System Measurements Mode
The System Measurements Mode lets you measure critical voltages in the battery/alternator circuits, under both idle
and operating conditions.
To enter the System Measurements Mode:
• On entering the Service Settings Mode, press the "8" key while in "service settings". "Measurements" will dis-
play in the upper information display.
• Press the "Scroll" key to view the system measurements available.
• Press the "Enter" key to exit the System Measurements Mode and return to the Service Settings Mode.
Once the unit is in the System Measurements Mode, use the [Arrow Keys] to select the desired system measure-
ment.
The following voltage measurements may be taken while in the System Measurements Mode:
MEASUREMENT DESCRIPTION
Battery Voltage Measures and displays battery output voltage while the unit is idle. Output voltage for a
normal battery should range between
6.2-7.7
volts.
•
Output voltage below
6.2
volts indicates a low battery charge or a damaged battery.
•
Output voltage above 7.7 volts indicates a fault in the Load Control Board.
Alternator Voltage Measures and displays alternator output voltage while the unit is in use. To check the al-
ternator output voltage:
•
Pedal the unit at a speed above
1.5
miles-per-hour.
•
Alternator output voltage should range between
11.5-13.5
volts. Voltages outside this
range indicate a fault in the Load Control Board.
Wall Power Measures and displays the voltage delivered to the unit from an optional external wall-
powered power pack while the unit is idle. An acceptable power pack voltage will range
between
11.0-18.0 voltage. The power pack should be replaced if the voltage is outside
this range.
Load Voltage
Measures and displays the voltage generated across the workout loading resistor while the
unit is in use. To measure the load voltage:
•
Pedal the unit at a speed above 1.5 miles-per-hour.
•
Load voltage should range between
1.0-10.0
volts. Voltages outside this range indi-
cate a fault in the Load Control Board. A lower voltage indicates a high resistance
which is normal.
