Overview The X96S is a family of measurement products that is intended to replace the current X96N and X99 product families. These products: • use nuclear measurement techniques, • support all features of the current X96N and X99 products, • support up to 32 scintillation or ionization detectors, • optional HART interface, • improved user interface options1, • more user functionality, and • more product flexibility.
Basic Concepts Communications The Ronan X96S Level gage provides both 4-20 mA current loop and HART communications. 4-20 MA For many years, the field communication standard for process automation equipment has been a 4-20 mA current loop signal. The current varies in proportion to the process variable being represented. In typical applications, a signal of 4mA will correspond to the lower limit (0%) of the calibrated range and 20mA will correspond to the upper limit (100%) of the calibrated range.
Configuration Variables The Ronan X96S Level gage has many configuration variables that are accessed through its menus.
Theory Theory of Radiation Gaging Radiation gages operate on the principle of radiation absorption and transmission. A beam of gamma radiation is directed from the source holder, through the vessel and its process material, and onto the surface of the detector. Radiation which is not absorbed by the material through which it passes, is transmitted to the surface of the detector. Process measurement is possible because the amount of radiation absorbed and transmitted is predictable.
• Calibration (Referencing) – calibration of gage to user process. The Calibration (or Referencing) procedure relates detector output (in counts) to numeric values that accurately represent the actual process level. The level algorithm used by the X96S software is a simple transfer function.

Installation Caution Specific License General License Ronan's Monitor Systems use a sealed radioactive cesium (Cs-137) source which is safe if handled properly. Most Level Monitors are mounted to large vessels. Installations on vessels that permit personnel access require a specific license. Your company's specific license will name a Radiation Safety Officer (RSO) or Radiation Protection Officer (RPO). The RSO for your company must be notified immediately upon receipt of the gage.
Inspection The source holder is equipped with an ON/OFF mechanism. During shipment and storage the mechanism MUST BE SECURED in the OFF position with a padlock. Radiation Label If the padlock is damaged, broken, or missing, contact the RSO immediately.
Safety Precautions During installation the RSO will provide guidelines to assure safety. Consider the information presented in the Regulation/Safety Chapter of this manual, as well as the following general guidelines: The source holder must remain padlocked in the OFF position until installation is complete. Take all necessary precautions to assure that the source holder is not dropped or damaged.
Mechanical Mounting Review the Configuration Drawing which is included in the Drawing Chapter of this manual. Please reference the dimensional drawings located in he Drawing Chapter of this manual when installing the equipment. Drawings Consider the following general guidelines when mounting the sensor and detector: Avoid internal vessel obstructions such as baffles, agitators, manways, heater/cooler tubes, etc.
Electrical Installation of Interconnect Wiring DO NOT APPLY POWER until wiring is carefully checked. Drawings Drawings: Interconnect Wire the equipment according to the detailed interconnect drawing which is included in the Drawing Chapter of this manual. Follow local and national electrical codes for all interconnections.

Calibration Calibration correlates the X96S's output to your actual process level. It instructs the microprocessor to read and store the detector counts for a low and high level of process. Once the system is conditioned to recognize the low and high level, it will provide a 4-20 mA output over the entire range of interest. Reference Modes One of your first tasks will be to calibrate the system. The first step in the calibration procedure is to "reference" the gage on some known level.
Configuration Ronan ships the Level Monitor System with factory-default software settings. Those settings are responsible for the information that initially appears on the status displays. After installation at your site, you may need to reconfigure the system to fit your application. The goal is to correlate the X96S output with your actual level readings.
Detector Scintillator Detector Description The Ronan scintillation detector consists of three main components: The plastic scintillation n crystal, the photomultiplier tube (PMT), and the associated electronics. Scintillation Crystal The crystal used for the Continuous Level Monitor System is poly vinyl toluene (PVT) plastic. The crystal produces light pulses which are proportional to the incident radiation events striking it.
Detector Service The critical components of the electronic circuit and the PMT/Crystal Assembly are aligned before leaving the factory. If any component of the Scintillation Detector is adjusted or replaced, the performance of the entire system will be adversely affected and will require realignment before continued use is possible. Therefore, the scintillation detector IS NOT field serviceable.
ION Chamber Detector/Amplifier Assembly (DET-7471-XXX) Ronan’s ion chamber detector is filled with an inert high-pressure gas. It uses low-voltage (-15VDC) bias and generates a low-level current proportional to the gamma radiation incident on the detector. The current generated is on the order of 10 ρA, so an electrometer amplifier is required to convert the current to a low-impedance, high level voltage signal.
Servicing the Detector The ion-chamber detector contains pressurized inert gas. The ion chamber itself is not serviceable and must be returned to the factory for service. Instructions follow for “Detector Removal/Replacement.” However, a qualified technician can troubleshoot and service the detector’s amplifier assembly. Instructions follow for that procedure as well. Some precautions are needed when handling the detector/amplifier assembly.
Detector Removal/ Replacement 1) Check NOTES below for illustrations and cautions that apply to your specific equipment. 2) Unscrew cap on detector housing. 3) Unscrew connector on top of detector. 4) Remove detector from housing. 5) Carefully install replacement detector in housing. 6) Screw connector back onto detector.
Removing the Detector Amplifier Circuit Board (CBAY-6102) Follow this procedure to remove the electrometer amplifier circuit board: 1. Remove the amplifier cover by unscrewing the hex socket head cap screws. 2. Remove the MS connector from the amplifier cover. 3. Remove the two 6-32 binding head screws, which secure the amplifier board to the detector. 4. Using a low power (60W) iron unsolder the detector leads to the printed circuit board standoffs.
Replacing the Detector Circuit Board/Connector Assembly Reference: B-6102-K If installing a new electrometer amplifier board, refer to drawing B-6102-K for internal connector wiring and connections to the detectors. Be sure the detector leads are straightened to clear the holes in the new circuit board. Follow this procedure. CAUTION: Excessive twisting or bending can damage the detector leads. 1. Carefully straighten the detector leads to clear the holes in the new circuit board. 2.
