Max. output HV modules
For setting the output power in watts of the HV module
used. If two modules are used, the output of one module
must be set here. If more than one module is used, HV
modules with the same output power should always be
used.
Startup criteria for HV modules - Flue gas temperature
If the flue gas temperature of the boiler exceeds the set
value, the HV modules are switched on. If the flue gas
temperature falls below the set value during heating mode,
the HV modules remain switched on.
Start ramp HV controller
As soon as the start-up criterion (parameter “
Start-up
criterion for HV modules - Flue gas
temperature
”) is reached, the high voltage is activated
with the start value (parameter “
Start value HV
controller
”). Within this set start ramp, the set times of
the parameters for standard operation (“
Interval
voltage increase HV module
” and “
Interval
voltage decrease HV controller
”) are reduced by
a defined factor in order to achieve a rapid increase in the
target voltage in the start phase.
HV cleaning system
Defines the type of cleaning system for the HV electrode of
the e-filter. Cleaning takes place either by means of
vibrator or air flush.
Number of cleaning cycles per heating hour
Determines the number of cleaning processes per boiler
operating hour in heating mode. Together with the
cleaning duration (parameter “
Duration of cleaning
cycle
”), the total cleaning time is calculated.
Example: Number of cleaning cycles per heating hour = 3,
duration of cleaning cycle = 3s, heating hours until
cleaning = 4 h,
Results in a cleaning time of 36 seconds (4 x 3 x 3)
Duration of cleaning cycle
Defines the total time for a cleaning process. During this
time the shaker is switched on.
Cleaning active during heating
▪ YES: When the time for cleaning is reached (parameter
“
Cleaning interval
”) and no blocking window is
active (menu System => Set => Cleaning), the HV
modules are switched off in heating mode. After a
pause of 15 seconds the electrode is cleaned and after
Cleaning active during heating
a further pause of 15 seconds the HV modules are
switched on again.
IMPORTANT: For the cleaning after switching off the
boiler, the cleaning in heating mode is taken into
account!
Example: Cleaning interval = 5 h; cleaning is carried out
after 5 h heating mode. If the boiler switches off in a
controlled manner after 7 h, the cleaning time of the
electrode is only calculated for the 2 h in heating.
▪ NO: The electrode is cleaned only after the boiler has
been switched off.
Cleaning interval
Specifies after how many operation hours of the E-filter a
cleaning cycle should be started.
Minimum target control for HV module(s)
Defines the output of the HV module up to which it can be
reduced in the event of flashovers. If the controller detects
a defined number of flashovers at the minimum setpoint
control, the HV module switches to standby mode for a
certain period of time.
Maximum target control HV module 1
Determines the maximum output of the HV module up to
which the voltage is increased in a defined interval
(parameter “
Interval voltage increase HV
controller
”).
Maximum target control HV module 2
Determines the maximum output of the HV module up to
which the voltage is increased in a defined interval
(parameter “
Interval voltage increase HV
controller
”).
Interval voltage increase HV controller
If the controller does not detect a flashover within this set
time, the voltage is increased by 1 percent.
Interval voltage decrease HV controller
A voltage reduction occurs after a flashover. Within the set
interval, the voltage can only be reduced by 1 percent. If at
least one flashover occurs again at the next interval, the
voltage is reduced again by 1 percent.
Start value HV controller
Defines the starting point of the HV controller start ramp
(parameter “
Start ramp HV controller
”).
Cyclone separator
Status
Cyclone separator operating mode
Displays the current mode of the cyclone separator.
Cyclone separator ash screw operating mode
Displays the current mode of the ash screw of the cyclone
separator.
