Adjust the input range setting the DIP switches 3 and 4 as shown below. Select the desired power-on delay time setting the absolute scale(0.1 to 30s). Setting of delay on alarm time on Setting of upper level on relative scale.Setting of lower level on relative scale. Reservation exceeds the upper set level. The relay releases in case of interruption of one or more phases,when one or more voltages drop below the lower set level or (load monitoring)Example 2 The relay monitors over and under voltage,phase loss and phase sequence. relay releases immediately. Only 200ms delay occurs. The failure is indicated by the red LED flashing 5Hz during alarm status. at 2Hz and the output relay releases after the set delay time. If the phase sequence is wrong or one phase is lost.the output If one or more phase-phase voltage exceeds the upper set level or drops below the lower set level,the red LED starts flashing DPB51 operates when all 3 phases are present at the same time,the phase sequence is correct and the phase-phase voltage levels are within the set limits.
