EEM accessory - Energy Meter
The EEM accessory allows certain unit features, such as those below, to be measured and displayed:
- Power supply voltage and instantaneous current consumption of the unit
- Instantaneous electric power consumed by the unit
- Instantaneous power factor of the unit
- Electricity consumption (kWh)
If the unit is connected via a serial network to a BMS or external supervisory system, the trends of the measured parameters can be stored and the
operating status of the unit itself checked.
Attention: in order to use the EEM accessory, the unit must be powered with 400V-3ph + N - 50Hz
FDL accessory - Forced download compressors
The FDL accessory (forced reduction of the power consumed by the unit) allows power consumption to be restricted according to the utility requirements.
The user can set the desired percentage on a special mask. The function, which can be set from the unit display, can be enabled via a digital signal,
using time bands or as an input in the case of a serial connection with an external BMS via Modbus.
