Equipment Related Items: Measuring gas selection
Output Related Items: Analog output/output mode selection, output conditions when warming-
up/maintenance/calibrating (during blow back)/abnormal, 4 mA/20 mA
point oxygen concentration (vol% O
2
), time constant.
Alarm Related Items: Oxygen concentration high alarm/high-high alarm limit values (vol% O
2
),
oxygen concentration low alarm/low-low alarm limit values (vol% O
2
),
oxygen concentration alarm hysteresis (vol% O
2
), oxygen concentration
alarm detection, alarm delay (seconds)
Contact Related Items: Selection of contact input 1 and 2, selection of contact output 1 to 4
(abnormal, high-high alarm, high alarm, low alarm, low-low alarm,
maintenance, calibrating, range switching, warming-up, calibration gas
pressure decrease, temperature high alarm, blow back, ameout gas
detection, calibration coefcient alarm, stubilization timeout)
Converter Output: Two points mA analog output (4 to 20 mA DC (maximum load resistance
of 550 Ω)) and one mA digital output point (HART) (minimum load
resistance of 250 Ω).
Range: Any setting between 0 to 5 through 0 to 100 vol% O
2
in 1 vol% O
2
, or
partial range is available (Maximum range value/minimum range
value 1.3 or more).For the log output, the minimum range value is xed
at 0.1 vol% O
2
.
4 to 20 mA DC linear or log can be selected. Input/output isolation
provided.
Output damping: 0 to 255 seconds.Hold / non-hold selection, preset value setting
possible with hold.
Contact Output: Four points, contact capacity 30 V DC 3 A, 25 0V AC 3 A (resistive load)
Three of the output points can be selected to either normally energized
or normally de-energized status.
Delayed functions (0 to 255 seconds) and hysteresis function (0 to 9.9
vol% O
2
can be added to high/low alarms.
The following functions are programmable for contact outputs.
(1) Abnormal, (2) High-high alarm, (3) High alarm, (4) Low-low alarm,
(5) Low alarm, (6) Maintenance, (7) Calibration, (8) Range switching
answer-back, (9) Warm-up, (10) Calibration gas pressure decrease
(answer-back of contact input), (11) Temperature high alarm,
(12) Blow back start, (13) Flameout gas detection (answer-back of
contact input), (14) Calibration coefcient alarm, (15) Startup power
stabilization timeout alarm
Contact output 4 is set to normally operated, and xed error status.
Contact Input: Two points (voltage-free)
The following functions are programmable for contact inputs:
(1) Calibration gas pressure decrease alarm, (2) Range switching
(Switched range is xed), (3) External calibration start, (4) Process alarm
(if this signal is received, the heater power turns off), (5) Blow back start
Contact capacity: Off-state leakage current: 3 mA or less
Self-diagnosis: Abnormal cell, abnormal cell temperature (low/high), abnormal
calibration, defective A/D converter, defective digital circuit
Calibration:
Method; zero/span calibration
Calibration mode; automatic, semi-automatic and manual (All are operated interactively
with an LCD touchscreen). Either zero or span can be skipped.
