High Speed Switch and Anti-Tie Down

Vehicles with a High Speed Switch configured will normally drive at the Cutback 1 Speed, but
will allow the maximum speed of the vehicle to increase to 100% in Reverse or the Cutback 2
Speed in Forward when the High Speed Switch is active. This is usually used for a Walkie type
vehicle with a ride on platform where Reverse (Power unit forward, Forks trailing) is the normal
driving direction.
This function has two modes, Normal and Momentary. Normal mode only activates this feature so
long as the switch is active, Momentary mode activates this feature when the switch is active, and
keeps the High Speed Operation active after the switch is released. High Speed Mode is
configurable via the Calibrator.

There are two separate options for High Speed Operation:
Normal (Unlatched). High Speed Operation is only active when the switch is active.
Momentary (Latched). High Speed Operation is active as soon as the switch is made active
and remains active after the switch is released until any of the Anti-Tie Down conditions
become true.
High Speed Operation will be activated when the following conditions are TRUE:
Normal mode:
The High Speed Switch is active, and,
Anti-Tie Down is not inhibiting the feature. Anti-Tie Down is used to prevent High Speed
operation under conditions where the operator may not be expecting it.
Momentary mode:
The High Speed Switch has been active at least once to initiate the function, and,
Anti-Tie Down is not inhibiting the feature.
The speed demand in the Reverse direction (Power Unit Forward) is limited to the Cutback Speed
1 configuration item, if High Speed Operation is not active.
The speed demand in the Forward direction (Forks Forward) is limited to one of the following:
The lower of the Cutback Speed 1 configuration item or the Cutback Speed 2 configuration
item, if High Speed Operation is not active.
The Cutback Speed 2 configuration item, if High Speed Operation is active.
