PRODUCT TIP - Use Group
Trending to Set Alarm Levels
Last issue we discussed a
strategy for on site alarms. This issue
we will talk about how to use FleetOil to determine workable alarm limits for
wear metals.
Alarm limits for fluid
properties such as viscosity and contamination need to be considered
separately. Strategies for dealing with these
are more clear cut.
Wear metals are tougher to deal with due to the natural variation
between machinery types, local conditions and application. All these factors make it tough to set alarm limits
across the board for machine types.
So what can be done? One strategy is to consider the sample
history for your site for each machine type and determine alarms accordingly.
FleetOil provides the powerful ability to visually compare results for all
machines of a particular type on the one graph.
This means you can eyeball years of data in one fell swoop and choose an
alarm level by eye.
*** Note: Appropriate Alarm
Groups must be set up for this feature to work.
Alarm groups should correspond with machine types. For e.g. all Haul Truck Engines of a particular
model would be in the same alarm group.
How To
Get There:
- Start FleetOil
- On the main menu, click
Trends
- On Trend Viewer, browse to
the equipment that is part of your target Alarm Group.
- Set up the view so that
your target wear metal is on the graph (e.g. FE for iron)
- Click on the wear metal on
the legend - you should see it highlighted with a box.
- Click on the Alarm Group
Graph tab. This will take you to a scattergram of all results for the chosen wear metal for
that alarm group.
Taking failure history into
account and the spread of the data, choose a value that would have resulted in
an acceptable number of alarms historically.
This method is not exact but neither are test results. It is important to trend the results and this
method takes site and machine specific behaviour into
account.
