Emerson Process Management IB106-340 Pneumatic Installation for OXY- Mitter 4000 with SPS

Oxymitter 4000

Instruction Manual

IB-106-340 Rev. 2.4 April, 2001

Do not use 100% nitrogen as a low gas (zero gas). It is suggested that gas for the low (zero) be between 0.4% and 2.0% O2. Do not use gases with hy- drocarbon concentrations of more than 40 parts per million. Failure to use proper gases will result in errone- ous readings.

b.Calibration Gas

Two calibration gas concentrations are used with the Oxymitter 4000, Low Gas - 0.4% O2 and High Gas - 8% O2. See Figure 2-12for the Oxymitter 4000 connections.

2-5 PNEUMATIC INSTALLATION (FOR OXY- MITTER 4000 WITH SPS 4000)

Do not use 100% nitrogen as a low gas (zero gas). It is suggested that gas for the low (zero) be between 0.4% and 2.0% O2. Do not use gases with hy- drocarbon concentrations of more than 40 parts per million. Failure to use proper gases will result in errone- ous readings.

! NOTE

Locate the 1/4 in. calibration gas fittings on the SPS 4000 manifold (Figure 2-2). Con- nect O2 calibration gas 1 (high calibration gas) to the HIGH CAL GAS IN fitting and O2 calibration gas 2 (low calibration gas) to the LOW CAL GAS IN fitting. Ensure the cali- bration gas pressure is set at 20 psi

(138 kPa).

a.Reference Air Connection (Optional)

If the reference air option (which includes the reference air flowmeter, pressure regu- lator, and necessary tubing and fittings) is used, connect the instrument air to the 1/4 in. fitting on the reference air pressure regulator (Figure 2-2).The pressure regu- lator is factory set at 20 psi (138 kPa). Re- adjust by turning the knob on the top of the regulator to obtain the desired pressure.

If the SPS 4000 does not have the refer- ence air option, connect the reference air to the Oxymitter 4000 as instructed in para- graph 2-4.

Upon completing installation, make sure that the Oxymitter 4000 is turned on and operating prior to firing up the combustion process. Damage can result from having a cold Oxymitter 4000 exposed to the process gases.

During outages, and if possible, leave all Oxymitter 4000 units running to prevent condensa- tion and premature aging from thermal cycling.

If the ducts will be washed down during outage, MAKE SURE to power down the Oxymitter 4000 units and remove them from the wash area.
