1 VC-8000 Machinery Protection System
The VIBROCONTROL 8000, or VC-8000 is a versatile API 670, ISO 10816 and ISO 7919 compliant
machinery protection system consisting of the following components:
•VC-8000 rack, 3 sizes with different mounting options.
•Rack Connection Module (RCM)
•System Access Module (SAM)
•Universal Monitoring Module (UMM)
•Temperature Monitoring Module (TMM)
•Touch Screen Display Panel (optional)
There are many advantages with the VC-8000, starting with the architecture of the system which is
designed to simplify your installation and sustaining costs as much as possible. For example:
No I/O Modules, Compact Design
The rack was designed to save space. The 8 slots (8P) version of the rack (our most popular) is only
9.1’ (H) x 11.0’ (W) x 11.5’ (D) [230 mm (H) x 279 mm (L) x 217 mm (D)]. Yet it can easily handle
most machines with up to 24 channels available.
Integrated Relay, Phase, Modbus and Display
The VC-8000 does not require separate cards for Phase Trigger, Relay Channels, Modbus or local
Display. This saves up to four slots per rack and allows a smaller size rack to be used for many
machines.
Only 4 Spare Cards for Your Entire Site (that’s it!)
A single UMM handles every channel type and external interfaces. For example, Phase, Differential
Expansion, Radial Vibration, Relay Logic, and Analog Outputs.
Only four spares are needed for your entire site (RCM, SAM, UMM, TMM).
Simple Configuration Interface
The VC-8000 Rack Setup software uses a grid based interface, making it easy to see the
relationships between channels and configure your system.

1.1 Rack Chassis
The VC-8000 rack provides flexibility in mounting and arranging monitors modules. The rack is
available in three sizes:
•• 16 slots, full size rack (19”)
•• 8 slots, half-sized rack (most popular)
•• 4 slots, compact rack
All rack sizes support panel, bulkhead, and weatherproof box mounting. The 19” full size rack also
supports mounting in a 19” EIA enclosure.
There is an optional locking door to prevent tampering with wiring and network lines. The rack can
also be ordered with a touchscreen display.
The rack supports 1 to 15 Monitoring Modules depending on rack size and number of System Access
Modules. UMMs and TMMs will operate correctly when installed into any slot other than the first slot
which is reserved for the RCM.

1.2 Four Basic Cards for the VC-8000
There are only four basic cards for the VC-8000 Machinery Protection System.
•RCM: Rack Connection Module
•SAM: System Access Module
•UMM: Universal Monitoring Module
•TMM: Temperature Monitoring Module

1.2.1 Rack Connection Module (RCM)
The Rack Connection Module (RCM) installs
in slot 1 and provides rack power
connections and other rack level interfaces.
•Primary power input
•Secondary power input
•Discrete contact control inputs
•Rack Fault Relay
•Reset button
•LED indictors
•Buffered transducer outputs
1.2.1.1 Redundant Power Supplies
The VC-8000 rack requires +24 Vdc external
power to operate. Redundant power inputs
are provided.
Plant +24 Vdc power can also be used.
IMPORTANT
+24Vdc COM is not isolated from the
Signal COM (in the UMM).
When using plant power (+24 Vdc), a
24V to 24V isolator is necessary.
Refer to the datasheets for information on
external power supply hardware, input
voltage tolerance, and current requirements.

1.2.2 System Access Module (eSAM or bSAM)
The System Access Module (SAM) installs
in slot 2 of the rack, it provides data to
external systems and simplifies
configuration of the rack. There are two
versions of the SAM; The basic SAM
(bSAM) and the enhanced SAM (eSAM).
bSAM
•Configuration of all modules
•Rack system and alarm event lists
•Modbus data
eSAM (preferred)
•All bSAM functionality
•Remote configuration and display
•CMS-SD
•CMS-HD
•CMS-XC
•CMS-PI
•Local touch panel display
eSAM features are a la carte and must be
selected (licensed) when ordering.
The serial Modbus links for the SAM include
RS-232, RS-422, and RS-485. The Serial
Modbus port uses an RJ-45 connector for
convenience, but it is not an Ethernet port.
Redundant Modbus is accomplished using a
primary SAM in slot 2 and a secondary SAM
in slot 3.
A SAM is not mandatory. Both slot 2 and
slot 3 support monitoring modules if a SAM
is not installed. All UMM/TMM monitoring
and alarming functions are independent of
the SAM. However, without a SAM in the
rack, all modules must be configured
independently.
The bSAM and the eSAM use the same
faceplate and look the same. Use VC-8000
maintenance software to verify which SAM
(and licenses) that you have installed (see
section 23.10).
