The following are CBE Programming constraints:
•
There can be only one DEL or SDEL operator in a CBE equation, not
both.
•
If there is no duration time field in a DEL or SDEL, the equation is
always activated.
•
The maximum value of Delay Time + Duration Time is 255:59:59
(Hours:Minutes:Seconds).
•
If the day, or month, or year field is omitted, that field is assumed to be
all allowable values of the field omitted. Example: 12--90 is equivalent
to any day in December 1990.
•
The HH.MM field for Start Time and Stop Time uses military time.
•
The HH.MM field for Stop Time must be greater than the Start Time.
•
The maximum value of Start Time or Stop Time is 24:00.
•
If an alarm condition occurs, all active TIM devices are deactivated.
All TIM equations are ignored until all alarms are restored, at which
point all TIM devices return to their proper state.
