3.2 Programming page Easy Connection (EC)
Figure 8: EC screen
On this programming page the Easy
Connection (EC) function can be
activated/deactivated. This function is
used to determine whether or not the
energy flow direction is taken into
account. The EC function is activated
by default.
Figure 9: Case 1 (left): the energy flow in
the conductor is from K to L /
Case 2 (right): the energy flow in the
conductor is from L to K
Easy Connection activated (EC yes)
If Easy Connection is activated (EC
yes; Default yes) it does not matter if
the energy flow in the conductor is
from K to L (Case 1) or vice versa (Case
2). The power meter always calculates
with positive values (amounts).
Easy Connection deactivated (EC
no)
If Easy Connection is deactivated (EC
no) the energy flow direction
determines the algebraic sign of the
power. The algebraic sign of the power
is positive if the energy flow in the
conductor is from K to L (Case 1). In
the opposite case (Case 2) the algebraic
sign of the power is negative.
