Contact Inputs.
This area of the Logic Triggers tab lists the available DECS-200 contact inputs that can
be selected to trigger a data log report. The following contact inputs are available for triggering a data log
report:
• 52J/K
• 52L/M
• Alarm Reset
• AVR
• FCR
• Pre-Position
• Secondary Enable
• Start
• Stop
Any combination of contact inputs may be selected.
Relay Outputs.
This area of the Logic Triggers tab lists the DECS-200 contact outputs that can be
selected to trigger a data log report. The following relay outputs are available for triggering a data log
report:
• Relay 1
• Relay 2
• Relay 3
• Stop/Start
• Watchdog
Any combination of relay outputs may be selected.
Alarm States.
This area of the Logic Triggers tab lists the available alarm conditions that can be selected
to trigger a data log report. The following alarm conditions are available for triggering a data log report:
• Exciter field overcurrent
• Exciter field overvoltage
• Exciter open diode
• FCR mode
• Generator overvoltage
• Generator sensing <10 Hz
• Generator undervoltage
• Loss of field
• Loss of sensing
• Overexcitation limit
• Setpoint at lower limit
• Setpoint at upper limit
• Shorted exciter diode
• Stator current limit
• Underexcitation limit
• Underfrequency
Any combination of alarm states may be selected.
System Status, Start/Stop.
Enables the Start or Stop mode to trigger a data log report. Selecting “No
Trigger” disables a Start or Stop mode trigger.
System Status, Soft Start.
Enables a data log report to be triggered when Underfrequency protection is
active or inactive. Selecting “No Trigger” disables a Soft Start trigger.
System Status, Underfrequency.
Enables a data log report to be triggered when either AVR mode or FCR
mode is active. Selecting “No Trigger” disables an Underfrequency trigger.
System Status, Control Mode.
Enables a data log report to be triggered when either AVR mode or FCR
mode is active. Selecting “No Trigger” disables a control mode trigger.
