This software runs under MS-DOS 5.0 version or higher. This program let you configure and display any CVM instrument, as well as the CVMR8 peripheral. It can support up to 12 instruments connected in a network. These instruments are easily accessible from CVM_ST. In the display option we will be able to see all CVM family parameters. 2.0 CVM_ST CONTENTS. CVM_ST is supplied with following items: þ 3.5" , 1.4 Mbyte diskette with CVM_ST program. þ Instruction manual. þ Register card. 3.0 CHARACTERISTICS. CVM_ST allows the centralization of several CVM measurement points at one computer. All the readouts get from CVM are instantaneous, so the communications between instruments and the computer are made in real time. The parameters displayed by the computer can also be stored in the Hard Disk, to export them to other programs as LOTUS, EXCEL,.... 4.0 INSTALLATION. Before installing the program, be sure that your system has the required equipment for a proper operation. The equipment must be the following: MS-DOS 5.0 (or higher) plus one serial communication port (or more). ------------- Software CVM_ST ------------- Pag. 3 Once you have checked the environment, Install program can be executed. Following the computer will install CVM_ST program in your hard disk. + Fill the register card and sent it to us. Once you are registered, you will receive information about new products, updates programs and technical support. 5.0 PERFORMANCE. 5.1 BEGINNING Execute the program CVM_ST. If it is the first time you execute it, a password will be requested, being this password the number 775042 followed by the serial number of the diskette (from 1 to 9999); after a language menu will appear , in which you can select the language you desire. Use arrow keys to choose it and press Enter to validate. Second time you execute the program, language choice will not be required, as it will take by default the last you selected. If you want to change the language, you should delete LING.DAT file, and execute again CVM_ST program. The first time you enter in the CVM_ST program, NET_485.DAT file will not be found, in which network configuration is stored. To advise that the file is not found a message will appear on screen. The file will not exist until you add any instrument in the network . Following, the following options appear: Add CVM and Quit. The first option let you add another instrument in the network (see section 5.2). The possibility to choose the language will depend on the following files: LINGESP.MSG LINGGB.MSG LINGFR.MSG LINGDE.MSG LINGIT.MSG SPANISH ENGLISH FRENCH GERMAN ITALIAN ------------- Software CVM_ST ------------- Pag. 4 5.2 NEW INSTRUMENTS INSTALLATION For a proper installation of new instruments, please follow the next steps: 1.- Physical disconnection of all instruments connected to the network. 2.- Connect only the instrument you want to install. After that, go to Add option and write peripheral number, by default number 00 appears (CVM has 00 number by default, too). Using 00 you can communicate to any CVM, although it has assigned another number, therefor, it is essential to have disconnected the rest of CVMs. Then press Enter to communicate to the instrument. If the action is successful*, it will show the current transformer status, with the messages: Correct, Inverted or There is not current. * CVM_ST will automatically change serial port and baud rate if the communication causes an error.

Note that the value you enter has 4 characters and if you enter 10.000 is to disable the alarm. Example: 300 kW 1.23 kW Correct Correct ------------- Software CVM_ST ------------- 555.32 kW Pag. 15 Error: There are more than 4 characters WARNING: Voltage parameter has another set-up rules: First of all it is necessary to explain that CVM_R8C works with "kV" units, but you enter "V", therefore if CVM_R8C accept 4 characters of "kV" and you enter "V", the range values are the following: -999.900< Volts < +999.900, and 1.000.000 is to disable the alarm. That means that if you enter 10.540 V, the value is accepted because for the CVM_R8C that value is 10,54 kV and it has 4 digits, but if you enter 10.543 V, CVM_R8C takes this value as 10,543 kV and it can not be accepted because it has 5 digits. Delay: It is the time the relay takes to activate. The value range is between 0 and 99 sec. Relay: This shows the relay number we want to activate, for CVM_R8C the possible values are 1 to 8 and if you also have CVM_R10 the values are 1 to 18. To finish, press ESC key. F6 Relays: This option let you validate or invalidate relay status, using arrow keys and pressing enter over the relay you want to set. To finish, press ESC key.

Entering in this section following options are available: · F5 : Diagram · F6 : A/D channels F5 Drawing With this option we enter in the CIR_LD program, which will allow us designing a logical circuit with the addition of relays, timers, meters, etc. Due to the complexity of the program and the necessity of showing some examples, it has been separately edited. ¡WARNING! : F4 Transfer option of CIR_LD program, needs a minmum quantity of memory, if computer does not have enough memory, you should execute Memmaker program from DOS, if still memory is not enough, transfer the automat program through DOS executing CIR_SEND <progname.OBJ>. ------------- Software CVM_ST ------------- Pag. 17 F6 A/D channels and stop/start relays The CVM-R8C peripheral has two A/D channels, where zero and full scale value can be programmed. You place over the data to be modified with the cursor keys, entering directly the value or with the Enter key which edits the data. Values must be within -20.000 and 20.000. Two relays which can be programmed as Normal or Stop/Start are also available. With Enter key the relay type is changed. F1 Save This option send the modifications to the CVM-R8C equipment. Following we pass to the previous menu. ESC Exit With this option we exit the set-up option without any modification. 5.3.9 R8 Power control program. Power control program allows the regulation of the power at any installation, keeping the power consumption below a certain value. In case that the trend is to exceed the prefixed limit, the P.L.C. will order the disconnection of loads as per the previously set up priority. The program works with sliding window system. Entering in this section following set up parameters are available: · Parameter to be controlled (Active P. or Apparent P.). · Maximeter power. · Integration period. ------------- Software CVM_ST ------------- Pag. 18 · Hysteresis margin. · Disconnection priority of the relays. Parameter to be controlled This parameters refers to the power type we want to control. Pressing Enter when we are over this option a menu with two options (Active power or Apparent power) is shown up. Maximeter power Upper limit in Watts for the power consumption. Integration period Period in minutes of the maximeter, which can be within 1 and 60 minutes. It should be the same as for the electrical utility and, if it is possible, for the CVM. Hysteresis margin It is a zone under the prefixed power where no operation is carried out. It can be programmed from a 0 to a 100 % of the prefixed power. This value will depend on the load size, as the lower the loads are the lower the hysteresis margin must be. Disconnection priority of the relays This data is the disconnection priority chart, from the highest to the lowest. The output relays (between 2 and 8, and between 2 and 18 if R10 peripheral is also connected) will be shown. The 1 output has been fixed as an error alarm (if the communication with the CVM is lost). Relays will be entered with a comma separation and from lower to higher disconnection priority. F1 Save This option send the modifications to the CVM-R8C equipment.
