Page 8: Introduction
Introduction Reciprocating compressors can develop devastating faults in a short period of time. Mechanical looseness can deteriorate quickly resulting in catastrophic failure of the compressor. In extreme cases, this can happen in a matter of minutes. Causes of mechanical looseness include: ... -

Page 10: Operating Principles
Operating Principles The RMP is a smart vibration transmitter that contains a piezoelectric accelerometer, high speed true peak detector, and a microprocessor. It operates off standard 24 volt loop power and outputs a 4-20 mA signal that is proportional to the Reciprocating Fault Index (RFI). The RFI is a “hybrid” index as defined below. The RMP looks at data for a period of time equal to the length of the specified Time Window (TW). -
Page 11: Installation
Installation For full equipment protection, one RMP is typically mounted on each compressor cylinder. The RMP is generally mounted to the crosshead or crosshead slipper (distance piece) with its sensing axis perpendicular to piston rod motion. If the compressor does not have a crosshead, it should be mounted to the crankshaft side of the cylinder. Figure 3 –... - Page 12 Step 3: Hand-tighten the sensor/mounting stud to the machine, and then secure the sensor with a torque wrench to the mounting surface by applying the recommended mounting torque (see enclosed specification data sheet for proper mounting torque). It is important to use a torque wrench during this step.
-
Page 13: Wiring
Wiring The RMP operates from a standard 2-wire, 4-20mA loop. If using a loop-powered unit, attach the positive (+) input from the power supply to Pin A on the sensor and the negative (-) input from the power supply to Pin B of the sensor. -
Page 14: Programming Software
Programming Software The RMP can be user-programmed with either of two optional programming kits, Model 600A21 (non-ROHS compliant) or Model 600A35 (ROHS compliant). Both kits include a USB programmer cable/dongle (Model 600A21 kit includes Model 070A89 cable; Model 600A35 kit includes Model 070A103 cable), software (Model EE225) and terminal block/integral cable adapter (Model 042M17). - Page 15 Figure 11 – National Instruments Software License Agreement Figure 12 – Installation Verification Screen Figure 13 – Installation Complete Screen...
- Page 16 After the software completes, the USB driver installer will start automatically. The initial USB installer will look similar to the one below. Figure 14 – WinUSB Driver Installation Screen The drivers will now be properly installed and you should get the following screen. Click “Finish”. The software is now ready to use.

Page 19: Programming Sections
Programming Sections The screen has two sections: Actual 649A01 Settings – This section shows the settings currently programed in the sensor. 649A01 Settings to Write – This section shows the options for programming the sensor. Figure 20 – Typical RMP Screen After Successful Parameter Read Reading and Writing Parameters ... -
Page 20: Parameter Options
Figure 21 – Transferring Actual Settings to Settings to Write Field Parameter Options There are seven parameters (Figure 14) that can be programmed to optimize performance of the RMP. At any point during the programming process, the values can be changed between imperial and metric measurements by clicking the Units dropdown in the top navigation menu and then selecting the appropriate measurement type. -
Page 21: Examples
Examples Example 1: Connect the RMP to computer with the USB programmer cable. Run the program. Be sure the Independent box is NOT checked and type 780 in the RPM box. Note that all of the other parameters are set automatically. -
Page 22: Equipment-Specific Usage Guidelines
Equipment-Specific Usage Guidelines Determine Baseline Vibration using the RMP When impacts occur in a machine, peak acceleration rises well above the vibration baseline. The default shock threshold values (Threshold Level 1 & Threshold Level 2) that are automatically inserted in the Programmer Screen based on the specified RPM assume a typical gas compressor with the sensor mounted as recommended in this manual. -
Page 23: Usage With Piston Pumps And Other Types Of Reciprocating Machinery
Usage with Piston Pumps and Other Types of Reciprocating Machinery Although the RMP software has the ability to calculate suggested parameters based on rotational speed for gas compressors, these values may not be appropriate for use when monitoring piston pumps and other types of reciprocating machinery. - Page 24 run the RMP Software. Use the following guideline to calculate Threshold Level 1 and Threshold Level 2 values. a. If the peak acceleration value measured in step 4 is less than or equal to 10 g, multiply it by 3 and set the Threshold Level 1 equal to it.
