PRODUCT DESCRIPTION
The BG-SW is an electronic bilge pump switch that uses patent-pending technology to precisely and reliably pump water out of the bilge. Pump power is
controlled by the BG-SW.
The BG-SW can be tested and its status can be viewed using the BGI Config App, which can be downloaded from the App Store or Google Play. The App is
used on a mobile device with Bluetooth to wirelessly connect to the BG-SW device. The App will report the input voltage level and system temperature. It
also allows changing the name of the device for easy identification and testing the device.
INSTALLATION
The BG-SW is designed for mounting near the bilge pump in a vessel.
It should be mounted approximately 2” above the bilge pump outlet as
shown in the Blue Guard Installation Guide. A mounting bracket and three
#8x0.75” 316 stainless steel screws are provided to allow mounting to a
vertical or horizontal structure.
If the device is mounted on the bottom of the hull of the vessel the strain-
er should be mounted first and then the main unit attached.
The Blue Guard Installation Guide shows the wiring for all supported con-
figurations. All wiring connections are made using heavy-duty 14 gauge
marine grade wire. All wiring should be done by a licensed electrician
following NEC code.
INSTALL STEPS:
1) Locate proper mounting location for the BG-SW, near the bilge pump
and approximately 2” above the pump outlet.
2) Install mounting bracket to bulkhead using two #8x0.75” 316 stainless
steel screws provided*.
3) Attach the BG-SW into bracket with product label facing up, and wiring
close to bracket.
4) Run wiring to BG-JBox, BG-CP, bilge pump, and battery depending on
the installation chosen from the Blue Guard Installation Guide. Secure
the wiring. It is recommended that connections to the BG-JBox be
made using 14 AWG crimp spade lugs at the ends of the wires.
5) Apply power to the system.
6) Connect to the BG-SW using the BGI Config App to view the status of
the unit and test, and set the unit name. The App can be used to view
the system parameters at any time.
*Note that the BG-SW can also be mounted on the hull using three #8x0.75” 316 stainless steel
screws. Mount the strainer first, then attach the BG-SW into place.
PUMP RUN TIME
Set the pump run time after water detection via the BGI Config App.
Set BG-SW Switch Pump Run Time*
After Water Detection Event (Normal) — Set pump run time
(15-60 seconds). Factory default is 15 seconds.
*After water is detected, the pump will be activated. The pump timer set above will start when the
sensor detects air during pump activation.
