Operational Notes
PowerGuard
PRO
is a remote battery switching and flat battery protection system. This allows you to
mount battery master switches in convenient locations such as dashboards or helm panels without
needing to run heavy duty cables throughout the vehicle/boat.
PowerGuard
PRO
combines battery protection and remote switching. By monitoring the battery
voltage PowerGuard
PRO
can disconnect the battery (or batteries) from the loads to prevent excessive
and damaging discharge.
The Isolator switches provide a manual ‘override’ function to reconnect the battery (or batteries).
Remote Battery Switching
The Battery Isolator switches control connection or disconnection of the battery (or batteries).
PowerGuard
PRO
can switch up to 2 independent battery banks.
Flat Battery Protection
PowerGuard
PRO
can prevent a flat battery condition by disconnecting the battery (or batteries) from
the load. It achieves this by monitoring the battery voltage levels. If the voltage level falls below the
threshold for longer that the pre-set time, then the system is disconnected.
EMERGENCY OVERRIDE
: Pressing the ‘override’ switch will re
-connect the battery power.
The connect/disconnect voltage threshold level(s) and the pre-set time delay are set using the
trimming potentiometer (“trim
-
pots”).
In systems with 2 batteries (or 2 battery banks) the second battery is separately monitored and has a
separate contactor and Isolator switch to provide an ‘override’ function.
