Sleep Mode
The R-net Controller has a sleep mode feature. Sleep mode is a built-in circuit that automatically shuts off
the main power if the joystick is not moved in any direction for a period of time predetermined by controller
program. The battery condition meter lights on the keypad indicate sleep mode by blinking once every five
seconds. To restore power and continue, push the on/off button twice.
Thermal Rollback
The R-net Controller is equipped with a thermal rollback circuit. This circuit monitors the temperature of the
controller, which roughly translates to motor temperature. In the event that the R-net controller becomes
excessively hot, motor current (amperage) is reduced. For every degree above normal temperature, the
motor current limit is reduced proportionally. This reduces “power,” which could also reduce power chair
speed. Once the R-net Controller reaches its temperature limit, the current output is reduced to zero and
your power chair will stop. This allows the electrical components and motors to cool down. When the
temperature returns to a safe level, your power chair resumes its normal operation.
Fault Codes
The R-net Controller is designed with the user’s safety as the prime consideration. It incorporates many
sophisticated self-test features which search for potential problems at a rate of 100 times per second.
If the R-net detects a problem either in its own circuits or in the power chair’s electrical system, it may
decide to stop the power chair, depending on the severity of the problem. The R-net is designed to
maximize the user’s safety under all normal conditions. The following table identifies the individual fault
codes. Fault codes are displayed as a rapid flashing of the lights. If you encounter one of these fault codes
or experience any other problems with your power chair, turn your controller off and then on again. If the
problem persists, contact a Pride/Quantum Rehab Provider.
Flashing Lights Diagnosis and Solution
1 The batteries need charging or there is a bad connection to the batteries. Check the connections to
the batteries. If the connections are good, try charging the batteries.
2 The left motor has a bad connection. Check the left motor connection.
3 The left motor has a short circuit to another connection. Contact your Pride/Quantum Rehab Provider.
4 The right motor has a bad connection. Check right motor connection.
5 The right motor has a short circuit to another connection. Contact your Pride/Quantum Rehab
Provider.
6 The power chair is being inhibited. Contact your Pride/Quantum Rehab Provider.
7 A joystick fault is indicated. Make sure that the joystick is in the center
8 A controller system fault is indicated. Make sure that all connections are secure and the batteries
are fully charged.
9 The parking brakes have a bad connection. Check the parking brake motor connections. Make sure
the controller connections are secure.
10 An excessive voltage has been applied to the controller. This is usually caused by a poor battery
connection. Check the battery connections.
