With
key 3 you scroll
to the indication of
real power EMAX.
Real power EMAX

Measuring period
(Example
15Minutes).
Reset of the measuring period
The averaging time for real power Emax is called
measuring period.
The measuring period for real power Emax can be
5, 10, 15, 30 and 60 minutes. The manufacturer’s
setting is 15 minutes.
To be synchronized with the measurement of the
energy supplier, the reset of the measuring period
should be carried out via an input of UMG 505. If no
reset via an input of UMG 505 occurs within the pro-
grammed measuring period, the reset is released
automatically by the internal clock.
The reset of the measuring period deletes real po-
wer Emax and starts a new measuring period. The
last measured real power Emax is used for the
minimum and maximum storage and, if program-
med, saved in the event memory.
If there are less than 30 seconds between two
resets, the measuring period is reset and real po-
wer EMAX is deleted. The obsolete measured value
is not saved in the maximum and minimum memory
and
not
be deposited within the event memory, if
programmed.
The measuring period for real power EMAX can be
reset by the following means:
- automatically, after measuring period,
- internally, via keyboard,
- internally, via digital inputs,
- externally, with MODBUS Protocol,
- externally, with LON Bus.
The automatical reset after measuring period can-
not be suppressed.
Press
key 1 for about 2 seconds and you return to
the first measured value window of the measured
value indication from each program part.
