The gas pressure is monitored through the binary input signals LOPRES and ALMPRES.
Pressure alarm time delay
When the ALMPRES binary input is activated, the PRESALM alarm is activated after a time delay set

The binary input BLOCK can be used to block the function. The activation of the BLOCK input
deactivates all outputs and resets internal timers. The alarm signals from the function can be
blocked by activating the binary input BLK_ALM.
