CARGOMASTER®5
Operators Manual - 20
Here, we have enabled alarms for 98%, 95% and for a difference in density of
more than 0.05 T/m³ between the OD1 value (See above) and the actual
measured density.
Pressing the More Alarms button will open for even more alarm options,
however not necessarily relevant to a loading situation… Alarm limits and
enabling may also be found in the ValueTable view (Alt + F3).
Zero adjust – sensor optimization
There is one final step to this sequence. The zero adjustment of any pressure
sensors found in the tanks belonging to this group. However, some restrictions
for zero adjustment apply:
• To zero adjust any Inert Gas Pressure (IGP) sensors, the tank must be open
to air.
• To zero adjust any bottom or upper sensors, the sensors cannot be
submerged in fluid.
• Temperature elements do not normally need zero adjustment.
• The atmospheric (reference) sensor should NOT be adjusted!
We recommend zero adjustment to be performed immediately before loading.
More details about this issue are found in Zero adjustments on page 36.
Bringing the new condition online
With our new condition running in Planning mode, we are now ready to start
loading. Or are we?
In the opening of the chapter “A planning Example” we wrote that
It is not recommended to run any conditions in planning mode during load
or discharge operations
And why is that? When running in planning mode, data will not be updated in
the ordinary views. Any warnings or info that displays in the Online Window
will only be valid for the currently running online condition, and so will any
active alarms. This means we will have to bring our planning condition Online
before attempting to start the loading operations.
