Since RSS is a secondary speed setting function, the Speed PID must be incontrol of the 505E’s LSS bus to allow the RSS to position the actuator. When configured as a generator application, the RSS will not take control unless both breakers are closed and the speed PID is in control. When not configured as a generator application, turbine speed must reach min governor before the RSS can take control. The Cascade and Auxiliary (if configured to be enabled/disabled) controls are automatically disabled if RSS is enabled. The Remote Speed Setpoint may be enabled or disabled from the 505E keypad, external contact or Modbus. The last command given from any of these three sources dictates the enabled/disabled state. It does not matter whether the last command was given from the keypad or other devices. A contact input can be programmed to perform as an external “Remote Speed Setpoint Enable” function. When this programmed contact is open the RSS is disabled, and when it is closed the RSS is enabled. The contact can be either open or closed when a trip condition is cleared. If the contact is open it must be closed to enable the RSS. If the contact is closed it must be opened and reclosed to enable the RSS. If the milliamp signal to the Remote Speed setpoint input is out of range (below 2 mA or above 22 mA) an alarm will occur and the Remote Speed setpoint will be inhibited until the input signal is corrected and the alarm is cleared. Remote Speed Setpoint Status Messages The Remote Speed Setpoint may be in one of the following states (505E front panel screen messages): • Disabled—The remote setpoint function is not enabled and will have no effect on the speed setpoint. • Enabled—The remote setpoint has been enabled. • Active—The remote setpoint is in control of the Speed setpoint but the speed PID is not in control of the actuator output. • In Control—The remote setpoint is in control of the Speed setpoint and the speed PID is in control of the actuator output. • Inhibited—RSS cannot be enabled.
The input signal has failed, a controlled stop is selected, the unit is shut down, or RSS is not programmed. When enabled, the Remote Speed setpoint may not match the speed setpoint. In this case, the speed setpoint will ramp to the Remote Speed setpoint at the programmed ‘Speed Setpoint Slow Rate’ setting (as defaulted in the Service mode). Once in control, the maximum rate that the speed setpoint will ramp, for a RSS change, is at the programmed ‘Remote Speed Setpoint Max Rate’ setting. If the ‘Remote Speed Setpoint Max Rate’ were set at 10 rpm/sec and the Remote Speed setpoint analog input instantly moved from 3600 rpm to 3700 rpm, the Speed setpoint will move to 3700 rpm at 10 rpm/sec. Refer to Volume 2 of this manual for information on related Service mode tunables. All pertinent remote speed setpoint parameters are available through the Modbus links, refer to Chapter 6 for a complete listing of Modbus parameters.
