MAIN FEATURES

• Start/stop commands for the generators via the PMCBus

• An internal synchronizer with voltage, frequency and phasedifferences control

• Management of active power setpoints for the generators, to allowthe gradual transfer of the load

• Management of power factor setpoints for the generators, whenoperating in parallel with the mains

• Fixed power control when in parallel to mains (BASE LOAD), with thepower setpoint for the generators adjustable by parameter or byanalogue input

• Variable power control when in parallel to mains (IMPORT EXPORT,or variable kW on the generators to guarantee a fixed power on themains), with power setpoint for the mains adjustable by parameter orby analogue input

• The loss of mains protections, to isolate the generators from themains in case of failure of the mains itself

• The LOAD SHEDDING function (non-priority load disconnection),with 4 available levels

• The PEAK SHAVING and PEAK LOPPING functions (start ofgenerators due to excessive demand of the load from the mains)

• Using the internal calendar clock (with rechargeable backup battery):

   • Periodical genset’s start-up with programmable rate (this testcan be done without load, in parallel to the mains or in islandmode by transferring the loads from the mains to the generators)

   • Selectable days and time intervals in which the generators mustnever be started

   • Selectable days and time intervals in which the generators mustbe started even if the mains is present

   • Periodical and ‘on-event’ history logs

• Embedded alarm sounder

• Multilanguage display (EN, IT, FR, PT, ES, RU)

EMBEDDED FUNCTIONS

The MC200 offers true RMS measures for:

• Mains voltages• Genset bus bars voltages

• Circulating currents

• Active, reactive, apparent power and power factor on the mains (totaland by phase)

• Active, reactive, apparent power and power factor on gensets busbars (total)

The MC200 is equipped with inputs and outputs, both digital andanalogue, all freely configurable, to meet the specific needs of theapplication.Thanks to the configurable AND/OR ‘Logics’, and a large and powerfulbuilt-in PLC it is possible to configure specific operating sequences foreach type of application.The controller is equipped with a large 4.3‘’colour graphic display, withicons and symbols, for a quick review of measurements (mains andgensets) and system status. It also allows the manual opening andclosing of both the mains circuit breaker (MCB) and the master gensetcircuit breaker (MGCB), via two dedicated buttons.
