Installation
Initial Material Loading and Filling
WARNING
MOVING PARTS HAZARD
To reduce risk of injury or damage to
equipment, make sure all material hose
connections are secure.
WARNING
PRESSURIZED FLUID HAZARD
To reduce the risk of serious bodily injury,
such as fluid injection or splashing fluid in
the eyes or on the skin, always wear eye
protection and protective clothing when installing,
operating, or servicing this dispensing system
.
1.
Verify that supply lines to the meter are filled (see
Loading and Filling on pg 11).
NOTE:
Remove or open the dispense valve. Place the
valve or hose end over an appropriate material waste
container, and open the material inlet valve to the
meter. This will allow the system to fill without restric-
tion.
2.
Turn on Ultra–Flo unit per Start–up control instruc-
tions supplied by Robot Manufacturer.
NOTE:
During initial system fill, use a relatively low
speed, 20–30% of full speed.
3.
Turn on the air supply to the pumps and ram.
4.
Dispense and reload the meter until air–free mate-
rial is dispensed.
NOTE
: While dispensing, verify that the dispense valve
is open during a dispense cycle, and closed otherwise.
5.
Set the desired flow rate per Robot Manufacturer’s
Control Instructions.
CAUTION
The inlet pressure to the meter should never exceed
2500 psi.
NOTE:
Adjust the inlet valve stroke so that the cylinder
rod retracts at approximately 1/2” per second.
NOTE:
You will notice pressure faults (Robot Dispens-
ing Controls) and bleed interruptions until the meter is
full, and until the required flow rate is established.
Supply Pump Adjustment
Adjust the air pressure to each supply unit pump until
the desired flow rate/bead characteristics are
achieved, and the mastic regulator has been adjusted.
For the Ultra–Flo meter do not exceed 2500 psi materi-
al pressure on the meter. Pressures between 500 and
2000 psi are ideal.
WARNING
PRESSURE RELIEF PROCEDURE
To reduce the risk of serious bodily
injury, including fluid injection, splash-
ing in the eyes or on the skin, or injury
from moving parts, always follow this procedure
whenever you shut off the pump, such as before
checking and servicing system components.
1.
Engage the dispensing valve safety latch (if
applicable).
2.
Shut off air supply to the pump and ram.
3.
Open the drain valve and/or pump bleeder
valve. Have a container ready to catch the
material drainage.
4.
Release the dispensing valve latch and trigger
the dispensing valve to relieve any additional
pressure.
5.
Leave the drain valve open until you are ready
to dispense again.
If you suspect the dispenser nozzle or hose has
become completely clogged, or that pressure has
not been fully relieved after following the steps
above, VERY SLOWLY loosen the tip guard retain-
ing nut or hose end coupling and relieve the pres-
sure gradually, then loosen completely. Clear the
tip or hose at this point.
