ü To set the [Conveying edge]:
a) Enter the width of the conveyor supports (length of chain pins) in [mm] into
the input field.
ð The travel range of the soldering units is limited by this value in order to pre-
vent a collision between the solder nozzle and the conveyor chains. The dia-
meter of the solder nozzle is therefore taken into account. If a conveyor chain
is used with longer chain pins, you need to adjust this value.
