4.5. Ramp Start
This feature provides full SCR torque to restart a vehicle on
an incline. The memory for this function is the directional
switch. When stopping on an incline, the directional switch
must be left in its original or neutral position to allow the
control to assure full power when restarted.
4.6. Full Power Transition
This built-in feature provides smooth transition from SCR to
1A bypass. This is accomplished by the SCR continuing to
pulse until the 1A contactor power tips close.
4.7. Control Acceleration and 1A Time
This feature allows for adjustment of the rate of time it takes
for the control to accelerate to 96% applied battery voltage to
the motor on hard acceleration. The 1A contactor will
automatically close. Two seconds after the controlled
acceleration stops and the accelerator input is less than .5
volts or less than 50 ohms. C/A is adjusted by function 3 from
.1 to 22 seconds.
4.8. 1A Current Drop Out
This adjustable feature can be set to open the 1A contactor if
the traction motor is subject to excessive currents. The
dropout is adjustable with function 6 of the handset. Once the
control has dropped out the 1A contactor due to excess
current, the directional or accelerator switch must be returned
to neutral to unlock the dropout circuit to allow the control to
pick up the 1A contactor again. Using this feature will reduce
the 1A contactor tip life, thus it should be used only where
needed to protect the motor.
