LOAD CONTROL (OPTION)

Note: These pages are displayed only if the option LOAD CONTROL is
activated with the ACCESS code in the menu GENERAL (see par
par.11.3).
The load control function allows to switch off the load when the expected
average power exceeds the set value (Contract Power).
The setting in the menu AVERAGE –Type (see par. 11.5) allow to choose if
the expected average power is calculated at fixed or floating window.
Enable / Disable, for default is disabled (Disable), if enabled (Enable) the load control will be
activated, the standard and optional digital outputs will be used for this function and they lose each
other programming (i.e. pulse, threshold, etc.).
• Contract Power, indicates the threshold powers (contractual) expressed
in kW for each time band.
• Fixed Power, indicates the minimum fixed powers expressed in kW for
each time band that cannot be disconnected.
• Safety Limit, is a percentage reduction of the Contract Power. The loads
disconnection starts when an expected average power, for each time
band, exceeds this value.
Range: 0% (Contract Power) ÷ 50%.
• Intervention Limit, is a percentage of the Safety Limit. An average
power below this value does not determine the load disconnection in case
of exceeding the expected average power of the Safety Limit value.
Range 0% ÷ 100% (Safety Limit).
