Figure 4-1. Basic Operational Architecture
Table 4-1. Automatic Start-Up Procedure
1. Initial – all discrete
inputs are off.
Shutdown input is in
the shutdown state. Initial Settings:
Speed reference is set to 0%.
Valve limiter is 0%.
Actuator Output (Terminal 13-14) will be at 0 mA.
Shutdown Relay (Terminal 44) will be Shutdown condition.
The turbine should be stopped, the speed signals (Terminal 25-26 and/or 28-29)
is minimum.
Analog Input 1 and 2, Load sharing line and PTs, CTs are normal range based
on their configurations.
2. Shutdown / Run
discrete input. Discrete Input- A (Terminal 34) should be set to the RUN (Closed) position to
start and run the turbine, and Shutdown (Open) to shutdown the actuator output.
Set the Modbus Controlled Shutdown from the Modbus controller to True to run
the turbine, and to False to shutdown the, if used.
3. Reset all alarms and
shutdown latches. Discrete Input- B (Terminal 35) should be toggled to reset all alarms and
shutdown latches. This will affect the initial speed setpoint only after all trip
conditions are cleared. The actuator or valve does not open by the reset input.
