2.2.7 REMOTE (TCP/IP) Connector (/T option only)
This is an RJ45 connector SK06 fitted at the rear of the unit. This enables control and monitoring to be
performed using TCP/IP (Transmission Control/Internet Protocol).
This arrangement requires the unit to be assigned a unique Internet Protocol address. When first
connected to the network via its RJ-45 connector, the Amplifier’s TCP/IP adapter will attempt to
acquire an IP address automatically (it’s quite common to have networks configured to use ‘DHCP’,
which provides these addresses on demand). The address to which a device has been assigned can
then be determined and, if required, be overridden with a desired fixed value, using Eddystone
supplied software.
2.3 : SETTING UP PROCEDURES
2.3.1 Fuses
If any problems occur after the Amplifier has been installed and switched on, fuses may need to be
checked and possibly replaced. However, a blown fuse would generally indicate the presence of a
fault, which would need correcting.
The type, function and access to fuses is as follows :
Type
Function
Access
0.75A Hold
RXEF 075
Resettable Fuse
For protection of control circuits.
If fuse goes high impedance, all
front panel displays dim or go out
but the fans continue operating.
The
output
power
level
will
generally fall to below its maximum.
Access to this fuse is not normally
required (fuse is fitted to the Power
Supply Board as (2)FS8)
This fuse will automatically reset if the
mains supply to the Amplifier is
interrupted.
0.75A Hold
RXEF 075
Resettable Fuse
For protection of the +50V dc
output on the rear panel Status
connector SK02.
If this fuse goes high impedance,
any external equipment powered off
this supply will cease operation.
Access to this fuse is not normally
required (fuse is fitted to the Power
Supply Board as (2)FS7).
This fuse will automatically reset if the
externally
supplied
equipment
is
momentarily disconnected or if the
mains supply to the Amplifier is
interrupted.
16A (T) HBC
5x32mm
(¼ x1¼ in) Fuses
Two
For protection of internal dc supply
leads to the high current circuitry
within the four amplifier pallets.
If one or more of these fuses blow,
the associated amplifier pallet(s)’
power level falls to zero causing a
reduction in the overall output
power (generally, the front panel
System Normal led will also go to
red).
Remove top dust cover. Fuses are fitted
in clips, as (2)FS2/4, on the Power
Supply Board at the rear left hand side
immediately behind the two PSU’s.
Ensure that any replacement fuses are
tightly held by the clips.
! CAUTION ! Ensure that the mains
supply is either disconnected or is
switched to ‘off’ at the distribution
board (preferably being locked in that
position).
2.5A Hold
RXEF 250
Resettable Fuse
For protection of fans dc supply
leads.
If fuse goes high impedance, the
fans stop operating but front panel
displays
remain
illuminated.
Eventually the output power will
reduce in level as the heatsink
temperature rises.
Access to this fuse is not normally
required (fuse is fitted to the Power
Supply Board as (2)FS6)
This fuse will automatically reset if the
mains supply to the Amplifier is
interrupted.
