PFC
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".
CP1
COS φ 1
0.70 c ...0.70 i
This is the setting for target COSφ 1. It will be valid during normal
operation.
St
SWITCH INTERVAL
1...6500 s
The switch interval is the time delay between switching steps in
regulation.
The switch interval has two different functions:
1.
Protecting the contactors by reducing the number of
switching cycles.
2.
Building of the average of the reactive power in the time of
the switch interval.
Out
TYPE OF OUTPUT
With the exception of step type “flty” the follwing step types can be
selected:
Auto = Step is used for normal regulation algorithm.
Alarm = If the set temperature limit 1 is exceeded this step is
switched as fan output.
Fon = Step is permanently switched on (Step is still monitored
and shut down in critical situations).
Foff = Step is permanently switched off. Not used steps
should be adjusted to this type to avoid unnecessary alarm.
Flty = Step was switched three time without success and is
not longer used for automatic control.
As “flty” stored steps can be set to desired step type in this menu.
