Install all protective equipment covers and safety ground leads before equipment startup.
Failure to install covers and ground leads could result in serious injury or death.
Verify Mechanical Installation
Ensure the Two-Wire In-Situ Oxygen Analyzer is installed correctly. See
Mechanical Installation in Section 2: Installation for mechanical installation
information.
Verify Terminal Block Wiring
Ensure the wiring of both the oxygen probe terminal block and Rosemount
5081 transmitter terminal block is correct. Refer to Electrical Installation in
Section 2: Installation for electrical installation and wiring information.
General
The Two-Wire In-Situ Oxygen Analyzer displays the current oxygen reading
on the LCD face of the Rosemount 5081 transmitter. The O
cell temperature, and 4-20 mA output current are displayed as shown in
Figure 3-1. This and other information may also be accessed using
HART/AMS.
Startup Display
When the probe is first inserted into the stack, some time is required until the
minimum operating temperature [550°C (1022°F)] is reached. Some time is
also required for the electronics to reach an operating state. Therefore, when
the unit is first powered up, a faulted operation display as shown in Figure 3-2
may be displayed by the transmitter until the probe operating temperature is
reached and the electronics are working properly (approximately 5 minutes).
