Replacing the electronics module

of a revolution after the cover begins to compress the O-ring. Both
transmitter covers must be fully engaged to meet explosion proof requirements.
5.2.4 Transmitter diagnostics logging
The Transmitter Diagnostics Logging feature stores advanced diagnostic information between device
resets, such as what caused the transmitter to go into alarm, even if that event has disappeared. For
example, if the transmitter detects an open sensor from a loose terminal connection, the transmitter will
go into alarm. If wire vibration causes that wire to begin making a good connection, the transmitter will
come out of alarm. This jumping in and out of alarm is frustrating when trying to determine what is
causing the problem. However, the Transmitter Diagnostics Logging feature keeps track of what caused
the transmitter to go into alarm and saves valuable debugging time. The log may be viewed using an
asset management software, such as AMS Device Manager.
