-------------- SUPPLY NETWORK ANALYZER AR5-L ----------- Page nº 4 1.- BASIC INSTRUCTIONS This manual is aimed to familiarize the user with the operation of the CHECK- METER program for the portable analyser model AR5/AR5-L. To get all necessary information about operation instructions and safety warnings of the portable analyzer AR5/AR5-L consult it s instruction manual (code M98151101). The AR5/AR5-L analyzer loaded with the check-meter program permits to check both electronic or mechanic energy meters, either for active and reactive energy totalization. The Check-Meter instrument delivers an appropriate checking mode for each energy meter type. Besides of checking energy meter utility, the analyzer provides the visualization on screen of several electrical parameters to verify the correct connection of the analyzer. Recorded data can be downloaded from the AR5 to a PC and further analyzed by means of the PC software. Recording data process is done by means of an liner memory. That means that once memory is full, no new data is recorded anymore. 1.1.- Checking the contents of your package After receiving the analyzer, please check the following points: a) The delivered material corresponds with your order specifications. b) After unpacking, check that the instrument has not been damaged in transit. c) The standard set includes the following items: 1 cartridge for programming the AR5/AR5-L containing the ordered operation mode program. 1 Instruction Manual. CD containing the PC software update. 1.2.- Safety conditions The manual you hold in your hands contains information and warnings about the AR5/AR5-L that the user should respect in order to guarantee a proper operation of all the instrument functions and keep its safety conditions. 1.3.- Connection instructions Before powering and connecting the analyzer check the following points: a) Supply voltage: Through and external power supplier set. Input mains 80 V a.c. 265 V a.c. / output to AR5/AR5-L 12V d.c. b) Frequency : 45...65 Hz. c) Maximum voltage at the voltage measuring circuit: 500 V a.c. phase-to-neutral 866 V a.c. phase-to-phase

-------------- SUPPLY NETWORK ANALYZER AR5-L ----------- Page nº 5 2.- ANALYZER STARTUP 2.1.- Loading a new program The AR5/AR5-L has an internal memory to save diverse operation mode programs to be used by the user. Before starting this action, check that AR5/AR5-L is supplied through the power supplier set. To load any program, follow these instructions precisely: Turn the AR5/AR5-L off. It is necessary to load a coprocessor that comes in a cartridge to part, and that must settle only in the position of the coprocessor (the last position of the list) Connect the cartridge to the AUX input of the meter. Turn the meter on. Select with the keys [5] & [6] that you want to perform a program loading action (LOAD PROGRAM). Press [ENTER] or wait for a while to confirm this operation. Select the position to save the program into. The AR5/AR5-L will perform a test to check that the cartridge has been properly connected. If an inserted cartridge is detected, then the program will be loaded. Once the loading is completed, reset the meter. If no cartridge was found or a loading mistake occurred, reset the meter and redo the above steps. A cartridge will be only valid for the analyser, which the program was for the first time loaded into. Note on the cartridge the serial number of its related AR5/AR5-L.

-------------- SUPPLY NETWORK ANALYZER AR5-L ----------- Page nº 6 2.2.- Choice of the operation mode program The AR5/AR5-L can hold in memory different operation mode programs. The choice of the program to be used is done when starting the AR5/AR5-L up. Turn the AR5/AR5-L on. A list of available programs will be shown on display. Use keys [5] & [6] to choose the desired program. Press [ENTER] or wait for a while to confirm this operation. CHECK THE SETUP UP!!!! All programs have an independent setup; therefore, must be always checked to ensure a proper operation. For instance, whether the setup is modified at the CHECK-METER program, these modification will not be valid for the ANALYSER program, and so for any program. 2.3.- Operation instructions The AR5/AR5-L is a programmable instrument so offering diverse operation modes which can be selected from the available programming menus (0 PROGRAMMING THE AR5/AR5-L). Please read carefully the paragraphs involving STARTING UP (2.-) AND PROGRAMMING THE AR5/AR5-L (5) in order to select the most suitable operation mode for your requirements. If the instrument is not used according to manufacturer s specifications, the protection of the instrument can be damaged.

This is accessible from the screen of instantaneous values (Section 5.1.-) Check Set-up. This is accessible from the screen of energy meter check (Section 5.6.-). 5.1.- Set-up of Instantaneous Values To accessing AR5/AR5-L setup options press the key [SET], on the instantaneous values screen The analyzer will then inquiry for a password that consists of a key sequence to be pressed (the user has 15 seconds to press this sequence). If the default password has not been modified, then the following key sequence must be followed: PASSWORD [3] [SET] [5] [SET] Standard Password Once this password is entered, the analyzer will permit the user to modify any Setup parameters. All programs have an independent setup, therefore, the setup must be always check to ensure a proper operation, since any modification will only affect the active operation program.

-------------- SUPPLY NETWORK ANALYZER AR5-L ----------- Page nº 12 Diverse setting MENUS are available: SETUP DISPLAY FILES CLEAR OFF LANGUAGE INITIAL MENU Select one option with keys [6] & [5]. To access any menu option use [8] or [ENTER]. To close the menu press [3] or [ESC]. If this key is used when only the main menu is open, this is closed. If any modification over any setup parameter was done, before closing a confirmation of setup change is requested on display.

For this arrangement 3 current clamps must be used. 1Φ: To measure Single-phase systems. 5.1.2.2.- PT/CT : Transformation ratios Voltage and current transformation ratios setting. The program will sequentially inquire for following data: PRIM. V: Voltage transformer primary value. SEC. V: Voltage transformer secondary value. PRIM. I: Current transformer primary / Current clamp primary, used for measuring the line currents. NOTE 1 : If voltage is directly measured (no voltage transformer is used), you must set PRIM.V = 1/SECV.V = 1. NOTE 2 : PRIM. I --> This option permits to program: a) The ratio of the Current clamp to be used. b) In case of a high voltage system, the measurement will be carried out through the secondary of current transformers. A shunt ATS-III 5 A a.c./ 2 V a.c. or CP5 clamp will be then required to enter the measurement signal into the AR5/AR5-L analyzer (Never directly connect the 5 A signal to the AR5/AR5-L.). For this case, the C.T. primary must be set at the primary value of the C.T. used for measuring purposes. Ratio set must be modified for each Current or transformer type change to avoid measurement mistakes. Standard clamps give a voltage output (generally 2 a.c. at full-scale). NOTE : Secondary is always set at 2 V a.c. (it is not user-programmable). 5.1.3.- COMM: Communication parameters Program here the parameters of the built-in RS-232 serial output.

Note that with the instrument powered on, the terminals could be dangerous to touching, and cover opening or elements removal actions may allow accessing dangerous parts. The analyser has been designed and tested to meet IEC 348 standard and is factory-shipped in proper conditions. 11.- MAINTENANCE The AR5/AR5-L does not require any special maintenance. No adjustment, maintenance or repairing actions should be done over the instrument open and, should those are essential, high-qualified operators must perform them. Before any adjustment, replacement, maintenance or repairing operation is carried out, the instrument must be disconnected from any power supply source. When any protection failure is suspected to exist, the instrument must be immediately put out of service. The own instrument design permits a quick replacement in case of damage. 12.- TECHNICAL SERVICE For any inquiry about the instrument operation mode or in case of malfunction, you can contact CIRCUTOR s technical service.
