3701/40 ADAPT Machinery Dynamics Monitor Datasheet Bently Nevada Machinery Condition Monitoring Advanced Distributed Architecture Platform Technology - ADAPT The Bently Nevada Advanced Distributed Architecture Platform Technology, or ADAPT 3701, is a family of compact, high performance safety and machinery protection and condition monitoring solutions. ADAPT products are targeted at specific assets and applications, and excel at the intensive signal processing necessary to identify early indicators of machine failure modes long before an alarm. The 3701/40 Machinery Dynamics (MD) Monitor is designed for use on a broad range of machine trains or individual casings where the sensor point count fits the monitor’s channel count and where advanced signal processing is desired. The 3701/40 is optimized for intensive signal processing required on complex machinery such as gearboxes, planetary gearboxes, and roller element bearing (REB) machines as well as offering advanced measurement capabilities on conventional monitoring methods such as radial vibration, thrust position, and casing absolute vibration. The 3701/40 Dual Redundant (DR) monitor is designed for applications that require a higher level of reliability from the vibration system. The 3701/40 has a rugged industrial design allowing it to be skid mounted close to the machine and reduce installation wiring. Its compact size provides more mounting options compared to traditional rack based solutions. It is capable of accepting a wide array of sensor types, including eddy current proximity probes, accelerometers, velocity, acceleration, dynamic pressure, Integrated Circuit Piezoelectric Sensors (IEPE), and magnetic speed pick-ups. The 3701/40 is configured and validated with Bently Nevada Monitor Configuration (BNMC) software. BNMC is a simple and powerful configuration and verification software. It is ordered separately and is required for operation

3701/40 ADAPT Machinery Dynamics Monitor Datasheet protection system that utilizes dual redundant processor modules. The 3701/40 MD Monitor is a self-contained device that is ordered with a single part number for either a simplex or duplex terminal base and is made up of the following major components: In the DR version, each processor module is identically configured and redundantly digitizes and processes all sensor inputs, executes identical logic, and each processor module independently drives separate alarm relays. Quantity Required in each 3701/40 Part 3701 Simplex Terminal Base 3701...

3701/40 ADAPT Machinery Dynamics Monitor Datasheet Processor Module the base but on the opposite side from sensor wiring. The processor module, or CPU module, performs A/D conversion, digital signal processing, alarm and logic processing, and communications to Bently Nevada software and plant automation systems. The CPU module employs sophisticated diagnostics and fault detection processing to enhance reliability, availability, and maintainability of the protection and monitoring system. The processor module is the monitor’s CPU. It is the center of the logic and signal processing for the...

3701/40 ADAPT Machinery Dynamics Monitor Datasheet 3701 Positive (PoV) Input Module Output Modules The 3701 PoV input module is a 6-channel + Keyphasor/speed input module that interfaces to a variety of positively powered sensors such as: +24 V Proximitor sensors, +24 V Interface modules, and 2 wire IEPE sensors using 3.3 mA constant current. 3701 8-Channel Relay Output Module The 3701 8-Ch Relay Output Module provides 8 SPDT relay outputs or 4 "virtual" DPDT outputs and a dedicated Protection Fault relay. Relay logic is user programmable in the BNMC software using the graphical logic...

3701/40 ADAPT Machinery Dynamics Monitor Datasheet l Six discrete inputs (DI) for dedicated dry contact DIs: Trip Multiply, Alarm/Relay Inhibit, Latch Reset, Special Alarm Inhibit, Run Mode, and IP/Account reset. There are two sets of these six inputs on the dual terminal base. l The terminal base also supports one conditioned Keyphasor/Speed output for each processor module and one input. The conditioned I/O is for connecting Keyphasors or Speed signals between two or more 3701 monitors. Terminal Base 3701 Simplex Terminal Bases The term “simplex terminal base” identifies, or distinguishes...
