8.2.2.4 Application Settings
By default, the Oil Condition Warning and Alarm levels are set to that of a Diesel Engine.
However, every application is unique, and some adjustments may help optimise the system.
Tan Delta have recommended settings for several applications listed in Figure 30 which you can
use for configuring the OQDe. Alternatively, if a bespoke solution is required, we recommend
logging data for one oil change cycle, or six to eight weeks, and then sending the data to
support@tandeltasystems.com . We can then advise you on your application settings.
