CPU board, part number C01410
The CPU Board is a six inch by six inch circuit board that contains the main processor
and program memory. It has total control over the smart tyer and can communicate with
an external terminal using the serial port connector on the front edge of the board. The
CPU Board is attached to the Amplifier Board with four mounting screws. Signal
connections between these two boards are made through the seventy-two pin connector
J2. The CPU Board has a seven-segment LED display that can display machine status
one character at a time. See Chapter 9 for specific details on this display. The CPU board
is considered a replacement unit. The proprietary software used to control the Smart Tyer
was developed by Burford
®
Corp. and cannot be altered in the field.
Amplifier board part number 611464
The AMP Board is a ten and one half inch by eleven inch circuit board that is controlled
by the CPU Board through the seventy-two pin connector J1. The Amplifier Board
contains the decoder electronics for the motor encoders as well as the pre-drivers and
motor drivers for each of the four axes. This board converts sensor and encoder signals
to five volt logic and relays them to the CPU board. Connections to motor power and the
motors are made at the edge of this board. Each motor output is fused individually to
protect the board from a shorted output. The AMP board also contains two relays, which
are described in pg.166.
