times, this step will be skipped by the control. Steps which have been switched off by the alarm
system via the step switch-off sequence and have been locked for max. 30 min. are also skipped.
If steps which have been identified as defective are not locked, the function “
Lock faulty steps
”
(SETUP/309) must be deactivated. Otherwise, the affected step will be switched on and off
unnecessarily.
!
CAUTION
The defective step is switched on and immediately switched off again. If the control target has not
been reached yet, the affected step is continuously switched on and immediately off again in the
cycle of the switching time. The control hunts.
The combi filter algorithm only works with capacitive steps.
If the step identification is executed for the first time, more step power may be switched on at the
even switching outputs than at the odd ones. Enter the step sizes manually (SETUP/402) in order
to avoid this.
Be careful when you define FON steps.
By setting FON steps, more step power may be switched on at the even switching outputs than at
the odd ones.
NOTE:
The step exchange function and the switching distribution (switching cycles or operating hours)
are always deactivated in case of steps of the same size.
NOTE:
It is not possible to switch the steps manually.
18.4 Progressive
Works like the
“BEST-FIT”
algorithm, with the exception that the controller switches on and off
several steps one by one with a shortened switching time, if necessary. The set switching time is
ignored in the process.
The step sizes must be entered manually, because the step identification is always deactivated in this
algorithm. The entry should be as precise as possible, because the control will otherwise tend to hunt.
Steps with the step type “
FON
” and “
FOFF
” are skipped by the control. Steps which have been
switched off by the alarm system via the step switch-off sequence and have been locked for max. 30
min. are also skipped.
NOTE:
The step exchange function and the step identification are always deactivated. An updating of
the step sizes, an identification of defective steps and an identification of power loss of the individual
steps by the control are not possible.
18.5 FIFO
“First IN, First OUT” (cyclic control): The controller starts with step 1 and switches on the step of the
next higher number each time, if necessary. When switching off, the controller starts with step 1 and
switches off the step of the next higher number each time, if necessary. If steps 3 to 7 are still
