Active Corrosion Protection
ACP (Active Corrosion Protection) is a system devel-
oped to provide optimum IPS unit corrosion protection
in salt water and brackish water.
ACP has three levels of protection that can be moni-
tored by the boat's electrical system. Presentation of
protection status on boat displays can be selected in
My view .
When the system is active a small amount of chlorine
gas is given off. If the smell is disturbing the ACP func-
tion can be temporarily switched of as desired in the
settings menu; refer to
Protection mode settings . The
system may be switched off for a maximum of 4 hours
during which time the IPS unit is protected against cor-
rosion by means of the secondary system; refer to
Protection levels .
The ACP reverts automatically to normal mode after 4
hours; should you wish to leave chlorine-free mode
earlier do so via the settings menu or by switching on
the ignition.
When berthed the boat should be connected to shore
power where provided. If shore power is lacking the
ACP uses the boat's batteries. If the batteries begin to
run down, disconnect the ACP and switch to the sec-
ondary system.
NOTICE! To avoid false alarms from the system when
running in freshwater environments where corrosion is
not so aggressive the function should be rendered
inactive. The IPS unit is protected by the secondary
system even when ACP is inactive.
Set the ACP to Normal mode if the boat is move to a
more aggressive environment.
