The VM4-96P position monitor is a 4-channel device that receives signals from proximity probes or LVDT probes as inputs, processes these signals to identify displacement position, and compares it against the warning and danger thresholds set by the operator. It then displays the results and activates corresponding output relays. Control and settings for the device can be managed via an input keypad and through communication with a server computer.

The VM4-96P can be programmed for the following applications:

• Shaft axial position

• Differential expansion

• Body expansion

• Control valve position

This monitor features a full-color display output, control key inputs, buffered signal output, warning and danger relay outputs, a 4-20 mA output, and LAN communication for server connectivity. The device’s relays can be programmed for various AND and OR combinations of different channels.

Main Objectives and Applications of the VM4-96P Monitor:

• Machine Protection: Continuous and direct measurement, providing alerts for warning and danger statuses when measurement values reach specified thresholds.

• Information Provision: Supplying necessary shaft position data for operating personnel and maintenance staff.

Features:

• Four Proxy Input Channels: Capable of monitoring multiple points simultaneously.

• Measurement of Axial Motion: Displays the movement status of the shaft within the available space.

• LED Displays: Indicate hazard, warning, and error statuses clearly.

• Buffered Output: Ensures stable signal transmission for further processing.

• Graphical Display: Shows changes over different time periods for better analysis.

• Various Relay Inputs and Outputs: Supports alerts for warning, danger, acknowledgment, and reset.

• Visual and Numerical Representation: Displays current values along with alert and danger thresholds, providing notifications for warning, danger, and error states.

• LED Indicators: Includes LED status lights for alert management, reset, and acknowledgment reactions, as well as LEDs for performance and processing status.

• Trend Display: Shows trends in axial movement over various time intervals, up to one day, directly on the monitor.

• Data Storage: Offers the capability to store this trend data on the server computer for future analysis.
