Description

The 200350 and 200355 Accelerometers are general

purpose, case-mounted seismic transducers designed

for use with Trendmaster Pro Constant Current Direct

Input Card, part number 149811-02 and the Seismic

Direct Input Card, part number 164746-01.

The 200350 and 200355 Accelerometers are contained

within a hermetically sealed, stainless steel case.  The

design provides an extremely rugged transducer, well

suited for harsh industrial environments.  Each

transducer’s top mounted, 2-pin connector (MIL-C5015) allows for easy installation and removal of the

interconnecting signal cable.  A ¼-28 threaded hole on

the bottom of the casing accommodates multiple

mounting options.

The 200350 and 200355 Accelerometers contain a

piezoelectric sensing device, which generates charge

when subjected to vibration.  This charge is then

converted electronically to a differential voltage signal,

which is proportional to the acceleration that is parallel

to the sensitive axis of the transducer.

Most common machine malfunctions (unbalance,

misalignment, etc.) occur on the rotor and

originate as an increase (or at least a change) in

rotor vibration. For any individual casing

measurement to be effective for overall machine

protection, the system must continually transmit a

significant amount of rotor vibration to the

machine casing, or mounting location of the transducer.

In addition, be careful to install the accelerometer

transducer on the bearing housing or

machine casing.

Description

The 3300/05 rack is a durable, easy to access, expandable mounting medium for

the 3300 Monitoring System. It accommodates a Power Supply, System Monitor,

and various types of 3300 Monitors. Each monitor position in the rack includes a

Signal Input/Relay Module position at the rear of the rack. The rack mainframe is

manufactured in sections from an injection molded plastic; a conductive antistatic

material dissipates electrostatic discharge.

The rack bezel allows you to individually identify machine/monitor points or loop

numbers by using the factory engraved bezel tags or clear plastic strips over

paper tags. The 3300 modular design eliminates the need for internal rack

wiring and allows easy expansion to meet your increased monitoring

requirements.

The left-most position (position 1) of the rack is designated for the Power Supply.

The position next to the Power Supply (position 2) is reserved for the System

Monitor. The other rack positions (3 through 14) are available for any

combination of individual monitors.

Description

The Rack Interface Module (RIM) is the primary interface to the 3500 rack. It

supports a proprietary protocol used to configure the rack and retrieve

machinery information. The RIM must be located in slot 1 of the rack (next to the

power supplies).

The RIM supports compatible Bently Nevada external communications

processors such as TDXnet, TDIX, and DDIX. While the RIM provides certain

functions common to the entire rack, the RIM is not part of the critical monitoring

path and has no effect on the proper, normal operation of the overall monitoring

system. One RIM is required per rack.

For Triple Modular Redundant (TMR) applications, the 3500 System requires a

TMR version of the RIM. In addition to all the standard RIM functions, the TMR RIM

also performs “monitor channel comparison.” The 3500 TMR configuration

implements monitor voting using the setup specified in the monitor options.

Using this method, the TMR RIM continually compares the outputs from three (3)

redundant monitors. If the TMR RIM detects that the information from one of

those monitors is no longer within a configured percentof the information of the

other two monitors, it will flag that the monitor is in error and place an event in

the System Event List.

Description

The 3500/93 System Display is designed to meet the requirements of American

Petroleum Institute (API) Standard 670 and provide local or remote visual

indication of all 3500 Machinery Protection System information residing in the

rack including:

 System Event List

 Alarm Event Lists

 All Channel, Monitor, Relay Module, Keyphasor* Module or Tachometer

Module data

The 3500/93 System Display is configured using 3500 Rack Configuration

Software. The display can be mounted in any of four ways:

1. Face Mounting – display installs directly over the front panel of any full

size 3500 rack using a special hinged support. This permits access to the

rack’s buffered output connectors and user-interface buttons and

switches without disconnecting or disabling the display.

Note: For this mounting option only, the Display Interface Module (DIM)

must be installed in slot 15 (right-most slot) of the rack. The Face

Mounting option is not compatible with the 3500 Mini-rack.

DESCRIPTION

The 3500/33 16-Channel Relay Module is a full-height module that provides 16 relay outputs.

You can place any number of 16-channel relay modules in any of the slots on the right side of the Transient Data Interface (TDI) module.

Each output of the 3500/33 16-channel relay module can be independently programmed to perform voting logic.

