Alarm LEDs
Two alarm LEDs are located on the right of the HCM (see Figure 6). The circular red
LED lights to indicate a critical condition that can result in a system shutdown. The
triangular yellow LED lights to indicate a less severe condition that requires monitoring
or maintenance. Both LEDs can be lit simultaneously.
To deactivate red and yellow alarms, you must clear the condition that caused the
alarm.
