35 - Load Shedding
Description
The
Load Shedding
function allows you to manage malfunctions on systems that can work thanks
to the energy produced by renewable and local energy sources, in particular a lack of power,
e.g. due to a malfunction on the MV voltage side.
The function is available in two versions:
Basic
is supplied with all Ekip Touch Trip units
Adaptive
can be purchased with the relative additional package that is available for all
Trip units equipped with the
Measuring Measurement
package, excluding Ekip M Touch
All the parameters and measurements of the function are available via Ekip Connect, while the
Trip unit allows setting and viewing some of them, as noted below.
IMPORTANT: for full details see the Technical Catalog (see page 4) or the
function's White Paper (see page 12).
