Control Surfaces
Argo S & Argo Q control surfaces have
2 x IEC AC 100–240V AC mains inputs,
powering up to 4 sections. Including
redundancy PSU's.
The AC power inlets which are placed in
the first section and positioned between
the two ZN6578 Surface Power Supply
Unit modules within the same section as
shown in Fig 3 on the previous page.
The AC inlets are wired to connector
plugs which are plugged into the Mains
sockets of the 2 PSU's within each
section which provide AC/DC power
redundancy.
Each Power supply has an AC input
socket and an AC output socket which
allows the AC power to be distributed by
"daisy chaining" the PSU's with plug and
socket power cables.

SURFACE POWER - AC IN
Fig 1 below shows 3 sections each of
which contains dual power supplies for
AC system redundancy with the AC
inputs, fed from each of the two mains
sources.
The power system is designed to cascade
up to 4 x 12 fader sections in a single
chassis. This typically would provide up to
48 standard faders.
Note: the frame is designed to support
up to 8 sections any consoles with more
than 4 sections requires an extra Mains
Input section as shown in Fig 3 on the
previous page.
Other than the ZN6578 power supplies
all the hardware in the control surface
is DC powered via the UN6539 Section
processor's DC outputs which are
distributed on 4 way connectors.
The lower area of Fig 1 shows that the
12V DC outputs from each of the PSU's
are connected to the DC Power inputs of
the UN6539 section processor which has
2 x DC inputs one fed from each PSU in
the section for DC system redundancy.
To ensure all equipment is powered and
redundancy is applied where available,
both IEC inputs to the control surface
need to be fed with 100–240V AC.
If only one of the first two inputs is
fed, System Status error messages will
be generated indicating they are not
receiving power on both inputs.
It is recommended that these two mains
inputs are fed from two separate AC
supplies where possible to provide
redundancy against external power failure.
