The referenced unit is marked SST-2194-001-P001G. For replacement purposes, the complete model and specification code should be matched with the existing installation.

🔹 Product Datasheet

SHINKAWA identifies VM-5K as a Dual Vibration Monitor and lists it among the VM-5 modules supporting vibration monitoring. The official VM-5 documentation also identifies 4–20 mA DC and 1–5 V DC recorder outputs as standard output options for the series.

🔹 Main Features

📊 Dual Vibration Monitoring
The VM-5K monitors two vibration channels and is intended for rotating-machinery condition monitoring. SHINKAWA’s technical information gives VM-5K with an FK-202F non-contact displacement/vibration transducer as an example combination for relative shaft vibration measurement.

⚙️ Rotating Machinery Protection
It can be used as part of a turbine supervisory instrumentation system for monitoring critical rotating equipment.

📡 System Communication
Rack-mounted VM-5 systems support data communication using Modbus/RTU, allowing monitoring information to be integrated into a wider control or monitoring system.

🖥️ Front-Panel Operation
Settings and status checks can be performed from the monitor front panel without interrupting normal machine operation.

🔍 Self-Diagnostics
The VM-5 system provides sensor fault detection and self-diagnostic functions to help distinguish sensor problems from actual machinery conditions.

📈 RMS Option
The VM-5K can be equipped with an RMS rectification circuit for true RMS vibration measurement.

7. 🔍 Confirm both input channels are healthy.
8. 📊 Verify vibration readings.
9. 🚨 Check alarm status.
10. 📤 Verify analog recorder outputs.
11. 📡 Verify Modbus/RTU communication if used.
12. 🧪 Confirm alarm/trip interfaces.
13. ✅ Continue machine startup after the monitoring system is confirmed normal.

🔹 Shutdown Sequence

1. 🛑 Stop or place the monitored machine in the approved shutdown state.
2. 📊 Record the final vibration values.
3. 🚨 Check active alarms and diagnostics.
4. 📋 Save relevant maintenance information.
5. 🔒 Place the monitoring system into maintenance condition if required.
6. ⚡ Remove power according to the approved procedure.
7. 🔌 Disconnect sensors only after appropriate isolation.
8. 🧤 Use ESD precautions when removing the module.
9. 📦 Store the monitor in an ESD-safe package.

🔹 Product Usage

The VM-5K is primarily used to monitor shaft vibration in rotating machinery.

Typical applications include:

⚡ Steam turbines
🔥 Gas turbines
🛢️ Oil & gas compressors
🏭 Process compressors
💧 Pumps
⚙️ Motors
🔄 Turbine-generator sets
🏗️ Industrial rotating machinery
📈 Turbine Supervisory Instrumentation systems

SHINKAWA states that the VM-5 Series covers monitoring parameters including shaft vibration, axial position, eccentricity, differential expansion, temperature and rotational speed.

🔹 Installation & Configuration Notes

📡 Sensor Selection

The VM-5K should be paired with an appropriate vibration/displacement transducer. SHINKAWA lists FK/VK Series transducers among the sensors used with VM-5 systems.

📏 Shaft Vibration Measurement

For relative shaft vibration, the measurement system uses a non-contact displacement/vibration transducer. SHINKAWA’s example identifies the FK-202F + VM-5K combination for this type of measurement.

🚨 Alarm Settings

Alarm values should be based on the actual machine manufacturer’s limits, commissioning data and approved protection philosophy. Do not copy alarm values from another machine simply because the monitor model is identical.

📤 Analog Output

The VM-5 Series supports recorder outputs including 4–20 mA DC and 1–5 V DC. Optional output configurations are also available.

🔄 RMS Measurement

If the VM-5K has the RMS rectification option installed, it can calculate true RMS values from the vibration waveform.
