Maintenance
Error messages
A system message blinks and the STATUS LED is lit in red.
There is a corresponding event message in LA Network Manager (refer to the
LA Network Manager
video
tutorial)
Service message
System Message
Unit service required
Displayed every 1.5 seconds in alternance with an issue's specic error message if
this issue requires urgent maintenance on the amplied controller. The controller must
be sent to an L-Acoustics representative for maintenance.
Mains voltage messages
LA12X is equipped with a universal SMPS (Switched Mode Power Supply) compatible with mains input nominal voltages
of 100 V / 240 V ±10 %. The mains connected to LA12X is monitored for under and over-voltage, refer to section
(p.49).
System Message
Mains overvolt warning
Displayed if mains voltage reaches a value 11 to 20 % above nominal. The
amplied controller remains operational, but mains voltage should be monitored.
System Message
Mains overvolt error
Displayed if mains voltage reaches a value 20 % and more above nominal. The
SMPS reboots. The amplied controller should be connected to a more stable mains
power source.
System Message
Mains peak volt warning
Displayed if mains voltage reaches a peak value of 362 V. The amplied controller
remains operational, but mains voltage should be monitored. If using an electrical
generator, check the sizing, refer to
Planning the power of the electrical generator
(p.18).
System Message
Mains peak volt error
Displayed if mains voltage reaches a peak value of 400 V. The SMPS reboots. The
amplied controller should be connected to a more stable mains power source and/
or mains power source should be checked by a qualied electrician. If using an
electrical generator, check the sizing, refer to
Planning the power of the electrical
(p.18).
System Message
Mains under volt warning
Displayed if mains voltage reaches a value 10 to 20 % below nominal. The
amplied controller remains operational, but mains voltage should be monitored.
System Message
Fuseprotect
Displayed if the mains voltage reaches a value 30 % to 20 % below nominal. The
outputs are muted. Normal operation resumes when mains voltage returns to nominal
state.
System Message
Mains under volt error
Displayed if mains voltage reaches a value of 50 V. The SMPS reboots. The amplied
controller should be connected to a more stable mains power source, the length of
power source cables should be reduced, larger gauge power cables should be used,
or less devices in parallel should be connected to this power line.
Mains frequency messages
LA12X is equipped with a universal SMPS (Switched Mode Power Supply) compatible with mains input nominal
frequency of 50 Hz / 60 Hz. The mains frequency is monitored for under and over-frequency.
System Message
Mains over freq warning
Displayed if mains frequency reaches a value of 65 Hz or above. The amplied
controller remains operational.
System Message
Mains under freq warning
Displayed if mains frequency reaches a value of 44.9 Hz or below. The amplied
controller remains operational.
These messages may be displayed when the power supply (typically a generator) is being challenged by the power
demand of the connected amplied controllers. Suggestion: slightly reduce the audio levels to reduce the power demand.
