Page 27 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS Engineering - Choosing a Mounting Method The VC-8000 rack’s flexible design allows the monitoring modules to be installed facing forward (wiring in the front of the cabinet) or facing backward (wiring in the rear of the cabinet). This can be helpful, but also confusing if the correct option is not ordered.
Page 28 Bulkhead Mounting Bulkhead mounting takes full advantage of the VC-8000 rack design. The rack is compact and light. All modules are easily accessible. The bulkhead mount rack, has flush mount brackets installed on the backside of the rack as shown. The mounting-hole pattern for bulkhead mounting is the same as for panel mounting.
Page 29 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS Panel Mounting The panel mounted option is required when mounting the system in an existing cut-out. Bulkhead mounting is preferred if there are not cut-outs. Normally, mounting brackets will be placed so that wiring is from the rear of the cabinet.
Page 30 19” EIA Rack Mounting (rare) This method is possible, but rare because most 19” EIA cabinets mount the equipment to the very front of the cabinet (see below); this does not leave any room for wiring or wiring harnesses. Recessed brackets can be ordered which push the rack several inches into the cabinet, but it is much better to bulkhead mount the rack onto a subpanel in the cabinet rather than mounting to the rails.
Page 31 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS Mounting Hole Drawings For mounting hole drawings please visit the downloads page on the B&K Vibro website. Other Considerations 3.7.1 Mounting the Display Remotely You can mount the touch screen display (like on a door) up to 10 feet (3.0 m) from the rack.
Page 32 3.7.3 3300 or 7200 Replacement The 16 slot VC-8000 rack is the same size as the Bently Nevada 7200 and 3300 series 8 Position rack. VC-8000 Racks will mount in the existing panel cut-outs without modification. When replacing a larger BN 3300 or 2700 rack (10P, 12P, and 14P).
Page 33 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS Engineering - Channel Layout There are certain rules that you should be aware of when planning the channel layout in the VC-8000 rack. These are explained below. Phase Trigger Channels The VC-8000 rack allows for six Phase Trigger channels maximum (16P rack). Phase Trigger channels can only be selected in channel 4 of a UMM installed in slots 4-9.
Page 34 Relay Logic (Group Lines) Although rare, complicated relay logic may exceed the allowable limit for “cross monitor voting”. Cross monitor voting occurs when the logic for the relay channel (i.e. in slot 6) includes signals (i.e. from Slots 4 and 5), as shown in the example below. The VC-8000 architecture provides 16 “group lines”...
Page 35 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS Engineering – CMS Gateway The VC-8000 is perfectly designed to replace existing machinery protection racks (for example BN 3300 or 3500). However, in some cases this is not practical and the VC-8000 will be installed as a gateway for CMS data only.
Page 36 Engineering - Managing and Minimizing Alarms The VC-8000 rack has several features to help you manage alarms. Those familiar with plant control rooms know that many of the alarms are initially questioned (i.e. Is it real?). Faulty wire connections, faulty sensors, and faulty equipment often make false alarms more common than real alarms. The following features (and recommendations) may help to improve the reliability of the alarms coming from the VC-8000 system.
Page 37 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS Use Rack Inhibit for Light Maintenance Activities Rack Inhibit prevents all signal channels from going into alarm. This is very useful when you are doing light troubleshooting at the rack. Rack inhibit is very helpful and is easy to use. It is strongly recommended. The nice thing about Rack Inhibit (when compared to Bypass) is that it does not “turn off”...
Page 38 Trip Multiply Trip Multiply was designed for large machines that pass through critical speeds (resonance) on start- up. It allows “protection” to remain in place but the alarms are temporarily raised to a higher value (i.e. 9 mils instead of 3 mils). In practice, the startup of large critical machines is so closely monitored by plant personnel that Trip Multiply is rarely used.
Page 39 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS 6.9.3 Can I Bypass “the Rack” to Avoid a False Trip? No. No. You cannot bypass “the rack”. The bypass function is often misunderstood. Most of the time the phrase “bypass the rack” means “isolate the rack from external systems”. The rack bypass function is a “self-governing”...
Page 40 Wiring - Power and Grounding RCM Power Strategy Redundancy The (single) RCM accepts two external and independent supplies. The RCM routes the +24 Vdc (from each supply) to the backplane. Each module (UMM, TMM, and SAM) selects the highest in-specification voltage line. As soon as one voltage is removed or drops below the other, all modules seamlessly switch to the alternate source, assuring uninterrupted operation.
