Operation and Maintenance
3.2 Proof test
The purpose of proof testing is to identify dangerous undetected failures. Proof testing may
be divided into comprehensive and partial testing. For the Rosemount
™
5900 Radar Level
Gauge and the Rosemount 2410 Tank Hub, a comprehensive proof test includes the
following functional elements:
Output circuitry (relay, analog output)
Measurement electronics (digital signal processing)
Sensing element (antenna, microwave unit)
A partial test may include one or more of these elements.
The Rosemount TankMaster software supports proof testing of the Rosemount 5900 Level
Gauge and the Rosemount 2410 Tank Hub.
The Rosemount Tank Gauging Safety System should be checked at regular intervals in order
to detect Dangerous Undetected (DU) failures. The time periods depend on the PFD
avg
value.
Note
Proof test for PFD
avg
calculations is only applicable for Low Demand mode.
One or more of the proof tests described below are recommended.
Make sure to enable write protection as soon as you are finished.
Note
The Rosemount 5900 gauge is not safety-rated during maintenance work, configuration
changes, or other activity that affects the Safety Function. Alternative means should be
used to ensure process safety during such activities.
Note
Before every test, make sure you are connected to the correct transmitter by verifying S in
the model code on the label and your software version. Also verify that the Device Id on the
label matches the one in your configuration tool.
