Description

For systems that provide shutdown functionality, either through direct wiring of relays or through the communication of measurements the control system uses to trip, consider the following system aspects:While the Orbit 60 system has high availability and high reliability when implemented in either a basic simplex or in more complex redundant deployments, Bently Nevada recommends that all applications of the Orbit 60 system for protection follow the guidelines below:

1. Use relays as the Orbit 60 protection output. 2. Monitor the SIM’s protection Fault Relay to validate that the system is protecting the machine. 3. Use redundant protection processor modules to allow fault tolerance and system repair if a module fails. 4. All elements leading to a protection output should be resident within a single chassis. 5. Use redundant Power Input Modules (PIM) on each each chassis with each PIM wired to separate power supplies using functionally independent external 24 V power sources. 6. Wire sensors on the same location on the shaft to separate input modules (e.g., X probes and Y probes from the same bearing wired to separate input modules).6. API 670 deploymentsThis section describes monitoring and protection of a typical API 670 compressor for definition and discussion purposes.Figure 1: Monitoring and Protection Scheme for Typical API 670 Compressor

 

Single chassis InstallationsFor single chassis installations, including the 3U x 19-inch, the 6U x 19-inch and the 3U x 12-inch chassis, the deployment should include the following recommended components: 1. Two redundant Power Input Modules (PIM) 2. Two redundant, independent 24-V Power Supplies 3. Two redundant Protection Processing Modules (PPM) 4. Electro-Mechanical relay (EMR) (Solid State Relay is also valid, if requested) 5. Connection of protection fault relay 6. Single machine train and protection group per system 7. X and Y vibration sensors from a common bearing wired to separate input modulesMultiple chassis InstallationsDeployment of installations with two or more chassis bridged together should include the components recommended for single chassis installations listed above and: 1. One PPM per chassis, providing redundancy and single point failure tolerance 2. One relay per chassis with one relay channel per module in series to drive trip 3. A Protection fault relay connected to a customer system for notification 4. Triple redundant bridge (BRG) cablesFigure 2: Redundant Monitoring and Protection Scheme Diagram
