Functional Description

3500/62 is a process variable monitor designed and developed by Bently Nevada. The Process Variable Monitor is a 6-channel monitor for processing machine critical parameters such as pressures, flows, temperatures, and levels that require continuous monitoring. The monitor accepts current inputs ranging from +4 to +20 mA as well as proportional voltage inputs ranging from -10 to +10 Vdc. It conditions these signals before comparing them to user-programmable alarm setpoints.

Features

• The component can be programmed to perform current or voltage measurements using the 3500 Rack Configuration Software.
• It includes I/O modules for three different signal input scenarios: +/-10 Volts DC, isolated 4-20 mA, and 4- 20 mA with Intrinsically Safe zener barriers.
• External power input terminals are provided by the Internal Barrier I/O to provide intrinsically safe power to the 4-20 mA transducers. When used in a Triple Modular Redundant (TMR) configuration, you must install Process Variable Monitors adjacent to each other in groups of three.
• The monitor uses two types of voting in this configuration to ensure accurate operation and to avoid loss of machinery protection due to single-point failures.

Functional Description

• Continuously compares monitored parameters to configured alarm setpoints in order to trigger alarms for machinery protection.
• Provides critical machine information to operations and maintenance personnel.

Front Panel LEDs

• OK LED - Indicates that the Process Variable Monitor is in good working order.
• When the Process Variable Monitor is communicating with other modules in the 3500 rack, the TX/RX LED illuminates.
• When the Process Variable is in Bypass Mode, the Bypass LED illuminates.

Alarm Setpoints

• For the value measured by the monitor, the user can set Alert and Danger setpoints.
• Alarms can be set to range from 0 to 100% of full-scale for each measured value. The exception is when the full-scale range exceeds the range of the sensor in which case the setpoint will be limited to the range of the sensor. Alarms are accurate to within 0.13% of the desired value.
• Under and over alarm setpoints are available on the Process Variable Monitor.

Environmental Limits

• Operating Temperature: -30 to +65 degrees Celsius when used with Internal/External Termination I/O Module.
• Operating Temperature: 0 to +65 degrees Celsius when used with Internal Barrier I/O Module (Internal Termination).
• Storage Temperature: 0 to +85 degrees Celsius
• Humidity: 95%, noncondensing.

Rack Space Requirements

• Monitor Module: 1 full-height front slot.
• I/O Modules: 1 full-height rear slot.

FREQUENTLY ASKED QUESTIONS

What is 3500/62?
It is a process variable monitor designed and developed by Bently Nevada.

How can the Process Variable Monitor be programmed?
The Process Variable Monitor can be programmed to perform current or voltage measurements using the 3500 Rack Configuration Software. This software allows users to customize the alarm setpoints and other parameters to meet their specific application needs.

What types of signal inputs does the Process Variable Monitor accept?
The Process Variable Monitor accepts three different signal input scenarios: +/-10 Volts DC, isolated 4-20 mA, and 4-20 mA with Intrinsically Safe zener barriers.

What is the Triple Modular Redundant (TMR) configuration?
The Triple Modular Redundant (TMR) configuration is a type of configuration used in the 3500 rack-based monitoring system to ensure redundancy and reliability. In this configuration, Process Variable Monitors must be installed adjacent to each other in groups of three. The monitor uses two types of voting in this configuration to ensure accurate operation and to avoid loss of machinery protection due to single-point failures.
