When the PRESALM binary input is activated, the GPRESALM output is activated after
a time delay set with the tDGasPresAlm setting. The GPRESALM alarm can be blocked
by activating the BLKALM input.
If the pressure drops further to a very low level, the PRESLO binary input goes high,
activating the lockout alarm GPRESLO after a time delay set with the tDGasPresLO
setting. The GPRESLO alarm can be blocked by activating the BLKALM input.
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 BLKALM.
