The Sequence can be restarted again by pressing the front panel YES key from the Sequence Status screen (screen 2), closing the Halt/Continue contact, or selecting Continue from a Modbus communications link. Table 5-3 lists the Auto Start status messages that may appear on the display and the meanings of each. MESSAGE 2 MEANING Disabled Auto Start Sequence is disabled Halted Sequence has been halted Mvg Low Idle Speed Setpt is moving to low idle At Low Idle Speed Setpt is holding at the low idle Setpt Mvg Hi Idle Speed Setpt is moving to high idle In Crit Band Setpt is moving through the critical avoidance band At High Idle Speed Setpt is holding at the high idle Setpt Mvg to Rated Speed Setpt is moving to rated Setpt Completed Auto Start Sequence is completed Table 5-3. Auto Start Messages The following Auto Start Sequence indications are available through the Modbus links: Setpt Moving to Min, Setpt at Low Idle, Ramping to High Idle, Setpt at High Idle, Turbine in Critical Speed Band, Ramping to Rated, and At Rated. In addition to these indications, the Low Idle Speed Setpoint, Low Idle Delay Time, Time Remaining at Low Idle, Low Idle to High Idle Rate, High Idle Speed Setpoint, High Idle Delay Time, Time Remaining at High Idle, High Idle to Rated Rate, Rated Speed Setpoint, Run Time (hours), and Hours Since Trip analog values are also available providing comprehensive sequence information. Direct Setpoint Entry The Speed setpoint can be directly set to a specific value, that is not within a critical speed avoidance band, using the ENTER key from the Speed Setpt screen (screen 4). 

The messages that appear on the display are shown in Figure 5-5. There are limits on the range of the Speed setpoint that can be entered. The Speed setpoint must be below the maximum governor setting and above the idle setting. Once above minimum governor speed, the setpoint cannot be set below minimum governor. Also, if the unit is driving a generator and the unit is on-line, the speed setpoint cannot be set below the 3% minimum load setting (tunable in the Service Mode). The Speed setpoint can also be directly entered from either of the Modbus links, however, the allowed range is between the minimum and maximum governor speed settings. The allowed setpoint range is limited between the minimum load and the maximum governor settings if the unit is driving a generator and the unit is on-line. Both the speed setpoint and the Modbus Entered Speed setpoint are available over the communication link to provide feedback for directly entered Modbus values.
