The PSL for this TCS scheme 2 is practically the same as that of TCS scheme 1. The main difference is that
both opto-inputs must be low before a trip circuit fail alarm is given.

TRIP CIRCUIT SUPERVISION SCHEME 3
TCS Scheme 3 is designed to provide supervision of the trip coil with the breaker open or closed, but unlike
TCS schemes 1 and 2, it also provides pre-closing supervision of the trip path. Since only one opto-input is
used, this scheme is not compatible with latched trip contacts. If you require CB status monitoring, further
opto-inputs must be used.

Figure 45: TCS Scheme 3
When the CB is closed, supervision current passes through the opto-input, resistor R2 and the trip coil.
When the CB is open, current flows through the opto-input, resistors R1 and R2 (in parallel), resistor R3 and
the trip coil. Unlike schemes 1 and 2, supervision current is maintained through the trip path with the breaker
in either state, therefore providing pre-closing supervision.
