Loading
In the “Loading” cycle, pellet auger is turned on. When pellet level in the burner reaches to level sensors,
internal feeder is started. Feeder loads correct amount of fuel into burning chamber needed for ignition.
Loaded fuel amount is measured by counting internal feeder rotations. Loading cycle is ended when
feeder is made correct amount of rotations, fixed in parameter nr.24 (loading feed rot.)

Par 24 Loading feed 35..40 rot Feeder rotations neede to load pellets into
burning chamber. Depends from burner model.
Par 25 Loading 2 feed 5 rot Feeder rotations for second loading.
- Max loading time 5 min Maximum regular loading time
- First loading time
after manual start
20 min Maximum loading time after manual start.
- Auger start 3 sec Auger Start delay if no fuel in burner
- Auger stop 3 sec Auger Stop delay if fuel in burner
- Feeder start 1 sec Feeder Start delay if fuel in burner
- Feeder stop 4 rot Feeder rotations made without fuel level before
stopped
At the “Loading” time, external auger holds permanent fuel level in the feeder tube. Depending of the
level sensor signal, the auger is turned ON or OFF.
Internal feeder work is also depending on fuel level sensor signal.
Maximum loading time is limited by 20 minutes after manual (first) start because extra time for external
auger filling is needed. In next loadings, maximum time is limited by 5 minutes.
If maximum loading time is exceeded and silo selection on burner is used, the pellet delivery will be
switched on other auger. In single pellet delivery system “No pellets” error will occur.
