Cool Drawer Single and Dual Sensors Operating Manual
4.1.2.3 System Diagnostics Pass But
Crystal Fail Message Remains
If the system is operating properly, yet the Crystal Fail message is still displayed,
perform the following tasks.
1
On the retainer verify that the center rivet is secure. Repair or replace the
retainer as necessary.
2
Inspect the inside of the drawer for a buildup of material. Clean or replace the
drawer as necessary.
After verifying the sensor head contacts, the sensor head/conduit tube connection,
and the retainer contacts, reassemble the system. If the Crystal Fail message
remains, replace the monitor crystal with a good monitor crystal. Verify that the
monitor crystal works properly by inserting it into a known good measurement
system. If problems continue, contact INFICON (refer to
).
