Screens for "+kWh" and "-kWh" Setting
Pulse/kWh
logic negative
Counter pulse to measure the real energy
positive/negative
The output of the kWh pulse (inductive as well as capacitive) may occur both nega-
tive (per kWh pulse the Open Collector output [terminal 60/61] is opened) and posi-
tive (per kWh pulse the Open Collector output [terminal 60/61] is closed).
Active energy
Pulse/kWh 000.0
Counter pulse of the active energy
0.1 to 150.0
The number of the pulses/kWh can be entered in this screen.

on? YY
Activate kWh display
Y/N
The kWh counter (positive real energy = [+]; negative real energy = [-]) is calcu-
lated by this parameter being enabled. This function is not required for the control
unit to operate properly. If this parameter is configured as "N", second line of the
display does not occur in the automatic mode.
Display kvarh +-
on? YY
Activate kvarh display
Y/N
The Kvarh counter (inductive re-active energy = [+]; capacitive re-active energy= [-
]) is calculated by this parameter being enabled. This function is not required for the
control unit to operate properly. If this parameter is configured as "N", second line
of the display does not occur in the automatic mode

Y/N
If this parameter is configured as "ON", the energy counter may be reset to zero by
pressing the pushbuttons "Select" and "Digit
↑
" simultaneously.
NOTE
The kWh-counter is reset in automatic mode by ...
•
visualizing the kWh-counter in the lower display line and by
•
depressing the buttons "Select" and "Digit" for at least 5 seconds.
After successful reset, the screens will display “
0000.0 kWh
" and/or "
