STARTUP AND OPERATION

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.

3-1 GENERAL

a.Verify Mechanical Installation

Ensure the Two-Wire In Situ Oxygen Ana- lyzer is installed correctly. See paragraph

2-2for mechanical installation information.

b.Verify Terminal Block Wiring

Ensure the wiring of both the oxygen probe terminal block and Model 3081 Transmitter terminal block is correct. Refer to paragraph 2-3for electrical installation and wiring information.

3-2 POWER UP

a.General

The Two-Wire In Situ Oxygen Analyzer dis- plays the current oxygen reading on the LCD face of the Model 3081 Transmitter. The O2 concentration, cell temperature, and 4-20 mA output current are displayed as shown in Figure 3-1. This and other infor- mation may also be accessed using HART/AMS.

b.Startup Display

When the probe is first inserted into the stack, some time is required until minimum operating temperatures [550°C (1022°F)] are 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 Fig- ure 3-2 may be displayed by the transmitter until the probe operating temperatures are reached and the electronics are working properly (approximately 5 minutes).

c. Operating Display

After the probe has reached operating temperatures, the Model 3081 Transmitter display should look similar to Figure 3-1.

The display will now track the O2 concentra- 3 tion, cell temperature, and 4-20 mA output

current.
