manually disengage (see page 28 of the user guide). If there are any
application errors by the vehicle or the user that cause one of the
disengage conditions to be met, then eDriveTC will disengage. For
example: the operator occasionally bumps the steering wheel
activating the steering switch, or the vehicle is operating near the
ground speed cutoff and occasionally exceeds or goes below it. If
the Auto-Engage feature is turned on and parameters to engage are
met then eDriveTC will automatically reengage after one of these
events.
5. My Auto-Engage feature is turned on but the eDriveTC will not
engage after setting the AB line.
This likely is happening because one of the eDriveTC disengage
criteria are being met. Each time one the eDriveTC is disengaged
then the system is reset and must go back through the auto-engage
routine. See pages 27 to 30 in the eDriveTC User Guide for
eDriveTC auto-disengage, manual disengage and auto-engage
criteria.
6. Why are the lights on the valve interface cable connectors flashing?
When eDriveTC is engaged, the hydraulic valve is pulsed at a high
rate. Each time a pulse is sent to turn left or right, one of the LED’s
on the valve interface cable will illuminate.
7. How do I know that I have a reliable electric power source for the
eDriveTC system?
The eDriveTC system needs to be connected to a solid 12 volt
automotive power supply. Any intermittent or low voltage may
cause poor auto steering performance. Typically a direct
connection to a 12 volt battery is the best way to ensure reliable
power. If in doubt about the voltage of your power supply, use a
volt-meter to measure the voltage of the connection during a
typical field operation.
