NOTE: We recommend that the first few times you operate your power chair, you set the speed to the
slowest setting until you become familiar with your new power chair.
Actuator Key and Actuator Lights (for optional equipment)
Actuator keys and actuator lights are used for optional equipment such as power elevating seats or power elevating
leg rests. For specific operation of the actuator keys and actuator lights, contact your authorised Pride provider.
Horn Key
The horn key activates the horn.
Off-board Charger/Programming Socket
You may use an off-board charger to charge the power chair batteries through the 3-pin socket located on the front
of the VSI. See figure 5a. If you use an off-board charger, the charger current should not exceed 12 amps. Contact
your authorised Pride provider for more information.
CAUTION! Only chargers with Neutrik NC3MX plugs should be connected to the off-board
charger/programming socket. See your authorised Pride provider for more information.
NOTE: The socket may also be used for reprogramming the VSI. Contact your authorised Pride provider
for more information.
Controller Connector
This connects the VSI to the power chair’s batteries, motors, and motor brakes.
3-pin Charger Inhibit Connector
This connects the VSI to the onboard battery charger. This connection provides an inhibit that disables the VSI
when the battery charger is on. 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 VSI, the
charger, and the connectors.
Thermal Rollback
The VSI controller is equipped with a thermal rollback circuit. The circuit monitors the temperature of the controller,
which roughly translates to motor temperature. In the event that the VSI controller becomes excessively hot
(above 60° C/140° F), motor current (amperage) is reduced. For every degree above 60° C/140° F, the motor
current limit is reduced by .55 amps until the VSI controller reaches 70° C/158° F, at which time the current output
is reduced to zero. This reduces your power chair’s “power,” which could also reduce your power chair’s speed,
and allows the electrical components and motors to cool down. When the temperature returns to a safe level, your
power chair resumes its normal operation.
