Module Core Overview

Bently Nevada’s 3500/60 and 3500/61 temperature modules both have 6-channel temperature monitoring capabilities and are compatible with resistance temperature detectors (RTDs) and thermocouples (TCs) inputs. They can condition input signals and compare them with user programmable alarm thresholds. The core functions of the two are the same, the only difference being that the 3500/61 provides recorder outputs for each of the six channels, while the 3500/60 does not have this function.

The module needs to be set to RTD or TC measurement mode through the 3500 rack configuration software, providing multiple I/O module versions:

RTD/TC non isolated version: can be flexibly configured to receive only TC, only RTD, or a combination of both inputs;

TC Isolation Edition: Equipped with 250Vdc inter channel isolation capability, it can resist external interference.

In the Triple Modular Redundancy (TMR) configuration, three temperature monitors need to be installed adjacent to each other, and the system ensures operational accuracy through two voting mechanisms to avoid single point failures.

Manual Key Operation Guide (Installation, Debugging, and Maintenance)

1. Installation and wiring specifications

The manual specifies the prerequisites for safe installation (such as power-off operation, electrostatic protection) and core steps:

Installation environment requirements: working temperature -25~40 ℃ (some models can be extended to -40~50 ℃), relative humidity 5% -95% (no condensation), altitude ≤ 1000m (reduced capacity is required for use at high altitudes), away from dust, corrosive gases, and strong electromagnetic interference sources;

Wiring points:

The main circuit (input L1/L2/L3, output U/V/W) needs to match the cross-sectional area of the wires (according to the rated current), and install input circuit breakers and reactors (to suppress harmonics, optional);

Shielded wires are required for control circuits (analog I/O, digital I/O, encoder interfaces), with the shielding layer grounded at one end to avoid parallel laying with the main circuit cable (reducing interference);

The safety circuit (STO, emergency stop) needs to be independently wired to ensure that protection is triggered first in case of a fault.

2. Debugging process and parameter configuration

The manual provides standardized debugging steps, suitable for most application scenarios:

Pre power on inspection: Confirm correct wiring (no short circuit, virtual connection), grounding resistance ≤ 4 Ω, parameter reset (default factory settings);

First power on: first turn on the control power supply (check if the panel display is normal), then turn on the main power supply (continue only if there are no fault alarms);

Motor identification: Implement the “motor identification” function (static/dynamic identification optional), the frequency converter automatically reads motor parameters (such as rated power, current, impedance), and optimizes control accuracy;

Core parameter settings: Configure key parameters based on load characteristics (such as control mode P100, rated speed P304, starting torque P640, acceleration/deceleration time P221/P222);

Trial operation: First, jog the motor to test the direction of rotation (to avoid equipment damage caused by reverse rotation), then gradually increase the speed to the rated value, and monitor whether the current and temperature are normal.

3. Fault diagnosis and maintenance

The manual includes a “fault code table” that details the causes and troubleshooting methods of common faults (such as F001 overcurrent, F002 overvoltage, F003 overheating), and provides maintenance recommendations:

Daily maintenance: Clean the heat dissipation channel (dust screen, heat sink) weekly, check the tightness of the wiring terminals monthly, and check the insulation resistance quarterly (main circuit to ground ≥ 1M Ω);

Regularly replace components: cooling fan (with a lifespan of about 2-3 years), electrolytic capacitor (with a lifespan of about 5-8 years, adjusted according to the ambient temperature). The manual specifies the vulnerable part models and replacement steps for different models;

Fault record: The frequency converter can store the last 20 fault information (including fault time, current/voltage/speed at the time of the fault), which can be read through the panel or communication interface to assist in locating the root cause.

The Emerson DeltaV S-series traditional I/O module is a modular input/output subsystem designed specifically for DeltaV distributed control systems (DCS). Its core positioning is to enhance the flexibility, reliability, and installation and operation efficiency of industrial process control. It is suitable for industrial scenarios such as petrochemicals, electricity, and energy that require high environmental adaptability and system stability. It can achieve precise acquisition and output of analog and discrete signals.

