Relay outputs
Twenty relays outputs are available. All relay outputs can be used as normally open or normally closed
(configurable). They’re all configurable and the available configuration is shown below:
•
Nozzle Position #1 to Nozzle Position #4: These are four outputs to nozzle position switch. Each
nozzle position switch is individually configured.
•
Speed Switch #1 to Speed Switch #6: These are six outputs to speed switch. Each speed switch is
individually configured.
•
General Shutdown: An output that monitors if the control is in shutdown mode. The output also
depends on its configuration. If “Reset clears trip” is enabled the output will be energized when the
trip occurs and when the reset command is sent the output will be de-energized. If “Reset clears trip”
is not enabled the output will be energized while the control is in shutdown mode, even if the reset
command is sent. If “External trips in trip relay” is not selected, this output will not be energized if a
external trip occurs.
•
General Governor Alarm: An output that monitors if the control has any alarm.
•
Creep indication: Output to indicate that the turbine is creeping.
•
Speed Bias Enabled: Output to indicate the Speed Bias is enabled.
•
Start Perm Enabled: Output to indicate that the start permissive is in condition to start the turbine.
•
Overspeed Shutdown: Output to indicate that an overspeed shutdown exists.
•
Gen Breaker open Command: Output used to open the generator breaker.
•
Active Power Switch #1 to Active Power Switch #4: These are four outputs to active power switch.
Each active power switch is individually configured.
•
Ready for Start: Indicates that the turbine is ready to start (no shutdown and start permissive ok).
•
Turbine Stable Speed: Indicates that the turbine is running and the speed is stable (speed between
configurable values during a configurable time).
•
Reset Command: When the control receives a command to reset (Modbus, discrete input or Display)
this output will pulse to reset optional external equipment.
•
Close Deflector: Used to send the command to close the deflector during the normal operation. The
command can be configured as continuous or pulse. If configured to continuous the output will remain
activated during all time that the deflector needs to be closed. If configured to pulse the output will
pulse to close the deflector during a configured time.
•
Open Deflector: Used to send the command to open the deflector during the normal operation. The
command can be configured as continuous or pulse. If configured to continuous the output will remain
activated during all time that the deflector needs to be opened. If configured to pulse the output will
pulse to open the deflector during a configured time.
•
All Nozzle Position Fail: This output will be activated if all nozzles in use has its analog input signal
failed.
•
Level Signal Fail: This output will be activated if level signal input fails.
•
Remote Speed Sig Fail: This output will be activated if level signal input fails.
•
Speed Bias Input Signal Fail: This output will be activated if Speed Bias signal input fails.
•
Incomplete Start: If the operator send a command to start and the turbine does not reach a
configured speed in a configured time the Incomplete Start shut down will be issued and this output
will be activated.
•
All Nozzle Position Major Mismatch: If all used Nozzles have Major mismatch shutdown this output
will be activated.
•
Total Speed Signal Fail: If all speed probes in use fail this output will be activated
•
Speed Signal Fail #1: If the speed input 1 fails this output will be activated.
•
Speed Signal Fail #2: If the speed input 2 fails this output will be activated.
•
Analog Nozzle Lim Sig Fail: This output will be activated if analog nozzle limit signal input fails.
•
Remote Baseload Signal Fail: This output will be activated if remote baseload signal input fails.
•
Power Transducer Sig Fail: This output will be activated if power transducer signal input fails.
•
Internal Fault: This output will be activated if there is any hardware fault in the control.
•
Control Powered On: This output is always on and can be used as a watch dog fault.
