Drive Control Input (DCI)
NOTE: Wheelchairs equipped with DCI have seating options (i.e. elevate and tilt).
The DCI allows the wheelchair mode to depend on the resistance of the DCI “Loop”:
• Inhibit - prevents the wheelchair from driving, typically when the wheelchair is being
charged, or when the seat is tilted.
• Slow - limits the drive speed to a predetermined value, typically when the seat is
raised.
To determine the mode, an appropriate resistance must be placed across the DCI input
pin (I) and the DCI Battery Negative (-) pin. Depending on the resistance value, the
controller will inhibit, slow, and/or swivel driving. Resistors used must be 5% tolerance
resistors.
