A typical OCX 8800 Oxygen/Combustibles Transmitter package should contain the items shown in Figure 1-1.

Use the product matrix in Table 1-1 at the end of this section to verify your order number. The first part of the matrix defines the model. The last part defines the various options and features of the OCX 8800. Check the model number against the transmitter features and options, making sure options specified by this number are on or included with the unit. Use this complete model number for any correspondence with Emerson Process Management. A list of accessories for use with the OCX 8800 is provided in Table 1-2.

Scope

This Instruction Manual supplies details needed to install, startup, operate, and maintain the OCX 8800. Signal conditioning electronics outputs separate 4-20 mA signals representing oxygen (O2) and combustibles (COe) values. This information, plus additional details, can be accessed with the HART Model 275/375 handheld communicator or Rosemount Analytical AMS software. The local operator interface (LOI) also provides a communications interface with the electronics.

System Description

The OCX 8800 is designed to measure oxygen and combustible concentrations in flue gas temperatures up to 2600°F (1427°C). Electrical connections, power and communications are made through two 3/4 NPT ports in the flameproof electronics enclosure using fittings and cables provided by the customer. Cable installation must meet NEC, IEC and/or other applicable national or local codes for Class I, Zone 1, Group IIB +H2 T3/T6 permanently mounted equipment. The transmitter is close coupled to the process and requires minimal sample conditioning requirements.
