"Rotarex" gas limit display operating instructions
Functional description
The gas limit display is a threshold device for
the fluid phase, known as an MLD (Minimum
Liquid Detector). The MLD indicates when
there is just a small amount of gas left in
the container. The remaining travel time will
then depend on the application and ambient
conditions. Normally it is 8 - 12 minutes. This
is then displayed via the spare indicator (2) on
the dashboard.
Z
Note: if the container level is low, the spare
indicator can briefly light up or flicker due to
fluctuations in the liquid gas level produced
during travel. Only when the indicator is permanently lit does this indicate that the tank
is almost empty.
M
