TABLE FOR PRE-AND POST-IRRIGATION
In order to correct irregularities at the beginning or at the end of the irrigation strip the ECOSTAR has the
function pre- and post-irrigation. The precipitation height at the beginning of the strip (pre-irrigation) and at
the end of the strip(post-irrigation) is reached by short interruptions of the cart retraction. The downtime for
the pre-and post-irrigation is adjusted at the ECOSTAR with the program constant 2 and 3 on the parameter
sheet no.1. The program constant 8 was pre-set in the factory.
This factor links the retraction speed of the sprinkler with the pre- and post-irrigation time. The adjusted
factor can be changed, whereby pre- and post-irrigation changes.
The following table shows the pre-and post-irrigation times in minutes (rounded) at different adjustment
factors:
