Electrode Boiler
7.12b - Factory Settings
The Factory Settings configuration screen allows
the setting of crutial setpoints during the initial
startup of the boiler. These setpoints are typically
determined at startup and are not changed in the
normal course of boiler operation. These
parameters are set by Cleaver Brooks and should
only be changed by qualified and authorized
personnel. The user must be logged on to modify
these factory setpoints. This screen is accessed
from the Operating Setpoints configuration
screen. Software Switch SetPoints (Soft Switch
SPs) can be accessed from the Factory Settings
screen.
The following is a descriptive list of the factory
setpoint variables:
• Steam Press. (psi)
Defines the scaled range for the steam pressure values of the system.
• Header Press. (psi)
Defines the scaled range for the header pressure values of the system.
• Water Level (%)
Defines the scaled range for the water level of the system.
• Shield Position (%)
Defines the scaled range for the shield position transmitter from "Full-Down" to "Full-Up" position of
the shield.
• Cond. Xmit. (s)
Defines the conductivity range for the conductivity transmitter.
• Power Analog Input (MW)
Defines the scaled range of the analog power input in megawatts (MW).
• VSD #1/#2/#3 Speed (%)
Defines the scaled speed of each of the pump VSDs.
• Shield Ramp Increment Size (%)
Defines the percentage-based increment at which the shield travels during start-up mode when the
boiler pressure is below the "Press for Release to Mod (psi)" setpoint located on the Operating Setpoints
screen.
• Shield Ramp Inc. Delay (sec)
Defines the time delay before moving to the next shield increment during start-up mode when the
boiler pressure is below the "Press for Release to Mod (psi)" setpoint located on the Operating Setpoints
screen.
