8.1 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.

Description / Troubleshooting
ANALOG IN
FAULT
Frame Fault:
Analog Input
Fault
There is a problem with the analog input; verify signal and connec-
tions.
NO INPUT
No Input Source
Fault
No input signal can be identified for any valid unmuted input router.
Connect an input source, or verify input signals and connections.
OVERTEMP
Temp Fault:
DSP area
Fault
The temperature has reached a critical 70
o
C (158
o
F). Turn the unit
off or take steps to cool the unit immediately; continued operation
cannot be guaranteed.
PSU FAULT
Frame Fault:
PSU
Fault
This fault is relevant only to the LM44 device.
There is a problem with the power supply for the A/D convertors;
analog inputs will not be available. Send the device for service.
CLOCK
SLIPPING
AES Clock
Slipping
Warning
The selected digital clock and digital input combination is not
aligned. Verify digital input configuration to ensure all clock settings
match.
CTRL OFFLINE
-
Warning
The device is no longer able to communicate with the Lake Control-
ler. Check network connectivity.
NAME
CONFLICT
Dante device
name conflict
Warning
There are multiple devices with identical Dante device names;
change the device name to ensure unique.
TEMP
WARNING
Temp Warning:
DSP area
Warning
The temperature has reached 55
o
C (131
o
F). Monitor the tempera-
ture and take additional steps to reduce temperature if it continues
to increase.
-
Frame Offline
Warning
The Lake Controller is no longer able to communicate with the
device. Check network connectivity.
-
Sound Source
Changed
Warning
The input source has been changed either manually or by automatic
input priority detection.
IN RTR MUTE
Input Router X
Mute
Mute
An input router is muted; all Modules and outputs sourced from
this input router will be affected.
-
Module Input
Mute
Mute
A Module Input has been muted. The mute is identified via the
associated Module Input mute button on the front panel.
-
Module Output
Mute
Mute
A Module Output has been muted. The mute is identified via the
associated Module Output mute button on the front panel.
PROTECTIVE
MUTE
Protective mute
via GPIO
Event
A processor mute state has been triggered via GPIO. Change this
setting using the external control device.
