Shutdown override
If the Binary input shutdown override (Sd override) is closed, all 2
nd
level protections are disabled to allow
engine run in an emergency situation, e.g. sprinkler devices power supply.
All protections are shown in Alarmlist and recorded into History, but the controller doesn’t stop the engine
because of them. If the input is deactivated and some protections are still active or not yet reset, the
controller starts to take these protections into account and consequently stops the engine.
Hint:
All 2
nd
level protections are locked out, except of these:
- Emergency stop
- Overspeed
- Underspeed (only if
Fuel solenoid
= GAS ENGINE)
- Binary and analog protections configured as
Sd override
type. In fact this protection type means
"Unoverridable shutdown", i.e. it works the same way as standard shutdown protection, however it can not
be overriden (blocked) by the
Sd override
input.
