Relay K2 (Alarm 2/Trip) is connected in operating current mode. It makes no trip signal when supply voltage is switched on. A delayed switching time relay in series is not required. Thus, the MSF220K can also be used when the supply voltage for the device is provided by the monitored transformer. -
Page 3: Overview Of Functions
5 Connecting diagram 6 Detailed description PTC sensors with different nominal response temperatures (NRT) can be connected to MSF220K. When everything is ok, relay K1 (Alarm 1) is picked up (11-14 closed) and relay K2 (Alarm 2, trip) is released (21-24 open). -
