Theory of Operation
About
The treadmill is comprised of two basic system blocks, the console provides the user interface
and operational controls. It contains the Upper PCA board which sends the control input
information to the base. The base contains and uses the Lower PCA board to execute
received operational commands. The Lower PCA returns status and error code information to
the Upper PCA for display and diagnostics.
Consoles
Basic operation
This section will explain basic operation and functions that apply to all models of consoles. For
specific details about a particular model of console (Standard, P10, P20, P30, P80), refer to
the applicable console service manual.
The supported console models include the P10, P20, P30, P80, and P82 models.
Controls
All consoles provide user input (keypad functions), user display (LED display / user feedback),
automated control (heart rate program, interval program) and service software routines (tests,
settings, and information).
The keypad functions can vary between different console models, however the basic functions
that all consoles have include the Quick Start, Incline (up or down) and Speed (up or down)
functions.
Features
Different console models provide a different set of user features but the basic operation and
servicing software is the dame.
The service software functions exactly the same for all console models. Each console uses the
same service software standard access codes to access the Hardware Validation Tests, Club
Parameter settings, or Information Display modes, see
"Standard Service Software" on
.
The service software also utilizes the same Standard Error Codes in all console models, see
"Standard Error Codes" on page 70
Console to Base Interface
The console processor (upper PCA board "UPCA") provides user input, user display and auto-
mated control to the system. The console processor communicates with the base processor
