the process is not in operation.
Case 2. One of the impulse lines of DP is blocked and
the other side is open to atmosphere or has a constant
pressure.
Case 3. Both sides of the impulse lines are blocked.
Case 4. Noise in process is too low.
Resolution:
For case 1, just ignore the alarm. It's suggested that
PILD be enabled only after the transmitter is installed
and the process is running.
For case 2
