Activate Step exchange
Yes/No
"YES" for an optimal compensation result, the controller can switch
off active steps and replace them with more suitable steps.
"NO" This function is deactivated.
This function is useful when different step sizes are available. If all
available step have the same step size, then this feature should be
disabled otherwise is may lead to unnecessary switching cycles.
308
Step recognition "OFF"
Yes/No
"YES": Step sizes have to be programmed by hand. The step sizes
have to be programmed by hand if:
a) there is in the system quickly changing loads and problems
with the automatic step size detection occurs.
b) the automatic detection of defective steps is not desired.
c) the contactors have a delay of more than 200msec.
"NO" Step sizes are automatically determined during operation and
losses of step sizes were tracked and considered at the control.
309
Blocking of defective capacitors
Yes/No
"YES" If a step is switched in three times without measurable
network reaction, the controller is blocking the step and doesn't use
it for the control.
Is a Step recognized to be defective, blinks in the display the
corresponding output and in the step database and menu "403" it's
displayed as step type "flty".
"NO" Steps are connected even if no network reaction is
measurable. This results unnecessary switching cycles.
Steps that are stored as defective will be tested every 24 hours or
after the controller is restarted.
310
Start / Stop / Hold PF-control
On/Off/Hold
Stopping the automatic control. The following options are available:
On:
Control in automatic mode
Off:
Control stops and active steps were disconnected successive
Hold: Control Stops and active step's remain switched on.
If "OFF" or "HOLD" is selected, will appear in the display "PFC"
alternating with "OFF" or "HOLD". To start the control, select
"ON".
