The Speed setpoint will again ramp to the Rated Speed setting if the Rated command is re- issued. To re-issue the Rated command press the front panel YES key from the Idle/Rtd screen (screen 1), toggle the Idle/Rated contact open and closed again (if programmed) or select Go To Rated from a Modbus communications link. The Speed setpoint will ramp to the Idle Speed setting upon startup. However, the Idle Speed setting can be re-selected, when conditions allow, (see Chapter 3) by pressing the front panel NO key from the Idle/Rtd screen (screen 1), opening the Idle/Rated contact (if programmed), or selecting Go To Idle from a Modbus communications link. Another feature of Idle/Rated function is the ‘Ramp to Rated’ option which allows the Speed setpoint to only move to the Rated Speed setting; Idle is not selectable. This feature is configurable in the Service Mode only. When this feature is used with the Idle/Rated contact input, closing the contact results in the Speed setpoint ramping to the Rated Speed setting and opening the contact stops the speed setpoint ramp—rather than selecting Idle. To continue ramping to the Rated Speed setting, re-close the contact, press the front panel YES key from the Idle/Rtd screen (screen 1) or select Go To Rated from a Modbus communications link. Table 5-2 lists the Idle/Rated status messages that may appear on the front panel display and the meanings of each. MESSAGE 1 MEANING Stopped Idle/Rated ramp has been stopped Mvg to Idle Speed Setpt is moving to idle At Idle Spd Speed Setpt is at the idle Setpt In Crit Band Setpt is moving thru the critical avoidance band Mvg to Rated Speed Setpt is moving to the rated Setpt At Rated Spd Speed Setpt is at the rated Setpt Rtd Inhibited Selection of rated is not allowed Idle Inhibited Selection of idle is not allowed Table 5-2. Idle/Rated Messages The following indications are available through the Modbus links: Ramping to Idle, At Idle, Turbine in Critical Speed Band, Ramping to Rated, and At Rated. In addition to these indications, the Idle Speed Setpoint and Rated Speed Setpoint analog values are also available. Auto Start Sequence When a RUN command is issued, the 505E automatically displays the SPEED screen (unless used with the Semiautomatic start mode) and shows the Status of the Auto Start Sequence (screen 2). The Speed setpoint is instantly set to the turbine’s actual speed and the sequence will continue from this point. This sequence is automatic, however the sequence can be halted. Halting the Auto Start Sequence can be performed by pressing the front panel NO key from the Sequence Status screen (screen 2), opening the Halt/ Continue contact (if programmed), selecting Halt from a Modbus communications link, or selecting Speed Setpt Raise or Lower. To provide feedback, a relay can be programmed to indicate the Auto Start Sequence is Halted.
