• Parameter S68
- characterizes function of R6 reserve output similar with S6 and S14 parameters
with instaled AC07X-C additional module. Primary is this reserve used to control electic valve for
pellet burner pneumatic ash cleaning system....... (16) .
Function is also for DxxPX (PXxx) boilers, burner profile A25PX (A25PX pneu)
if:
a)
S68
= 1
…. If any fault occurs in the burner and the burner is shut down,
the reserve relay will
be closed and the reserve output will be energized. Thanks to this you can start a spare source
of energy for heating of the building as e.g. a gas, electric or oil boiler.
b)
S68
= 2 ….. If any fault occurs in the burner and the burner is shut down , the reserve relay will
be opened and the reserve output will not be energized.
Thanks to this a signal can be sent to an
electrically backed up AB01 ATMOS GSM module controller that will send information that there
is a system fault or the system is not energized. This is the opposite logic (to S14 = 1), which
means that during normal operation the reserve is energized.
c)
S68
= 3
…… The reserve
function as the output function for the burner fan
, when the re-
serve output is closed, is energized always when the burner fan is running (fan mode only
100 % or OFF). This function is applied if you want the boiler fan or extraction fan in the chimney
to run together with the burner fan. This function is designed for direct control of an fan directly
from the burner (e.g. DxxPX, PXxx).
d)
S68
= 9 ….. Reserve function as the output function for the external worm conveyor, when
the reserve copies the run of the external worm conveyor, but with the difference that it does not
cycle, but runs permanently both during the drawing of the ignition amount and during both
the times T4 and T6. Thus, the other external conveyor runs continuously and works indepen-
dently
of the status of the actual output for the external worm conveyor. This means that if the
output to the main external conveyor from which pellets directly fall to the burner gets damaged,
the reserve will keep working independently . This function can be used in cases when you need
to control another external conveyor that supplies (feeds) pellets from a larger distance to a pel-
let bin at the boiler from which the main external conveyor draws pellets to supply them directly
to the burner.
Caution
- the other external conveyor must always be controlled with an additional
level sensor (level meter) that will maintain the level of pellets in the pellet bin at the boiler.
e)
S68
= 10 ….. Reserve function as the output function for the external worm conveyor, when
the reserve copies the run of the external worm conveyor, but with the difference that it does not
cycle, but runs permanently both during the drawing of the ignition amount and during both
the times T4 and T6. Thus, the other external conveyor runs continuously, but it works in de-
pendence on the status of the actual output for the external worm conveyor. This means that if the
output for the external conveyor from which pellets fall directly to the burner gets damaged, the
reserve will be switched off automatically. This function is convenient in cases when you need to
control another external conveyor that supplies (feeds) pellets
from a larger distance to a pellet
bin at the boiler from which the main external conveyor draws pellets to supply them directly to
the burner. Caution - the other external conveyor must always be controlled with an additional
level sensor (level meter) that will maintain the level of pellets in the pellet bin at the boiler. This
is a similar function to S6 = 9, but with a higher degree of safety.
