Product Precautions
Bently Nevada 3500/50M 286566-02 converts up to two proximity-probe or magnetic-pickup signals into configured shaft-speed and direction measurements in a 3500 rack.
- Accepts up to two speed-related transducer signals.
- Supports speed, acceleration, zero-speed and reverse-rotation channel types.
- Provides buffered transducer and proportional recorder outputs.
- Can route conditioned Keyphasor signals through the 3500 backplane.
The module is a machinery monitoring input and must not be used by itself as a speed-control or overspeed-protection system. Events per revolution, thresholds, scaling and alarm delays require controlled configuration.
Important Notice: Verify the paired I/O module, rack slot and channel configuration before replacement. Record peak-value reset, alarm response and host-system indication before release.

Bently Nevada 3500/50M 286566-02 Official Technical Reference Excerpt (PDF)Bently Nevada 3500/50M 286566-02 Installation & Commissioning Guide (PDF)
The first document covers the product function, system role and technical selection. The installation guide covers identification, connection checks, commissioning and the acceptance record.
Shaft-speed monitoring
Measures rotational speed from proximity or magnetic-pickup pulse trains.
Rotor-acceleration alarming
Calculates speed change for configured acceleration channels.
Zero-speed supervision
Detects loss of rotation within the configured channel logic.
Reverse-rotation detection
Counts and reports reverse motion using the selected input arrangement.
Before installing Bently Nevada 3500/50M 286566-02, confirm the documented system, interfaces and controlled configuration.
1
Verify the paired I/O module, rack slot and channel configuration before replacement.
2
Do not use the tachometer module alone for machine speed control or overspeed protection.
3
Confirm transducer type, polarity, amplitude and events-per-revolution before energizing.
4
Set manual or automatic thresholds to suit the installed pickup signal.
5
Verify full scale, alarm delays and recorder-output scaling in the rack configuration.
6
Inspect buffered-output and rear I/O connections for correct channel assignment.
7
Simulate speed, zero-speed and reverse-direction conditions as applicable to the configuration.
8
Record peak-value reset, alarm response and host-system indication before release.
Technical notes
Verify the paired I/O module, rack slot and channel configuration before replacement. Record peak-value reset, alarm response and host-system indication before release.
