INSTALLATION

NOTE

If interconnect cable was not purchased with the Oxymitter 4000, consult the factory for the proper wire type and gauge.

1.Remove cover (27, Figure 9-4) from junction box (5). Connect the electronics end of the interconnecting cable (9) to the "FROM PROBE" side of terminal block (Figure 2-10).

2.Remove cover (27).

3.See (Figure 2-10). Connect the heater power leads, the thermocouple leads, and the oxygen signal leads of the interconnecting cable to the terminal block. The cable leads are tagged for polarity. To avoid a shock hazard, the heater power terminal cover must be installed.

4.Install covers (27, Figure 9-3 and Figure 9-4).

OXYMITTER 4000

Reference Air Package

After the Oxymitter 4000 is installed, connect the reference air set to the Oxymitter 4000. Refer to Figure 2-11.

Instrument Air (Reference Air): 10 psig (68.95 kPag) minimum, 225 psig (1551.38 kPag) maximum at 2 scfh (56.6 L/hr) maximum; less than 40 parts per million total hydrocarbons. Regulator outlet pressure should be set at 5 psi (35 kPa). Reference air can be supplied by the reference air set of the IMPS 4000 or SPS 4001B.

If using an IMPS 4000, refer to the IMPS 4000 Intelligent Multiprobe Test Gas Sequencer Instruction Manual for the proper reference air connec- tions.

If using an SPS 4001B, refer to the SPS 4001B Single Probe Autocalibra- tion Sequencer Instruction Manual for the proper reference air connec- tions.

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 hydrocarbon concentrations of more than 40 parts per million. Failure to use proper gases will result in erroneous readings.

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.
