48V comes into P1 which goes though the opto anode then back to p2 (-48v gnd) from the cathode.
This will drive the START_TTL_IN low

Q2 should start conducting which would allow for Q1 to switch 48V into IP+ pin. This will come out IP- pin on the current monitor (u3). If Q2 does not conduct it should make Q1 open as well and no current should be conducting through Q1.
