Proceed as follow :
turn the amp off and wait about 3
minutes to make sure that the circuit
ILP
TM
resets
every
parameter.
turn on the amplifier and observe the
return to normal operation with LED ILP
returning
fixed.
if the problem persists (LED always
blinking) contact a service center
EAMLAB.
Note :
it may happen sometimes, after the
intervention of the circuit ILP
TM
, which
is switched on again, the LED or LEDs
come back fixed but the amplifier does
not emit any sound.
This means that the circuit ILP
TM
is
working again and the relay circuit that
releases the load does not detect the DC
component in the output because the
circuit ILP
TM
the block in advance if it
detects abnormalities in the output
stages.
Even in this case, contact the service
center.
Instruction :
In any case, do not ever groped to solve
the problem alone but contact the
service
center.
Any
unauthorized
intervention immediately void the
warranty.
THL
TM
thermal overload
The thermal protection system THL
TM
is
controlled with microprocessor . Thl is
designed
for
maintain
exercise
temperature under 70° Celsius. Activated
only in the case in which the operating
temperature of the final stages exceeds
the threshold of 100 °.
The intervention THL will be signaled by
the fixed LEDs on the front panel (see fig.)
these LEDs will light when the heatsink
temperature reaches 70 ° and the circuit
tries to keep it stable working on current
values and polarization of the power
stages.
When the temperature up 70° to 89° the
led flashing with loop 1 second about .
when temperature up to 90° THL provide
to open output relays and limiting current
on output stage for protecting circuit.
When temperature down to 80° amplifier
realy turn on automatically and amplifier
already for working.
NOTE: if temperature execeed to 100°
Celsius THL turn-off entirely power amp
and
turn
on
automatically
when
temperature return down 70°
Microprocessor for secure and effective
protection :
The CPU control THL , soft start and
entirely power supply for very high
safety working.
