Spray And Adiabatic Panel Hours Control - LU-VE Emeritus LU1W Manual De Usuario

10.1 Spray and Adiabatic Panel Hours Control

For each spray sector and for the adiabatic panels present on each side of the exchanger, the total operating hours
and annual operating hours are stored. Each year the annual operating hours are automatically reset; the reset date is
given by PH96 and PH97.
If the annual operating hours of the sprayers and adiabatic panels exceed the set thresholds, parameter PA04 for
sprays and parameter PA05 for adiabatic panels, the controller gives a warning alarm.
For the spray sector only, the resource is blocked from exceeding an additional 10% above the set threshold (i.e. block
occurs when the annual hourly total reaches PA04 * 1.1).
