🔹 Short New Title

SHINKAWA VM-701B | Vibration/Displacement Monitor Module | VM-7 Monitoring System

 

🔹 Product Introduction

The SHINKAWA VM-701B is a vibration and displacement monitor module designed for continuous condition monitoring of critical rotating machinery. It is part of the VM-7 monitoring system and is installed in the dedicated VM-76□B instrument rack.

The module supports up to four vibration/displacement input channels and can monitor different parameters depending on the selected transducer and configuration. Supported applications include shaft vibration, displacement vibration, velocity vibration, acceleration vibration, axial position, and differential expansion monitoring.

The VM-701B provides monitor outputs, recorder outputs, alarm relay contacts, transducer power, and optional phase-marker and analysis functions. With the optional /ALY configuration, measured data can also be processed by the SHINKAWA analysis software environment.

🔹 Main Technical Features

⚙️ Four-channel monitoring
The module accepts up to four vibration/displacement inputs with approximately 50 kΩ input impedance for voltage-type signals.

📡 Multiple transducer types
Depending on configuration, compatible inputs include displacement, velocity, acceleration and other vibration transducers. Voltage input is specified as -10 V to +10 V and current input as 4 to 20 mA.

📊 Recorder outputs
Four recorder outputs are available and can be configured for 1–5 V, 4–20 mA, 0–5 V or 0–10 V signals.

🚨 Alarm monitoring
The module provides six configurable relay outputs. Alarm functions include DANGER, ALERT and NOT-OK conditions.

🔄 Phase marker option
When the /PM1 option is specified, the module supports one phase-marker/tachometer input and can handle rotational speeds up to 60,000 rpm.

🖥️ Analysis option
The /ALY option provides additional analysis functions including waveform, amplitude, phase and rotational-speed information.

 

🔹 Operating Procedure — How to Use

1. 🔍 Check the module
   Confirm the model marking, option codes and physical condition before installation. Pay particular attention to the suffixes such as /PM and /ALY because these options affect available functions.
2. 🧩 Install the module
   Install the VM-701B into a compatible VM-76□B instrument rack. The VM-701B occupies one of the monitor-module slots in the rack.
3. 🔌 Connect the transducers
   Connect the approved vibration or displacement transducers to the correct input terminals. Check signal polarity, shield connection and transducer power requirements before energizing the system.
4. 📈 Configure measurement parameters
   Set the required measurement type, monitoring range, filtering and alarm parameters according to the machinery application.
5. 🚨 Configure alarms
   Set DANGER and ALERT thresholds according to the equipment manufacturer’s protection philosophy and the actual machine operating condition.
6. 🖥️ Connect monitoring software if required
   For systems equipped with the appropriate communication and analysis modules, use the configured SHINKAWA software environment to view measured values and diagnostic information.
7. ✅ Verify operation
   Confirm that all required channels show normal status, recorder outputs are correct, alarm contacts operate correctly and phase-marker signals are detected when the option is installed.

 

🔹 Power-Up Sequence

⚠️ Because the VM-701B is a rack-mounted monitoring module, power should be applied through the compatible VM-7 rack power-supply arrangement rather than directly applying an arbitrary external voltage to the module.

Recommended commissioning sequence:

1. 🔌 Confirm that the rack wiring is complete.
2. 🔌 Confirm the primary power-supply module is installed correctly.
3. 🔌 Confirm the secondary power-supply module if redundant power is being used.
4. 🧩 Confirm the VM-701B is fully seated in its assigned slot.
5. 🔗 Check transducer and signal wiring.
6. ⚡ Energize the VM-7 rack power supply.
7. 💡 Check the VM-701B status indicators.
8. 📊 Confirm each measurement channel.
9. 🚨 Verify alarm and NOT-OK indications.
10. 🏭 Start the rotating machinery only after the monitoring system has reached a normal operating state.

The VM-7 rack provides dedicated primary and secondary power-supply positions, while the VM-701B is installed in the monitor-module positions.

 

🔹 Shutdown Sequence

1. 🏭 Stop the monitored rotating machinery according to the plant operating procedure.
2. 📊 Confirm that vibration and displacement values have returned to the expected shutdown condition.
3. 🚨 Check that no abnormal alarm condition remains.
4. 🖥️ Stop or disconnect the monitoring software if maintenance is required.
5. ⚡ Remove rack power according to the plant’s electrical isolation procedure.
6. 🔧 Wait for the equipment to become electrically safe before removing the VM-701B.
7. 🧤 Use appropriate ESD protection when handling the module outside the rack.

Do not remove the module from an energized rack unless the applicable rack and plant maintenance procedure specifically permits live replacement.

 

🔹 Product Usage Notes

The VM-701B is primarily intended for rotating-machinery condition monitoring rather than general-purpose PLC analog input applications.

Typical monitored equipment includes:

• Steam turbines
• Gas turbines
• Compressors
• Generators
• Pumps
• Large rotating machinery
• Petrochemical process equipment
• Power-generation machinery

The VM-7 system is designed for critical rotating machinery monitoring, and the VM-701B can be configured for multiple vibration and displacement measurement applications.

For vibration monitoring, the specified recommended monitoring ranges include approximately 100–1000 μm, 10–100 mm/s and 1–20 g depending on the selected measurement type. Accuracy is specified as ±1% of full scale at 25°C for the applicable standard measurement conditions.

 

🔹 Common Questions & Answers

Q1: Is VM-701B a standalone vibration monitor?

A: No. It is a rack-mounted monitoring module intended for use within the SHINKAWA VM-7 system. A compatible instrument rack and appropriate power-supply arrangement are required.

Q2: How many channels can one VM-701B monitor?

A: Up to four vibration/displacement input channels are supported.

Q3: Can it measure displacement as well as vibration?

A: Yes. The VM-701B supports both vibration and displacement-related monitoring, depending on the transducer and configuration.

Q4: Does every VM-701B have phase-marker capability?

A: Not necessarily. Phase-marker input is an optional configuration identified by the /PM1 option.

Q5: Does every VM-701B include analysis functions?

A: No. Analysis functions require the appropriate /ALY configuration.

Q6: What is the power consumption?

A: The manufacturer’s specification states less than 15 W for the module.

Q7: What is the operating temperature?

A: The standard operating temperature range is 0°C to +65°C. For the specified explosion-proof construction, the range is 0°C to +60°C.

Q8: What should I check before replacing a VM-701B?

A: Check the complete model number and option suffixes, rack compatibility, transducer type, channel configuration, alarm settings and existing software configuration. A visually similar module with different option codes may not provide the same functions.

Q9: Can an older VM-701 be replaced directly with a VM-701B?

A: Compatibility should be checked at the complete system level. Rack type, wiring, option codes and software version should all be verified before replacement.

Q10: What does the /ALY suffix mean?

A: /ALY indicates the optional analysis function. It enables additional analysis data such as waveform, amplitude, phase and rotational-speed information when the required system configuration is present.
