Base - Lower PCA board (LPCA)
The base Lower PCA ( LPCA
1
) receives machine control commands from the console and dir-
ectly 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 information to
the console.
The LPCA makes use of two main processors: the Master (also referred to interchangeably as
“Major”) and Slave (also as “Minor”).
COMM Communication Interface Cable
Active Status Light (ASL)
Active Status Light: similar to Treadmill ASL, except that operation has been changed for self-
powered machines. A separate microprocessor and software on the LPCA control the color
and flashing of the LED. A button near the light is used to wake up the entire system tem-
porarily to check its color, and to clear the status color if pressed long enough. Active Status
Light processor receives simple commands from the Console, see
" Active Status Light (ASL)"
on page 147 .
