For access to configuration parameters, the setup switch must be pressed.
Prevents Service Access
Insert a lead wire seal through three fillister screws. This prevents access to the electronics, electrical contacts and Legal for
Trade configuration parameters.
Figure 2-9. Sealing the Indicator to Prevent Access
Only use the 1/4
"
screw in the top hole for sealing, using the longer one will damage the CPU board.
Allows Service Access – Optional
The calibration cover is used for inserting a lead wire seal through both fillister screws and the plastic cover. The cover allows
access to the electronics and electrical contacts, while preventing access into Legal for Trade configuration parameters.
There is an alternative cover over the A/D to ensure the A/D and load cell connection cannot be changed after the unit is
sealed.
There is also an audit trail counter to track calibration and configuration changes made to legally relevant parameters.
Place the calibration cover on the backplate and secure with the existing fillister head screws and o-rings to seal the indicator
for Legal for Trade approval.
