CLEANING CYCLE
PAR48
0...250 min
BURNING time between two CLEANING cycles. If set
to 0 then CLEANING is turned off. If BURNING has
been longer than 2x PAR48 set, then extraordinary
cleaning will made.
GRATES CURRENT

Linear motors maximum current level. If greater, then
motor is stopped and cleaning cycle is started again.

At the
LOADING
cycle, external auger is turned on. When pellet level in the burner reaches to level
sensors, internal feeder is started. Feeder auger loads necessary amount of fuel needed for ignition into
burning chamber. Amount of loaded fuel is measured by counting the rotations of feeder auger.
LOADING cycle is ended when feeder auger has made exact number of rotations pre-set in PAR24.

At the
LOADING
time, external auger holds permanent fuel level in the feeder auger’s tube. Depending
on the level sensor signal, the external auger is turned on or off.
Feeder auger’s work depends also on fuel level sensor signal.
Maximum loading time is limited by 20 minutes after manual (initial) start up 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 to other external auger. In single pellet container delivery system NO PELLETS error will occur.
