3- VERSION 3.0
The Merlin 3000 series unit is designed for
Press Brake operations especially where
programmable back gauge systems are
used. The Merlin light curtain is useful
when the part to be bent is large enough to
extend into the light curtain beams. It can
be taught the profile of the part when
making the first part. The part profile pattern can then be run from temporary
memory and / or stored for future use.
Only the bottom three inches can be permanently blocked. This allows for a work
support table or arm. The rest of the beams
are not permanently blocked.
! WARNING

FUNCTIONS, CARE MUST BE TAKEN
TO TRAIN THE OPERATORS IN THE
CORRECT METHOD TO HOLD
PARTS SO THAT BOTH HANDS ARE
OUTSIDE THE LIGHT CURTAIN
PLANE AND KEPT AT A SAFE

beams may be blocked without causing a
hazard condition. Blocking more than the
allowed number will cause the output to of

the floating function only works within the
limits. Interrupting any number of beams
outside the limit will cause a hazard
condition.
