4.7.8 Option oe
Sealed floor pan option
The machine is fitted with a sealed floor pan. In the event of a leak, any leaking liquids required for
the machine's operation are caught in the floor pan.
The sealed floor pan:
■ Cannot catch all liquids contained in the machine, but is intended only to capture small
leaks in the vicinity of endangered components.
■ Is equipped with service openings which are closed with plugs. These openings must be
tightly re-closed after performing any cleaning work.
When other components are removed from the sealed floor pan, (for example the sheet metal
cover) they must be properly resealed prior to installation.

Fluid sensors in the sealed floor pan
If leaks occur, fluids will collect in recesses within the floor pan.
Sensors are installed in those areas that recognize the presence of fluids, and send a correspond‐
ing message to the SIGMA CONTROL MOBIL controller.
In the event of a fault, the controller will prevent the engine from starting or automatically shuts the
engine off.
4.7.9 Option rw, rx, oe
Location of draining points for the machine's fluids
Compressor cooling oil and engine coolant drain lines are led to a central point outside the ma‐
chine on stationary machines and machines with a sealed floor pan. These are located at the rear
of the machine, in a recessed connection box. The box can be accessed from below by removing a
cover.
