Ransburg RMA Indirect A11600 - Manual (Page 54)

Atomizer Removal (See Figure13)
Remove rear split shroud by loosening the flat head
retaining screws and pulling the shroud halves
away from the atomizer extention. Loosen the high
voltage nut (78441-00) that holds the high voltage
cable into the curved high voltage tube. Remove
the high voltage nut and ferrules from the high
voltage cable. Loosen the quick disconnect ring
(A11201-00) with the adjustable spanner wrench
(76772-00) in a counter-clockwise direction. Pull
atomizer away from robot plate while taking care
to feed the high voltage cable back through the
atomizer.
Atomizer Reassembly
Rear shroud halves must be removed for atomizer
reassembly. Insert the high voltage cable through
the center hole of the atomizer and feed the ba-
nana jack end through the hole in the atomizer
extension. Once the cable is through, slide the
applicator towards the robot plate and align the two
guide pins with the holes in the robot plate. Push
the atomizer to the robot plate until both plates
are flush. Engage the mounting ring and tighten
securely. Remove the curved high voltage tube
from the high voltage ring. Slide the high voltage
nut and ferrules onto the high voltage cable, then
slide the curved tube over the high voltage cable.
Leave assembly loose. Insert the banana jack
end of the cable into the rear opening in the high
voltage ring until it seats firmly. Slide the curved
tube towards the high voltage ring and secure in
place by tightening the large locknut (A11318-00)
by hand. Insure high voltage cable is in place before
tightening high voltage nut and ferrule (78441-00)
by pushing high voltage cable towards the high
voltage ring. Tighten nut and ferrule securely
by hand. Reinstall rear shroud halves. Tighten
screws 3-5 lbs•in (.34-56 Nm) torque.
Proper high voltage cable installation may be veri-
fied by checking probe resistance from electrodes
to the end of the high voltage cable per the use of
a Yakogawa megohm meter or equivalent. Attach
one lead to the end of the high voltage cable and
touch the other end to the wire at the tip of each
electrode, one at a time. The reading should be
per "Chart A". If not, recheck connection in the
high voltage ring.
High Voltage Ring Removal/Re-
placement
Loosen the high voltage locknut (A11318-00)
and pull curved tube from back of high voltage
ring. Grasp the high voltage ring and turn count-
er-clockwise approximately 10-15° until locking
pins disengage. Pull ring forward to remove.
To reassemble, insure o-ring on inside diameter
of the high voltage ring and on face of atomizer
extension are seated properly in their grooves.
Lightly lubricate both o-rings with A11545-00 pet-
rolatum jell. Slide high voltage ring onto atomizer
body making sure high voltage input is located at
the top of the unit. Push firmly until it stops against
the atomizer extension and is engaged on the
locking pins. Rotate high voltage ring clockwise
>
Before installing high voltage ring,
fill the cavity in the high voltage ring with
dielectric grease between the input and
the outer diameter).
NOTE
10-15° to lock ring into place. Some force may
be required with a new ring, but a solid lock will
be felt when properly installed.
Before installing the curved tube, ensure the outer
ring of the high voltage input is filled with new
dielectric grease. Reinstall high voltage cable
and curved tube and tighten locknut securely by
hand. Proper high voltage cable installation can
be verified by checking probe resistance from the
electrodes to the end of the high voltage cable per
use of a Yakogawa megohm meter or equivalent.
Attach one lead to the end of the high voltage
cable and touch the other end to the wire at the
top of each electrode, one at a time. The reading
should be per "Chart A". If not, recheck connection
in the high voltage ring.
