2 specifications are subject to change without notice (06.11.00) dpc01, ppc01 mode of operation connected to the 3 phases (and neutral) dpc01 and ppc01 operate when all 3 phases are present at the same time and the phase sequence is correct. it can be decided whether to moni- tor upper and lower voltage level of each phase or their asymmetry and tolerance. in any case if phase-netural measurement is selected both phase-phase and phase-neutral voltages are monitored. asymmetry is defined as fol- lows: when measuring phase- phase voltages and also as follows: when measuring phase-neu- tral voltages. tolerance is defined as and also as when measuring phase-neu- tral voltages. voltage level monitoring: if one or more phase-phase or phase-neutral voltage exceeds the upper set level or drops below the lower set level, the red led starts flashing 2 hz and the respective output relay releases after the set time period. asymmetry and tolerance monitoring: if one of them exceeds the set level the red led starts flashing 2 hz and the respective output relay releases after the set time period. if the phase sequence is wrong or one phase is lost, both output relays release immediately. only 200 ms delay occurs. the failure is indicated by the red led flashing 5 hz during the alarm condition. example 1 (mains - over and under phase-phase voltage - moni- toring) the relay monitors over and under voltage, phase loss and correct phase sequence. example 2 (starting and operating load - asymmetry and tolerance phase-neutral - monitoring) dpc01 and ppc01 ensure correct starting and operat- ing conditions. they monitor the voltage level, phase sequence (correct direction of the motor rotation) and asymmetry. frequent failures are fuse blowing and incorrect volt- age level. in case of fuse blowing the motor regener- ates a voltage in the inter- rupted phase. these relays detect the failure and react due to excessive imbalance among the phases. power supply overvoltage cat. iii rated operational voltage (iec 60664, iec 60038) through terminals: l1, l2, l3, n (dpc01) 5, 6, 7, 11 (ppc01) m23: 208 to 240 vac 15% 45 to 65 hz m48: 380 to 480 vac 15% 45 to 65 hz rated operational power m48 13 va @ 400 vac, 50 hz m23 13 va @ 230 vac, 50 hz supplied by l2 and l3 supply specifications indication for power supply on led, green alarm on led, red (flashing 2 hz during delay time) output relay on 2 x led, yellow environment (en 60529) degree of protection ip 20 pollution degree 3 (dpc01), 2 (ppc01) operating temperature -20 to 60c, r.h. < 95% @ 475 vac, 65 hz -20 to 50c, r.h. < 95% @ 550 vac, 65 hz storage temperature -30 to 80c, r.h. < 95% housing dimensions din-rail version 45 x 80 x 99.5 mm plug-in version 36 x 80 x 87 mm weight approx. 220 g screw terminals tightening torque max. 0.5 nm acc. to iec 60947 ce-marking ye s general specifications (cont.) max{| ? v ph-ph |} nom. voltage max{| ? v ph-n |} nom. voltage max{|nom. voltage - ? v ph-ph |} nom. voltage max{|nom. voltage - ? v ph-n |} nom. voltage power on delay 1 s 0.5 s or 6 s 0.5 s reaction time incorrect phase sequence or total phase loss < 200 ms voltage level (input signal variation from -20% to +20% or from +20% to -20% of set value) asymmetry level alarm on delay < 200 ms (delay < 0.1 s) alarm off delay < 200 ms (delay < 0.1 s) accuracy (15 min warm-up time) temperature drift 1000 ppm/c delay on alarm 10% on set value 50 ms repeatability 0.5% on full-scale general specifications
