Programme operation In programme status, digital interface adopt layers structure menu type, meter supply three lines number display (se fig. 5) No.1 line is first layer menu information; No.2 line is second layer menu information; No.
0000 mean automatic cycling display. Each board connect see table 6 0000-0120 is keeing time of LCD back light. 0000 means the backlight keeping ON 1111 means the data clear other value is invalid Wiring type Net 0000 or other value 0000 mean 3P4W system. Other value is mean 3P3W system Voltage trans. ratio PT PT value= PT primary value/ secondary value Current trans.
Choosen transmitter item or Set the full scale close analog value of analog item output (refer to 8.2 analog output) Choose transmitter item's and relative electrical parameter (0-20mA, 4-20mA, 4-12-20mA) For example, set "A0-1" TYPE"0135" UAL"5000", which means A phase current 0-5A corresponds to the transmitter output signal of first loop 4-20mA Note: The above menu is applied to the product with complete functions.
Zero-position blanking of voltage signal (PT secondary value setting) 0500 means the blanking not display below 05V (Zero-position blanking setting) Zero-position blanking of current signal (CT secondary value setting) 0010 means the blanking not display below 0.
