  • Page 5: For Safety

    FOR SAFETY In this manual, important safety instructions are specially marked as shown below. To prevent the risk of death or injury to persons and severe damage to the unit or peripheral equipment, make sure that all instructions are fully understood and observed.
  • Page 6 WARNING Sample fluid danger prevention When toxic sample fluid comes into contact with any part of the human body or when toxic gases generated by the sample fluid are breathed, there is a danger of severe injury or death. When sample fluid comes into contact with other objects in the vicinity, there is a risk of fire, explosion, corrosion, deformation or other effects.
  • Page 7 Before and after measurement, clean the entire sample fluid system thoroughly to remove any remnants. Otherwise unwanted effects such as thermal build-up, hardening, particle accumulation etc. can occur. This is especially important to prevent the possibility of serious accidents when using the unit to measure different types of sample fluids.
  • Page 9 WARNING The unit uses a laser source This unit is designated as a class 1 laser product according to IEC 60825-1 (2001). The internal particle detector mechanism uses a laser, but it is fully shielded so that the beam cannot exit from the enclosure.
  • Page 10 Warning Labels The following types of warning labels are used with this unit. Warning label for sample fluid and handling INLET and OUTLET The label specifies the maximum sample fluid pressure as 300 kPa (gauge pressure). The label is affixed to the front panel of the unit.
  • Page 11 Laser product warning label (Class 3B) Indicates that the unit internally uses a laser classified as a class 3B laser product according to IEC 60825-1 (2001). The laser source can cause blindness if viewed directly, and can cause skin injuries if the skin is exposed directly to the beam.
  • Page 13 Precautions Operate the unit only as described in this manual. Do not touch any parts of the unit other than necessary for operation. Before using the unit, make sure that all cable and PFA tube connections are correctly and safely established. In case of malfunction, do not attempt any repairs.

  • Page 17: Outline

    Outline The KS-16F is designed to be used as an in-line sensor in a system for measuring the size and number of particles in liquid, using the light-scattering method. Measurement results are output via a built-in interface. The KS-16F consists of the sensor unit and the power supply unit.

  • Page 18: Laser Source Service Life

    Outline Laser source service life The life expectancy of a laser diode such as used in the KS-16F is shorter than that of other semiconductors. When the laser diode nears the end of its service life, the light output falls below the rated level. There are considerable differences in service life between individual diodes.

  • Page 19: Particle Size Detection

    Outline Particle size detection The unit is calibrated at the factory, using particles of known diameter and refractive index (single polystyrene latex spheres with a refractive index of 1.6) in pure water. As the amount of scattered light by such particles is used as reference to determine the particle size, the measured size corresponds to the light-scattering size of polystyrene latex particles.

  • Page 20: Measurement System Configuration Example

    For details on how to perform measurement control and how to read measurement results etc., please refer to the section "Serial Interface" on page 23. It is also possible to configure a multi-point monitoring system using the Rion multi-point interface. For details, please refer to the section "Multi-point Monitoring System"...

  • Page 27: Connecting The Sampling Tubes

    Preparations Connecting the sampling tubes 1. Remove the end plugs from the INLET and OUTLET connectors of the KS-16F by turning the plugs counterclockwise. Important Store the end plugs in a safe place, since they will be needed when the unit is sent to the supplier for servicing and maintenance.

  • Page 28: Removing The Sampling Tubes

    Preparations 3. Slide the tip of the sampling tube onto the INLET connector and turn the nut clockwise to fasten the tube. Connect the OUTLET side in the same way. Removing the sampling tubes 1. Purge the unit with pure water to remove any sample fluid remnants. If the use of pure water poses the risk of sample fluid reaction and thermal build-up, hardening, or particle accumulation, use a different cleaning agent that is suitable for the sample fluid, and finally purge with clean...
  • Page 29 Preparations 3. Place the end plugs on the INLET and OUTLET connectors and secure the plugs by turning them clockwise (see above illustration). 4. Insert the plug of the sampling tube into the flared section at the tip of the sampling tube and turn the nut clockwise to secure it. Important The flared section will contract slightly over time.

  • Page 30: Purge Gas

    Preparations Purge gas In the cases listed below, the interior of the unit should be cleaned with purge gas supplied to the PURGE inlet, to prevent problems such as moisture condensation or adverse effects on the electrical circuitry. If the temperature of the sample fluid is lower than the ambient temperature, so that moisture condensation may occur in the particle detector.

  • Page 31: Before Supplying The Sample Fluid

    Observe the pressure limits for the sample fluid system. The cell and INLET and OUTLET of the KS-16F are made of synthetic quartz and PFA. Never use sample fluids such as hydrofluoric acid which can cause corrosion of fluid-contacting parts. Otherwise leaks or seepage may occur.

  • Page 32: Transfer Rate/Node Address Setting

    Preparations Transfer rate/node address setting Before turning the unit on, set the transfer rate and the node address as described below. The switch bank for these settings is located on the rear panel. Note The setting of the transfer rate/node address setting switch bank is read only when the unit is turned on.

  • Page 33: Turning The System On

    Preparations Turning the system on Important Before turning the system on, make sure that the internal piping is completely filled with sample fluid. If the interior of the cell is dry, the laser beam may burn contamination into the cell lining, causing an increase in noise.

  • Page 34: Measurement

    For details, please refer to the documentation of the external equipment. Measurement procedure The KS-16F can perform a single measurement under control of commands (measurement start/stop/cancel) sent from a computer or similar equipment. This is called the manual measurement mode.
  • Page 35 Measurement Stopping the measurement The measurement can be prematurely stopped in one of the following ways. Measurement cancel command is received ("G2" via serial interface) Initialization command is received ("C" via serial interface) Light source off command is received ("L0" via serial interface) Cover is opened If the measurement is canceled in one of the above ways, no measurement result data will be available (measurement result message is not sent).

  • Page 36: Maintenance

    Maintenance Steps after use When removing the KS-16F from the measurement system, observe the following points. 1. Clean the piping with pure water. For more information, please refer to the section "System configuration example for cleaning" on page 2. Set the POWER switch to OFF and disconnect the power cord from the AC outlet.
  • Page 37 Maintenance 3. Cleaning with cleaning fluid Use pressurization or suction within the prescribed range to pass cleaning fluid through the system. Flow rate control is not necessary. After an ample amount of cleaning fluid has been passed through the system, check the CELL indicator. Suitable cleaning fluid : Optical cleaning fluid, acetone, alcohol or similar Required equipment...

  • Page 38: When The Fuse Has Blown

    The fuse is contained in the FUSE holder on the rear panel. Open the holder by turning it counterclockwise and remove the fuse. Caution Before replacing the fuse, turn off the power at the KS-16F and the power supply unit KZ-50 and disconnect the DC cable that links the KS-16F to the KZ-50. Important Replace the fuse only with the supplied spare fuse.

  • Page 39: Serial Interface
