17. CHECKING WIRING FUNCTIONALITY
If a fault occurs it can be useful to simulate the operation of certain wiring components, to find out if
the origin of the problem is in wiring or in a single component (microswitch, position of lever on control
bank, pressure sensors, angular sensors).
To determine if the fault is located in pressure sensors or angular sensors, rather than in the wiring,
you must use a 2k2 Ohm (2200 Ohm) heated
wire of at least 3 Watt. This heated wire must be
included in connectors instead of sensors that
should be checked.
NOTE: An electric by-pass is useful for diagnostics only.
It is absolutely forbidden to use the crane with an electric by-pass connected.
