Appearance
The 7-inch display panel with the true-color touchscreen provides user interfaces for query,
setting, monitoring, and maintenance.
The indicator on the panel displays operating status of the precision air conditioner. Figure 2-5
shows the location of the indicator. Table 2-2 lists the relationship of the alarm status,
indicator, and buzzer. If critical alarms, major alarms, and warning alarms are generated
simultaneously, the indicator shows the status of the alarm with the highest severity level, and
the buzzer shows the status of the alarm (not confirmed after the alarm generation) with the
highest severity level.
