Pulse inputs and outputs (optional)
By meters with pulse inputs, the
pulse value can be called up in the
display (see the display overview,
level 4). The pulse value of the
outputs is permanently set and
corresponds with the last position of
the associated display value.
Typical connection (*)
(*) The connection of the external
resistor could be necessary to en-
sure an integrated current limiter.
Example:
Output 1 = energy output
Energy display = XXXXX.XXX
Last position = 0.001 MWh = 1 kWh
Output pulse = 1 kWh

M-Bus (optional)
The optional M-Bus interface com-
plies with standard EN 1434-3 and
operates with 2400 baud xed. The
two conductors can be connected in
any order to the M-Bus network.
A rmly attached cable is included,
external wiring must be done by
oneself.

Programming of M-Bus address
(optional)
■
Select of the display „Adr 000“ in
level 3 (same for the additional
inputs „Adr1“ to „Adr3“).
■
Press the button for about 2
seconds (until the door symbol
reappears) and then release. The
right digit starts ashing. With
one short push the value of the
digit is incremented.
■
With each long press, the selected
value will be taken over and
change to next digit (as soon as
desired character ashes, release
the button).
■
If the desired value is reached,
you have to press the button
until the number stops ashing
and the return to the menu is
completed. Now the new value is
programmed.
■
The programming process can be
repeated if necessary.
Note: If the editor is not terminated,
maybe changed values are being
saved aer the automatic return to
the main display.
