Faults and Warnings Overview

Fault or warning conditions are indicated by the LED shown in Figure 6-3 on page 18. As the LED indi-
cates several types of faults or warnings, a brief textual description of the fault or warning is provided on the
LCD display. Section on page 34 details the fault and warning indications that appear on the front panel.
Table 8-1 lists the events that may have triggered each fault or warning condition.

Type Description / Troubleshooting
There is a problem with the analog input; verify signal and connec-
Fault
tions.
No input signal can be identified for any valid unmuted input router.
Fault
Connect an input source, or verify input signals and connections.
The temperature has reached a critical 70
Fault off or take steps to cool the unit immediately; continued operation
cannot be guaranteed.
This fault is relevant only to the LM44 device.
Fault There is a problem with the power supply for the A/D convertors;
analog inputs will not be available. Send the device for service.
The selected digital clock and digital input combination is not
Warning aligned. Verify digital input configuration to ensure all clock settings
match.
The device is no longer able to communicate with the Lake Control-
Warning
ler. Check network connectivity.
There are multiple devices with identical Dante device names;
Warning
change the device name to ensure unique.
The temperature has reached 55
Warning ture and take additional steps to reduce temperature if it continues
to increase.
The Lake Controller is no longer able to communicate with the
Warning
device. Check network connectivity.
The input source has been changed either manually or by automatic
Warning
input priority detection.
An input router is muted; all Modules and outputs sourced from
Mute
this input router will be affected.
A Module Input has been muted. The mute is identified via the
Mute
associated Module Input mute button on the front panel.
A Module Output has been muted. The mute is identified via the
Mute
associated Module Output mute button on the front panel.
A processor mute state has been triggered via GPIO. Change this
Event
setting using the external control device.
