[PCF]
Determines the type of HPD (High Pedal Disable) / SRO (Static Return to Off)
protection. One type of checks is available for material-handling vehicles, and
two types for golf-style vehicles.
If any of the HPD/SRO checks nds an input sequencing problem, an HPD/
Sequencing Fault (ash code 47) is set.
0. HPD/SRO feature is disabled.
1. HPD/SRO enabled for material-handling vehicles.
HPD: If throttle input is received before interlock input.
SRO: If direction input is received before interlock input.
The HPD/SRO check is made when the interlock input changes from
Off to On. If the throttle input >25% or a direction input is On, an HPD/
Sequencing Fault is set.
The HPD/Sequencing Fault is cleared by returning the throttle input to
<25% or the direction inputs to Off.
2. Golf-style HPD that allows direction reversal while driving.
HPD: Throttle input received before interlock, or throttle input received
before direction input while vehicle is stationary.
SRO: None.
The HPD check is made when the interlock input or direction inputs
are Off and the vehicle is stationary. If the throttle input >25%, an HPD/
Sequencing Fault is set.
No SRO check is made with this type, so the order of the interlock and
direction inputs does not matter.
The HPD/Sequencing Fault is cleared by returning the throttle input to
<25% or the direction inputs to Off.
3. Golf-style HPD that prevents direction reversal while driving.
HPD: If throttle input is received before interlock or direction input.
SRO: None.
HPD check is made when the interlock input or direction inputs are Off.
If the throttle input >25%, an HPD/Sequencing Fault is set. The check is
done regardless of vehicle speed, so reversing direction with throttle input
>25% will result in a fault.
No SRO check is made with this type, so the order of the interlock and
direction inputs does not matter.
The HPD/Sequencing Fault is cleared by returning the throttle input to
<25% or the direction inputs to Off.
Sequencing Delay

Typically the sequencing delay feature allows the interlock switch to be cycled
within a set time (the dened 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.

When programmed On, the throttle processing with fault detection will
operate normally; however, the throttle command will require VCL to dene
the connection between the OS_Throttle and VCL_Throttle variables. This
allows VCL exibility and customization of throttle processing, while still
allowing Throttle_Type 1–4 with throttle fault detection. Figure 18 (page 112)
illustrates these throttle chains.
