Reverse Battery Detection
If
Reverse Battery Detection
is enabled and a battery is connected with the incorrect polarity, the
SC200 will:
activate a
Wrong Battery Polarity
alarm, and
prevent any LVD from connecting.
Reverse Battery Detection uses the battery mid-point monitoring (MPM) analog inputs on an
IOBGP input/output board. Any of the mid-point monitoring analog inputs used for Reverse
Battery Detection are not available for MPM (see details on page
► To enable
Reverse Battery Detection
1
Before the batteries are connected to the dc power system, connect the mid-point
monitoring sense wires to the battery sides of the battery fuses/disconnect devices (leave
the fuses/disconnect devices open). Refer to the dc power system Installation and
Operation Guide.
There are four mid-point monitoring analog inputs on an IOBGP input/output board (for four
battery fuses/disconnect devices). Up to 20 additional battery fuses/disconnect devices can be
connected if additional IOBGP-01 input/output boards are connected. Refer to the dc power
system Installation and Operation Guide for details on how to connect additional IOBGP-01
input/output boards to the SC200.

In DCTools/Web go to
Analog Inputs
and for each mid-point monitoring analog inputs
used (one per battery fuses/disconnect devices) set the following parameters.

Wrong Battery Polarity Alarm
If
Reverse Battery Detection
is connected and enabled, the SC200 will activate a
Wrong Battery
Polarity
alarm if it detects that one or more of the batteries are connected with the wrong
polarity.
