DYNAMIC DL-50 CONTROLLER
The DL-50 electronic controller is an integral electronic controller. All of the electronics necessary to operate the
power chair are contained in one module. See figure 28.
The DL-50 consists of:
1. joystick
2. on/off push key
3. battery condition meter
4. speed control
5. off-board charger/programming socket
6. 9-pin connector
7. 3-pin charger inhibit connector
8. horn
Typically, the DL-50 is mounted to one of the armrests and is
connected to the motors, batteries, and the onboard charger
at the electronics tray.
Joystick
The joystick controls the direction and speed of your power chair. When you move the joystick from the netural
(center) position, the electromagnetic brakes release and allow your power chair to move. The further you push the
joystick from its neutral position, the faster your power chair moves. When you release the joystick and allow it to
return to the neutral position, you engage the electromagnetic brakes. This causes your power chair to decelerate
and come to a complete stop.

WARNING! If your power chair begins to move in an unexpected manner, immediately release the joystick.
Unless the joystick is damaged, this action should stop your power chair.
On/Off Key
This is an on/off key located in front of the joystick which turns the DL-50 on and off.
WARNING! Unless faced with an emergency situation, do not use the on/off push button to stop the chair.
This will cause the power chair to stop abruptly.
WARNING! Always turn the power off when you are stationary to prevent unexpected movement.
Battery Condition Meter
The battery condition meter is located behind the joystick. This is a six-segment, three-color illuminated display
that indicates if the DL50 is turned on and also gives the battery status, the DL-50 status, and the electrical system
status. All six red lights lit represents a full state-of-charge and a single red light lit represents lowest state-of-
charge. A low state-of-charge warning is represented by the left-most light flashing on and off.
NOTE: Check your battery condition meter regularly and charge the batteries before they are completely discharged.
Speed Control
Sets the maximum speed of the power chair: clockwise to increase, counterclockwise to decrease.
NOTE: We recommend that the first few times you operate your power chair, you turn the speed control to the
slowest setting until you become familiar with your new power chair.
