The activation of the 4 spray nozzles occurs alternatively on the two sides, the activation of the adiabatic panels is
subordinate to it. When activating the first spray step (priority is given to the sector with the lowest operating hours),
the adiabatic panels on the opposite side are activated at the same time (with any delay adjustable at parameter
PR40). On activating the second spray ramp, on the opposite side of the first, the second adiabatic panel is activated.
From this point there will be active sprayers and adiabatic panels on both sides of the machine. As the request grows,
the 2 ramps that are still inactive will be activated in sequence.
The machines are equipped with a collecting tank to retrieve the water sprayed on the coil; the water is then reused
to wet the adiabatic panels before being wasted. If the pump in the collecting tank is in alarm (acquired by DI10
input), the controller response depends on the parameter PA08 setting:
•
no action
•
turning off the pump and closing the solenoid valves for the adiabatic panels
•
turning off the pump and supplying the adiabatic panels from water mains.
