CONFORMAL COATING
After installation and testing have been completed, the last step is to conformally coat the
summing card using Cardinal Part number 6560-0017, CONFORMAL COATING, SILICONE.
Apply the coating by spraying from top to bottom, holding the can 6 to 8 inches from the summing
card. It is best to apply 2 to 3 coats changing the angle a little each time for the best coverage.
The coating dries to the touch in 1 hour and cures in approximately 72 hours. The wiring should
not be disturbed until after the curing time.
MAINTENANCE
Like any other scale the Guardian system needs routine maintenance to keep it working to its
potential. Since there are no electronic components in the scale itself this is simplified on the
Guardian.
1. After initial installation it is recommended that gauge gaps on the load cells be checked
after the scale has been in use one week, again after one month of use and then every
six months. If there is a very small leak in one of the cell circuits it may not be apparent
during initial setup and calibration of the scale.
2. The scale should be inspected for dirt and debris under the weighbridge or vessel and
cleaned every three (3) months or more often depending on the application.
