SOLENOID VALVE IDENTIFICATION
Each hydraulic solenoid valve (HS) is assigned a number (#)
for troubleshooting. The wire number of each solenoid can
be found in the electrical schematics.
Each HS-# is determined as follow: the first number is the
universal node number and the second two numbers are the
digital output assigned to that solenoid on that node. For
example, HS-311 = Node 3, Digital Output 11 (DO11).
