Wait Segments

Wait prevents the program proceeding to the next segment, in a similar way to
holdback, until the selected 'Wait-For' parameter has been met. There are 5 'Wait For'
parameters. The first 4 only work if there are configured inputs to the controller.
1. PrgIn1 Wait until Input 1 is true
2. PrgIn2 Wait until Input 2 is true
3. PrgIn 1&2 Wait until Inputs 1 AND 2 are true
4. PrgIn 1or2 Wait until Inputs 1 OR 2 is true
5. PVWaitIP Wait until the measured temperature reaches a threshold value before
continuing. It can operate in one of 4 ways:
1. 'Abs Hi' Wait until the measured temperature is greater than or equal to a
value 'WaitVal' set for that segment.
2. 'Abs Lo' Wait until the measured temperature is less than or equal to a value
'WaitVal' set for that segment.
3. 'Dev Hi' Wait until the measured temperature exceeds a fixed* threshold by
an amount 'WaitVal' set for that segment.
4. 'Dev Lo' Wait until the measured temperature drops below a fixed* threshold
by an amount 'WaitVal' set for that segment.
* The fixed threshold used by deviation parameters is set in the configuration level of
the programmer and if required should be requested when purchasing a product from
Carbolite Gero.

Program Cycling

The 'Cycles' parameter sets the number of times the program will operate.
