Main Power Supply

Operating voltage range: 18 VDC ~ 36 VDC, nominal 24 VDC

Typical operating current: 0.3 A

Built-in reverse polarity protection

Transducer Sensor Power Supply

Two-wire sensor drive: Constant current 3.3 mA ±5%, open-circuit voltage 21~24 VDC

Three-wire proximity sensor power: -24.02 ~ -23.47 VDC, max channel current 15 mA

4–20 mA Analog Output (4 channels)

Signal range: 4 ~ 20 mA

Maximum allowable loop resistance: 600 Ω

External loop supply range: 18 ~ 36 VDC

Relay Contact Output (6 programmable relays)

Resistive AC load: 250 VAC / 5 A

Resistive DC load: 60 VDC / 5 A

Max switching power: 150 VA

Buffered Signal Output

Low-impedance vibration signal output, short-circuit protected, no heavy current load capability

Temperature Inputs

Supports RTD and thermocouple signals; low-level millivolt input without large load current

Digital Control Inputs (Inhibit / Reset)

High impedance input, operating voltage 18~36 VDC, tiny quiescent current

Visual Inspection

Examine the monitor housing, display screen and status indicators for physical damage, dust buildup and overheating marks. Check all terminal blocks, sensor cables and connectors for looseness, oxidation and oil contamination. Confirm the unit is securely mounted on the DIN rail and will not shift under vibration.

Environment Inspection

Make sure the temperature and humidity inside the cabinet meet operating requirements. Keep the surrounding environment away from corrosive gas, excessive dust and strong electromagnetic interference. Prevent direct sunlight from irradiating the display panel.

Power Supply Inspection

Measure the input DC voltage to guarantee it remains within the range of 18–36 VDC. Troubleshoot voltage fluctuation and bad contact issues, and verify the normal operation of reverse polarity protection.

Sensor & Signal Circuit Maintenance

Inspect wiring of proximity probes, accelerometers and RTD sensors. Check shielding and grounding conditions; single-point grounding shall be implemented on the monitor side. Check triaxial connectors to prevent ingress of moisture and dirt.

I/O Channel Inspection

Monitor the operating status and loop resistance of 4–20mA analog output circuits. Check relay output terminals for ablation. Conduct periodic tests on relay actuation and alarm response during equipment shutdown.

Communication & Data Management

Ensure stable data communication with the upper monitoring system. Regularly download event logs, fault records and trend data for anomaly analysis. Back up configuration files of the monitor.

Self-diagnosis Check

Check built-in self-test results through the local keypad or configuration software. Timely resolve sensor failures, signal open circuits and internal hardware alarms.

Cleaning Requirements

Clear surface dust using a dry soft brush. Avoid spraying liquid cleaning agents directly onto the module to prevent circuit corrosion.
