Using the item
Zero-point creator
, the controller can be activated via a zero point creator.
For energy supply networks with outer conductor connected to the earth potential, suitable control gear with
electrical isolation (e.g. voltage transformer) must be used.
These transducer adaptors (zero-point creator) are suitable for creating a virtual low-impedance neutral point
for the measuring device in a three-phase network without neutral conductor.
In the 700 V variant, this also serves to adapt the measurement voltage to the measuring device.
Make sure that the measuring devices are configured for the operation with a zero-point creator.
Transformers are available in the following variants:
Variant 400/100:
Primary:
400 V phase to phase voltage
Secondary: 100 V phase to phase voltage
Variant 700/100:
Primary:
700 V phase to phase voltage
Secondary: 100 V phase to phase voltage
4.13.1.2 Submenu
Target cosine
The target cosine submenu contains the following items:
1. Target cos
φ
for power consumption
2. Target cos
φ
for power recovery
3. Alarm cos
φ
(message when Alarm cos
φ
is not reached after set alarm delay time has elapsed)
For the items
Target cos
φ
for power consumption
and
Target cos
φ
for power output
a value from
inductive 0.80 to capacitive 0.80 can be entered.
If active power recovery is detected, this is signaled by the
a
symbol in the display.
Under the item
Alarm cos
φ
a value of inductive 0.50 to capacitive 0.50 can be entered.
4.13.1.3 Submenu
Stages
The Stages submenu contains the following items:
1. Auto configuration mode
2. Stage parameters direct input
3. Nominal values
At initial commissioning, the following window is displayed in the stage overview (item 2. Stage parameters
direct input):
