the tightening channel is enabled:
• Position n K (multi-channel, standard),
NH: The motor contactors are controlled
centrally via the XDN2 interface on the
VM350 power supply module (see also
manual on the 350 power supply module,
emergency OFF for stationary tightening
systems and for hand-held nutrunners).
• Position 1 K (single-channel, special
version of the connecting cable
necessary): The motor contactors are
controlled via the XDS2 interface on the
LT (optional for hand-held spindles).
