DSA3200-PTP Sensor Replacement

The piezoelectric pressure sensors in the DSA-PTP module
are field replaceable. If a sensor needs to be replaced,
contact Scanivalve Technical Support before attempting to
change a sensor. New sensors can be obtained from Sca-
nivalve or any official Scanivalve Representative. Extreme
caution should be taken when changing a sensor.
CAUTION! ESD protection is required
for this procedure. Failing to follow
ESD protection guidelines could cause
permanent damage to the DSA-PTP
electronics.
The procedure shows a DSA3217-PTP module, but the pro-
cedure is very similar for a DSA3218-PTP. Simply remove
the top and side of the DSA3218-PTP enclosure, remove
the "core" assembly and pick up the procedure at step 4.
The following equipment is required:
ESD protection
#1 phillips screw driver
#2 phillips screw driver
5/64" allen wrench
3/32" allen wrench
Step 1: Remove the bottom mounting plate
Using a #2 phillips screwdriver, remove the 4 screws that
attach the bottom mounting plate.
Figure 6.11: Remove bottom mounting plate
Step 2: Remove the top plate
Using a 3/32" allen wrench, remove the 8 allen screws
holding the top plate on. These are "captive" screws so
they do not have to be completely removed.
Figure 6.12: Remove top plate
Step 3: Remove the case half screws
Using a #2 phillips screwdriver, remove the two remain-
ing screws that are securing the two case halves
together.

Step 4: Separate the case halves
Gently separate the two case halves from each other.
Make sure to pull squarely to prevent damage to the
A/D board interface connector.
