The trip circuit supervision hardware includes constant current generator to provide
trip circuit supervision (TCS) current and TCS input that can be connected to the TCS
function with Application Configuration in PCM600. See trip circuit supervision
function TCSSCBR in the protection relay's technical manual for TCS connections.
When testing TCS connections, the TCS button needs to be pushed. The operation of
TCS can be seen on the HMI. When testing TCS, its output (PODP1, PODP2, PODP3,
SP06 or SP08) needs to be in inactive mode.
