2-14 Installation Rosemount Analytical Inc. A Division of Emerson Process Management
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 be
mounted 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 9-3 and
Figure 9-4) and secure with captive
washers (20), cover locks (19), and
screws (18).
2-4 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).
