If the unit was tripped for 12 hours, the 505E would interpolate between the Hot and Cold parameters and use the following rates and delays (viewed in the Service Mode): LOW IDLE DELAY = 20 MIN RATE TO HI IDLE = 10 RPM/SEC HI IDLE DELAY = 10 MIN RATE TO RATED = 15 RPM/SEC HOURS SINCE TRIP (HRS) = 12 hrs Based on the example’s configuration and trip time, the speed setpoint would ramp to 1000 rpm at the ‘Rate to Min’ setting and hold for 20 minutes, move to 2000 rpm at 10 rpm/sec and hold there for 10 minutes, and lastly, move to 3400 rpm at 15 rpm/sec. At 3400 rpm, the sequence would be completed. If the unit was tripped for 2 hours or less and restarted, the 505E would use the Hot Start parameters. If the unit was tripped for 22 hours or longer and restarted, the 505E would use the Cold Start parameters. The ‘Hours since Trip’ timer starts counting when the unit shuts down and the speed has coasted down below the low idle speed setting. NOTE The 505E will automatically set the hours-since-trip timer to its maximum setting of 200 hours to ensure a cold start is selected after a power up or upon exiting the Program mode. The hours-since-trip timer will reset only when the turbine speed has increased above the minimum governor speed setting. The Auto Start Sequence can be halted at any time from the 505E keypad, contact input or through Modbus communications. The sequence can be halted by a halt command, a raise or lower speed setpoint command, or when a speed setpoint is directly ‘Entered’ from the 505E keypad or through Modbus communications. When the sequence is halted, the delay timers do not stop if they have already started counting down. The sequence will resume when a Continue command is issued. If there were 15 minutes remaining to hold at an idle speed and the Halt command was issued for 10 minutes before a issuing a Continue command, the sequence would remain at the idle speed for the remainder of the ‘Hold Time’—which in this example is 5 minutes. The halting and continuing of the Auto Start Sequence can be performed through the 505E keypad, contact input, or Modbus. The last command given from any of these three sources determines the mode of operation. However, a shutdown condition will disable this function requiring it to be re-enabled after a start-up has been performed.

If a 505E contact input is programmed to function as a Halt/Continue command, the sequence is halted when the contact is open, and continued when the contact is closed. The Halt/Continue contact can be either open or closed when a Reset command is given. If the contact is closed, it must be opened to allow the sequence to be halted. If the contact is open, it must be closed and reopened to halt. Alternatively, a relay can be programmed to indicate when the Auto Start Sequence is halted.
