Bottom Contact test procedure

Tools and equipment required

• Multimeter

• A small piece of wire

• PI Service Hydrophone (Order no. 314-204480)

• PI System

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.
