Icons

Device status

The heat exchanger is turned ON and operating
normally.

The heat exchanger is turned OFF.

The heat exchanger is turned ON but enters the critical
state because of any LHX sensor failure.

At least one of the LHX sensor readings has crossed the
upper or lower warning threshold.

NO device is detected on this RS-485 port.

To identify the cause of the critical state, view one of the

following:



The LHX Heat Exchanger section of the Dashboard page. See

Monitoring the Heat Exchanger

(on page 194).



The Auxiliary Ports page. See

Monitoring the Heat Exchanger

(on

page 194).



The Alert States section of the LHX heat exchanger page. See

Alert

States and LHX Event Log

(on page 196).

Alert States and LHX Event Log

When an LHX heat exchanger is physically connected to the EMX
device, a section labeled Alert States appears on its device page. The
Alert States section shows information identifying the LHX sensors that
currently fail.

Tip: The Dashboard and Auxiliary Ports pages also point out failed
sensors. See

Monitoring the Heat Exchanger

(on page 194).

A button labeled Show Event Log is located in the Alert States section.