Page 41 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS 7.2.2 Input Power Fuse Protection The RCM includes power input fuse protection and reverse wiring protection. The fuse is not replaceable. All other power supply voltages and conditioning circuits are distributed on the SAM and monitoring modules.
Page 42 7.2.5 Using Plant-Wide +24 Vdc Power Occasionally a site will have a main +24 Vdc line that is used by all +24 Vdc devices. In this case a 24 Vdc isolator would be required for the VC-8000 rack. The isolator is needed because the VC-8000 rack power common is the same as the UMM common; and connecting the plant-wide +24 Vdc to the RCM may cause a ground fault.
Page 43 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS Connecting Grounds 7.3.1 System Chassis Ground Connect the chassis ground wire to the chassis terminal at the RCM. Follow electrical codes when selecting wire size, maximum wire length, and maximum earth ground resistance.

The UMM provides power (-24 Vdc) sufficient to power the transmitter. Inside the UMM the 4 to 20 mA current signal passes through a 249-ohm sense resistor to create a -1.0 V to -5.0 V analog signal.
Page 48 8.1.9 Wiring Externally Powered (4-20 mA) Transmitters You can use externally powered transmitters. This includes 4 to 20 mA, 0 to 5 Volts, 1 to 5 Volts, and 0 to -10 Volts. Connect as shown in Figure 8-9 with the transmitter loop (+) connected to SIG and loop (-) connected to COM.

Wire the positive output to the TMM channel B terminal and the negative output to the TMM channel C terminal.
Page 53 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS Wiring - Interfacing to External Systems (DCS) There are many features in the VC-8000 hardware designed specifically to interface to the DCS or other external systems. Some are for sharing information, others allow a measure of control. This section provides some guidelines on how best to use these interfaces.
Page 54 9.1.1 Modbus/TCP Ethernet Port (Also NTP) The DCS NET port on the SAM is for Modbus/TCP. This port is an Ethernet port (10/100baseT, using a standard CAT5 or CAT6 cable with an RJ45 connector). Normally there is only one Modbus client reading data from the rack; but (when needed) Modbus TCP does support multiple clients.
Page 55 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS 9.1.2 Modbus Serial Port (RS-232, RS-422/485) The SAM provides a single RJ45 connector for Modbus serial communication. The RJ-45 port is used for convenience; this connector is not a network port. The serial port can used to connect to RS-232, RS-422 (4-wire), RS-485 (4-wire), and RS-485 (2-wire) Modbus clients.
Page 56 9.1.2.1 RS-422 (4-Wire) Daisy Chain The VC-8000 rack does not support RS-422 daisy chain. If the DCS (Modbus Client) is an RS-422 port, we recommend two viable options. · Use a Modbus Serial (RS-422) to Modbus TCP converter and configure the VC-8000 racks for Modbus TCP.
Page 57 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS Fault (Not OK) Relay The Fault (Not OK) Relay activates whenever machine protection is compromised due to a detected VC-8000 or instrumentation failure such as a sensor going bad (Not OK). When the DCS is connected to the Fault (Not OK) Relay, plant operators can be notified that there is a problem with the machinery protection system.
Page 58 9.2.1 Wiring to the Fault (Not OK) Relay The Fault relay is ‘Normally Energized’. The relay is labelled NC for Normally Closed, ARM for Armature, and NO for Normally Opened. These labels indicate the position of the armature when there is no power applied to the rack (i.e. ARM will be connected to NC.). The Fault (Not OK) relay is a single-pole, double-throw (form C) relay.
Page 59 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS Rack Control Signals (Reset, Inhibit, Trip Multiply, SAI, Bypass) There are six input commands (controls) available on the VC-8000. These functions are described in the table below. Command Description Resets all latched alarms. This control is highly recommended Reset (RST) when using latched alarms in the MPS.
Page 60 9.3.1 RCM Discrete Input Connector There are four discrete control input signals on the RCM: Rack Reset (RST), Rack Inhibit (INH), Rack Trip Multiply (TM), and Rack Special Alarm Inhibit (SAI). These four controls operate at the rack level. For example, if the Inhibit contact is closed, all signal channels in the rack will be inhibited.
