User manual CARLO GAVAZZI WM14-96 PROGRAMMING

[. . . ] Insulation: AC power supply, 4kV for 60s between measuring input and power supply and between power supply and RS485, 500V for 60s between measuring input and RS485. Input and power supply and between power supply and RS485. Line termination: by means of external jumper. Digital outputs (only with PG option): number of outputs 2 (one for kWh one for kvarh) Number of pulses: from 0. [. . . ] i THE MAIN MENU FUNCTIONS n_P : new password , change password function. SYS : electrical system, choose the correct electrical system; 3P. I: 3-phase balanced with or without neutral (requires only one voltage input "VL1-N" and one current input "I1)"; 2P: twophase, 1P: single phase. Example: if the primary of the CT being connected is 300kA and the secondary is 5A, the CT ratio corresponds to 60, 0k (obtained from the calculation: 300000/5). : integration time for the calculation of power dmd: select the required value from 1 to 30 minutes. End : to confirm the new selected values press the S key, or press L M to remain in the programming menu. 2 : setup of output 1 / 2, select: EnE : retransmits the value of the active energy "Act" or the reactive one "rEA" by means of pulses. "dP" selects the decimal point. "PuL" selects the number of pulses per kWh/kvarh from 0, 01 to 500. No, to go straight to the settings of the next alarm. YES, to continue the programming of all other parameters relating to the alarm being set: d. TYP : select the alarm type: up (uP) or down (do), in window alarm (in), out window alarm (out). Fun : select the OR or AND function (see the "OR/AND" picture below) out : select the relay to be enabled in case of alarm. The measured variable blinks when an alarm occurs (see figure "G" on the left: VL1, 200V). It's possible to link more than one alarm to the same variable, the first alarm condition will make the variable range blink. the "al" (· ) LED shows the activation of one of the two outputs (relay or open collector output) in case they are selected as alarm. When both digital outputs are installed in the instrument (relay or open collector), it's possible to manage up to 16 alarms that can be linked to output 1 and/or output 2. If "var" or "W are negative, the decimal point on the very right blinks in correspondence with the negative variable (see figure "H" on the left). If the instrument displays a negative power, the relevant energy will not be counted. i SAFETY PRECAUTIONS Carefully read the instruction manual. If the instrument is used in a way which is not specified by the builder, the protection may be impaired. Maintenance: To keep the intrument clean, use a damp cloth; do not use abrasives or solvents. [. . . ] Insulation by means of optocuplers, 4000 VRMS output to measuring inputs, 4000 VRMS output to power supply input. Insulation: (for 1 minute) 4kVACRMS between measuring inputs and power supply.
