If the message constantly repeats after several pumphead installations, then there may be
a leak detection sensor failure. Please contact Watson-Marlow for repair.
If you need to bypass a faulty leak detection sensor then you can do so by pressing
IGNORE
. If the power is cycled, the leak detection sensor will be switched back on.
If the leak detector is
IGNORED
then the leak detection off icon will be displayed on the
HOME
screens.
