Published 06-24-16, Control # 241-01
numbers that are on (active) in the bank are shaded black.
Use Table 3-10
and Table 3-11 to identify the crane
components associated with the identifiers for the
corresponding bank.
Example 1: If the number displayed in Bank 3 of screen D2
is 41, go to row number 41 in Table 3-12
. The boxes for
identifiers 1, 8, and 32 are shaded black in this row,
indicating that the corresponding inputs are active. Find the
component description for the identifiers in Table 3-11
, Bank
3. The inputs for High Speed Travel (Identifier 1), Drum 1
Brake (Identifier 8) and Low Air Pressure (Identifier 32) are
active.
Example 2: You want to know if the controller output for the
drum 2 clutch is on. In Table 3-10
you will find drum 2 Clutch
in Bank 1 (Identifier 64). Look up the current number for
Bank 1 in screen D1 (for example 152). Then go to the
corresponding row number (152) in Table 3-12
. Identifier 64
box is not shaded black in this row, indicating that the
controller output to the rear drum clutch is off.
All numbers in screen D1 and the pump/motor command
values in screens Drum, Swing, and Track represent
controller commands to the corresponding output devices
only. The state of a certain output port on the controller may
not necessarily correspond to the actual state of the
associated crane component (brake valve, clutch valve, or
other components), since the connection between the
controller and the component may be faulty due to loose
connections, corroded terminals, broken wiring, or
improperly operating components.
