EVENT REPORTED by SAM GUARD®

Detected a rise in SP. In most cases, we don’t forward to customer issues related to SP changes, since it’s usually a planned changed. In this case, we see that persistently PV is unable to reach SP.

PROCESS ENG TEAM FINDINGS

Apparently, customer has started using a new control system that automatically changes SP because of changes in final product (APC). Due to SAM GUARD® it was found that that system is asking the valve to reach SP which it is uncapable of ever reaching.

COST / DOWNTIME AVOIDED

This is impacting the final product.

CUSTOMER FEEDBACK

Customer had to set upper limit to SP in APC software.
