SOLENOID VALVE IDENTIFICATION
Each hydraulic valve solenoid is assigned a solenoid number
used in Manitowoc Cranes training classes (see Table 3-6
).
The pin number corresponds to the control module
connector pin number, as represented in the electrical
schematics.
The control module information contained in each solenoid
or pin number is illustrated in Figure 3-11
. In this example,
for the swing brake release solenoid, the following
information is contained:
• Control module resides on CAN Bus C
• Control module index is 22
• Control module digital output is ODH3A-03
• Control module output signal is at pin 2 of connector
