Hazardous Area Oxymitter 5000
For optimum performance, Emerson Process Management recommends
connecting the output to a Potter & Brumfield 3.2 mA DC relay
(P/N R10S-E1Y1-J1.0K).
Of the ten modes in Table 3-1, modes 0 through 7 are the alarm modes. The
factory default is mode 5 for Hazardous Area Oxymitter 5000 units without an
IMPS 4000 or SPS 4001B. In this mode, the output will signal when a unit
alarm or a CALIBRATION RECOMMENDED indication occurs.
Calibration Handshake Signal
If using an optional IMPS 4000 or SPS 4001B, the logic I/O must be
configured for calibration handshaking. Of the ten modes in Table 3-1 only
modes 8 and 9 are configured for calibration handshaking. For a Hazardous
Area Oxymitter 5000 with an IMPS 4000 or an SPS 4001B, the factory sets
the default to mode 8. In this mode, the logic I/O will be used to communicate
between the Hazardous Area Oxymitter 5000 and the sequencer and to signal
the sequencer when a CALIBRATION RECOMMENDED indication occurs.

Mode Configuration
0 The unit is not configured for any alarm condition.
1 The unit is configured for a Unit Alarm.
2 The unit is configured for Low O
2
.
3 The unit is configured for both a Unit Alarm and Low O
2
.
4 The unit is configured for a High AC Impedance/CALIBRATION
RECOMMENDED.
5* The unit is configured for both a Unit Alarm and a High AC
Impedance/CALIBRATION RECOMMENDED.
6 The unit is configured for both a Low O
2
and High AC Impedance/CALIBRATION
RECOMMENDED.
7 The unit is configured for a Unit Alarm, a Low O
2
, and a High AC
Impedance/CALIBRATION RECOMMENDED.
8** The unit is configured for a calibration handshake with IMPS 4000 or SPS 4001B.
CALIBRATION RECOMMENDED will initiate the calibration cycle.
9 The unit is configured for a calibration handshake. CALIBRATION
RECOMMENDED will not initiate the calibration cycle with the IMPS 4000 or SPS
4001B.
