Overload protection "OLP", warning signals
Blocking on max load/release
When a function has been blocked due to an OLP, a
cross is shown in the relevant lever's display when
an attempt is made to activate it.
If the crane has got stuck the release button must
be activated to enable it to be moved from it's posi-
tion. (2)
If the OLP release is accepted this is shown by an
unlocked padlock in the centre display. (3)
The crane will then operate at reduced speed for a
limited period of time.
"Release button"
Warning at 50%, 70%, 90% and 100%
Some of the crane's functions are connected to
pressure sensors which show the pressure in these
cylinders as a percentage of maximum permitted
pressure when it exceeds 50%.
The percentage is shown as 50%, 70%, 90% or
100% alternating with the lever's symbol, once per
second.
When a pressure sensor reaches 100% all motions
that would increase the load can be blocked.
These configurations are set by the crane manufac-
turer.
If the operator attempts to activate a blocked func-
tion a cross replaces the symbol. The cross disap-
pears and the symbol returns when the lever is
returned to the neutral position. (4)

Technical description
Configuration
The hand controller must be configured specifi-
cally for the particular crane or vehicle if it is to
show the correct symbol or text.
Default settings for the crane symbols are set in
the factory during final testing. Configuration of
other functions and tools is conducted by the coach
builder when mounting the crane on the vehicle.
Cranes that have a safety system can utilise the
terminal program to configure the crane. Non-CE
cranes without a safety system can be configured
via a computer or be adjusted in the factory.
