Combined operate and start alarm signal

The operate outputs of all the protection functions (except for underpower protection),
and the external trip from AVR and turbine are combined in the OR-gate to get a
common Operate output. In addition, the activation of binary input COM101.BI12,
that is, the low pressure lockout will also trip the generator circuit breaker. This
common operate signal is connected to a tripping logic. It is also available as an alarm
binary output, PSM SO1, with a settable minimum alarm delay of 80 ms.
Similarly, a common Start output is derived from the start outputs of all the protection
functions (except for underpower protection) combined in an OR-gate. The output is
available as an alarm binary output PSM SO2 with a settable minimum alarm delay of
80 ms.
These combined operate and start signals are also connected to trigger the disturbance
recorder.
