Features:
- Carries the CN country-approval ordering option
- Distinguishes channel alarms from monitor-health states
- Provides measurement access locally and over Ethernet
The complete Bently Nevada 2300/20-CN number combines the two-channel monitor platform with the country-specific approval option for China.
Two synchronized vibration channels and one separate speed input feed display, alarm and relay processing without merging their signal paths.
Approval marking, certificate scope and installation conditions must be checked against the CN configuration rather than inferred from another 2300/20 suffix.
The Bently Nevada 2300/20-CN Two-Channel Vibration Monitor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Keeping the CN configuration identifiable
- Suffix position: CN occupies the country-approval position in the complete monitor ordering number.
- Nameplate check: Installed approval markings should agree with the documentation supplied for 2300/20-CN.
- Variant boundary: The CN option must not be replaced by the 00 no-approval configuration without a new suitability review.
- Site record: Record the complete part number so certification information remains tied to the installed unit.
Reading operating states without confusing their causes
- Protection Fault: This state shows that a condition can affect protection decisions rather than merely reporting high vibration.
- User Inhibit: The indication identifies intentional inhibition selected by the user or configuration.
- Bypass: Bypass is a deliberate operating state and should be cleared through the defined control path.
- Alert and Danger: Channel alarm LEDs identify threshold results separately from monitor-health indications.
Using outputs as parts of separate signal paths
- Current loops: Each configurable 4–20 mA output follows its assigned measurement and full-scale value.
- Relay circuits: Relay operation must be verified in the external circuit because the monitor has no relay-output feedback.
- Buffered signals: Front BNC outputs provide direct access to sensor waveforms for local diagnostics.
- Load boundary: A current-loop load outside the documented range can prevent the expected output signal.
Network and local records serve different checks
- Modbus access: Ethernet carries process variables and monitor information to a compatible Modbus/TCP client.
- Configuration link: Monitor Configuration software is used for channel, alarm and communication settings.
- Alarm history: Compatible System 1 Evolution versions collect trend, waveform and event context.
- Local fallback: The front LCD and indicators remain the first check when network communication is unavailable.
