MERLIN 3000 SERIES
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
WHEN USING BEAM BLANK OUT 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 DISTANCE.

6- BLANKING
Auto
Auto blanking is not available on Merlin 3000 units.
Manual
Manual blanking is not available on MERLIN 3000 units.
Float
The floating beam mode allows one beam in 1” units and three beams on 1 / 2” units to be set to float. This means that 1 to 3 beams may be blocked without causing a hazard condition. Blocking more than the allowed number will cause the output to of open, stopping the machinery being controlled. If limits are set for the floating beams the floating function only works within the limits. Interrupting any number of beams outside the limit will cause a hazard condition.
