FIGURE 39 - CONFIGURATION SCREEN 3
OVERVIEW
This screen is used to configure one spare analog out-
put and three spare digital outputs to duplicate specific
existing I/O points. These spares may be used for re-
mote signaling or to replace an existing point in the
event of a hardware failure.
PROGRAMMABLE
CAO – Configurable Analog Output
Screen: N/A
Range: Governor Position/Hotwell Level/HGV Position/Turbine
Speed/Steam Inlet Position
Default: Governor Position
This setpoint determines which existing analog output
control logic drives the 4-20 mA output signal from the
Frick Analog I/O Board analog output Channel #2. For
example, with the default setpoint, this output will be
4 mA at 0% and 20 mA at 100% control signal to the
turbine governor valve analog output.
CDOA – Configurable Digital Output
Screen: N/A
Range: Compressor Oil Pump/Turbine Oil Pump/Hotwell Pump/
Vacuum Pump/Turbine Start Relay
Default: Compressor Oil Pump
This setpoint determines what existing digital output
control logic drives the 120 VAC digital output on the
Frick Digital I/O Board digital output Channel #22.
For example, with the default setpoint, this output is on
when the compressor VS oil pump drive is enabled to
start the compressor oil pump. If the setpoint is Hotwell
or Vacuum Pump, this output is on if either the lead or
stand-by pump run output is on.
CDOB – Configurable Digital Output
Screen: N/A
Range: Compressor Oil Pump/Turbine Oil Pump/Hotwell Pump/
Vacuum Pump/Turbine Start Relay
Default: Compressor Oil Pump
This setpoint determines what existing digital output
control logic drives the 120 VAC digital output on the
Frick Digital I/O Board digital output Channel #23. For
example, if set for Turbine Oil Pump, this output is on
when the turbine auxiliary oil pump run output is on.
CDOC – Configurable Digital Output
Screen: N/A
Range: Compressor Oil Pump/Turbine Oil Pump/Hotwell Pump/
Vacuum Pump/Turbine Start Relay
Default: Compressor Oil Pump
