The motor driver CCA monitors the power of all the valve motors for problems. If there is an
under-voltage or over-current problem on any one motor, it sends a valve fault bit to the control
CCA. Normal operation is a “1” and a fault is “0.” This fault is logged in the STS fault screen.
Valve CCA and Assembly
With the valve direction selected and the valve enabled, the +24 V DC switched is connected to the
valve motor to rotate the valve body. The valve CCA has three position sensors and three LEDs per
valve, for a total of nine position sensors and nine LEDs. There are three measured positions:
return, open, or collect. All the LEDs are continuously on and shine on the valve body housing.
There is a window in the valve body housing, and as the valve rotates the LED light shines through
this window and is detected by one of three position sensors. This detection creates a position bit
“0” for that specific position. The other two positions create a position bit “1” because the LED
light is blocked from reaching the sensor. When all three positions create a “1,” the position of the
valve is unknown. The position sensor bit is read by control and safety every 10 ms. This code is
also in the dlog file labeled as “valve position.” See the Troubleshooting chapter for more detail on
dlogs.
