Operation (contd.)
Filling the System with IPA
1. Turn the FLUID MODE valve (1) to FILL.
2. Remove the caps from the flux and the isopropyl
alcohol (IPA) reservoirs (6, 8). Fill the reservoirs
and install the caps.
3. Turn the FLUID SELECT valve (4) to IPA.
4. Adjust the FLUID PRESSURE ADJUST
regulator (3) until the FLUID PRESSURE
display (5) reads 5 psi.
5. Turn the FLUID MODE valve (1) to RUN.
6. Set the DG-1000 AIR PRESSURE regulator (2) to
65–85 psi.
NOTE: Use the purge program or manually actuate
the DG-1000 dispenser.
7. Actuate the dump valve on the DG-1000
dispenser. Purge material for 3–4 sec. Turn off
the dump valve.
8. Manually actuate the DG-1000 dispenser solenoid
valve until solvent flows out of the DG-1000
dispenser.
Filling the System with Flux
NOTE: Place an empty container under the DG-1000
dispenser to prevent material from splashing.
1. Make sure that these parameters are set:
DG-1000 pressure: 65 psi
fluid pressure: 5 psi
fluid mode: RUN
fluid select: IPA
2. Open the 3-way purge valve on the DG-1000
dispenser.
3. Purge the DG-1000 dispenser until IPA appears.
4. Close the 3-way valve on the DG-1000 dispenser.
5. To remove the solvent from the fluid lines, adjust
the FLUID PRESSURE ADJUST regulator (3) until
13 psi appears on the FLUID PRESSURE
display (5).
6. Open the DG-1000 dispenser dump valve for
15 sec. Close the dump valve.
7. Adjust the FLUID PRESSURE ADJUST
regulator (3) until 5 psi appears on the FLUID
PRESSURE display (5).
8. Turn the FLUID SELECT valve (4) to FLUX.
9. Open the DG-1000 dispenser dump valve. When
flux appears, close the dump valve.
10. Actuate the DG-1000 dispenser for 10 sec or until
flux appears.
11. Adjust the fluid pressure to the normal operating
set point.
12. Run the TEST program.
