Table 19: Relay Indicators
Relay Indicator Description
Status
Shows the current state of the Status relay.
•
Solid Green – Normal: No fault conditions noted in any of
the parameters monitored by the analyzer. Analyzer can
analyze process sample.
•
Flashing Red – Fault: At least one fault condition is noted
in the parameters monitored by the analyzer. Analyzer is
incapable of analyzing process sample until all current fault
conditions are cleared.
Service
Shows the current state of the Service relay
•
Solid Green – Normal: No warning conditions noted in any
of the parameters monitored by the analyzer. If Status relay
is also green, no maintenance is currently required, and
analyzer condition is completely normal.
•
Flashing Red – Warning: At least one warning condition
noted in parameters monitored by the analyzer. If Status
relay is green, analyzer is still capable of analyzing process
ample, but maintenance should be scheduled as soon as
possible to resolve warning condition.
Mode
Shows the current state of the Mode relay
•
Solid Green – Run: Analyzer is not carrying out a zero-
calibration cycle. If Status relay is also green, analyzer is
currently monitoring process sample.
•
Flashing Red – Calibrate: Analyzer is currently carrying out
a zero-calibration cycle, either automatically initiated by
timed schedule, or manually initiated from keypad or web
GUI.
Control
Shows the current state of the Control relay
•
Solid Green – Auto: Analyzer is currently in automatic
control, which means that analyzer output signals can be
considered valid values and can be used for plant control
purposes if required.
•
Flashing Red – Manual: Analyzer is currently in manual
control, either as a result of fault condition(s) being present,
the analyzer being placed into Offline mode, or due to a
zero-calibration cycle (manual or automatic) being in
progress. Analyzer output signals should be deemed to be
invalid and NOT used for plant control purposes.
5.2.1.4 Air Demand and H2S/SO2 Trends
The Air Demand Trend and H2S/SO2 Trend displays show the graphical trend in these
results over the past 17 minutes. They are updated once ever second, and the latest
reading is at the extreme right of the each of the trend lines. The shaded areas shown
above and below the trend lines in Figure 48 indicates the distance between the current
trend line and the zero baseline. The colour code of the trend lines is the same as the
colour code of the numerical data fields in the Value Display section.
