7860C-RS Radial Spinner System
Installation Guide
Introduction
The 7860C-RS radial spinner system is a precision, air-actuated spinner device that produces a narrow radial output band ideal for coating the interior walls of cylindrical shaped parts. Air pressure is released to the colleted air motor to spin the radial disc and shaft assembly. During this radial spin cycle, fluid is dispensed onto the spinning disc, causing it to be distributed in a narrow band-like pattern onto the side wall.
The spinner disc and shaft assembly have a shaft length of 70mm (2.75"), with disc sizes ranging from 9mm (0.354"), 12mm (0.473"), 15mm(0.590"), and 19mm (0.745"). The radial spinner system is easy to use and will operate for many millions of cycles without maintenance.

Installation
Prior to installing this system, read the associated reservoir and ValveMate™ 7160RA controller operating manuals to become familiar with the operation of all components of the radial spinner system.
NOTE: Refer to the
ValveMate 7160RA controller operating manual for air connection instructions.
1. Mount the radial spinner bracket using
the rod provided or bolt it onto an appropriate mounting fixture. Follow these steps to install the radial spinner valve:
a. Slide the valve up into the bracket
opening until it bottoms out at the actuating air fitting. Secure in place.
b. Install the special bent tip in the
rotating luer lock adapter. Make sure the tip end is in the vertical position.
c. Slide the air motor into the bracket
opening. Make sure the motor collet does not make contact at the bend of the dispense tip.

d. Insert the shaft into the collet.
Set the tip approximately
0.5mm (0.20") from the spinning disc surface. Tip alignment should be 2.5 mm (0.100") away from the radial spinner shaft.
e. Realign the valve and motor
in the bracket as needed to achieve recommended clearances.
2. Connect the fluid feed hose to the
reservoir outlet and the valve inlet port using the appropriate fittings (supplied).

3. Connect the 4 mm diameter
air hose from the valve to the 7160RA controller. The white connector goes to the ACTUATING AIR port. Make sure the nozzle air is OFF and set to 0 bar (0 psi).
NOTE: The NOZZLE AIR port
is not used for radial spinner installations.
4. Connect the white and black
6mm diameter air hoses to the air motor assembly: white connects to the motor speed control and black connects to the F fitting (actual markings on air motor).

NOTE: Set the tip approximately 0.5mm (0.020")
from the spinning disc surface. Tip alignment should be 2.5mm (0.100") away from the radial spinner shaft.
5. Connect the white and black
6mm diameter hoses to the filter­regulator-lubricator assembly. White connects to the oil recovery bowl and black connects to the control valve.
6. Fill the fluid reservoir. After filling,
secure the cover and connect the reservoir air pressure regulator to

the air tee using the flexible air line (supplied). Attach the male quick-connect in the air line to the reservoir regulator and then attach the white quick-connect to the air tee. To pressurize the system, slide the shut-off valve in the air line toward the fluid reservoir.
7. Set the reservoir pressure regulator
according to fluid viscosity: low for thin fluids [0.07 to 0.2 bar (1 to 3 psi)] and higher for thicker fluids.
8. Set the 752V-UHSS valve (or other
appropriate valve model) stroke control to achieve a desired flow rate onto the spinning disc. Set the flow to approximately one drop per second.
9. Adjust the air motor RPM
using the speed control knob. Turn the speed control knob clockwise to reduce RPM and counterclockwise to increase RPM.
