User-Defined Pulse Counters

Presentation

Pulse counters are used to calculate the total and partial consumption of energy or the total and partial volume measured by a metering device with a pulse output:

• Energy meters: Measuring active, reactive, or apparent energy.

• Volume meters: Measuring volumes in cubic-meters.

The pulse output of the metering device must be wired to an IO module digital input, configured as a pulse digital input.

Each pulse counter calculates:

• The total consumption, not a resettable value.

• The partial consumption, a resettable value indicating the consumption since the last reset.

The partial counters can be displayed on:

• The FDM121 display.

• The IFE or EIFE webpages, only when the IO module is connected to a circuit breaker.

• A remote controller using the communication network.

The partial consumption can be reset from:

• The energy counter reset input. Refer to Energy Counter Reset.

• A remote controller using the communication network.

• The EcoStruxure Power Commission software.

The date and time of the last reset of the partial consumption is recorded.

If the pulse counter calculates active energy, the instantaneous active power is also calculated.

The consumption values are saved in non-volatile memory to prevent a data loss if there is a power loss.

The monitoring from a remote controller using the communication network requires a communication interface module (IFM, IFE, or EIFE interface).
