CAUTION
The Trident controller can be repaired while operating. However, the integrity of
the controller can only be assured if the operator follows maintenance procedures
correctly. If the operator is in doubt about the procedures, he or she should take
whatever steps are necessary to ensure the safety of the plant and personnel, then
call Triconex for assistance in implementing the maintenance procedures.
