Technical requirement and wiring update
On June 24, 2026, LONGWELL opened a project to update drawing documentation for the LWCD-60870MN-06 cross flow fan. The update transitioned the motor lead setup to a standard four-wire configuration by adding a frequency generator (FG) tachometer signal wire.

The revised engineering drawing details the motor connections as a four-lead cable bundle (4Cable L=500 mm) for 24V DC power, FG signal output, and 0-10V speed control.
Documented fan specifications
The updated assembly drawing documents structural dimensions and electrical design ratings for the LWCD-60870MN-06 model as specified below.
| Parameter | Documented Specification Value |
|---|---|
| Rated Voltage | 24 VDC |
| Current | 1.25 A |
| Speed | 1800 r/min |
| Air Volume | 693 m³/h |
| Bearings | Ball bearing |
| Speed Control | 0-10V |
| Overall Length | 930±2 mm |
Engineering output
The technical output provides an updated cross flow fan drawing incorporating the 4-wire lead layout and FG tachometer feedback wire to support customer evaluation and integration.
