  • Overvoltage control at any phase from 240V to 295V (switch, 10 positions)
  • Undervoltage control at any phase from 165V to 220V (switch, 10 positions)
  • Control of alternation phases
  • Control of break phases
  • Control of "stiking" phases
  • Operation delay from 0,1 to 10s
 
PURPOSE OF THE RELAY
 Relay control voltage RKN-3-15-15 is designed to control the availability, "sticking" and order of alternation of phases in three-phase circuits of voltage in net with neutral, and for the control of undervoltage and overvoltage above and below the set threshold.
 
DESIGN OF THE RELAY
 Relay is produced in a plastic case with a unified front connection wires power and switched circuits. Mounting is carried out on a DIN rail  width 35mm (GOST R IEC 60715-2003) or on a smooth surface. To set on a smooth surface, you need to push locks. Terminal design provides robust clamp wires up to 2,5mm2. On the front panel there are two switches to set upper "Uphase>" and lower "Uphase<" thresholds, regulator of actuation time "t", two red indicators of net error "U>", "U<",  yellow indicator of built-in executive relay "", three red indicators of availability phases "L1", "L2", "L3".
 
OPERATION OF THE RELAY
 The relay is powered by controlled net. For this you need to connect three controlled phases to terminals L1, L2, L3, neutral wire to terminal N.
 
 WARNING: A connection the neutral wire to terminal N is must!
 
 Upper "Uphase>" and lower "Uphase<" thresholds are setting by using potentiometers, that located on the front panel. A delay of actuation relay is exhibited by medium potentiometer. When power is applied, if a delay is setted and all controlled parameters are normal, the relay will turn on at the end of the counting delay time t, and relay contacts 11-12, 21-22 will be open and contacts 11-14, 21-24 will be close. A flashing indicator "" signals about the counting time delay actuation at which the end of it the buil-in relay switches. At a deviation of one of the parameters of the nominal value, turn on the indication of error and relay switches off after the end of delay. Upon returning the controlled parameter to normal, the indication of error is switched off immediately, and the relay switches after the end of actuation delay. At loss of all three phases a relay turns off without counting delay of actuation time set the user.
 
 WARNING: In violation an order of alternation phases the is a brief alternating turning on indicators «U>», «U<».
 
 Status of indicators «L1», «L2», «L3»:
  • In case of availability of all phases all three indicators turns on
  • In the absence of any phase will turn off  the appropriate indicator «L1», «L2», «L3».
  • When the neutral wire breaks, indicators «L1», «L2», «L3» have little noticeable glow and indicators «U>», «U<», «» is turned off.
  • When you connect the neutral wire to one of the terminals «L» for connection of phase, and phase to terminal «N», turns off the appropriate indicator «L1», «L2», «L3», indicators «U>», «U <» will be turned on.

 Detecting the neutral break in the net is carried out by evaluating phase asymmetry. For symmetrical loading of the three phases the neutral break can not be detected, as soon as the neutral star point under asymmetric load three-phase net will shift, will change the phase voltage inputs on the relay, the neutral break will be detected.
