The valve limiter must then be raised by the operator until governor takes control. （One of the three start modes must be selected before the unit will run）RATE TO MIN= RPM/SEC df

5、lt=10.0（0.1,500）Rate at which speed setpoint moves to lowest controlling speed on start. The min controlling speed will be either idle, if idle/rated is used, or low idle, if the auto start sequence is used. If neither of this startup features is used, the min speed will be the minimum governor spee

6、d setpoint.HP VALVE LIMITER RATE= 1 %/SEC dflt=5.0（0.1,25）Rate at which the valve limiter moves. When using a semiautomatic or automatic start, this setting should be very slow-typically less than 2%/sec. When using a manual start, this setting is less critical and can be left at the default of 5%/s
