NOTE:
See the
diagram.
2.
1. Perform the setup procedure for feed system com-
ponents. See your feed system manual(s).
2. Place an in-line air pressure regulator, air-water
separator/filter, and shut-off/bleed valve between
the air supply and the control solenoids.
3. Connect each of the supplied 1/4 in. outside diame-
ter air line to the corresponding control solenoid.

4. Connect the chemical lines from the feed system to
the metering valve material inlets. See
Typical Installation
Air Controller:
The Model 1093 requires a programma-
ble servo or stepper motor controller. Both options are
offered by Graco, but can also be supplied by the cus-
tomer. The inside diameter of the standard motor cou-
pler is .25”.
Air Lines:
Install the pneumatic supply lines for spool
shifting between the fill and dispense cycles.
•
Minimum air pressure required is 70 psi (4.8 bar).
•
Maximum air pressure is 100 psi (6.9 bar).
•
Pneumatic supply lines of .16 inch ID X .25 inch OD.
Spool Position Sensors:
The spool sensors are mag-
netic reed switches that must be connected to an electri-
cal control. An LED on the switch illuminates to indicate
the shifting of the spool.
Home Position Sensor:
The home sensor indicates the
position of the Metering Rod Connection Block (the typi-
cal “home” position).
Coupling and Lead Screw:
The coupling and lead
screw must rotate counter-clockwise to dispense and
clock-wise to fill. Verify proper rotation of the servo or
stepper motor.
