In order to work correctly, each load control must be connected to an ENERGY COUNTER. In order to achieve this, please
follow one of the steps below:
•
Either use an existing ENERGY COUNTER (check out previous chapter) and drag it into the corresponding section
of the load control
•
Or create a new ENERGY COUNTER by using the ADD button
In both cases the connected object is shown in the section „ENERGY COUNTER“ and beneath its name also the result of
an automatic control (check) is shown, which assures that the used ENERGY COUNTER was configured correctly in order
to work in combination with the load control.
The following parameters must be configured correctly within the ENERGY COUNTER in order to be used as reference
object:
•
Power value (either directly or using the power calculation, as seen before)
•
Minimum and maximum power limit, either as “static” value or as sub-objects
•
Sub-object “priority”
Preferably also the sub-object “Load over limit” should be configured, which is automatically set to 1 if the logic of the
load control is enabled and starts switching off loads, and is set back to 0 as soon as the total load falls back under the
configured limit.
If the load control is active, the value connected as „POWER – MEASURED VALUE“ within the ENERGY COUNTER is used
as reference; if this value surpasses the configured limit, the load control logic is enabled (once the configured cycles
expire) and increments the priority value (in idle state = „0“) to 1; as a result, all loads that have been set to this priority
value will be turned off. This process is repeated as long as the total load falls back under the configured limits; until this
happens, the priority value is continuously incremented and the corresponding loads are switched off.
Once the total load falls back, the load control logic will work in the opposite way: as long as the load stays within the
limit, the loads are turned back on again in the inverted way, naturally always respecting the configured cycle times and
amounts.
