switched on, the control starts with step 8 when switching on. If step 12 has been switched on and
step 1 has not yet been switched on, the control starts with step 1 next. When switching off, the control
starts with step 3. If step 12 has been switched off and step 1 is still switched on, the control starts
with step 1 next. It is checked individually for each step, if the switching operation is useful. This may
lead to an unprecise compensation in case of steps of different sizes.
Blocked defective steps (
“FAULTY”
)
and 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.
If a step is identified as defective and blocked (
“FAULTY”
) after being switched on 3 times, this step
will be skipped by the control.
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.
These steps are switched on and immediately switched off again and skipped by the control. The next
step is used for switch-on. When switching off, blocked defective steps are also skipped. The defective
steps will again be switched on and immediately switched off again and skipped during the next cycle
of the cyclic control.
Example:
Steps 12, 1, 2, 3, 4 are switched on, step 5 is defective and not switched on. When switching on, step
5 is switched on and immediately switched off again. Step 5 is skipped and and step 6 is switched on
instead. Steps 7, 8, 9, 10, 11 are switched on normally one by one. When switching off, the steps 12,
1, 2, 3 and 4 are switched off. As step 5 is defective and was already switched off, this is skipped and
step 6 is switched off next. Steps 7, 8, 9, 10 and 11 are switched off normally one by one. Step 5 is
switched on and immediately switched off again and skipped during each cycle of the cyclic control for
as long as the function “
Lock faulty steps
” (SETUP/309) is deactivated. If the function “
Lock faulty
steps
” (SETUP/309) is activated, step 5 is not blocked until after the third switch-on attempt and
skipped automatically during each cycle of the cyclic control.
NOTE:
The step exchange function and the switching distribution via the switching cycles or the
operating hours) are always deactivated in case of steps of the same size.
NOTE:
It is not possible to switch the steps manually.
