12 OVERSPEED SETTING dflt = 2000.00 (0.00, 4000)
The maximum speed limit. The 2301D initiates a shutdown when the engine
speed reaches this level.
13 RST TO RATED AT CB CLOSE dflt = TRUE (TRUE, FALSE)
This resets the speed bias after the circuit breaker is closed and the speed
setting returns to rated.
14 RST TO RATED INSTANT dflt = TRUE (TRUE, FALSE)
Used to return the engine immediately back to rated.
15 GRID FREQ IS 50 HZ dflt = FALSE (TRUE, FALSE)
If set FALSE 60 Hz is selected.
16 RSE/LWR STOP IDL/RTD RMP dflt = TRUE (TRUE, FALSE)
If set TRUE the raise and lower inputs are active during ramping from idle to
rated. When FALSE the raise and lower inputs are disabled until rated speed is
reached.
17 ENABLE AUTO IDLE/RATED dflt = FALSE (TRUE, FALSE)
An automatic idle to rated switch which activates rated after idle is reached and a
certain time has expired. Tunable in service mode.

On a forward-acting actuator, the fuel demand will go to 0%. On a
reverse-acting actuator, the fuel demand will go to 100%, and will
cause the mechanical governor to take over.

8 Use Modbus (for 2301D-EC with Modbus)
02 DISPLAY DI B FUNCTION (monitor)
Shows the function of input B.
