(1) Positive 5.1 V power supply (PS5). Receives +32 V input from the
power module. Converts the +32 V input to a stabilized +5.1 V used for control
logic on other circuit boards in the machine. PS5 contains a voltage sensor that
will, after turning off the machine, initiate a reset to the hardware channel and
positioning computer circuits. A green LED on the board, when lit, indicates normal
operation. Voltage output can be measured between the blue and red test receptacles.
A potentiometer on the board allows for adjustments.
(2) Positive 24 V power supply (PS24). Receives the same +32 V from the
power module as PS5. Converts the +32 V input to a stabilized +24 V used for control
board, when lit, indicates normal operation. Voltage output can be measured between
the blue and red test receptacles. A potentiometer on the board allows for
adjustments. PS24 also has a fuse (located on the board) to protect its output.
