Console - Upper PCA board (UPCA)
The console provides the user interface operational control inputs, the metric indicator
information, and the console-to-base communication interface. The console Upper PCA
1
board (UPCA
2
) sends the input control commands to the base Lower PCA
3
board
(LPCA
4
). The console also receives error code data from the base which is used to main-
tain the Error Log service menu. The console also controls and sends the ASL
5
status state
(based on the received error codes) to the base.
The LPCA makes use of two main processors: the Master (also referred to interchangeably
as “Major”) and Slave (also as “Minor”).
Base - Lower PCA board (LPCA)
The base Lower PCA
6
(LPCA
7
) receives machine control commands from the console and
directly executes the commands to control the braking, lift operation, and power ON/OFF.
The LPCA also monitors error conditions and sends the detected error event code inform-
ation to the console.
The LPCA makes use of two main processors: the Master (also referred to interchangeably
as “Major”) and Slave (also as “Minor”).
1
Upper printed circuit assembly; generally refers to the console.

Upper PCA board
3
Lower Printed Circuit Assembly board; also refered to as the Lower PCA or simply as the
lower board. On treadmills, it is the console to base function interface and the motor con-
troller unit (MCU). On self-powered units, it is the lower PCA console to base function inter-
face.

Lower Printed Circuit Assembly board; also refered to as the Lower PCA or simply as the
lower board. On treadmills, it is the console to base function interface and the motor con-
troller unit (MCU). On self-powered units, it is the lower PCA console to base function inter-
face.
5
Active Status Light: Service and maintenance status light.
6
Printed circuit assembly, generally referred to as either an upper PCA or lower PCA.
7
Lower Printed Circuit Assembly board; also refered to as the Lower PCA or simply as the
lower board. On treadmills, it is the console to base function interface and the motor con-
troller unit (MCU). On self-powered units, it is the lower PCA console to base function inter-
face.
