S7999 CONTROLINKS™ DISPLAY MODULE
DISPLAY MODULE OPERATION
LFOn—the system is firing and the firing rate would
normally be provided by either the CmA input (Auto) or the
Manual Potentiometer input (Manu); however the LF input
is on so the normal rate request is overridden, and the
system is firing at the Lightoff rate.
This section describes the layout and operation of the
ControLinks™ Display Module. See Fig. 5.
Rate
The RATE item shown in Fig. 5 is the current firing rate
request that is driving the R7999. Possible values are shown
below using dashes to represent the positions where digits
would appear:
ControLinks™
MODE
RATE
STATUS
C--%—shows the CmA input current requested rate as a
percentage of its full scale: 4 mA (0%) to 20 mA (100%)
range, effective during Auto mode.
LINE 2
Air -- Fuel -- FGR --
M--%—shows the Manual potentiometer currently
requested rate (0% to 100%), effective during Manu
operation.
SCROLL
X--%—shows the XmA input current value as a percentage
of full scale range: 4 mA (0%) to 20 mA (100%), effective
during a Low Fire Hold when this value is (or has been)
less than the Enforce threshold and has not yet crossed
the Release threshold.
M20037
Fig. 5. Identification of S7999 ControLinks™
Display Module display items.
Mode
The MODE item shown in Fig. 5 is the current operating mode
of the R7999. The two primary modes are Auto and Manu,
which correspond to the R7999 Auto/Manual input switch.
Additionally, when the system is firing, other modes may be
shown as described below. Possible MODE values are:
Auto—the R7999 is in automatic operating mode, in which
the firing rate is (or will be, when the system is firing)
provided by the CmA input. Auto will be shown even when
the system is not firing or is getting ready to fire, when the
R7999 Auto/Manual switch is in the Auto position.
Manu—the R7999 is in manual operating mode in which
the firing rate is (or will be, when the system is firing)
provided by the manual potentiometer. Manu will be shown
even when the system is not firing or is getting ready to
fire, when the R7999 Auto/Manual switch is in the Manual
position.
Lim—the Maximum Firing Rate Limiting feature is enabled
(a commissioning option) and the R7999 manual
potentiometer setting is currently limiting the firing rate to a
value that is less than the CmA input currently requested
rate.
Hold—the Low Fire Hold feature is enabled (a
commissioning option) and a Low Fire Hold is currently
active and is limiting the firing rate, because the XmA input
is (or has been) below the Enforce threshold and has not
yet crossed the Release threshold.
HFOn—the system is firing and the firing rate would normally be provided by either the CmA input (Auto) or the
Manual Potentiometer input (Manu); however the HF input
is on so the normal rate request is overridden, and the
system is, instead, firing at the Purge rate.
5
P--%—shows the Purge rate (a commissioning setting),
effective during purging and also when the normal firing is
overridden because the HF input is on during modulation.
L--%—shows the lightoff rate (a commissioning setting),
effective during ignition and also when the normal firing is
overridden because the LF input is on during modulation.
Stop—shows that the system is currently idle and the
motors have been commanded to their stop positions (as
set during commissioning).
Status
The STATUS item shown in Fig. 5 shows the R7999 operating
state. The following are status displays and descriptions:
Startup—the R7999 is starting up.
Initialize—the R7999 is in the initialization stage of its
startup procedure.
Lockout—a fault has occurred, the Alarm output is
energized, and the LCO has been turned off. Manual
intervention is required; the R7999 must be manually reset
before normal operation will continue.
Alarm-Hold—a fault condition is currently present, the
Alarm output is energized, and the LCO has been turned
off. Normal operation will continue if and when the fault
condition clears (without requiring a manual reset) but the
R7999 will continue to hold as long as the fault condition
persists.
Standby—the R7999 is idle, waiting for a demand input at
the LCI terminal.
65-0262
S7999 CONTROLINKS™ DISPLAY MODULE
Proc-Demand—the R7999 has detected an input at the
LCI terminal and is processing a demand request from the
burner control by moving the actuators to the position
requested by the HF ( or LF) inputs.
Purge—the R7999 has completed moving the actuators to
the Purge position, in response to the LCI and HF inputs,
and has turned on the HFP (High Fire Proven) output.
LINE2
The LINE2 item shown in Fig. 5 normally describes the
contents of the second line of the display; however, when the
display is first powered up, this area is used to indicate the
progress of the initialization of the S7999 display itself.
Lightoff—the R7999 has completed moving the actuators
to the lightoff position, in response to the LCI and LF
inputs, and has turned on the LFP (Lightoff Position
Proven) output.
Modulate—the R7999 has detected that the LCI and MV
inputs are on, and the HF and LF inputs are off, and is
therefore controlling the firing rate, using either automatic
or manual mode.
Run-Lightoff—the R7999 would be in the Modulate
position, except that the LF input is also on. Therefore, the
R7999 is ignoring its normal rate inputs (CmA or the
Manual Potentiometer) and is, instead, firing at the lightoff
rate.
