Feed system
Rotary agitator
Mode
▪ OFF: Rotary agitator with separate drive system is
deactivated
▪ Auto FULL / EMPTY: The boiler controller makes the
decision whether the bunker is full or empty based on
the measured current of the motor of the separate
rotary agitator drive, which gives the runtime of the
rotary agitator with separate drive.
▪ Bunker FULL: The runtime of the rotary agitator with
separate drive system is defined via the parameter
“Weighting of screw runtime when bunker
is FULL”
, regardless of whether the bunker is full or
empty.
▪ Bunker EMPTY: The runtime of the rotary agitator with
separate drive system is defined via the parameter
“Weighting of screw runtime when bunker
is EMPTY”
, regardless of whether the bunker is full or
empty.
Nominal current for rotary agitator
Setting the nominal current of the rotary agitator with
separate drive according to the identification plate on the
motor.
Bunker FULL at % of nominal current
Threshold value in % of motor nominal current from the
rotary agitator with separate drive above which a full
bunker is assumed.
▪ If the actual power consumption exceeds the set
percentage value of the motor nominal current, the
boiler controller evaluates this as a full bunker and the
control of the rotary agitator with separate drive is
defined via the
“Weighting of screw runtime
when bunker is FULL”
parameter.
▪ If the actual power consumption falls below the set
percentage value of the motor nominal current, the
boiler controller evaluates this as an empty bunker and
the control of the rotary agitator with separate drive is
defined via the
“Weighting of screw runtime
when bunker is EMPTY”
parameter.
Cycle time:
Cycle time for calculating the runtime of the rotary agitator
with separate drive system.
Weighting of screw runtime when bunker is FULL
The total runtime of all screws is added up within the cycle
time. This parameter defines the runtime of the rotary
agitator with separate drive when bunker is full in the next
cycle.
Weighting of screw runtime when bunker is EMPTY
The total runtime of all screws is added up within the cycle
time. This parameter defines the runtime of the rotary
agitator with separate drive when the bunker is empty in
the next cycle.
Rotary agitator at address
Indicates the output at which the rotary agitator drive is
controlled.
Minimum current monitoring active
▪ YES: A failure of measured phase is detected.
Service hours of rotary agitator
Operating hours of rotary agitator if rotary agitator has its
own drive.
