Flow Monitor
If steam flow is configured in the UDC controller, current steam
flow rate is displayed in text value and in a bar graph on the
page. Upper and lower limits of the steam flow range are
displayed on the page next to the bar graph.
Fig. 110. Steam/Fuel Oil Flow Monitor.
If gas or fuel oil flow is configured in the UDC controller, current
gas/fuel oil flow rate is displayed text value and in a bar graph
on the page. The upper and lower limits of the Gas/fuel oil flow
range are displayed on the page next to the bar graph.
If totalization is configured in the UDC controller, the user can
select which flow (steam or gas/fuel oil) to accumulate total
units flowed. The user can start, stop, and reset the totalization
count in the UDC controller. The total flow is displayed on the
page. If the UDC controller has been totalizing prior to
displaying this page, the current totalized value displays on the
screen and continues to totalize automatically. Totalization
doesn’t start nor stop automatically when leaving this page.
Thermal Shock Controller
Current water supply temperature is displayed in text value and
in a temperature bar graph on the page. Upper and lower limits
of the water supply temperature range are displayed next to the
temperature bar graph.
Fig. 111. Thermal Shock Controller.
The control setpoint for optimal water temperature is displayed
on the page. This setpoint is used for PID modulation of mixing
valve/pump and for shock alarm.
The user can adjust the control setpoint on the page. The
status of the shock alarm (when water supply temperature falls
below alarm setpoint) is indicated by an LED that is green
when temperature is below the setpoint and red when
temperature is above the setpoint
Both setpoints can be adjusted by the Up Arrow and Down
Arrow buttons after successfully logging in with the S7999D
System password.
Control of the mixing valve/pump can be manually adjusted by
selecting the yellow “Auto Output” button. The Up Arrow and
Down Arrow buttons are used to adjust the modulation outputs
(override) in 1% (0.16 mA) increments.
Offline Profile Curve Builder
The Offline Profile Curve Builder is used to create a curve
without having the burner firing (not in Commissioning mode).
The S7999D is capable of storing multiple profile curves in its
flash memory. The curves can be stored by saving them during
commissioning time, building them from scratch, loaded from a
USB stick memory, copied to a USB stick memory, or editing
an existing one with this Offline Curve Builder. Each curve may
contain up to 24 points, but can be as small as only one point
of any type for some user-defined purpose (partial curve).
Entire curves can be copied, renamed or deleted. The Curve
Builder checks the curve for some validity when it is saved, but
it reserves all safety validation to the R7999 at commissioning
time. Basic validity checking will display which points have
errors and the type of error involved. It does not apply all the
same safety checks and rules that the R7999 does, so some
points may not get loaded during commissioning. The R7999
may reject any invalid points or slopes that do not fit within
actual actuator spans.
When the user selects the “PROFILE CURVES” button, a page
similar to Fig. 112 displays.
Fig. 112. Offline Profile Curve Builder.
A list of all current profile curves stored in the S7999D flash
display on the left side of the screen. Information about the
currently selected curve displays on the right side of the
screen. Selecting a different curve in the list on the left causes
the right side to get updated with information about that curve.
A row of buttons is displayed on the bottom of the screen that
provides the user with different curve functions:
• “Add”—to add or create a new profile curve.
• “Edit”—to edit the settings in the currently selected curve.
