Description

3500/42 138700-01 I/O Module Descriptions

The 3500/42 Proximitor/Seismic Monitor is a four-channel monitor that accepts input from Proximitor and Seismic Transducers and uses this input to drive alarms. The monitor can be programmed using the 3500 Rack Configuration Software to perform any of the following functions: Radial Vibration, Thrust Position, Eccentricity, Differential Expansion, Acceleration, and Velocity.

When shipped from the factory, the 3500/42 is delivered unconfigured. When needed, the 3500/42 can be installed into a 3500 rack and configured to perform the required monitoring function. This lets you stock a single monitor for use as a spare for many different applications.

The Proximitor/Seismic I/O Module receives signals from the transducers and routes the signals to the Proximitor/Seismic Monitor. The I/O module supplies power to the transducers. The I/O module also provides a 4 to 20 mA recorder output for each transducer input channels. Only one I/O module can be installed at any one time and must be installed behind the monitor (in a rack mount or panel mount rack) or above the monitor (in a Bulkhead rack).

The primary purpose of the 3500/42 monitor is to provide

1) machinery protection by continuously comparing current machine vibration against configured alarm setpoints to drive alarms and.

2) essential machine vibration information to both operator and maintenance personnel.

3) Alarm setpoints are configured using the 3500 Rack Configuration Software. Alarm setpoints can be configured for each active proportional value and danger setpoints can be configured for two of the active proportional values.
