EVP management
If the valve is set as ON-OFF the MIN EVP parameter is disabled and the current
set point applied to the valve is only dependent by MAX EVP.
The dynamic delay seen during the modification of the current set point, in both
cases, ANALOG Valve and ON/OFF Valve, is dependent by the OPEN DELAY
and CLOSE DELAY parameters (see paragraph 8.2.1).
OPEN DELAY determines the current increase rate on EVP and it sets the time
needed to increase the current to the maximum permitted value.
CLOSE DELAY determines the current decrease rate on EVP and sets the time
needed to decrease the current from the maximum value to minimum.
EVP Set point.
Example 1:
The lowering output is set to ANALOG and the descent request consists of a step
whose width corresponds to MAX EVP.
