Example for service level (A):
The figures at the left are the programmed service intervals. For Service interval A, the programmed
number of running hours is 4000 hours (upper row) and the programmed number of real time hours is 8760
hours, which corresponds to one year (second row). This means that the regulator will launch a service
warning when either 4000 running hours or 8760 real hours are reached, whichever comes first. Note that
the real time hours counter keeps counting, also when the regulator is not powered.
The figures within the bars are the number of hours to go till the next service intervention. In the example
above, the Dryer was just started up, which means it still has 4000 running hours or 8280 hours to go
before the next Service intervention.
Service plans
A number of service operations are grouped (called Level A, Level B, etc.). Each level stands for a number
of service actions to be carried out at the time intervals programmed in the Airlogic® regulator. When a
service plan interval is reached, a message will appear on the screen. After carrying out the service actions
related to the indicated levels, the timers must be reset.
From the Service menu above, select Service plan (3) and press Enter. Following screen appears:
