ANTI-TIEDOwN

The anti-tiedown feature prevents operators from taping or "tying down" the
mode select switches in order to operate permanently in Mode 2 or Mode 4.
On startup, when the interlock switch is first closed, the anti-tiedown feature
checks which operational mode is selected. If the mode select switches are re-
questing Mode 2 or Mode 4, the controller will ignore the request and default
to Mode 1 or Mode 3 respectively. The controller will remain in Mode 1 or
Mode 3 until the Mode Select 1 switch is released and reactivated.
Anti-tiedown is primarily used in walkie applications. It can be pro-
grammed "On" or "Off."
SEQUENCING DLy
The sequencing delay feature allows the interlock switch to be cycled within
a set time (the sequencing delay), in order to prevent inadvertent activation of
HPD or SRO. This feature is useful in applications where the interlock switch
may bounce or be momentarily cycled during operation. The sequencing delay
parameter can be set from 0 to 3 seconds, in increments of 0.1 second, with 0
corresponding to no delay.
PEDAL INTR
The pedal interlock parameter can be programmed as "On" or "Off." When
"On," it requires that the pedal switch input (Pin 8) be active (pulled to B+)
before the controller will supply power to the motor. This feature is useful in
systems that use a seat or foot switch to guarantee operator presence for vehicle
operation. Alternatively, a switch connected to the brake pedal can be configured
