are not used should be set to this step type in order to prevent
unnecessary switching operations and alarms.
Flty
= Step was switched three times without success and identified as
defective. This is not used for the control anymore. Defective steps are
flashing in the step display.
Steps which are set to the step type “
Flty
” can be switched back to the desired
step type in this menu.

Switching cycle counter (step 1
…max)
0...500000
The switching cycle counter of a step is increased by 1 for each complete
switching operation (switch-on and switch-off) of the affected step.
The switching cycles of the steps offer conclusions to the condition of the
capacitor contactors.
If the service alarm is activated (Setup/506 = YES) and if the switching cycle
counter of a step exceeds the set limit (Setup/507), the
OPC
alarm (max.
switching cycles) is triggered and signalled.
If, e. g., the power contactor of a step has been changed, the switching cycle
counter for this step can be set back to "
0
" in this menu in order to restart
monitoring. In this way, an active
OPC
alarm is reset.
If several steps of the same size are connected and the option “
Distribute
switching operations of the steps via the operating hours of the
individual steps
” is deactivated (SETUP/315 =
NO
), the controller
automatically distributes the switching cycles for these steps based on the
switching cycle counters so that each of these steps has the same amount of
switching operations (+/- 1).
405
Operating hours counter steps (step
1…max)
0...65500 h
The operating hour counter of a step is working while the affected step is
switched on.
The operating hour counter of a step offers conclusions to the condition of the
running time and the condition of a capacitor.
If the service alarm is activated (Setup/506 = YES) and if the operating hour
counter of a step exceeds the set limit (Setup/509) by 1 h, the
OPHS
alarm
(max. operating hours steps) is triggered and signalled.
If, e. g., a capacitor has been changed, the operating hour counter for this step
can be set back to "
0 h
" in this menu in order to restart monitoring. In this way,
an active
OPHS
alarm can be reset.
NOTE:
Operating hours can only be entered as full hours.
If several steps of the same size are conn
ected and the option “
Distribute
switching operations of the steps via the operating hours of the
individual steps
” is activated (SETUP/315 =
YES
), the controller automatically
distributes the switching operations for these steps based on the operating
hour counters of the individual steps, so that the operating hours for these
steps are distributed evenly.
