Product Overview

The Yokogawa UR1000 Industrial Recorder is a dedicated industrial recording instrument for monitoring and documenting process measurements over time. It is suited to plant instrumentation applications where operators need a local record of changing process conditions for operation review, troubleshooting, and maintenance analysis.

The UR1000 can be used in process equipment, production lines, utility systems, and other industrial measurement points where continuous recording is required. By retaining process trends rather than only displaying instantaneous values, it gives maintenance and operations personnel additional information when investigating process changes or abnormal operating conditions.

• Supports troubleshooting by providing historical measurement information.
• Can work alongside PLC and DCS-based control systems.
• Suitable for manufacturing, utilities, and general process instrumentation.

Working Principle

The UR1000 receives measurement signals from connected field instruments and processes the incoming information for indication and recording. As the field measurement changes, the recorder follows the corresponding signal variation and maintains a record of the process trend.

In a typical instrumentation loop, a sensor or transmitter measures a process variable and sends the measurement signal to the recorder. The UR1000 processes the incoming signal and records its change over time, allowing operators to review the behavior of the monitored process rather than relying only on a momentary measurement.

The recorder operates mainly at the measurement and recording layer of the control architecture. A PLC or DCS can continue to handle control logic, sequencing, alarms, and interlocks while the recorder provides a dedicated process recording function.

Installation and Maintenance

1. Panel Installation: Install the recorder in the designated instrumentation panel with sufficient access for wiring, operation, and maintenance.
2. Signal Identification: Confirm the source and purpose of each measurement signal before connecting field wiring.
3. Terminal Wiring: Verify terminal assignments and ensure that measurement connections are properly secured.
4. Signal Verification: Compare the indicated measurement with the expected field condition during commissioning.
5. Grounding: Follow the plant instrumentation grounding arrangement and maintain appropriate separation between measurement and power wiring.
6. Noise Prevention: Route measurement wiring away from motor cables, inverter wiring, contactors, and other potential interference sources.
7. Configuration Check: Verify that the recorder configuration corresponds to the connected measurement system before normal operation.
8. Trend Verification: Review the recorded trend after startup to identify unexpected fluctuations or signal interruptions.
9. Terminal Inspection: Periodically inspect terminals and wiring for looseness, oxidation, or mechanical damage.
10. Environmental Inspection: Keep the installation environment within applicable operating conditions and protect the recorder from excessive dust, moisture, vibration, and heat.
11. Fault Diagnosis: If an abnormal measurement occurs, check the process condition, field instrument, wiring, terminals, and configuration before replacing the recorder.
12. Replacement Procedure: Document the existing wiring and configuration before replacement so that the new recorder can be commissioned without unnecessary changes to the measurement loop.

Technical FAQs

What is the primary function of the Yokogawa UR1000?

The UR1000 is used for industrial process measurement recording. It allows operators to monitor process information and maintain a record of measurement changes for operational review, documentation, and troubleshooting.

Can the UR1000 be used together with a PLC or DCS?

Yes. The recorder can operate alongside a PLC or DCS. The PLC or DCS can perform control, sequencing, alarm, and interlock functions while the recorder provides a dedicated process recording function.

What should be checked if the recorded process trend is abnormal?

First check the actual process condition, followed by the field sensor or transmitter, signal wiring, terminal connections, and recorder configuration. Comparing the measurement with another available instrument can help determine whether the problem originates in the process or measurement loop.

Why is historical process recording useful?

Historical recording allows operators and maintenance personnel to review how a process variable changed over time. This can help identify gradual drift, intermittent abnormalities, operating cycles, and changes associated with equipment operation.
