GENERAL TROUBLESHOOTING GUIDELINES
This troubleshooting section is organized into five basic sections: Basic Electrical
Theory, the Power Control Board, the Systematic Electrical Troubleshooting, Con-
sole Diagnostic Tests, and Systematic Mechanical Troubleshooting. Perform the
tests in exactly the same order as written. Refer to the “Parts Removal and Re-
placement” section of this manual for any assembly and disassembly instruc-
tions. To order a replacement part or to get help with the troubleshooting pro-
cess, contact our Customer Service Department at (800) 331-3578. International
customers should contact their local distributor or call (425) 823-1825.
BASIC ELECTRICAL THEORY
The power supply takes 110 VAC from the outlet and converts it to 12 VDC for
the machine to use. The 12 VDC is then routed up the power supply cable to the
power control board, where it is dispersed to perform various duties. The impor-
tant electrical paths to remember are the 12 VDC path to the alternator, and the
12 VDC path that travels up to the console via the main cable. The power from
the main cable turns on the console. Inside the console, a smaller power control
board takes the 12 VDC and redirects 5 VDC back down to the lower power con-
trol board where it is used to run items that require lower voltages, such as the
brake motor. Meanwhile, the voltage routed to the alternator is used to generate
a field current. This current is sent back to the power control board, where it is
stored and utilized by the console to “pulse” the load resistor. Depending on the
input from the user, the console varies the duty cycle of the load resistor. The
duty cycle refers to the length of time that the console allows the resistor to col-
lect and dissipate electrical energy. The more it absorbs and disperses the harder
the workout for the machine user.
THE POWER CONTROL BOARD
The power control board on the 5600 ESS is equipped with a 10-segment Light
Emitting Diode (LED) bar graph to used as a troubleshooting tool. These 10 LEDs
are designated from right to left. Nine of the ten LEDs will be illuminated while
the machine is at rest and the brake is engaged. The tenth LED will never be illu-
minated. The LED bar graph can help in giving you direction toward troubleshoot-
ing and repairing the 5600 ESS.
