VSR (VOLTAGE SENSITIVE RELAY)
Located on the battery man-
agement panel are 2 VSR’s
(voltage sensitive relays).
Th
e purpose of the VSR is
to protect the engine batter-
ies from being discharged.
Also, when the engine bat-
teries are fully charged it
sends current to charge the
house battery.
When the cranking battery(ies) rise above 13.7 volts DC
the VSR switches to charge (cranking and house) both
batteries in parallel simultaneously. When the battery
voltage drops to 12.8 volts DC the VSR disengages.
Th
is VSR capability is referred to as “dual sense”. Th is
permits the VSR to sense the voltage of both batteries
that it is connected between. If one of the batteries is
receiving a charge the VSR will close by paralleling both
battery banks to charge the house battery along with the
2 engine cranking batteries.
Notice the illustration shows a LED light which indicates
when lite that the VSR is closed and is sending a charging
current to a battery(ies).
If the VCR senses the engine batteries are being dis-
charged at a fast rate it will open and will not allow those
batteries to be overly discharged to the point that the
engines will not crank over.
An example of the above situation would be if the vessel
was stationary at sea for an extended period with various
electronic and entertainment equipment energized along
with the engines and generator off the batteries would
normally discharge.
POSSIBLE PROBLEMS/SOLUTIONS (VSR)
1. Red LED light not visible at VSR- One
cause could be the remote battery switch
is not energized.
2. Red LED light stays on aft er the engine
is turned off - Th is is a normal condition. Th e residual
battery voltage because of battery charging has not yet
dropped below 12.8 volts for the VSR to cut out.
