Tariffs

In addition to the total and partial energies, two independent tariffs can be managed for
energy measurement.
• The tariff is normally selected using the digital input but can be selected via the
communication protocol as an option.
• The TAR-A input function is available for selecting the two tariffs. Activate the TAR-A input
function to make the selection shown in the table:
The device has a programmable AC voltage input.
• The default function setting is TAR-A, which makes selection between tariffs 1 and 2
possible.
• The text tAr-1 or tAr-2 flashes to indicate the selected tariff and the increasing counter
reading.
• The counter readings for the tariffs are displayed as subpages of the system counters
(total and phase, if activated).
• For devices with Modbus, you can select the active tariff using a special command in the
Modbus protocol. You can find more information in chapter Modbus address table for
three-phase devices 80 A with Modbus interface (Page 91).