Core Features and Advantages

Modular and flexible architecture

Scalable design: A single controller can support up to 8 I/O carriers, with a total of 64 I/O slots. It supports mixing various I/O modules such as analog (AI/AO) and discrete (DI/DO) to meet the signal acquisition and control needs of different scenarios.

On demand configuration: Supports the “on-demand procurement” mode, allowing for the selection of I/O cards, 8-slot carriers, power supplies/controllers, and other components based on the system size. These components can be flexibly added as the system expands, avoiding resource waste.

Efficient installation and maintenance

Tool free installation: The carrier is fixed to the T-shaped DIN rail through a buckle, and the I/O module is directly inserted into the slot without the need for tools; All wiring is completed through carriers and terminal blocks, and there is no need to disconnect on-site wiring when replacing modules, reducing maintenance downtime.

Error proof design: Each I/O module and terminal block is equipped with a dedicated “key positioning” mechanism (two rotatable positioning columns, 6 position combinations), allowing only matching modules to be inserted into the corresponding terminal block to avoid the risk of incorrect installation.

Integrated power supply: The I/O carrier is equipped with a 24V DC bus based on-site power distribution, which is divided into primary/secondary power supplies for odd/even slots. Each slot is independently protected by a fuse, reducing the design of external power supply circuits and ensuring that single card failures do not affect other modules.

Online Expansion and High Availability

Online expansion: Supports adding I/O carriers with power on (directly connected to the right side of existing carriers or installed on other DIN rails through extension cables). The controller automatically detects new carriers and modules and enters them into the configuration database without interrupting existing I/O communication.

1: 1. Redundant backup: 4 types of critical I/O cards (such as 8-channel AI/AO, 32 channel DI/DO) support redundant configuration, and can be automatically recognized as redundant pairs by the system when installed in pairs on redundant terminal blocks. In the event of a fault, the switching can be completed within 2 I/O bus scanning cycles (signal overlap<5ms during analog switching, and digital “first on, then off” to ensure uninterrupted power supply to the device), without the need for additional configuration.

Adaptability to harsh environments

Wide temperature operation: All I/O modules operate within a temperature range of -40~70 ℃ (-40~158 ℉) and can be installed in on-site cabinets to reduce the control room footprint and shorten the length of multi-core cable wiring, thereby lowering costs.

Anti interference and anti-corrosion: Complies with ISA-S71.04-1985 G3 level anti-corrosion standard (using normal coating), anti impact (10g half sine wave, 11ms), anti vibration (1mm peak to peak value at 5-13.2Hz, 0.7g at 13.2-150Hz), suitable for complex electromagnetic and environmental interference in industrial sites.

Plan 3: Equipment for speed monitoring, threshold alarm, and rotor acceleration alarm to prevent sudden increase/decrease in speed (such as turbine overspeed acceleration prevention)

Option 4: Speed monitoring, threshold alarm, and reverse rotation notification for devices that prohibit reverse rotation (such as pump type mechanical anti reverse protection)

2. Featured Features

Keyphasor signal sharing: It can be configured to output conditioned Keyphasor signals to the 3500 rack backplane for use by other monitoring modules (such as vibration monitoring modules), reducing the number of modules in the rack.

Peak holding: Automatically stores the highest forward speed, highest reverse speed, and number of reversals during device operation. The peak can be manually reset for easy fault tracing.

Flexible alarm configuration: Supports two-level alarms (Alarm 1/Alarm 2), and the alarm threshold and delay time can be set by software to avoid false alarms (such as short-term speed fluctuations not triggering alarms).

