Addendum to:

LaserGuard2 Collision Avoidance System Instruction Manual (147-20004)
Parts of an older LaserGuard system and a new LaserGuard2 system can be used together and function
properly, but it may require slight adjustments to the wiring or trip point set-up.
If an old Laser Support Unit is used with a new LaserGuard2 laser head, adjustment from the existing
cable to the control board would be required, as the laser pin out has changed. See the table below on
how to wire with the old system versus the new system. The potentiometer may require fine-tuning as
well.
If an old laser head is used with a new LaserGuard2 Laser Support Unit (LSU), wiring would also have to
be wired using the table below. The LASER SELECT switch S4 on the control board of the LSU must be
moved from the default position of “ON” to “OFF”. This will prevent nuisance Overcurrent faults when
moving the crane to distances approaching 150 feet.
