Time relay PCG-417 PCG-417DUO

Intended use
To control the STAR-TRÓJKAT contactor switching system. Operation
The controller has a special system of two electromagnetic relays, which eliminates the risk of switching on two contactors at the same time. Each of the relayóin  controls the corresponding contactor. At the moment of switching from the STAR to TRÓJANGLE system, the first relay opens the “star” contactor, there is a forced time interval, and then the second relay turns on the “trójangle” contactor. After turning on the power, contact  STARS will be switched to position 7-9 for the set start time t1. The TRÓJANGLE contact remains in position 10-11. After the starting time t1, the STAR contact will be  switched to position 7-8 (the TRÓJANGLE contact remains in position 10-11) and there will be a break in switching at the set time t2. After the time t2 has elapsed, the TRÓJANGLE contact will be switched to position 10-12 and remains in this state until disconnection  supply voltage (STAR contact remains in position 7-8).
