15 : 6.Metering

The bottom section of the Power Control Manager in-
terface contains a copy of the LED located on the interface
panel (ref. Chapter 12 : 2.Interface board LED
meters that provide a feedback on system performance.

15 : 6.1. LEDs

Ready – When this LED is on the amp is ready and in proper
functioning conditions. When this LED is off the amp is non
functional due to a power fault. This can be either:
f internal: if there is an internal power failure; f
f external: if the amp's load current draw has exceeded
f
the maximum acceptable values set by the current
protection limiters.
E.Save – When this LED is on the amp has entered the en-
ergy save mode, after having detected no input signal for a
selected timespan. The amp's power consumption is mini-
mized by decreasing rails voltage.
Protect – This LED lights when short circuit protection has
acted to prevent amplifier damage. This was caused by the
output current trying to increase above the value set by
the user in the overcurrent protection section. No output is
possible when this LED is on. The amplifier checks every 2
seconds if the short circuit condition is still in place. If not,
the limiting action is interrupted, the LED is turned off and
output is possible again.
Limit – This LED is on every time any limiting action is un-
dertaken by any system limiter.
Temp – When this LED is on, the temperature of the mod-
ule's final stage has gone over the user set limit.
Signal – This LED is on when a signal is detected at the input.
