Nomadlink / Ethernet Control And Monitoring Network - Lab.gruppen FP+ Series Operation Manual

Following are short descriptions of standard built-in
FP+ Series protection features:
CPL , (Current Peak Limiter) ensures that the
•
amplifier's output does not exceed the safe
current handling parameters of amplifier com-
ponents.
Temperature protection
•
amplifier will not be damaged by exceeding
thermal limits.
PAL , (Power Average Limiter) limits the maximum
•
average power consumption according to the
power supply and mains-breaker capabilities.
Vhf , (Very High Frequency) protection circuits
•
mute the output of the amplifier when non-
dynamic continuous signals above 10 kHz are
detected.
dC protection ensures destructive DC signals
•
will not appear at the amplifier outputs. If such
conditions occur an internal fuse opens and fault
indication is displayed.
Low-impedance
• (short circuit) protection pro-
vides a fault warning indication and shuts down
the output stage when, for example, an input
signal is present and a malfunctioning cable or
driver is short circuiting the output.
high-impedance
• warning reports an alert when,
at the same time, output signal is high and no
current draw is measured. This situation might
occur when no speakers are connected, or when
a driver is blown.
Low inrush current
•
breaker will not trip when several power
amplifiers are turned on simultaneously.
4.2.5 NomadLink / Ethernet control and
monitoring network
The NomadLink network allows easy setup and
control of FP+ Series power amplifiers and other
devices. The patented network topology provides
automatic detection and addressing of multiple ampli-
fiers, and is controlled from a PC via the optional NLB
60E NomadLink Bridge and Network Controllerp
using standard TCP/IP communication. Phantom
powering through the network cables enables the
software to detect devices that are not currently
turned on or connected to the mains. This ensures
very high reliability and redundancy levels while al-
lowing connected amplifiers to remain on standby
with no power consumption.
ensures that the
ensures that the mains
Cable connections can be daisy-chained for easier
system setup. This also reduces total component
costs, simplifies installation, and makes daily opera-
tion more convenient. There is no need to create
a star topology using many switches as with, for
example, an Ethernet system. Individual amplifier
addresses do not need to be manually entered; you
will automatically know where an individual amplifier
resides in the network.
A daisy chain network loop, in combination with
the automatic addressing of devices, enables
Lab.gruppen's proprietary DeviceControl editor
software to automatically create a precise picture
of all connected devices and their relative position in
the chain. By quickly creating a clear overview of the
entire system configuration, DeviceControl provides
flexible control of very large amplifier systems. Set-up
time is minimized, and critical information is readily
available for monitoring performance and solving
problems during operation.
Via NomadLink, you can monitor all metering data
as well as all faults and warning indications simulta-
neously. NomadLink also allows you to remotely
control power on and power off, as well as engage
Mute and Solo functions on individual channels.
