PURPOSE OF THE RELAY
 Time relay starter RVP-3 is designed to ensure a smooth start-up of powerful three-phase asynchronous motors, as well as to reduce the starting current when the motor is turned on. Reduction of starting current can be used to start the motor circuit breakers to a smaller operating current circuit, which increases the reliability of motor protection in case of overload or power failure.
 
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: potentiometer "Tr" to set the delay time within the selected range, the switch "multiplier" to set the time range and to select the delay time "tp" switching from "STAR" to "TRIANGLE", the green LED of the voltage supply "U", the yellow LED status of contactors "TRIANGLE" and the red LED status of starters "STAR".
 
OPERATION OF THE RELAY
 Relay controls power of starters motor windings that providing connection on a circuit "STAR" or "TRIANGLE" in the process of acceleration and the operating mode of the motor, respectively.
 For motor control is used two starters and relay. Starter to work on "STAR" circuit is connected to terminals 15 (16-18), starter to work on a "TRIANGLE" - to the contacts 25 (26-28). When the supply voltage relay switches on (lights «U» indicator), contacts 15-18 are closes, begins the counting of ramp time (Tr). On completion of ramp time contacts 15-18 of relay opens, after time of pause (tpause) contacts 25-28 of relay closes.
 The relay has 5 ranges delay time. Time range is selected by switch "multiplier". Ramp time (Tr) is determined by multiplying the number that preset by potenciometer "Tr" on multiplier of the selected range. At the same time set a fixed switching time (tswitch) 40ms or 80ms depending of installation area switch "multiplier". Relay produced in several versions with different supply voltage. Supply voltage AC is applied to the terminals "A1" and
 Напряжение питания АС подаётся на клеммы «А1» и «А2». Для исполнения на напряжение питания DC «+Uпит» подаётся на клемму «А1», а «-Uпит» на клемму «А2».
 
 WARNING: Switching ranges and setting delay time possible only after removing the voltage.
