IB-106-340C Rev. 4.1 July 2004

Hazardous Area Oxymitter 4000

If using an IMPS 4000 or an SPS 4000, install it in a non-hazardous, explosive- free environment.

2.Calibration Handshake/Logic I/O. The output signal can be used to trigger an alarm or to provide a calibration hand- shake signal to an IMPS or SPS 4000.

If autocalibration is not utilized, a common bi-directional logic contact is provided for any of the equipment alarms listed in Table 8-1.The assign- ment of alarms that will actuate this contact is modified by one of seven additional configuration settings (mode 1 through mode 7) listed in Table 4-1.

The logic contact is self-powered,

+5 VDC, with a 340 ohm series resis- tance. An interposing relay is required if the logic contact will annunciate a higher voltage device, such as a light or horn. An interposing relay may also

be required for certain DCS input cards. A Potter & Brumfield model R10S-E1Y1-J1.0K 3.2 mA DC (or

equal) interposing relay will be2-4mounted where the contact wires

terminate in the control/relay room.

d.Install cover (17, Figure 9-4)and secure with captive washer (20), cover lock (19), and screw (18).

e.Install Interconnecting Cable

NOTE

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

1.Remove cover (17, Figure 9-4)from the junction box (24). Connect the electronics end of the interconnecting cable (30) to the “FROM PROBE” side of the terminal block (Figure 2-10).

If using an IMPS 4000 or an SPS 4000, install it in a non-hazardous, explosive- free environment.

2.Loosen screw (18, Figure 9-3),cover lock (19) and washer (20) at the probe head. Remove cover (17).

3.See (Figure 2-10). Connect the heater power leads, the thermocouple leads, and the oxygen signal leads of the in- terconnecting 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 (17, Figure 9-3and Figure 9-4)and secure with captive washers (20), cover locks (19), and screws (18).

PNEUMATIC INSTALLATION

a.Reference Air Package

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

Instrument Air (Reference Air): 68.95 kPa gage (10 psig) minimum, 1551.38 kPa gage (225 psig) maximum at 0.5 scfm (0.25 l/hr) maximum; less than 40 parts-per-million total hydrocarbons. Regulator outlet pres- sure should be set at 35 kPa (5 psi).
