Access Level Required: OPERATOR
This key is used to initiate the ramp up to rated speed
only if MSSP4-Turbine Start Mode is set for Manual
on the Configuration Screen 1. It appears only after the
turbine slow roll warm-up has been completed and the
turbine exhaust pressure is less than the programmed
value. Pressing this key causes the Chilled Liquid
Pump Start contacts (terminals 44-45 on the relay out-
put board) to close to start the chilled liquid pump Af-
ter the TDSP5-Chilled Liquid Flow Switch Check De-
lay shown on the Time Setpoints Screen, if the chilled
liquid flow switch is closed, the speed setpoint rapidly
increases to the SSP3-Fixed Speed setpoint shown on
the Speed Setpoints Screen at the RRSP4-Minimum
Rated Speed Ramp Rate shown on the Ramp Rate
Setpoints Screen. This causes the output signal to the
governor valve transducer to increase to open the gov-
ernor valve. After the key has been pressed, this object
disappears.