Each relay of the module contains alarm drive logic.

The alarm drive logic is programmed using AND www.cniacs.com and OR logic and the following are available:

Alarm inputs (alarms and hazardous states)

Uncertainty states

Individual measurement variables from any monitor channel or any combination of monitor channels in the rack

You can program the alarm driver using the 3500 rack configuration software.

Ordering Considerations

The 3500/33 16-Channel Relay Module requires 3500 Rack Config version 3.3 or higher.

3500/33 requires 3500 Data Acquisition Software version 2.40 or later.

3500/33 16-channel relay modules require 3500 Data Display Software version 1.40 or higher.

If ordered with the Multiple Certification option (02), the 3500 monitor will be certified to Zone 2 standards, including ATEX and North American.

The Zone 2 standard specifies higher spacing requirements at www.cniacs.com higher voltages. 3500/33 16-channel relay modules do not meet these spacing requirements.

Therefore, modules with the multiple certification option can only be used at lower voltages than modules with other certification options.

The use of higher voltages violates the hazardous area certificates associated with the multiple certification options.

The North American Division 2 standard associated with the CSA certification only option (-01) has been reduced to 30 Vrms to comply with 61010-1 type test requirements.

If the 3500/3316 Channel Relay Module is part of a Functional Safety (SIL) system, the Functional Safety Certificate requires voltage limitation.

The Functional Safety Certificate requires voltage limiting. Higher voltages are not permitted for Functional Safety (SIL) systems.

DESCRIPTION

DESCRIPTION

The 3500/25 Enhanced Keying Module is a half-height, two-channel module used to provide keying signals to the monitoring modules on the 3500 rack.

The module receives an input signal from a proximity probe or magnetic pickup and converts the signal to a digital key signal that

to indicate when the key mark on the shaft coincides with the key sensor.

The 3500 Mechanical Protection System accepts up to four Keyphasor signals in a normal configuration and up to eight Keyphasor signals in a paired configuration.

The Enhanced Keyphasor Module is an improved module for the 3500 system. It provides enhanced keyphasor signal processing over the previous design, while at the same time

It remains fully backward compatible in form, fit, www.cniacs.com and function with existing Keyphasor modules for use in legacy systems.

The 149369-01 module completely replaces the PWA 125792-01 Keyphasor module.

When Triple Module Redundancy (TMR) applications require system key inputs, the 3500 system should use two Keyphasor modules.

In this configuration, the modules operate in parallel, providing primary and secondary key signals to other modules in the rack.

Systems with more than four pushbutton inputs can use a

paired configuration, provided that

there are no more than four primary keyed phase input signals.

The paired configuration requires two

Description

The 3500/22M Transient Data Interface (TDI) is the interface between the 3500 Monitoring System and compatible software (System 1 Condition Monitoring and Diagnostics Software and 3500 System Configuration Software).

(System 1 Condition Monitoring and Diagnostics Software and 3500 System Configuration Software).

The TDI combines the functionality of the 3500/20 Rack Interface Module (RIM) with the data collection capabilities of a communications processor such as TDXnet.

The TDI is located in a slot next to the 3500 rack power supply. It interfaces with M-Series monitors (3500/40M, 3500/42M, etc.).

It connects to the M-Series monitors (3500/40M, 3500/42M, etc.) and continuously collects steady-state and transient dynamic (waveform) data and transmits this data to the host software via an Ethernet link.

See the Compatibility section at the end of this document for more information.

The static data collection feature is standard on the TDI.

However, using the optional Channel Enable Disk, the TDI can also capture dynamic and high resolution transient data.

TDI integrates communications processor functionality within the 3500 rack.

While the TDI provides some common www.cniacs.com functionality throughout the rack, it is not part of the critical monitoring path.

It has no impact on the proper functioning of the entire monitoring system for automatic machinery protection.

One TDI or RIM is required per 3500 rack and always occupies slot 1 (next to the power supply).

I/O Module Signal Common Terminal

Both versions of the TDI I/O Module now have a 2-pin connector to connect the signal common to the rack’s single point instrument ground.

The rack’s single point meter ground. When connecting, the selector switch on the Power Input Module (PIM) side must be slid in the direction of the arrow marked “HP”.

Slide in the direction of the arrow marked “HP” to isolate the signal common from the chassis (safety) ground.
