Emirel V3-01N

TECHNICAL FEATURES AND REGULATIONS VM Max set point. The regulation is made by a trimmer on the front, in % of the nominal voltage (0÷+20%). Vm Min set point. The regulation is made by means of the trimmer on the front in % of the nominal voltage (0÷-20%). T Timer (0,5÷31,5 sec) - The regulation is made by means of the trimmer. It is activated when one of the two set points is overcome. At the end of the set period the output relay changes over. During the time TM the leads AM and Am are flashing. PHASE FAILURE Il V3 01N detects the phase failure basing on the principle that the amplitude and the phase of the “back voltage” are not equal to the phase and the amplitude of the mains voltage. By back voltage it is intended the voltage generated by the motor and appearing on the wire - motor side - after the phase has been interrupted or the wire has broken. VISUALIZATIONS ON GREEN LED: supply on AM, Am RED LED: VM or Vm has been overcome; the led flashes, after the time T the led is ON. L1,2,3 YELLOW LED: it lights on when the phase sequence is L1, L2, L3; it is Off with the different sequence. RESET: automatic. MODE OF OPERATION With the regulations on the front it is possible to fix one set point MAX and one set point MIN in order to have a control band. The set points and the phase sequence (L1, L2, L3) are connected to the same output relay. The output relay is normally on and it goes off when the voltage goes out of the fixed band (both above VM or under Vm), or when the phase sequence is not L1, L2, L3. When the phase sequence is L1, L2, L3, the output relay is ON and the yellow LED is ON. When a phase fails the relay is off; the V3-01N is self supplied from 2 phases, if one on these fails the leds are off or partially turned on (in presence of the “back voltage”); if the 3rd phase fails the yellow led flashes and Am is ON. POSITIVE SAFETY The relay is normally ON and it goes OFF when it is in alarm. INSTALLATION The setup of the thresholds VM and Vm and the tripping time TM are made by trimmers on the front of the device. (Wiring to an electrical board with a differential relay and a sectionalizing switch). The length of every wiring must be less than 30m. INPUT: 5-3-1 (1,2 kW/V) 230Vac / 380Vac / 415Vac. If the pins are not connected in the order L1, L2, L3, the device will be in alarm. It is requested that the pins 5-3- 1 correspond to the phases L1, L2, L3. The YELLOW LED must be ON. OUTPUT: 1 output relay with two change over contacts (5A-230 Vac) resistive load 11-10 / 14-15 NC Device not supplied 11-12 / 14-13 NO or in alarm Insulation between input and contact: VDE 0110 - IGR C/660 Insulation of the contact: VDE 0110 - IGR C/250 SUPPLY (pin 3-5) 2VA - 50÷60 Hz. Self-supplied by the voltage to be monitored. 100/220/230/380/400/415 Vac. RANGES 100 / 220 / 230 / 380 / 400 / 415 Vac. CASE • Self-extinguishing ABS. SIZE: 45x70x110 mm for DIN rail. Accessories available on request: E 405B transparent protection fitted for tight closure. WORKING TEMPERATURE: 0÷70°C WEIGHT: 0,300 kg COLOUR: grey

FUNCTION The voltage relay V3 01N monitors the overvoltage (VM) and the undervoltage (Vm) and the phase sequence L1, L2, L3 in an alternating three phase mains. Adjustment range +20% -20% of the nominal voltage. USE Control of a three phase mains.
