Should a message and the
"Air lock" symbol appear, this may mean
that there is gas in the liquid end (if
‘Warning’
or
‘Error’
was set in the
‘Air
lock’
sub-menu).
11.2.4.5 Compensation
Using the
‘Compensation’
programmable function, you can minimise the
influence of back pressure oscillations and thus achieve a high dosing pre‐
cision.
With difficult hydraulic conditions, it can be better to switch
off the ‘Compensation’ function.
