Pressure change was due to incorrect wiring of PT-120 during Beckhoff transition and was brought to light when Gerardo incorporated signal wiring for AIPs and needed to turn off PT180 this week. Pressure reading now is correct (and the same as it was in Q2 2016). We should check other gauges to be sure they are wired properly and reading correct pressures.
Wearing laser safety glasses contributes to issues like this because visibility is compromised.
Probably gauge problem since 114 did not follow.
Some more gauges -
