c. Flame Signal/Failures:
Pressing the
Þ
key advances the display to screen
#4 shown in Figure 8.20. This shows the current
flame signal as well as the any flame failures which
may have occurred since the boiler was installed.
Since the boiler control has a short lag time
between receiving the flame signal and displaying
it, a flame signal log records the flame signal at
half second intervals during the last 2 seconds of
the ignition period. Press the
Þ
key to advance
through status screen #5 & #6. Screen #5 (Figure
8.21) shows the readings at 1.5 seconds (Meas. 1)
and 1.0 seconds (Meas. 2) before the end of the
ignition sequence. Screen #6 (Figure 8.22)
displays the readings 0.5 seconds (Meas. 3) and at
the end of the ignition sequence (Meas. 4). This
may be helpful to determine the cause of an
ignition failure.
d. Ignition Attempts:
Pressing the
Þ
key again advances the display to
screen #7 as shown in Figure 8.23. This screen
logs successful and failed ignition attempts. The
total of these two numbers is the number of
ignition attempts by the control.
e. Boiler Run Time:
Once again, pressing the
Þ
key advances to the
next status screen. Screen #8 (Figure 8.24)
displays the total run time of the control which
includes the total of all time that the control is
powered but not in Standby.
f.
Blocking Errors:
Blocking errors prevent the boiler from operating
until the condition causing the error is corrected.
When the error is corrected, the boiler will
continue to operate. Screen #9 shows the last
blocking error to occur along with the relative time
of the error (Figure 8.25). The error number in the
format E## corresponds to the English language
description at the bottom of the screen. A complete
list of Blocking Errors is provided in Table 10.1 in
the Troubleshooting section of this manual.
Pressing the
Select
key displays the same error,
as shown in Figure 8.26, but now shows the time
between this error and the previous error in its
history. In this case, the “0” in the upper right
corner is flashing to indicate that this was the last
error to occur.
Pressing the
Ý
key while the “0” is flashing will
show the previous error in the control history and
the number “1” will flash in the upper right. See
Figure 8.27.
The
Ý
key can be used to look at all 15 of the
blocking errors in the control history. When error
#255 is displayed (Figure 8.28), this indicates that
no errors occurred and the remainder of the errors
displayed will show this message.
