Etrel Load Guard | User manual
|
In the
Load Guard Communication Status
window, the following
information that Load Guard is transmitting, can be viewed:
•
Total active power [kW].
•
Power [kW] and current [A] of phase L1.
•
Power [kW] and current [A] of phase L2.
•
Power [kW] and current [A] of phase L3.
If the connection with the Load Guard is not successful, or the connection
is interrupted, red dot will show at the Load Guard icon.
The Load Guard Configuration software windows should look as it is
presented on the following figure.
Figure 37: Configuration windows
During charging procedure on master charging station or any other
charging station of this cluster, the Load Guard would measure total
consumption current of the charging station and other loads and send the
data to the master charging station.
If total current, that Load Guard measures, surpasses the set limitation of
current (Max. building current), the master charging station will lower the
target charging current of all charging stations in the cluster. This will be
performed in a way that total current of all the charging station and other
loads will not surpass the set limitation of current.
Most of the electric vehicles can not charge with charging current of less
than 6 A. Because of this, in a case that the target current would be
lowered to less than 6 A, the charging would be temporarily paused.
Charging will continue when the Load Guard sends information that the
total consumption is lower that the set limit for more than 6 A.
