The following report was received via e-mail:
On August 30, 2017, the licensee noticed that a shutter indicator light on a Pm-147 Honeywell-Measurex fixed gauge device, on a paper mill line, was not functioning correctly. The light was on and indicating that the shutter was closed, when the shutter was actually in the open position. However, the device shutter is still working and communicating as usual. The licensee utilized a survey meter to determine that even though the light was on, the shutter was open. The licensee roped off the area, instructed all operators to the status of the shutter, and re-instructed to always use a survey meter if they needed to approach the device and to assume the shutter is open. The licensee is continuing operations, but controlling access to the area while a fix is arranged. The licensee is in contact with the manufacturer to determine the next steps. The state is in contact with the licensee and will be continuing to follow the situation.
