RMA-303 Direct Charge - Installation
LN-9266-11.3 40
MOUNTING
The RMA-303 is equipped with a quick discon-
nect assembly. The quick disconnect feature
consists of a robot plate which is permanently
attached to the robot through a wrist adapter
plate, and a mating bell plate which is a part of
the RMA-303 atomizer assembly. The atomiz-
er is secured to the robot plate with a threaded
retaining ring.
ELECTRICAL AND FIBER OPTIC CON-
NECTIONS
The fiber optic connection is made on the
back of the atomizer’s robot plate. The fiber
optic cable comes pre-assembled with con-
nectors that are secured in place by set
screws tightened from the side of the robot
plate. An adequate ground must be provided
to the mounting plate to ensure that fluid fit-
tings, etc. are at ground potential.
Maximum amount of splices for any length of
cable is 3, including the robot plate and trans-
ceiver card. The speed detection signal may
be affected if splices are exceeded. Length in
any combination for the fiber optic is 100-feet.
FLUID CONNECTIONS
The paint, solvent, and dump fluid tubing are
connected on the back of the robot plate with
stainless steel compression fittings and PFA
tubing. Fluid tubing requirements are shown
in “Fluid Tubing Connection Requirements”
below
