Installation and control: what to check

Mechanical

Mounting dimensions, inlet ring diameter, motor shaft height and terminal-box position of the LONGWELL LWBE3G630 are given on its dimensioned drawing. Compare them with the installed fan before ordering.

Electrical & control

The LONGWELL LWBE3G630 accepts a 0–10 V analog speed reference, PWM and Modbus RTU (RS485) control signals (per model; see the model datasheet). LONGWELL supplies its Modbus RTU register map with the fan so the BMS points can be re-mapped; the register addresses are not identical to the Ziehl-Abegg map.For other bus protocols, ask LONGWELL engineering for the integration options.

Performance

The measured P-Q curve of every LONGWELL model is on its model page; we check your duty point against it before quoting.