Run Purge—the R7999 would be in the Modulate
condition, except that the HF input is also on. Therefore,
it is ignoring the normal rate inputs (CmA or the Manual
Potentiometer) and, instead, is firing at the Purge rate.
Post-Purge—the R7999 recently left the Modulate
condition because LCI turned off and is moving (or has
finished moving) the actuators to the position commanded
by the HF and LF inputs. It assumes that the burner control
is post-purging the combustion chamber and continues to
display “Post-Purge” for the time determined by an R7999
commissioning parameter (even though the burner control
may have a different actual postpurge time.
Wait-XXX—the R7999 has detected an unusual input
condition at its LCI, HF, LF and MV inputs that is not part of
a normal sequence of operation. It is in a hold condition in
which it keeps LCO turned off, and waits for the condition
to be resolved. The “XXX” part of the status message
describes the inputs that are on; for example in the
abnormal condition where the MV input is on even though
LCI is off, the displayed status will be “Wait-MV”.
M20042
Fig. 6. Display module LINE2 area
during display initialization.
After the display is first energized or connected, it must wait to
receive 15 different configuration information records from the
R7999 before it is fully functional. Although the R7999
transmits its active status once per second, it transmits a
complete set of its configuration information (which does not
change) at a much slower rate, sending only part of it each
time that it transmits a message.
When the display is initially powered up or connected to an
R7999, it shows a spinning line to indicate that it is actively
receiving these initial messages, and it shows a countdown
value that goes from 15 to 0, indicating the progress in
receiving all of the information that it needs. When the last
information record has been received and the countdown
reaches zero, then the LINE2 field reverts to its normal
function of describing the second line, and the up/down scroll
prompt appears in the lower left corner of the display,
indicating that scrolling is now possible.
In addition to the configuration information records, the R7999
also transmits information about the points on the fuel/air/FGR
curve. These records are ignored by the S7999, but they do
interrupt the countdown process. While the point information
records are being received (and ignored), the spinning line
changes to a display of letters (A, B, C, ..., for example) and
the countdown holds. There will be as many letter codes as
there are points on the curve.
During normal operation, after the display has finished its own
initialization, the LINE2 area shows one of the following:
Blank—when the LINE2 area is blank then the display is
showing an item from the top-level menu in its second line.
IO—Input/Output: the display is showing an item from the
Input/Output submenu in its second line.
MS—Motor Settings: the display is showing an item from
the Motor Settings submenu in its second line.
CS—Configuration Settings: the display is showing an
item from the Configuration Settings submenu in its second
line.
H1...H6—Fault History: the display is showing an item
from the Fault History in its second line. H1 is the most
recent fault and H6 is the oldest fault.

S7999 CONTROLINKS™ DISPLAY MODULE
Air-Fuel-FGR
Pushbuttons
This area of the display shows the current positions of the
actuators as a percentage of their closed-to-open range, from
“00%” to “100%”.
The two lefthand (SCROLL) pushbuttons scroll the second
line up and down through a list of menu items.
The third pushbutton (
A--%—shows the air actuator position.
) provides a toggle function.
F--%—shows the position of the currently selected fuel
actuator.
The fourth pushbutton (
function.
) provides a change level
R--% or H--%—shows the position of the FGR actuator. If the
system does not included an FGR actuator, then this item is
blank. The “H” indicates that an FGR hold (an option enabled
during commissioning) is currently active because the R7999
XmA input is (or has been) below the Enforce threshold and
has not yet crossed the Release threshold, whereas “R”
indicates normal, no-hold FGR operation.
In the top-level menu, an item that provides access to a
submenu is indicated by a right-pointing arrowhead ( )
following the submenu description (Inputs/Outputs, Motor
Settings, Configuration Settings, Fault History and Line 2
Legend). Pressing the change level button when a submenu
description is displayed will shown the first item of submenu
information and will cause an identifier for the submenu to
appear in the LINE2 area in the top right corner of the display.
Each submenu item has a left-pointing arrowhead ( ) to
indicate that the change level pushbutton may be used to exit
the submenu and return to the top-level menu. In the top-level
menu, the LINE2 area is blank.
The toggle button cycles the second line of the display
between the main display and whichever second line was
most recently shown by using the scroll and change level
pushbuttons. This provides a way to quickly return to the main
display. The toggle button may also be used to compare the
main display to some other item by quickly toggling between
them.
NOTE: If the display has just been powered up, or if the
scroll buttons have been used to return to the main
display, then there is no other second line as
described above for the toggle pushbutton. In this
case the Run Time item from the top-level menu is
used.
The top-level menu and each of the submenus wrap around,
that is, scrolling down beyond the last item causes the first
item to appear; and scrolling up beyond the first item causes
the last item to appear.
The pushbuttons are disabled while the display is starting up.
An up/down arrow indicator appears in the lower left corner of
the display after initialization is complete and the buttons are
enabled.
All of the selectable second line messages are shown in
Table 3. Submenu items are shown indented under their
top-level menu description.
