3 System Operation
3.2 4 Curve Sets FMS (Option)
The FMS offers the optional facility for using 4 curve sets. In this case 2 curve sets are firmly
assigned to oil operation and 2 curve sets to gas operation. The curve sets are then selected
via terminal 75 (fuel selection) and additionally via the fuel safety interlock circuits.
* SIC = Safety Interlock Chain
Since the fuel safety interlock circuits now serve here for selection of the curve set, they are,
contrary to the standard flowchart, monitored immediately after starting (or more precisely af-
ter the end of t1, see flow charts) and must remain on until burner-shut-of.
3.3 Check Sums - Running Time Meter
Recalling the
Checksum and the
safety times Selector switch (1) to "Set-point feedback"
Press "Enter" (3) and keep pressed
- the checksum and the safety times appear one after the other on the display
Each of the parameter levels is safeguarded by its own checksum. The checksum for each
level and the safety and pre-ventilation times are displayed here in succession.
Order:
1
st
oil safety time in seconds
2
nd
oil safety time in seconds
1
st
gas safety time in seconds
2
nd
gas safety time in seconds
Pre-ventilation time in seconds
On the FMS without pilot burner the statement of the 2
nd
safety time contains safety time. The
statement of the 1
st
safety time is then irrelevant.
TIP:
If the parameter has been changed, the checksum will change , too, if a total reboot has been
proceeded or the duration of 1h has passed.
