SECTION 2 - OPTIVIEW CONTROL CENTER INTRODUCTION
Shaft horizontal vibration
Displays the movement of the turbine shaft on the shaft
end of the turbine. It is measured by a proximity probe
installed at approximately 45 degrees from the verti-
cal center on the right side when facing the governor
end of the turbine. The probe signal is converted to a
4-20 mA signal by a transmitter in the Turbine Box and
connected to the Analog I/O Board in the Control Cen-
ter. This text and data field only appears if MSSP13-
Turbine Shaft Vibration Sensors is set for Enabled or
the MSSP4-Turbine Start Mode is set for Auto on Con-
figuration Screen 1.
Shaft vertical vibration
Displays the movement of the turbine shaft on the shaft
end of the turbine. It is measured by a proximity probe
installed at approximately 45 degrees from the verti-
cal center on the left side when facing the governor
end of the turbine. The probe signal is converted to a
4-20 mA signal by a transmitter in the Turbine Box and
connected to the Analog I/O Board in the Control Cen-
ter. This text and data field only appears if MSSP13-
Turbine Shaft Vibration Sensors is set for Enabled or
the MSSP4-Turbine Start Mode is set for Auto on Con-
figuration Screen 1.
governor horizontal vibration
Displays the movement of the turbine shaft on the gov-
ernor end of the turbine. It is measured by a proxim-
ity probe installed at approximately 45 degrees from
the vertical center on the right side when facing the
governor end of the turbine. The probe signal is con-
verted to a 4-20 mA signal by a transmitter in the Tur-
bine Box and connected to the Analog I/O Board in the
Control Center. This text and data field only appears
if MSSP13-Turbine Shaft Vibration Sensors is set for
Enabled or the MSSP4-Turbine Start Mode is set for
Auto on Configuration Screen 1.
governor vertical vibration
Displays the movement of the turbine shaft on the gov-
ernor end of the turbine. It is measured by a proximity
probe installed at approximately 45 degrees from the
vertical center on the left side when facing the gover-
nor end of the turbine. The probe signal is converted to
a 4-20 mA signal by a transmitter in the Turbine Box
and connected to the Analog I/O Board in the Control
Center. This text and data field only appears if MS-
SP13-Turbine Shaft Vibration Sensors is set for En-
abled or the MSSP4-Turbine Start Mode is set for Auto
on Configuration Screen 1.

oil Temperature
Displays the temperature of the supply oil leaving
the oil cooler down stream of the temperature control
valve. This text and data field only appears if the
MSSP6-Turbine Lubrication Type is set for Pump on
Configuration Screen 1.
oil pressure
Displays the pressure of the supply oil leaving the
oil cooler down stream of the temperature control
valve. This text and data field only appears if the
MSSP6-Turbine Lubrication Type is set for Pump on
Configuration Screen 1.
oil Cooling valve (led)
Illuminates when the digital output controlling the
solenoid valve or electric actuator in the turbine oil
cooler liquid inlet line is energized to allow cooling
liquid into the cooler. If the MSSP6-Turbine Lubrication
Type is set for Ring on Configuration Screen 1, this
is the valve controlling the cooling liquid inlet to the
bearing oil reservoirs on the turbine.
aux oil pump run output (led)
Illuminates when the turbine auxiliary oil pump
contactor is energized to start the oil pump. This object
only appears if the MSSP6-Turbine Lubrication Type
is set for Pump on Configuration Screen 1.
aux Contact (open/Closed)
Displays the status of the auxiliary contact on the
turbine auxiliary oil pump contactor. The status will
change from Open to Closed after the Run Output LED
illuminates indicating that the contactor has pulled
in. This object only appears if the MSSP6-Turbine
Lubrication Type is set for Pump on Configuration
Screen 1.
vacuum Solenoid (led)
Illuminates when the vacuum breaker solenoid valve
is energized (normally open) to isolate the turbine
exhaust from atmospheric pressure.
Trip Solenoid (led)
Illuminates when the Turbine Trip Valve air dump
solenoid valve is energized to open the turbine trip
valve.
