Connection Configuration; Correction Angle - janitza Prophi Operating Instructions Manual

Reactive Power Controller

Connection configuration

Prophi can be delivered
in two connection va-
rieties for the measure-
ment and supply volt-
age.
In the version measurement L-L, the measurement and
supply voltage must be taken from two outer conduc-
tors. In version measurement L-N, the measurement
and supply voltage must be taken between outer con-
ductor L and neutral N.

Correction angle

The controller Prophi indicates the power factor, real
and reactive power correctly, if current and voltage were
connected according to the type plate and connection
diagram. The phase shift between voltage and current
must not be corrected, and the correction angle is 0°.
The correction angle can be selected in the range of 0°
- 359° in one degree steps.
If the user cannot connect Prophi according to the
connection diagram, this can be corrected according to
the correction values of table 1 or 2.
Devices for version L-N can be corrected with the cor-
rection angles of table 1.
Devices for version L-L can be corrected with the cor-
rection angles of table 2.
If the connection fault is not known, the correction an-
gle can be determined automatically by using the " l earn"
function.

Example : Programming of the correction angle
The current transformer is installed in L2. "k-l" is not
exchanged. The voltage measurement is done accord-
ing to connection diagram between L2-L3.
Table: Correction angle
Voltage between
Current in L1-L2 L2-L1 L2-L3 L3-L2 L3-L1 L1-L3
L1 k-l 240° 60°
l-k 60° 240° 180° 0°
L2 k-l 120° 300° 240° 60°
l-k 300° 120° 60°
L3 k-l 0° 180° 120° 300° 240° 60°
l-k 180° 0°
In that case you can read the angle of 240° in the table
"correction angle".
Confirm selection with
key 1. One digit is
flashing.
Change the selected
digit using key 2. The
selected digit is flashing. Change the selected digit us-
ing key 3.
Leave programming mode with key 1. No digit is flash-
ing anymore.
With key 3 you continue moving through the expanded
programming.
