The step parameters are set in the step database. When the step identification is switched off, the
step size must be entered manually here for each individual step.

Discharge time lock
1...1200 s
Here, the discharge time lock is set globally for all steps. The discharge time
lock is a blocking time which is started after switching off a capacitor stage and
is running out. This is important, so that the capacitor is completely discharged
before it is switched on again. As long as the blocking time has not run out yet,
the respective step is not available for the control. The discharge time lock
should be adjusted to the discharge duration of the capacitors. This depends
on the discharging device.

When the automatic step identification is deactivated, the step size = step
nominal value must be entered manually for each individual step. The entered
step nominal value refers to the set nominal voltage. The value is entered
individually for each switching output.
NOTE:
If the step identification was concluded for a step or if the step size was
entered manually, the current step size with regard to the original step size is
displayed in % in the step database menu (INFO) for this step.
If the step identification was switched off and if the current transformer factor
and no step size has been entered manually yet, the control is switched off
(“OFF”) and the setting is locked. The setting remains locked until the current
transformer factor is entered once and at least one step size is entered
manually. Then, the control can be switched on again.
If the current or voltage transformer factor is entered subsequently
-
and the automatic step identification is deactivated, the current step
size of all steps is reset to the original value (entered value).
-
and the automatic step identification is activated, the current and the
original step size (the value which was accepted after the completion of
the step identification) of all steps is reset to the initial value of 3 var
capacitive. The step identification restarts again.

Step type (step

AUTO / FON
/ FOFF
The following step types except for the step type “
Flty
” can be set for each
individual step:
AUTO
= Step is active and is used by the control.
FON
= Step is permanently switched on (step is monitored
nevertheless and is switched off in critical situations).
FOFF
= Step is permanently switched off / deactivated. Steps which
