Additional Notes

Additional Notes 1:

Accuracy - Technical data

Please note that the DPM algorithm generally performs compression over several waves. This can lead to limitations in accuracy, especially for signals with a period duration over more than one mains wave (e.g. wave packet control).

Additional Notes 2:

Measuring transformers

Suitable measuring transformers for use with the energy and power measuring terminals are available with the SCT series from Beckhoff.

Additional Notes 3:

Non-volatile storage of the energy values

All energy values are stored non-volatile in all EL34xx terminals even in case of a sudden voltage loss.
After switching on again, the energy values are at the level before the voltage loss and are counted on from there.

Notice

Accessory recommendation (BZ32xx) for terminals with potentially hazardous voltages

When connecting potentially hazardous voltages to terminals of the ELxxxx and KLxxxx series with standard wiring, Beckhoff recommends using the insertable, transparent labeling cover BZ3201 with the laser-engraved lettering “HIGH VOLTAGE” or the unlabeled version BZ3200.
