VIOLATION MODES

The Violation Modes that the DataTrans Plus can enter, depending on the
situation, are termed Conditional, Delayed, and Immediate. Gauge Mode and
Permanent Violation Mode are continuations of these Violation Modes. It is
important to understand each different Violation Mode and how to carry out
emergency procedures in the event you enter one.

CONDITIONAL VIOLATION MODE

management abilities by entering the Conditional Violation Mode. If properly

A momentary rise above the ceiling, such as with a surge or swell, could cause
this to happen. Therefore you should stay slightly deeper than the exact ceil-
