With this confi guration, feedback is required on when parallel compression actually starts, using a digital
input on the main board. The position of the DI can be set on screen Cca12:
Parallel compression control board confi guration
It is recommended to manage activation and deactivation of parallel compression using the set point
variation from digital input function. The advantage of this compared to the ON/OFF from digital input
function is that the latter does not feature an alarm signal when the unit is OFF. This confi guration can be set
as shown in the following example:
1.
enable set point compensation for the parallel compression control board
2.
specify a compensation off set (e.g. 10 barg) for deactivation
3.
extend the set point confi guration range to allow application of the compensation off set
