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