Description

Purpose
The electric motor at start-up consumes a current many times higher than the rated one. Therefore, starting a high-power electric motor with a weak supply network is accompanied by a voltage drop in the phases, which leads to malfunctions in other equipment. The PCG-417 programmable time relay controls contactors that switch the motor windings from the "STAR" circuit at start-up to the "DELTA" circuit in operating mode and significantly reduces the starting current.
Principle of operation:
The time relay programmable PCG-417 has two relay outputs. Each controls a separate contactor. At the moment of start-up, its first output turns on the contactor Sstar (contacts 7-9 close) and the motor windings are connected according to the "STAR" scheme. Therefore, the voltage on them is 1.73 times less than the nominal, which reduces the starting current. After the time t1 for the motor to enter the operating mode, the contactor Sstar turns off (contacts 7-9 open), a pause of duration t2 occurs, then the contactor Streug turns on (contacts 10-12 close), turning on the windings according to the "TRIANGLE" scheme.