Page 61 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS 9.3.3 Modbus Discrete Input Commands Modbus commands can be used to set the Reset, Inhibit, Trip Multiply, or SAI commands at the rack level only; for example, you cannot use Modbus commands to place a “Machine Group”...
Page 62 Buffered Output Connectors 9.4.1 UMM Buffered Output Connector (RJ-45) Each UMM has an RJ-45 connector that provides access to buffered output signals in the UMM. These can serve for temporary or permanent connections. Breakout cable 100431-AA is used to connect the UMM to the back of a patch panel. Users can then connect multi-meters (or other devices) to the front of the patch panel.
Page 63 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS 9.4.2 RCM (Secondary) Buffered Output Connector The RCM buffered output connector provide secondary access to buffered analog signals from all UMM modules. This connector is rarely used and is limited to just 10 ft. (3 m) maximum.
Page 64 9.5.1 4-20 mA Fault Conditions In the event of a sensor fault, the 4 to 20 mA output will drop to bottom scale (4 mA). This value is configurable in the MPS Setup software. A 2 mA clamp option is also available for faulted channels. An output between 20 mA and 24 mA indicates an over-range condition.
Page 65 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS Relay Output Relay outputs from the VC-8000 can be used to drive annunciators (lights, horns), to drive a machine trip circuit, or to connect to a DCS etc. The DCS might use the input for a status indicator on an operator screen (HMI) or to drive a secondary relay.
Page 66 DANGER! Higher contact potentials cause current levels which are extremely dangerous and can lead to injury or even death! The permissible levels of contact potentials are: · Max. 50 Volts in the case of AC voltages. UMM and TMM relay connectors support wire gauges from 16 to 28 AWG. When using ferrules, the maximum wire size is 1 mm (17 AWG).
Page 67 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS 9.7.3 Time Synchronization via NTP (via SAM DCS port) The VC-8000 rack can synchronize its time with a master clock using an NTP server. This connection uses the DCS NET (Modbus TCP) port. To use an NTP server, change the Time Source setting to “NTP (via DCS Port)”.
Page 68 9.7.5 Time Synchronization via Modbus The rack time can also be sent using a Modbus command. The Modbus timestamp value is an epoch timestamp and is the number of “tics” that have elapsed since January 1, 1970 at midnight. In the VC- 8000 one “tic”...

After the initial instance is created, the user can modify the AF database (using OSI Soft PI tools) if needed. 13.2.4 Synchronous Waveforms Synchronous Waveform data collection is configured in terms of the number of samples collected per shaft revolution, evenly spaced in phase.
Page 99 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS 13.3 Waveform Data Collection Triggers Each UMM channel is in an infinite loop of continuously sampling waveforms. The “triggers” described in this section are used by the UMM channel to determine when the sample is to be saved. If the sample is to be saved, the UMM channel stores the waveform until it is polled (queried) for the waveform.
Page 100 13.3.3 I-Factor % (Dynamic Collection Rate (% Change)) The VC-8000 monitor will save a waveform whenever there is a significant change in vibration. The patented I-Factor % allows you to tell the VC-8000 what you consider to be a “significant” or “interesting”...
Page 101 Brüel & Kjaer Vibro │ Instruction Content VC-8000 MPS 13.3.5 Boost Mode In Boost Mode the rack suspends Delta RPM and I-Factor waveform collection, and begins saving all waveforms continuously. It is ideally suited for electric motor start-ups which are measured in seconds rather than minutes. Boost mode channels require five settings (Boost Mode enabled, Phase Trigger association, Delta RPM, High Trigger (RPM), Low Trigger (RPM))
Page 102 13.3.6 Paired Channels (XY) Paired channels will always collect waveforms together. There is no setting in the MPS software for “pairing’ channels together – it happens automatically. For example: If Brg 1X and Brg 1Y are paired, and Brg 1X has a waveform collection triggered (I- Factor), Brg1Y will also have a waveform collection triggered and the waveforms will have the same time stamps.

Page 104 13.4.1.2 Compression Deviation (PI Only) The OSI Soft PI Data Archive uses a “swinging door” algorithm to compress time-series data. The algorithm stores only what is needed to provide an accurate data history. The sensitivity of the algorithm is controlled by the Compression Deviation setting. Compression Deviation should be set at twice the Exception Deviation value.
