below the levels for more than the set time delays the corresponding signals,
PRES_ALM, pressure below alarm level and PRES_LO, pressure below lockout level
alarm will be obtained.
The input signal BLK_ALM is used to block the two alarms levels. The input signal
BLOCK is used to block both the alarms and the function.
