Oxymitter 4000

Table 4-1. Logic I/O Configuration (as set at HART/AMS or LOI)

Of the ten modes in Table 4-1,mode 1 through mode 7 are the alarm modes. The factory default is mode 5 for Oxymitter 4000 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 4-1,only modes 8 and 9 are configured for calibration handshaking. For an Oxymitter 4000 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 Oxymitter 4000 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 O2.
3	The unit is configured for both a Unit Alarm and Low O2.
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.

6The unit is configured for both a Low O2 and High AC Impedance/CALIBRATION

RECOMMENDED.

7The unit is configured for a Unit Alarm, a Low O2, 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.

9The unit is configured for a calibration handshake. CALIBRATION RECOMMENDED will not initiate the calibration cycle with the IMPS 4000 or SPS 4001B.
