This communication object is always enabled. It indicates that the measurement electronics of the Energy Actuator are
"working". The value of the communication object is sent on a change and when a telegram is received on the communication
object Request status values.
The measurement section is supplied with power from one of the output circuits A...C.
If the rated voltage (see Technical data) is present on at least one of the outputs, the measurement values are recorded and
are available on the KNX side.
Telegram value:
10
This communication object is enabled if in parameter window Function, page 35, the parameter Enable object "Receive load
shedding stage" has been selected with the option yes.
This communication object is required for load control, as soon as the function Enable function load control slave has been
enabled on at least one of the outputs and the shedding stage is received via the bus (from an Energy Actuator that is parame-
terized as a load control master or, e.g. by a visualization system). If the Energy Actuator itself is the master, the shedding
stage can also be internally linked (parameter window X: Load control slave. Parameter Slave is controlled via option Receives
load shedding stage internally.
If a parameterized Load shedding stage output is received at Output A...C, the respective output switches off The shedding
stage is received once per device and is valid for all outputs parameterized as a slave.
Format:
8 bit
D (bit 7):
P (bit 6...4) [000b...111b]: If more than one master is available in the system, these bits can determine the priorities of the
S (bit 3...0) [0000b-1111b]: This is the actual shedding stage.
Telegram value:
Shedding stages 9 to 16 are not used with the Energy Actuator.

Function
Measurement circuit active
1 = On at least one (any) output of the Energy Actuator rated voltage is present,
measurement values are recorded.
0 = No rated voltage is present on any of the outputs, measurement values are not recorded.
