3300-3说明书

Part Number 141524-01

Rev. F (04/07)

Description

The System Monitor performs four important tasks in a 3300 monitor rack, providing:

Functions common to all monitors in the rack, such as:

- Alarm setpoint adjustment

- Keyphasor ® power, termination, conditioning, and distribution - Alarm acknowledgement

Connection of all installed monitors to an external communications processor (sold separately) via STATIC and DYNAMIC data ports.

Optional Serial Data Interface (SDI) for communication of transducer and monitor data to process computers, digital/distributed control systems, programmable controllers, and other control and automation systems.

Optional Dynamic Data Interface (DDI) for communication of transducer and monitor data to compatible Bently Nevada machinery management software. Depending on the type of data required, this option may eliminate the need for an external communications processor.

Warning

A transducer field wiring failure, monitor failure, or loss of primary power can cause loss of machinery protection. This could result in property damage and/or bodily injury. Therefore, we strongly recommend connection of an external (operator control panel mounted) annunciator to the OK Relay terminals.

Physical

Rack Space

Requirements:

One rack position, installs only in

position two (next to the Power

Supply).

Weight:

0.9 kg (2.2 lbs.). Communications

Protocol:

Either Modicon Modbus® or

Allen-Bradley DF1 protocol (switch

selectable); RS422 or RS232

cabling (jumper-selectable). Data

available via this interface

includes the following on a per

channel basis:

Proportional value for each

monitored variable (available as

current values and a Fast Trend

file)

Proportional value for probe gap

voltage (for proximity probe

channels)

OK status

Alert and Danger alarm status

Bypass status (channel and

monitor)

Trip Multiply status (rack)

Monitor alarm setpoints (Modicon

Modbus only)

Address Setting:

Eight jumpers on the Serial Data

Interface allow setting of up to

256 different addresses.

Baud Rate:

Four jumpers are used to set the

desired baud rate for serial

communications; 19.2 k baud,

maximum.

Message

Checking:

One jumper selects between

Cyclic Redundancy Check (CRC)

and Block Character Checking

(BCC) for message validation.

Allen-Bradley protocol can use

CRC or BCC checking; Modicon

Modbus uses only CRC checking. Parity and Stop

Bit Selection:

Two jumpers allow selection of

parity and stop bit modes.

Specifications and Ordering InformationBCD Switch:

If set, the data returned in Allen-

Bradley protocol is formatted in

Binary Coded Decimal.

Data Format:

Up to 12-bit data is supported;

depends on monitor type.

Data Accuracy:

Data accuracy is the same as the

monitor (no additional losses). Dynamic Data Interface

Communications

Protocol:

Proprietary protocol for

communications with compatible

Bently Nevada computerized

monitoring systems. Connection

to computer is via RS422 (or

RS232 for rack closest to

computer). Data available via this

interface includes the following

on a per channel basis:

Proportional value for each

monitored variable available as

current values and a Fast Trend

file

Proportional value for probe gap

voltage (for proximity probe

channels)

OK status

Alert and Danger alarm status

Bypass status (channel and

monitor)

Trip Multiply status (rack)

Digitized dynamic waveform (time

domain) signals

Address Setting:

Uses the same eight jumpers on

the SDI.

Baud Rate:

Jumper-selectable; 38.k baud,

maximum.

Data Types:

All 3300 monitor types are

supported by DDI. Various types

of proportional data are obtained,

depending on monitor type,

including overall values, individual

channel alarm status, channel OK

status, probe gap (for proximity

probe based monitors), 1X and 2X

amplitude and phase (for vector

monitors).

Accuracy:

12-bit dynamic data is

maintained with no losses. While

DDI can support up to 24-bits of

resolution on static data, the

actual resolution is a function of

the monitor type for each

channel.

Dynamic Data:

12-bit dynamic data is obtained

2-channels at a time from all

3300 monitors which have

dynamic data.

Dynamic Data

Sampling -

Asynchronous:

Sampling rate is selected at the

host computer (Configuration

program); maximum rate is 12.8

kHz for maximum frequency

display (spectrum) of 5 kHz;

resolution 400 lines. Synchronous:

Sampling rate is fixed and is a

function of Keyphasor frequency

(shaft rotative speed). Maximum

Keyphasor frequency is 30,000

cpm (500 Hz). Dynamic data

signal is sampled 32 times per

shaft revolution (32X) for 8

revolutions; maximum frequency

12.5X, minimum 0.125X;

resolution 100 lines.

Trend Data:

Specifications and Ordering InformationSupports both a Trend and Fast

Trend for all proportional data. System Ok Relay

One hermetically sealed, normally

energized, single-pole double-

throw relay is used for

annunciation of a NOT OK

condition in the monitoring rack

and/or a problem with the

primary (mains) power to the rack. Contact Ratings
