Cable Assemblies
Connect Motor Control Cable
Motor control cables are supplied in four lengths, 6 ft
(1.8 m), 9 ft (2.7 m), 15 ft (4.6 m), and 55 ft (16.8). The
55 ft cable may be used by itself. The 6 ft, 9 ft, and 15 ft
cable must be used with the 55 ft cable.
To connect the motor cable between the control assem-
bly and the orbital dispenser, do the following:
1. Locate the receptacle on the bottom of the control
assembly labeled MOTOR CABLE on stand-alone
PrecisionSwirl control boxes or the receptacle
labeled SW-1 or SW-2 on PrecisionFlo XL control
boxes.
2. Connect the orbital dispenser cable (55 ft) to the
SW-1 or SW-2 (MOTOR CABLE) receptacle.
3. Check the connections to ensure the cable is con-
nected correctly.
4. Route the motor control cable and conform to the
following cable routing requirements:
• Avoid a bend radius of less than 5 in. (12.7 cm).
• Avoid pinch points.
• Avoid cable pulling or stretching.
• Keep cables from rubbing against other compo-
nents or machinery.
• If a lot of robot wrist motion is required, leave
sufficient cable length to allow for the motion,
avoiding any cable droops that may interfere
with the machinery or substrate.
• Route and secure the 7 in. motor cable to mini-
mize any movement. The 7 in. motor cable is
not intended to handle severe flexing motions.
• Cable ties should only be used to loosely bundle
hoses together. Do not tighten cable ties to the
point where cable movement is restricted.
The dispense valve must also be supported by
additional bracketing. The swivel union is not
intended to support the weight of the dispense
valve.
CAUTION

Operation
Pressure Relief Procedure
This procedure describes how to relieve pressure from
the orbital dispenser. See your supply unit or system
documentation for instructions on relieving pressure for
the entire system. Use this procedure whenever you
shut off the orbital dispenser and before checking or
adjusting any part of the system, to reduce the risk of
serious injury.
1. Shut off the material supply. Follow the Pressure
Relief Procedure in the material supply instruction
manual.
2. Make sure that all material valves are open.
3. Make sure the pump air supply has been turned
OFF.
4. Shut off the conditioning unit to the automatic dis-
pense valve. See the conditioning unit's documenta-
tion for more information.
5. Actuate the PrecisionSwirl dispense valve repeat-
edly until no fluid flows. Have a container ready to
catch the drainage from the orbital dispenser.
6. Relieve air pressure to the dispense valve.
7. If the orbital dispenser nozzle or dispense valve fluid
hose is completely clogged or if pressure has not
been fully relieved after following the steps above,
very slowly loosen the 3/4 in.-16 swivel union
between the dispense valve and the orbital dis-
penser, and relieve pressure gradually, then loosen
completely. Now clear the nozzle or hose.
MATERIAL FLUID HAZARD
To reduce risk of injury, wear eye protection, gloves,
and protective clothing when installing, operating, or
servicing this orbital dispenser.
SKIN INJECTION HAZARD
The system pressure must be manually relieved to
prevent the system from starting or spraying acciden-
tally. Fluid under high pressure can be injected
through the skin and cause serious injury. To reduce
the risk of an injury from injection, splashing fluid, or
moving parts, follow the Pressure Relief Procedure
whenever you:
• Are instructed to relieve the pressure
• Stop spraying/dispensing
• Install or clean the nozzle
• Check or service any of the system equipment
PRESSURIZED FLUID HAZARD
High pressures can cause serious personal injury. Be
sure to open the orbital dispenser during system
start-up to alleviate pressure which might occur in the
system due to material expansion.

Operation
10 309403J
Orbital Dispenser Operation
The PrecisionSwirl orbital dispenser is calibrated to run
from 6600-24,000 RPM maximum, in either automatic or
manual control mode.
The orbital dispenser, regardless of the nozzle size,
swirls material in a continuous path, over contours,
curves, and corners in a consistent bead when the con-
trol assembly and dispense valve are configured and
adjusted correctly.
The nozzle does not rotate, but its orifice moves in a
small circle at high speed to dispense a smooth, neat,
consistent bead of concentric loops without dimples, air
pockets, depressions, or protuberances. Bead shape is
affected by nozzle size, material composition, material
pressure, and the distance from the nozzle to the sub-
strate.
The orbital dispenser motor must be turned on at least
one second before applying a bead to ensure peak effi-
ciency.
Whether the PrecisionSwirl orbital dispenser is con-
trolled in either the Automatic or Manual mode, material
cannot be applied from the orbital dispenser unless the
dispense valve is actuated by some other interface to
enable material flow.
To extend bearing life, the orbital dispenser motor must
not run continuously. Shutting off the motor after each
dispense cycle reduces bearing wear and minimizes
temperature rise.
Turn off the PrecisionSwirl orbital dispenser when the
unit is not being used. The material inside the orbital
dispenser may cure if the motor runs continuously
when the orbital dispenser is not being used.
