Life Fitness Model 9500 Series Cross-Trainers
THEORY OF OPERATION
The electronics system of the CT-9500 Series Cross-Trainers, is made up of three distinct modules, the Power
Entry Module, the Display Console, and the Power Control Board.
120 volts AC enters the Power Entry Module. It passes through a transformer and is converted to 14 volts AC.
The 14 volts AC is applied to the Power Control Board at connector J4, pins 1 and 2. The voltage passes through a
bridge rectifier, BR1 and is converted to an unregulated positive DC voltage. This unregulated voltage will vary
from 11 volts DC to 18 volts DC depending on the wall supply and load. This voltage can be measured by placing
the positive probe of your DVM on Positive Test Point at BR1 and the negative probe on the negative Test Point at
BR1.
The other voltage developed on the Power Control Board is a regulated positive 8 volts DC. The regulated 8 volts
DC is developed by transistor (Q2) . This voltage can be measured by placing the positive probe of your DVM on
the collector(case) of Q2 and the negative probe on the anode of D1.
This 8 volts DC is supplied to the Console at connector J1, pin 4 and is used to power the LED’s. The 8 volts DC is
also used as a supply voltage for the positive 5 volt DC regulator (U1) on the Console board, which is VCC for the
Microprocessor. The Keypad entry (user’s input), Life Pulse (9500HR only), Telemetry, and the Stop Switch
functions are all processed by the Microprocessor.
The Console, by pulse width modulating the field control line, sends a signal to the Power Control Board at J1, pin
1. The Power Control Board switches the field current to the Alternator, through Q1. This field current along with
the energy supplied by the user is sent to the Load Resistors. This places resistance on the rotation, thus providing
the load sensation felt by the user.
The Alternator also provides the source for the RPM sensor circuit. The AC tap output on the Alternator enters the
Power Control Board at J2, pin 3. This AC voltage is wave conditioned and outputted at connector J1, pin 2 to the
Console connector P2, pin 6. Where it is processed and displayed by the Console.
