BACKPLANE CONFIGURATION

The S5000 can be easily reconfigured in the field if requirements change. Typically the
rear backplanes need to be replaced to accommodate a different module loading. If you
obtained the S5000 with no rear backplanes installed, or simply need to replace one
refer to the steps and figure below.

1. Remove AC power connection(s) to the frame by disconnecting the line cord(s).

2. Disconnect all cables from the frame and remove the frame from the rack. DO
NOT attempt to change backplanes with the frame installed!

3. Remove all modules from the affected side of the frame.

4. Remove the screws holding the backplane in place.

5. Gently pull the backplane assembly rearward and out of the frame.

14797 • November 2004 • Backplane Configuration

6. Install the replacement backplane being careful not to damage the copper EMI
gasket or motherboard I/O pins. It helps to line up the I/O pin side of the backplane
first.

7. Install modules, reconnect cabling and apply AC power.

S5000 FRAME DESCRIPTION

The S5000 Signal Management System (part number S5000) consists of a 2 rack unit
(RU) high metal frame assembly that installs in a standard 19” wide equipment rack.
The frame includes a built-in motherboard (EM0328) that provides module
interconnections and a power distribution board (EM0326) for distributing power from
the AC inputs to the power supplies.

A removable front door with built-in cooling fan provides cooling and EMI
suppression. Modules slide into the frame from the front and plug into the backplane
and motherboard. Information about the modules is presented in the individual module
User Guides.

Figure 3 illustrates the S5000 Frame front view (door open), showing the slots for the

slide-in printed circuit modules. The following list of printed circuit modules is keyed

POWER SUPPLY MODULE (PS5000)

The Power Supply module accepts and adjusts automatically to a wide range of AC
input voltages (90-130/180-250 VAC, 50/60 Hz). Regulators on the module rectify the
AC to produce +/- 7 and +/- 15 VDC which is distributed to the other modules in the
frame.

Figure 11 shows a block diagram of the Power Supply module. The input stage of the

supply includes an AC power line fuse to protect the equipment and a Power Factor
Correction (PFC) stage, which minimizes harmonics and peak currents on the line.
Following this stage a Switching Regulator produces the required DC voltages. Sharing
diodes on the DC rails allow redundant supplies to connect in parallel with isolation
between the supplies. Power for the cooling fan and the green “power on” indicator
LED comes from the +15 volt rail.

Key features of the power supply are the following:

• Power factor correction

• Auto-ranging; no input voltage selection required

• Fused input

14797 • November 2004 • Power Supply Module (PS5000)

• LED DC power present indicator

• Current, voltage, and power limiting

• Charge dump circuit drains hazardous voltages when the power supply is removed

Power Supply Test Points

There are four test points on the front edge of the power supply modules. When
checking the test points, test both the main and redundant supplies. The approximate
range of voltages that may be expected at these points is listed below. Voltages outside
of listed ranges may indicate a bad power supply module; replace with a known good
module.

COMMUNICATIONS INTERFACE SETUP

The CI5705 can be used to control operation of modules within the S5000 frame. This
is accomplished via communications through a 9-pin D-subminiature connector located
on the back of the unit labeled NTWK EIA-485. Communications to the S5000 must
adhere to the RS-485 or RS-422 communications protocol.

The NTWK EIA-485 connector on the rear of the S5000 utilizes the pinout detailed in
the table which follows.

Computers equipped with only RS-232 communications ports will require an RS-232­to-RS-422/485 converter like the B&B Electronics model #4WSD9R (http://www.bb­elec.com/bb-elec/literature/4WSD9R-3903ds.pdf for more information), or others, to
successfully communicate with the S5000 frame. Carefully check the pinout of the
device you select. If it does not match the above information, an adapter cable may need
to be made.

The CI5705 communications interface needs to have a number of parameters
configured for proper operation when connected to a master controlling device via the
NTWK EIA-485 connector on the rear of the S5000.

Each frame in the system must have its own identity. The identification code is assigned
to the frame using the first three DIP switches (SW1,SW2 and SW3) of S2 located at
the front of the CI5705 card. The following table indicates the settings required for each
Frame ID.

Depending upon the controlling device’s operating parameters, the CI5705 may need to
have its communication speed changed. DIP switches SW4 and SW5 of S2 located at
the front of the CI5705 card are used to set the communication speed as detailed in
Table 6 below-

S5000 SYSTEM THEORY OF OPERATION

See Figure 12. The S5000 frame is a relatively simple system consisting of a metal rack
frame, replaceable I/O backplanes on each side of the back of the frame, a power
distribution board, and a motherboard. A variety of modules may be inserted into the
frame as desired to create a complete signal distribution and processing system.

The I/O backplanes hold the BNC or Phoenix I/O connectors to which the external
input/output cables are connected. The plug-in DA modules are fitted with connectors
that plug into the backplane BNC or Phoenix connectors to carry I/O signals onto and
off of the modules.

A rear motherboard (EM0328) inside the center rear of the frame connects to the I/O
modules and, in the case of video cards, connects directly to processing modules via
connectors at the corner of each module cell. Reference signals, DC power, and other
signals are carried between modules via the motherboard.

A Power Distribution board (EM0326) inside the center rear of the frame connects the
external AC power connectors to the Power Supply modules.

MAINTENANCE

The S5000 does not require any periodic electrical or physical maintenance. You may
want to check the system’s indicators occasionally to ensure that the system is operating
normally and to make sure cooling air flow through the fan in the front of the frame is
unobstructed.

Fuse Replacement

Fuses are located on Power Supply modules. If a problem occurs on a module, the first
thing to do is check the fuses. The following table lists the fuses:

LOCATION FUSE VALUE

Power Supply AC Line Fuse 5 x 20 MM Time-Delay 1.25A

Warning: Dangerous voltages and high temperatures are present on the Power Supply
Card. Take precautions to prevent burns and electric shock: Do not touch exposed
wires, connecting pins, heat sinks, or components. Handle the board by its edges.

TROUBLESHOOTING

Many system troubles are caused by easily-corrected errors, such as poor quality or
missing input or reference signals. Table 9 lists common problems and their solutions in
approximately the most likely order of occurrence. Try troubleshooting the system
yourself, and if you are not successful, call Sigma Electronics Technical Support, as
explained near the front of this manual.

In the event that a problem is caused by a bad circuit board, swapping the bad board
with a replacement circuit board is the quickest solution. If you need to order
replacement boards or other assemblies, call Sigma Electronics Technical Support.

Table 9. System Troubleshooting

SYMPTOM POSSIBLE CAUSES AND SOLUTIONS

System not powering up. Verify that the power cord(s) are plugged into the frame and the AC power

source. Use a voltmeter to verify the presence of power at the AC mains.

One or a few modules not powering
up or not operating properly.

Intermittent or missing signal on
outputs.

Check the DC test points on the front of the Power Supply modules (see Power

Supply Test Points on page 16.)

Check the AC line fuse on the Power Supply module. See Fuse Replacement on

page 22.

Check that the modules are fully seated in the frame.

Check input sources to make sure the signal is in good condition at the point
where it originates.

Check input and output cable continuity while wiggling the cables.

Possible low voltage on Power Supply module. Check Power supply test point
voltages. See Power Supply Test Points on page 16.

Possible bad DA/Processing module. Swap the module with a known good
module.
