Figure 27: Single-phase installation with 3 loads to connect (Load 1 Connected).
In this situation the CDP-G maintains the system without adding or removing any
loads for a time equalling the longer of the configured “Reconnection time” and
“Min. disconnection time” variables, in order to achieve system stability (in this
case 5 minutes).
To check if this load must be disconnected, the CDP-G waits for the amount of
time programmed in the “Min. connection time” variable and then checks if the
following condition is met:
• Disconnection condition:
𝑷𝑷𝑷𝑷𝑷
∑ 𝑷𝑷𝑷𝑷𝑷𝑷𝑷𝑷𝑷𝑷 𝑷𝑷𝒓𝒓𝒓𝒓 < 𝑀𝒓𝒂. 𝑷𝑷𝑷𝑷 𝑷𝑷𝑷𝑷𝑷𝑷𝒐𝒐𝑷𝑷𝑷𝑷
(

= 0%)  0% ≤ 50% 
this condition is met
 relay 1 stays connected
Then, the CDP-G will check whether it can connect the next load. To do so, it
must verify whether the 2 connection conditions are met:
• Condition 1:
𝑃𝑃𝑃𝑃𝑃𝑃𝑃𝑃𝑃
