e) The warning light 7 is turned on with series of two flashes
The DMU entered Stand-By mode (30 minutes have passed since the crane has been moved for the last
time) –
SOLUTION press the emergency stop button, release it or press the reset button either on its
panel or on the DMU panel , or on its remote control push-button panel – if tted –
f) The warning light 7 is turned on intermittently, and it
has an acoustic alarm of the intermittent/slow type Bip.…Bip.…Bip….
A pressure value equal to 90% of the maximum pressure value has been reached in a cylinder related
to boom lifting
SOLUTION the crane can operate with the speed reductions provided for the specic project.
g) One or several warning lights 1, 2, 3,
is turned on intermittently, and an acoustic alarm
of the intermittent/quick type is emitted. Bip -Bip - Bip - Bip - Bip
In the boom lifting cylinder related to the warning light which is turned on, the maximum allowed
pressure value for the project has been reached.
SOLUTION the crane can operate with the restrictions due to the load limiting device operation.
h) One or several warning lights 1, 2, 3 is turned on permanently and a continuous
acoustic alarm is emitted. Biiiiiiiip
A sharp load manoeuvre has created a pressure value higher than the maximum allowed pressure value
for the project within the boom lifting cylinder related to the warning light which is turned on.
SOLUTION the crane can operate only while carrying out the hydraulic extension retraction
manoevres.
