3 TRODUCTO TO THE KOSOS SERES This cat alogue does not const it ut e a form al agreement. ll information given in this manual is subject to change without notice. The KOSOS SERES brings a new phylosophy in digital panel instrumentation which is expressed by multipurpose, modular-concept devices providing a rich array of basic functions and advanced capabilities. With a fully ODULR DESG, it is possible to implement a wide variety of applications by only adding the adequate options. ntelligence within allows the meter to recognize the options installed and ask for the necessary parameters to properly function within desired margins. The basic instrument without output options omits these data in the program routines. The instrument's CLBRTO is made at the factory eliminating the need for adjustment potentiometers. ny circuit or option that may need any adjust incorporates a memory where calibration parameters are stored, making it possible the optional cards be totally interchangeable without need of any subsequent adjust. Custom COFGURTO for specific applications can be made quickly and easily through five front panel keys, following structured choice menus aided by display prompts at each programming step. Other features of the KOSOS family include : COECTOS via plug-in terminal blocks without screws and CLEP-WGO clips cable retention system.

23 . - Program load cell input Refer to the cell manufacturer's documentation, particularly with respect to the cell sensitivity and supply voltage specifications. s load cell indicator the meter's function is to measure forces (weight, pressure, torque...) which are converted to a millivolts al by a bridge type transducer such as load cell and applied to the input of the meter. The instrument supplies 0V or 5V to feed the transducer as selected by jumper (fig. 5.). These voltages can feed up to cells connected in parallel with 0V or up to 8 cells connected in parallel with 5V without need for an external source (fig. 5.). Example: cells with mv/v sensitivity are parallel connected to the meter input. With an excitation voltage of 0V, the max. voltage generated by the cells is 0mV. n the same case but with an excitation of 5V, the max. voltage generated by the cells is 0mV. Software configuration requires selection of the input range which may be selected high enough for the maximum input al to avoid overloads. There are four ranges: ±5mV, ±0mV, ±60mV and ±00mV Example: f a weighing process gives 0mV to the meter input with maximum load, the best range should be 0mV. BTCH FUCTO Operation by logic input Function nº 0 -BTCH- is deed to be used in batch weighing applications where it is required to read the accumulated total of a product quantity per cycle, or day and to keep count of the number of weighing operations. sensor connected to a logic input with function 0 detects the presence of a weight and pulls low the logic input which makes the instrument add the measured value to the totalizer and increment the batch counter in one unit. The meter keeps in memory the totalizer and the batch count in a power failure or disconnection from the power source. These parameters can be displayed permanently on the second display as selected by the user.

The offset may be used to compensate for a difference that may exist between the temperature under measurement and the temperature read by the sensor. The offset is programmable from -9.9 to with 0.º resolution and from -99 to +99 whith º resolution. Example: The instrument is used to control the temperature of a baking oven, but the sensor is located at a distance from the oven where the temperature is degrees below.

36 .. Scaling When the instrument is configured as a process, load cell or potentiometer indicator, the display must be scaled to fit a particular application. Scaling the display consists of asing a display value to every input value. For linear processes this is accomplished by programming two points -(input,display) and (input,display)-. The line plotted between these points establishes a linear relationship in which any input value produces a unique display value. Reverse operation is accomplished by reversing the display values or the input values (see figure). display display direct input input display display reversed input input The two points should be located near the process limits for the best possible accuracy. For non-linear processes it is possible to set up to 0 pairs input-display. Each two consecutive points are linked by a straigh segment forming all together a curve that represents a non-linear relationship between input and display. The greater the number of points used, the more accurate the measurement will be. The input values must be programmed in always increasing or always decreasing order. Two different display values should not be ased to the same input value. The display values can be programmed in any order. The same display value can be ased to different input values. For input values below the first programmed point, the display follows the slope calculated between points and of the scale. For input values over the last programmed point, the display follows the slope calculated between the last two points of the scale. 6

37 Scaling procedure 0 CnFdSP -SCL- -tech ± np-0 The meter offers two methods to scale the display; SCL (menu ) and tech (menu ). The diagram represents the program routine for the SCL menu, but both routines are the same except that in the tech menu, the input values are denoted by tch in the second display. SCL method The input and display values are programmed manually by the front-panel keys. This method can be used when the transducer gives accurate calibrated known als for each point of the process. ±88888 dsp decp- ± np-0 ± dsp-0 s? points = ± np-0 ± dsp-0 s? points = ± np-n ± dsp-n s? points = n ± np-0 ± dsp-0 points = 0 tech method The input values are taken from the actual input al present at the input connector at each point and the corresponding display values are programmed manually. This method is suitable when the transducer is connected to the process and the process can be brought to the desired conditions while programming. Linearization points The first two scaling points are accessible by entering in the proper scaling menu with the ETER key. The access to program scaling points above is achieved by a press of seconds after programming the parameter dsp-0 in the SCL or tech menus. The subsequent input-display pairs follow one another by successive pressings of ETER. When sufficient number of points have been programmed, the user can exit from the routine and save the programmed data by a press of seconds from the display value of the last point. n normal operation, the non-programmed pairs are missed out from the display calculation. 7

55 .. Display Volume based on Pressure There are several methods to calculate the volume of a fluid in a tank. f a pressure sensor is placed in the bottom of the tank, the display may be scaled to convert the sensor's pressures into liquid height. The Beta- provides different approaches to calculate liquid volume.. For some special regular tank shapes, if you know the mathematical relationship between pressure and volume, it will only be necessary to scale the display by two points. For example, for a cylindric vertical tank, volume is the product of the cylinder base area and the liquid height.. f the tank is irregularly shaped, you can use the linearization feature to readout volume utilizando el método teach y linealización por tramos. The method consists of filling the tank with known amounts of liquid, teach the input and enter the volume at each of the selected points over the height of the tank. The more the number of points used, the more accurate the measurement will be.. third method that offers the instrument to extract volume is to set the automatic volume calculation function. This function can be used when the tank's shape correspond to one of the figures represented at right. utomatic Volume Calculation The instrument has most common tank geometry functions pre-programmed to calculate volume; spherical, horizontal cylinder, horizontal cylinder with spherical ends and conical bottom vertical cylinder.
