Instruction Manual IM-106-880, Rev 2.0 September 2009 SYSTEM OVERVIEW OCX 8800 Scope This Instruction Manual supplies details needed to install, startup, operate, and maintain the OCX 8800. Signal conditioning electronics outputs a digital signal representing oxygen (O2) and combustibles (COe) values. This information, plus additional details, can be accessed with the 375 Field communicator or Emerson Process Management AMS software.
Instruction Manual IM-106-880, Rev 2.0 September 2009 OCX 8800 The OCX 8800 measures net oxygen concentration in the presence of all the products of combustion, including water vapor. Therefore, it may be considered an analysis on a "wet" basis. In comparison with older methods, such as the portable apparatus, which provides an analysis on a "dry" gas basis, the "wet" analysis will, in general, indicate a lower percentage of oxygen.
Instruction Manual IM-106-880, Rev 2.0 September 2009 OCX 8800 The power supply can accept voltages of 100 to 240 VAC and 50 to 60 Hz. The electronics accepts millivolt signals generated by the sensors and produces the outputs to be used by remotely connected devices. Refer to Section 3, Configuration and Startup for specific instructions upon initial power up. System Features 1. The O2 cell output voltage and sensitivity increase as the oxygen concentration decreases. 2.
Instruction Manual IM-106-880, Rev 2.0 September 2009 OCX 8800 System Operation Figure 1-2 shows the relationship between the components of the OCX 8800. The sensors and the electronics are contained in separate housings. The sensor housing and probe mounts to a duct or process wall so that the probe protrudes into the flue gas stream.
Instruction Manual IM-106-880, Rev 2.0 September 2009 OCX 8800 Handling the OCX 8800 It is important that printed circuit boards and integrated circuits are handled only when adequate antistatic precautions have been taken to prevent possible equipment damage. The OCX 8800 is designed for industrial application. Treat each component of the system with care to avoid physical damage. The probe may contain components made from ceramics, which are susceptible to shock when mishandled.

Instruction Manual IM-106-880, Rev 2.0 September 2009 CALIBRATION TOLERANCE FEATURE OCX 8800 The calibration tolerance feature provides a mechanism to fail a calibration if the calibration measurement does not fall within a specific tolerance of the test gas value. The tolerance is preset within the OCX 8800 software and is not user adjustable. The tolerance is different between the oxygen and combustibles test gases.
Instruction Manual OCX 8800 COe PURGE / ZERO FEATURE IM-106-880, Rev 2.0 September 2009 This feature provides a way to periodically flood the COe sensor with air to perform two functions; a) provide additional oxygen to help burn off any combustible residue from the COe sensor, and b) allow for optional adjustment of the COe calibration constant. If the OCX8800 is configured to update the COe calibration constant, only the constant is updated. The COe calibration slope is not affected.

Instruction Manual IM-106-880, Rev 2.0 October 2009 OCX 8800 Application Information The PID function block is a powerful, flexible control algorithm that is designed to work in a variety of control strategies. The PID block is configured differently for different applications. The following examples describe the use of the PID block for closed-loop control (basic PID loop), feedforward control, cascade control with master and slave, and complex cascade control with override.
Instruction Manual IM-106-880, Rev 2.0 October 2009 OCX 8800 • Local Override is a non-target mode that instructs the block to revert to Local Override when the tracking or fail-safe control options are activated. • Out of Service mode disables the block for maintenance. Abrupt changes in the quality of the input signal can result in unexpected loop behavior. To prevent the output from changing abruptly and upsetting the process, select the SP-PV Track in Man I/O option.

Instruction Manual IM-106-880, Rev 2.0 October 2009 OCX 8800 Solution If the flow is controlled, steam pressure variations will be compensated before they significantly affect the heat exchanger temperature. The output from the master temperature loop is used as the setpoint for the slave steam flow loop.
Instruction Manual IM-106-880, Rev 2.0 October 2009 OCX 8800 If the instrument connected to the AI block fails, you can place the AI block in Manual mode and set the output to some nominal value for use in the Integrator function block. In this case, IN at the slave PID block is constant and prevents the integral term from increasing or decreasing. Figure 7-21.

Instruction Manual IM-106-880, Rev 2.0 October 2009 OCX 8800 Compensation Input Calculations For each of the inputs IN_1, IN_3, IN_4 there is a gain and bias. The compensation terms (t) are calculated as follows: • When IN_(k) is usable: t(k) = GAIN_IN(k) * (BIAS_IN(k) + IN_(k)) • When IN_(k) is not usable, then t(k) gets the value of the last t(k) computed with a usable input.
Instruction Manual IM-106-880, Rev 2.0 October 2009 OCX 8800 This allows a ratio to be set up that increases the level indication at block output for an increase in the tank temperature relative to ambient temperature. Figure 7-25.
