1 Specifications and Ordering Information 3500 system overview Function The 3500 system provides continuous, online monitoring suitable for machinery protection applications, and is designed to fully meet the requirements of the American Petroleum Institute's API 670 standard for such systems. It represents Bently Nevada's most capable and flexible system in a traditional rack-based design, and represents numerous features and advantages not provided in other systems. The system 's highly modular design consists of: 3500 /05 Instrument Rack (required). One or two 3500 /15 Power Supplies (required). 3500 /22M Transient Data Interface or 3500 /20 Rack Interface Module (required). One or two 3500 /25 Keyphasor Modules (optional). 3500 Rack Configuration Software (required). One or more 3500 /XX Monitor Modules (required). One or more 3500 /32 Relay Modules or 3500 /34 TMR Relay Modules (optional). One or more 3500 /92 Communication Gateway Modules (optional).

Internal or external intrinsic safety barriers, or galvanic isolators for hazardous area installations (optional). These are described in more detail in the following section and in the individual datasheets for each system component. 162096 Page 1 of 10. FOR REFFERENCE ONLY. system Components Power Supply Rack The 3500 /15 Power Supply can be ordered for ac or dc input power, providing compatibility with voltage sources The full-size 3500 . worldwide. Line noise filters are standard. The 3500 Rack Rack is available in can operate from a single supply, or dual Power Supplies 19 EIA rail-mount, may provide redundancy for situations in which power panel-cutout-mount, interruption cannot be tolerated. and bulkhead-mount Dual supplies reside in the upper versions. The rack and lower positions of the left- provides slots for two most rack slot.

3 Redundant Power Power Supplies and a Supplies can be energized with Rack Interface Module in the left-most rack positions that different voltage sources. For are reserved exclusively for these modules. The remaining example, the primary (bottom). 14 slots in the rack can accommodate any combination of supply can be energized with 120. monitor, display, relay, Keyphasor module, and Vac power while the backup communications gateway modules. All modules plug into (upper) supply can be energized the rack's backplane from an uninterruptible 24 Vdc source. and consist of a main module and an Each Power Supply is individually capable of providing power associated I/O to the entire rack and its modules. When redundant supplies module. The I/O are used, one acts as primary power for the rack while the module installs at other acts as a backup, ready to instantly and automatically the rear of the rack operate as the primary rack supply should the other module for panel-mount fail, without interrupting rack functions.

4 Systems, and above The 3500 /15 Power Supply module has self-monitoring the main module for functions that allow it to determine if all its output voltages bulkhead-mount are within Specifications . The module annunciates this via a systems. green Supply OK LED on the Power Supply's front panel. The rack depth is 349 mm ( inches) and NEMA 4 and 4X weatherproof housings are Rack Interface Module/Transient Data Interface available when required for environmental protection or The Transient Data Interface (TDI) or the Rack Interface when purge air is used. Module (RIM) are the 3500 Rack's primary interfaces to the A mini-rack (12 wide instead of 19 ) is also available and configuration, display, and condition monitoring software. features 7 available monitor slots instead of 14. Like its One TDI or RIM is required for each rack and it resides in the larger counterpart, the left-most slots are reserved for the rack slot immediately adjacent to the Power Supply slot.

5 The Power Supply or Supplies and Rack Interface Module. The TDI and RIM support a proprietary protocol used by the 3500 . mini-rack may be mounted in a panel cutout or, using an Configuration Software to configure the rack and the 3500 . optional adapter plate, on 19 EIA mounting rails. Operator Display Software to retrieve rack data and statuses. Bulkhead mounting is not available. TDI provides a direct interface with Bently Nevada's system 1 machinery management software without the need for an external communications processor. The RIM. requires an external communications processors, such as TDXnet , TDIX, or DDIX to interface to Data Manager . condition monitoring software. The system OK relay1 is located within the TDI/RIM's I/O. module. It is driven by NOT OK conditions within the TDI/RIM itself and within other modules in the rack. The TDI and RIM supply self monitoring functions for themselves and for the rack in addition to those provided by the individual monitor, relay, communications, and other modules.

6 While the TDI and RIM provide certain functions common to the entire rack, neither is part of the critical monitoring path and has no effect on the proper, normal Note: The use of internal barriers adds 74 mm (3 inches) to the rack operation of the overall 3500 system or its machinery depth. The bulkhead-mount version of the rack is 267 mm ( inches) protection functions. deep. Actual dimensions of all rack types can be found in BNC document number 129766. Page 2 of 10. FOR REFFERENCE ONLY. Four front-panel LEDs are provided on the TDI and RIM as Monitors follows: OK Indicates that the Rack Interface Module and its Available monitor types in the I/O modules are operating correctly. 3500 system are summarized in Table 1.

All occurring. monitors are microprocessor- based with digitally TM Indicates when the rack is in the Trip Multiply mode.

Status indications Module does not match the physical configuration of the rack; or that a security for each monitor and channel option condition was not met. are provided with bright, front-panel LEDs, allowing observation without operator interaction for easy and convenient operation. Most monitors provide independent 4. to 20 mA proportional outputs for each channel of the I/O. system configuration is secured by means of a keylock module for connection to strip chart recorders or older switch on the front of the TDI/RIM and two levels of process control systems where a digital interface is not software password protection, preventing unauthorized feasible. Where applicable, the monitor's I/O modules changes or tampering.

8 Both the TDI. provide transducers with appropriate power via short-circuit- and the RIM can be connected to a protected terminals. OK detection routines within each portable computer via a front-panel monitor continuously check the integrity of each transducer serial communications port for local and the associated field wiring. changes to configuration. The RIM can also be permanently connected to a Transducer input signals are buffered and sent to front-panel configuration workstation via a rear coaxial connectors2. Buffered output terminals are also panel serial communications port, or to available upon request on the rear of the TDI/RIM's I/O. a remote computer via an optional module. modem I/O module. TDI permanent system connectivity is accomplished via Ethernet ports. The TDI/RIM. provides a front-panel DIP switch that permits the user to assign a unique rack address when multiple 3500 racks are networked with one another. A TDI/RIM provides a system reset switch on the front panel, allowing the user to clear any latched alarms in the system as well as latched NOT OK conditions.

9 An I/O. module provides a set of rear-panel connections as well, allowing for remote activation of this switch. For Triple Modular Redundant (TMR) applications, the 3500 system requires a TMR version of the TDI/RIM (refer to the TMR section of this datasheet for additional Information ). Notes: 1. Dozens of possible event conditions within the rack can drive the NOT. OK relay. For this reason, it is not intended for use as part of a machinery auto-shutdown circuit and should be used for general annunciation purposes only. Page 3 of 10. FOR REFFERENCE ONLY.
