Electrical System Overview
Power-up sequence
When the user begins pedaling at speed greater than minimum, 40 strides per minute (spm)
the lower circuit (LPCA
1
) powers up and delivers power to the console, and all systems ini-
tialize.
The LPCA will remain powered ON using battery power until the pedal speed drops below the
minimum 40 spm which then starts the pending shutdown process.
Banner default state
When the user begins pedaling at speed greater than minimum, 40 strides per minute the
lower circuit (LPCA) powers up and delivers power to the console, and all systems initialize.
The LPCA will remain on under battery power until the pedal speed drops below the minimum,
at which time the system enters Pending Shutdown state.
l Exercise program is the manual program.
l Goal type is time.
l Goal value is the club time limit.
l All other exercise program parameters revert to default values appropriate to the spe-
cific exercise program.
l Weight is 170 pounds or 77 kilograms.
l Age, gender, target heart rate and fitness score are unknown.
l Units, language, and optional metric are read from EEPROM
2
, as set by Owner Set-
tings. Factory defaults for these are U.S., English, and no optional metric.
When the machine returns to Banner state after an exercise session ends, the following accu-
mulated session data is stored in memory until the system goes through the Initialization state,
or until the next user performs data entry.
1
Lower printed circuit assembly; generally this refers to the lower board. On treadmills, this is
the motor controller unit (MCU), and on self-powered units, it is the main board in the lower
section.
2
Electrically erasable programmable read-only memory and is a type of non-volatile memory.
