Off-board Charger/Programming Socket
Your DL-50 may have a 3-pin socket on the front which enables you to use an off-board battery charger. The socket
may also be used for reprogramming the controller by using a programmer, should this be necessary. Contact your
authorized Pride provider for more information.
Horn
Activates the horn.
9-pin Connector
This connects the DL-50 controller to the power chairs batteries, motors, and motor brakes.
3-pin Charger Inhibit Connector
This connects the DL-50 to the onboard battery charger. This connection provides the DL-50 with an inhibit that
disables it when the battery charger is on. During charging, the battery condition meter will flash briefly to indicate
that the inhibit is active. The charger inhibit connector is coded with colored dots. The dots are positioned so that
you align the flat side of the male connector with the flat side of the female connector before making the connection.
CAUTION! Failure to properly align the connectors can result in damage to the controller, the charger
harness, and the connectors.
Joystick Out Of Neutral At Power Up
Your power chair joystick is equipped with Out Of Neutral At Power Up (OONAPU). If you power up the system
and the joystick is not in the neutral (center) position, the battery gauge flashes rapidly in 2.5-second intervals. The
battery gauge will flash as long as the joystick is out of the neutral position. If the joystick remains out of the
neutral position for four seconds or more, then the battery gauge will display a fault. If this happens, then return the
joystick to the neutral position and power off the DL-50. The next time you power on the DL-50, the code should
be cleared.
NOTE: If this condition persists, contact your authorized Pride provider.
Thermal Rollback
The DL-50 electronic controller features a thermal rollback circuit. This circuit monitors the temperature of the
motors, the power module, and the master remote. In the event these components become excessively hot (above
122° F), the power module reduces the motor voltage. For every degree above 122° F, the power module reduces
the voltage by 5 volts. This reduces your speed and allows the components to cool down. When the temperature
returns to a safe level, your power chair will resume its normal speed.
Troubleshooting
In addition to indicating battery charge, the lights also provide diagnostic information when the DL-50 detects
problems with either the electrical system, or the DL-50 itself. These codes are displayed when all lights flash the
number of times given by the fault code. The following table identifies the individual fault codes. If you get one of
these codes, contact your authorized Pride provider.
