Triggering of relay
Options:
•
only if calculated change: This is the recommended standard setting.
Just as with the existing range of ABB i-bus
gered to switch the Energy Actuator when the calculated relay position diverges from the received switch-
ing telegram.
Example
The contact is already opened, one of the functions of the Energy Actuator, e.g. function Staircase
lighting or Threshold value, triggers a further OFF telegram. In this case, the relay is not controlled
again, as the required relay contact position already exists.
•
always: This selection should be chosen if it is not possible to exclude that the relay is manually
switched and the required relay contact position must be guaranteed. The switching telegram is then
always undertaken regardless of the calculated position. The disadvantage is if, for example, the
same switching telegram is always received cyclically, the switching impulse is internally enabled and
the following switching telegram is undertaken with a delay (in the most unfavourable case up to 1 s).
Delay for interpretation
Options:
The interpretation delay applies for contact monitoring, all instrument and all power values from output A. It
starts with each switching impulse even when the relay position does not change. No communication ob-
jects are updated or sent during the interpretation delay; monitoring by the threshold values only com-
mences after the parameterized time has timed out. This prevents an undesired reaction of the Energy Ac-
tuator should a threshold value be briefly exceeded due to settling actions or the start-up behaviour of
load.
The minimum duration of 100 ms results because the Energy Actuator requires a certain amount of time
before all measured values are available.

Inverted
Options: no: 0 = open, 1 = closed
yes: 0 = closed, 1 = open
With this parameter, the status response of contact position can be inverted.
•
0 = open, 1 = closed: The value 1 is written with a closed contact, and the value 0 is written
with an open contact in the communication object Status switch.
•
0 = closed, 1 = open: The value 0 is written with a closed contact, and the value 1 is written
with an open contact in the communication object Status switch.
