2 Installation and Configuration
2.7. Apply Power to the SeaHawk 10K
An isolated power supply must be provided for the SeaHawk 10K. In addition, a
dedicated circuit breaker must be provided within close proximity to the
SeaHawk 10K and be clearly marked as the disconnecting device for the
SeaHawk 10K leak detection controller.
Do not connect 120/230 VAC to the unit, or damage will occur to the circuitry.
1
An isolated power supply was run and power was connected to the SeaHawk 10K in
Section 2.4.3 on page 17 .
2
Ensure all connections are correct and all screw terminals are secure.
Note
For AC power connections, wire EGND1 to Earth ground.
3
Apply power to the SeaHawk 10K. The device will begin to boot.
4
Wait approximately one minute for the SeaHawk 10K to start up. Under normal operating
conditions, the power LED glows green and the LED display reads
SH10
.
5
No alarm should be present. If an alarm is present, consult Chapter 6 for troubleshooting
information.
6
Press the Test/Reset button
once
to verify the amperage reading. For new leak detection
cable, the amperage will be either 0 or 1  A. If the current is higher than 0 or 1  A,
contamination may have been introduced during installation. Clean the floor, and then uses
isopropyl alcohol to clean the cable. If the sensing cable is not new, the reading may be
higher. RLE recommends cleaning the cable is the amperage reading is 15  A or higher.
7
Press the Test/Reset button
twice
to verify the length of installed sensing cable. If the length
displayed is different from the actual length installed, consult Chapter 6 for troubleshooting
information.
2.8. Test the System
Note
If the SeaHawk 10K is already connected to a BMS or NMS, notify monitoring personnel
before you begin testing the system.
1
To verify the SeaHawk 10K’s accuracy, test three points within the length of sensing cable
- one at the beginning, one in the middle of the length, and another near the end of the
length of cable.
2
There are a variety of ways to simulate a leak.

Pour a small puddle of water on the cable while it rests on the floor.

Dunk the cable in a cup of water.
