Section 3. Installation Now, it’s time to connect the SNAP Vacuum Controller: The only required connections for operation are power, a vacuum pump, and a vacuum system. Hooking the SNAP up to a system is a simple process: 1.Mounting: Find a suitable location for mounting the SNAP. - Page 6 Operate the unit according to the directions in the next section just as you would with the internal sensor. © 2021 DigiVac Company®Allrights reserved. | 1020 Campus Drive, Morganville,NJ 07751 | (732) 765-0900...

Page 9: Controlling At A Setpoint
SNAP ships with PID variables that are optimized for average vacuum hose lengths for 20 and 50 liter vessels. The SNAP is capable of controlling much smaller and larger vessels, but may require some PID tuning to optimize the control. - Page 10 2.Select the recipe number to edit, then press EDIT RECIPE. 3.Customize the selected recipe by TIME (in minutes) and PRESSURE (in Torr)and whether you want to RAMP or HOLD © 2021 DigiVac Company®Allrights reserved. | 1020 Campus Drive, Morganville,NJ 07751 | (732) 765-0900...
- Page 11 RAMP: pressure will ascended for a duration of time expressed. Ex. You want to go from 60 Torr to 40 Torr in 2 minutes. SNAP will moderate pressure down to the new set- point so the pressure change is spread out linearly over the 2 minutes.

Page 12: Section 5. Troubleshooting
SNAP is performing as it should. If the last 2 tests are different, it means the SNAP is not performing optimally. Please consult your vendor for technical assistance. © 2021 DigiVac Company®Allrights reserved. | 1020 Campus Drive, Morganville,NJ 07751 | (732) 765-0900... - Page 13 This can be solved by resetting the PID. If SNAP is controlling too aggressively, try setting P=p/2.

Page 14: Section 6. Servicing And Maintenance
In many cases, a sensor may become fouled with oil or other foreign matter. It is often possible to restore the functionality of contaminated probes with cleaning. If the contaminant is known, the SNAP plumbing should be filled with a fluid that is known to be a solvent to that contaminant. Ethanol/alcohol are very powerful solvents and are highly effective against some contaminants. -
