Figure 3.3, REMOTE WIRING CABLE
The remote start function requires a signal of +5 to 24 VDC. This signal is applied to pin C of J3. The common
is from the DWF–3 (this signal is optically isolated from the DWF–3); therefore, the signal common need not
be attached to the control unit ground. This signal would normally come through the normally open contacts of
a relay that is activated at the start of a weld cycle, for example, the Seam Tracker interface relay.
The inhibit function requires a signal of +5 to 24 VDC applied to pin E of J3, and common connected to pin G of
J3. The inhibit signals are optically isolated from the DWF–3 control unit, and the common need not be
connected to the control unit ground.