Technical parameters

1. Input parameters

The module is compatible with two types of sensors, and attention should be paid to the usage restrictions of magneto electric sensors (see “Safety Warning”):

Parameters, specifications, and notes

The input signal source is close to the probe (recommended), and the magneto electric sensor does not support reverse monitoring or zero speed monitoring (the signal edge is unclear at low speeds, making it easy to misjudge)

The input signal range is+10.0V~-24.0V. If the signal exceeds the range, it is limited internally by the module to avoid damage

Input impedance standard: 20k Ω; TMR (Triple Modular Redundancy): 40k Ω; Built in isolation barrier: 7.15k Ω, suitable for different system requirements with different configurations

Minimum input frequency close to the probe: 0.0167Hz (1rpm, 1 pulse/rev); Magnetic electric sensor: 3.3Hz magnetic electric sensor does not support low-speed monitoring

The maximum input frequency of 20kHz corresponds to a maximum speed of 99999rpm (matching the number of pulses per revolution)

Number of pulses per revolution, rotor acceleration/zero speed channel: 1-255 pulses per revolution; Other channels: 0.0039~255 pulses per revolution, suitable for speed measuring gears with different numbers of teeth

2. Output parameters

Covering status indication, signal buffering, recording output, etc., to meet monitoring and data recording requirements:

Output type, specification, and function

Front panel LED OK (normal operation), TX/RX (rack communication), Bypass (bypass mode) intuitively judge the working status of the module

Buffer sensor output with 1 coaxial connector per channel (short circuit, ESD protection) for sensor signal multiplexing (such as simultaneous access to oscilloscope debugging)

The sensor power supply is 24VDC, with a maximum of 40mA per channel to provide power for the proximity probe

The recorder outputs a current signal proportional to the full range, with a resolution of 0.3662 µ A/bit, used for data recording and trend chart drawing. Short circuits do not affect module operation

Current output voltage range 0~+12VDC, load resistance 0~600 Ω, suitable for most industrial recorders

Output update rate of approximately 100ms to ensure real-time performance while avoiding data redundancy

3. Accuracy and alarm parameters

Parameters and specifications

Speed accuracy<100rpm: ± 0.1rpm; 100~10,000rpm：±1rpm； 10000~999999rpm: ± 0.01% true speed

Acceleration accuracy ± 20rpm/min

Alarm threshold range 0~100% full scale (software adjustable)

Alarm delay Alarm 1:1~60 seconds (1-second step); Alarm 2:1~60 seconds (0.1 second step size)

Alarm hysteresis 0.2~2.5V (user selectable to prevent frequent switching of alarms)

Safety Warning and Compliance Certification

1. Critical safety warnings

Prohibited as an overspeed protection system: The module does not have redundant protection and sufficient response speed, and cannot be used alone or as a component for speed control systems or overspeed protection systems (such as turbine overspeed shutdown); Analog output is only used for data recording, plotting, or display, and alarms are only used for alarm notification and do not have safety interlock function.

Limitations of magnetic electric sensors: Magnetic electric sensors cannot be used for reverse rotation monitoring and zero speed monitoring. At low speeds, the sensor output signal has no clear edges, which can cause misjudgment of the rotation direction.

Installation in hazardous areas: I/O modules with isolation barriers must be installed according to the specified drawings (138547, 149243/149244) to ensure compliance with hazardous area certification requirements and avoid safety risks.

Installation and usage precautions

Sensor selection: Reverse monitoring and zero speed monitoring must use proximity probes, and the use of magneto electric sensors is prohibited; During installation, ensure that the clearance between the proximity probe and the speed measuring gear meets the requirements (usually 0.25-1.0mm) to avoid weak or distorted signals.

Wiring specifications: I/O modules with external terminals require separate ordering of external terminal blocks and cables; Different types of I/O modules cannot be mixed (for example, internal and external terminal modules cannot be shared on the same channel).

Installation in hazardous areas: Modules with isolation barriers must be wired according to specified drawings (such as 138547) to ensure effective isolation barriers and avoid safety risks in explosive environments.

Peak reset: After equipment maintenance, it is necessary to manually reset the peak value to maintain data and avoid the influence of old peak values on fault diagnosis.

Software configuration: For the first use, the 3500/01 configuration software needs to be used to set parameters such as the number of pulses per revolution, alarm threshold, delay time, etc., to ensure that they match the actual operating parameters of the equipment (such as the number of teeth on the speed measuring gear).
