Initial check and setup identification
Keep the area between the negative charging lug (A) and the
water detector (B) clean to reduce the risk of activating the
sensor. If necessary, apply silicon grease to disrupt conductive
paths.
1 Using a multimeter, check the voltage between the
negative charging lug (A) and the water detector (B).
Make sure the sensor is charged:
- Fully discharged: Voltage less than 11.5 Vdc
- Fully charged: Voltage greater than 13.5 Vdc
- Approximately 50% capacity left: 12.8 Vdc
2 With a small piece of wire, complete the circuit between
the sensor’s sea water detector (B) and negative charging
lug (A).
- The sensor will respond by flashing its individual LED
identification codes.
(1) = One long flash: It has a duration of
approximately 1 second.
(2) = One start flash: This signals that the first digit of
the channel number is next.
(3) = None, one, two or three short flashes: The
number of short flashes signifies the first digit of the
configured channel number.
