6. FUNCTION LOCKOUT
Fault in crane electric, hydraulic system, or
electronic board.
PROBLEM: The lever lockout system of the crane is activated. Crane movements “hoist up” and (optional)
“boom down” are stopped. Only if the crane is not in overload or two-block condition continue with flow chart.
WARNING: If overload or A2B condition exists, use extreme caution and move the crane out of the
condition.
If Error Code is displayed goto Section 5.
Corrected
Check lever lockout
system in crane
service manual.
Relay defective on the main
board. Replace main board.
Refer to main board
replacement procedure.
The LMI by-pass warning light and/or anti-two-block
warning light is lit on the console.
LED's H1, H2, and H3 are lit on the main/terminal board.
The fault is located in LMI, cables,
wiring, fuses, or console.
Read error code displayed on console
and go to error code section.
Start
Use the console key switch and the LMI by-pass button or the central unit key switch to override the overload.
When by-passing the system, the following instructions must be obeyed:
y
The by-pass function shall be used with discretion, as unwarranted use of it to override the control lever
lockout system can result in harm to the crane and danger to property and persons.
y
Never use the by-pass function to either overload or operate the crane in a non-permissible range.
