Description

The Bently Nevada 135785-01 is a non-backlighted display unit designed for providing local or remote visual indication of 3500 Machinery Protection System data residing in the rack. The 135785-01 collects system information via a high-speed internal network, including System Event Lists, Alarm Event Lists, and channel, monitor, relay module, Keyphasor module, or tachometer module data. It utilizes a reflective 640 x 200 dots FSTN dot matrix LCD display without a backlight, requiring ambient white light for visual operation. The unit interfaces with the 3500/93 Display Interface Module (DIM) over an RS422 hardware interface supporting Bently Nevada proprietary protocol and Modbus protocol.

Features

  • Reflective 640 x 200 dots FSTN dot matrix LCD screen displays data in graphical and text formats without backlighting.
  • Provides dedicated visual indication via Unit OK LED, Rack OK LED, Rack Alert LED, Rack Danger LED, New Alarm LED, and 8 individual channel OK, Alert, and Danger status LEDs.
  • Communicates with the Display Interface Module via RS422 hardware interface with 1 second typical channel update rate.
  • Supports Bently Nevada proprietary protocol and Modbus protocol based on AEG PI-MBUS-300 Rev. E Reference Manual.
  • Maximum power consumption of 5.6 watts.

Applications

  • Local or remote visual monitoring of 3500 Machinery Protection System parameters.
  • System Event List and Alarm Event List viewing in API 670 machinery protection systems.
  • Visual alarm and channel status indication across 3500 rack installations.
