ENERGY METER INDICATION
– There are five dedicated pages for energy meters.
• Imported and exported active energy
• Inductive or capacitive reactive energy
• Apparent energy.
– Each page displays the total and partial value (can be reset from commands menu).
– If the unit of measurement is displayed continuously, it means that the meter is for imported energy (positive). Display of exported (negative) energies can be enabled as well by setting parameter P02.09 to ON.
These energies are highlighted by the flashing of the unit of measurement and by the “-” sign, and are displayed after the imported energies by pressing
.
– If display of energy by individual phase is enabled (P02.10=ON), three independent additional pages, one per phase, will be displayed, including total and partial energy.
– If programmable input P13.01 is set to TAR-A, all the energy meters indicated are also present divided by Tariff 1 and Tariff 2. These meters are displayed in the system meter sub-pages (see Tariffs paragraph).
TARIFFS
– For energy metering, the DME D332 can manage 2 independent tariffs in addition to total and partial.
– The tariff is normally selected through the digital input, or optionally through messages sent through the communication protocol.
– To select the 2 tariffs, the TAR-A input function is available. Activating this makes the selection illustrated in the table:
– The device features a VAC programmable input.
– The default function setting is TAR-A, which therefore permits selection between the two tariffs 1 and 2.
– The text tAr-1 or tAr-2 flashes to indicate the selected tariff and consequently the meter reading that is increasing.
– The meter readings for the tariffs are displayed as a sub-page of the system meters (total and phase if enabled).
– The active tariff can be selected through a dedicated command on the Modbus protocol (see Modbus protocol technical instruction).
HOUR COUNTER INDICATION
– If the hour counter is enabled (see menu P05), the DME D332 displays the hour counter page, with the format indicated in the figure:
– There is a total hour counter and 4 partial hour counters that can be reset and activated with different sources (see the parameters of the P05 group).
