Mount the Device
The SeaHawk 10K can be mounted inside a panel or on a DIN rail. The device has two
adjustable orange clips on the bottom. Push the clips out to expose two screw holes that
allow the device to be mounted in a panel; push the clips in to mount the device on a DIN
rail.

DIP Switches
The SeaHawk 10K has two sets of DIP switches. Push the
numbered switch up to turn it on; push the switch down to
turn it off. SW1 is used to congure a variety of settings on
the Seahawk 10K. SW2 is used to congure communications.
DIP Switch 1, switches 1 through 8
Set the baud rate for the EIA-485 Port
1 = Off 2 = Off Modbus 9600 baud
1 = On 2 = Off Modbus 1200 baud
1 = Off 2 = On Modbus 38400 baud
1 = On 2 = On N2 9600 Baud
Unused
3 = Off Unused, leave in the off position.
Set the Re-alarm Interval - After a leak or cable problem has been detected, the alarm will be re-sent at a
designated interval until the alarm condition has been resolved.
4 = Off Re-alarm interval - disabled. No re-alarm will occur.
4 = On Re-alarm interval - 4 hours
Latching Alarm Status
5 = Off Unlatched alarms - alarm resets itself once a detected leak or cable problem has
been resolved
5 = On Latched alarms - alarm must be reset by manually pushing the blue Test/Rest/
Alarm Silence button, even if the leak or cable problem is no longer present
Distance Measurements
6 = Off Cable length displayed in feet
6 = On Cable length displayed in meters
Sensing Cable Resistance - If you have questions regarding your cable’s resistance, please reference the cable’s
data sheet.
7 = Off 2.8 Ohms per foot - Use with RLE’s orange sensing cable
7 = On 4.0 Ohms per foot - Use with most other sensing cables
Enable or Disable the Audible Alarm - The audible alarm is disabled by default.
8 = Off Audible alarm off
8 = On Audible alarm on
Establish Physical Connections & Test the Device
The SeaHawk 10K’s circuit boards are labeled. This helps you determine which wires feed
into each terminal block. Before you apply power to the SeaHawk 10K, wire all necessary
connections and set the DIP Switches.
1. Connect the power lead to TB3 or TB4.
2. Insert the four stripped wires of the leader cable into the appropriate slots in TB2 from left to right: white, black, green, and red.
3. Connect sensing cable to the other end of the leader cable, and be sure an end-ofline terminator is connected to the end of the sensing cable.
4. Secure your connection for the relay output to TB1.
5. Adjust the DIP switches to the appropriate settings.
6. Apply power to the SeaHawk 10K.
7. Test the system - simulate leaks at the beginning, middle, and end of the sensing
cable to ensure the SeaHawk 10K accurately calculates the distance to leaks.
DIP Switch 2 is used to set communications options. If you are communicating via
Modbus, use SW2 to set the address of the Modbus device. This should be a number
between 1 and 254. Adjust the individual switches until their sum equals the Modbus
address. Switch values are as follows:
Front Panel Indicators
The front panel of the SeaHawk 10K contains a 4-character LED and series of colored
LEDs that are used together to convey device status and information regarding detected
leaks and cable faults. A blue button is used to cycle the 4-character LED, silence the
audible alarm, and reset the alarm.

System is running in its normal operating state.
A leak, fault, or contamination has been detected. A numerical distance displays on
the LED. A green LED lights next to Ft or m, and either the LED next to the water
drop glows red to indicate a leak, or the LED next to the wrench glows yellow to
indicate cable contamination. If the distance is measured in meters, a tenths place
decimal value will appear in measurements from 0.0 - 999.9. All meter values over
1000 will display as whole meter measurements.
Cable break/fault detected. Yellow LED ashes next to wrench symbol.
Yellow LED - Cable fault - 4-characted LED displays cbr
Yellow LED - Cable contamination - 4-character LED displays distance
Green LED - Power on
Green LED - Measurements are made in feet
Green LED - Measurements are made in meters
Green LED - Microamps of current on cable - amperage displayed on 4-character LED
In normal operating conditions, the button functions include:
• Press once: Displays cable current in ohms/foot and the green LED lights next to
the microamp symbol
• Press twice: Displays the length of installed cable components and the green
LED lights next to the appropriate Ft or m symbol
• Press three times: Return to the default display (SH10 )
• Press and hold: Self-test is initiated and the character display reads cal 8060,
which indicates the value of the test resistor.
If an alarm sounds, briey press the button to turn off the audible alarm. The Status
LED remains red, and the 4-character LED continues to show the alarm condition.
In an alarm condition, whether the audible alarm is sounding or not, press and hold
this button for 3 seconds to clear the alarm.
Modbus Registers
The SeaHawk 10K uses its EIA-485 port to communicate via Modbus. The SeaHawk 10K
is congured to act as a slave device on a common network and is a slave only device – it
will never initiate a communications sequence.
