Dispensing Valve Pneumatics
Perform the following procedure to check function of the Dispensing Valve pneumatic system.
? NOTE This procedure assumes that you are already in the FmNT Dispenser I/O Test dialog box.
If not, refer to the first two steps in the Needle Sensor test procedure.
1. If a Dispensing Valve is currently installed on your dispensing system, disconnect all air
hoses connected to the Dispensing Valve.
2. Connect a syringe receiver head to the silver-colored Fluid Pressure fitting on the Valve 1
pneumatic Bulkhead located on the left-hand side of the Dispensing Head.
3. On the PIO 96 Channels 0-1 tab, locate the bit labeled
V1_FLUID.
4. Toggle the bit until it reads
1.
> This should turn ON air at the Valve 1 Fluid Pressure port. You should hear air coming
out of the syringe receiver head.
5. With Valve 1 fluid air ON, adjust the Valve 1 Fluid Air Regulator so that pressure increases
and decreases.
> The Air pressure coming from the syringe receiver head should vary with Regulator
adjustment.
6. Toggle the
V1_FLUID bit until it reads 0.
> This should turn OFF air at the Valve 1 Fluid Pressure port.
7. Disconnect the syringe receiver head from the Valve 1 Fluid Pressure port and connect it to
the blue fitting on the Valve 1 pneumatic Bulkhead. Also connect a syringe receiver head to
the black fitting on the Bulkhead.
> Air should be coming out of the syringe receiver head connected to the black fitting. No
air should be coming out of the syringe receiver connected to the blue fitting.
8. On the PIO 96 Channels 0-1 tab, locate the bit labeled
V1_VALVE and toggle the bit until it
reads
1.
> This should turn OFF the air coming out of the syringe receiver head on the black fitting
and turn ON the air coming out of the syringe receiver head that you connected to the
blue fitting.
9. With Valve 1 air ON, adjust the Valve Air Regulator so that pressure increases and decreases.
> The air pressure coming from the syringe receiver head should vary with
Regulator adjustment.
10. Toggle the
V1_VALVE bit again until it reads 0.
> This should turn OFF the air coming from the blue fitting and turn ON the air coming
from the black fitting on the Bulkhead.
