Multiplexing 195
Should the system issue a warning or caution message, it will appear on the Main Page.
For example, if the following caution message “Pump Not Started: Main Air Pressure” is issued by the
system, it will appear on the Main Page of the monitor. An action that could be taken by the operator,
when faced with such a situation, would be to wait until the required main air pressure level is
reached.
For a specific problem or condition that requires special attention, the multiplexed system can alert
the operator to a possible cause, which appears in bold and large print on the monitor screen (active
cause). The operator should check if the problem stems from the highlighted or active cause. One
possible cause is highlighted at a time. What is shown in light and small print in the lower part of the
screen are causes that have already been dealt with (non active causes) [see Figure 9-5].

screen.
