will operate

VCL_Throttle_Enable

On/Off

normally; however, the throttle command (see Figure 14, page 92) will require

VCL_Throttle_Enable_Bit0 [Bit 0]

VCL to define the connection between the OS_Throttle and VCL_Throttle
variables. This allows VCL flexibility and customization of throttle processing,
while still allowing Throttle_Type 1–4 with throttle fault detection.
