Tariff setup

You can change tariffs and the tariff mode using the display and/or ION Setup .

You can change the tariff mode using the display. You can configure input mode and time of day mode using the display or ION Setup . It is recommended that you use ION Setup to configure time of day mode.

The active tariff is controlled based on the tariff mode.

  • When the meter is set to command mode for tariffs, the active tariff is controlled by Modbus commands sent from your energy management system or other Modbus master.

  • When the meter is set to input mode for tariffs, the active tariff is controlled by the status of the digital inputs.

  • When the meter is set to time of day mode for tariffs, the active tariff is controlled by the day type, the start and end times, and the start and end dates.

Time of day mode tariff configuration considerations

The time of day tariff is not a calendar; the meter does not calculate the corresponding day of the week to a specific date, but February 29th is considered a valid date if you are programming the meter during a leap year.

When you enter tariff times using the display, be aware that the displayed minute value includes the entire minute. For example, an end time of 01:15 includes the time from 01:15:00 through 01:15:59. To create a tariff period that starts right after this, you must set the next tariff’s start time to 01:16. Although it may appear that there is a gap between these tariffs, there is not.

NOTE: You must always set the tariff times to UTC (GMT, Greenwich Mean Time), not local time. The GMT Offset (h) setup parameter does not apply to tariff times.

Input mode tariff configuration considerations

Digital inputs are available for tariffs if they are not used, or if they are only associated with alarms (Normal). To make a digital input available, you must manually disconnect the conflicting association before configuring tariffs.

NOTE: You must always set the tariff times to UTC (GMT, Greenwich Mean Time), not local time. The GMT Offset (h) setup parameter does not apply to tariff times.

To configure the tariffs using ION Setup , see the “PM5500 / PM5600 / PM5700” topic in the ION Setup online help or in the ION Setup device configuration guide, available for download at www.se.com .
