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 indicates
several types of faults or warnings, a brief textual description of the fault or warning is provided on the LCD
display. Section on page 21 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.
LCD Text Event Log Text Type Description / Troubleshooting
ANALOG IN
FAULT Frame Fault:
Analog Input
Fault
There is a problem with the analog input. Verify signal and connec-
tions.
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.
FAN FAULT
Frame Fault: Fan
error
Fault
There is a problem with the fan on the device. To avoid overheating,
identify and fix the problem immediately.
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.
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.
PROTECTIVE
MUTE Protective mute
