Ganz GXi Series VCA Interface Manual V3.05.31.18 Earliest Clause The 'earliest' clause is a special clause. It affects the start time reported by an 'and' clause. Ordinarily, the start time reported by an 'and' clause is the time at which the 'and' clause itself became true. With the 'earliest' clause, the start time reported is instead the earliest start time amongst the other input clauses. The 'earliest' clause can only be created as an input to an 'and' clause. In the example below the earliest clause will cause the reported start time to be at time one second past time zero, the start time of the event from zone 0. Without the 'earliest' clause the reported start time would be at time four seconds past time zero, the start time of the 'and' clause itself. 05-2018-A 56 | P a g e

Earliest Clause
The 'earliest' clause is a special clause. It affects the start time reported by an 'and' clause. Ordinarily, the
start time reported by an 'and' clause is the time at which the 'and' clause itself became true. With the
'earliest' clause, the start time reported is instead the earliest start time amongst the other input clauses.
The 'earliest' clause can only be created as an input to an 'and' clause.
In the example below the earliest clause will cause the reported start time to be at time one second past
time zero, the start time of the event from zone 0. Without the 'earliest' clause the reported start time
would be at time four seconds past time zero, the start time of the 'and' clause itself.
