PARAMETER RANGE 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.
