Calibration Diagnostics
TABLE 2. Calibration Diagnostic Issues
Booms and center section
will not raise/lower properly
through the Raven OS
manual controls.
Proportional/blocker coil
connections from the
AutoBoom harness cable
are incorrect on the
AutoBoom valve.
Check the connections on the AutoBoom valve to
ensure the harness cable connections are connected
to the correct ports.
Hydraulic connections to
the AutoBoom hydraulic
valve are reversed.
Trace the left cylinder (LC) and right cylinder (RC)
hydraulic lines connected to the AutoBoom valve and
switch the hose connections as necessary.
Trace the left cylinder return (LF CYL RTN) and right
cylinder return (RT CYL RTN) hydraulic lines
connected to the AutoBoom valve and switch the
hose connections as necessary.
Electrical connections are
reversed.
Check and switch the left and right electrical
connections (e.g. proportional, blocker, and pressure
transducer) connections as necessary.
Improper high current
voltage supplied to the
AutoBoom node or blown
fuse
Check the electrical connection and AutoBoom
harness fuses.
Center sense/control
cables are improperly
connected.
Check the center rack section control cabling
(connections to center control valve(s), directional
valve, load sense valve, and open center valve as
applicable).
Issue Possible Cause Solution
Left and right booms do not
move during calibration.
Proportional/blocker
connections are reversed
or improperly connected.
Check the connections on the AutoBoom valve to
ensure the harness cable connectors are inserted in
the correct ports.
Hydraulic connections are
improperly connected.
Trace the hydraulic lines connected to the AutoBoom
valve and verify they are properly routed and
tightened.
Booms are resting on the
stops or cylinders are fully
extended.
Manually raise the booms and lower the center rack
to ensure the pressure is sufficient in the hydraulic
system for calibration.
Pressure transducer or
connection is faulty.
Check the transducer connections to the AutoBoom
harness cable.
Insufficient high current
power supplied to the
AutoBoom node.
Check the AutoBoom harness power and ground
connections and the node connectors.
