    Installation and Configuration If you are installing more than one SeaHawk 10K, use the appropriate pinouts of TB3 and TB4 to create a daisy-chained Modbus connection. A grounded shield contact is provided for connection to shielded cable. If the shield contact is used, verify the power connector is properly grounded and there is no voltage potential between units on the Modbus network.

    In a daisy chain. The SeaHawk 10K ships with the jumper in the non-terminated position - over the two pins closest to the device enclosure. If your SeaHawk 10K is the only device in the application, or if it’s not the last unit in the daisy chain, leave the jumper where it is.
  • Page 20: Set The Re-Alarm Interval

    2.5.2 Set the Re-Alarm Interval The SeaHawk 10K can be set to re-alarm – after a leak or cable fault has been detected, the alarm will be re-sent at a 4 hour interval until the alarm condition has been resolved. This re- alarm triggers both the audible alarm and the Modbus readout.

    3.1. Front Panel Controls and Display 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.

    4.1.1.5 5-1.2 Exception Responses If a Modbus master sends an invalid command to the SeaHawk 10K or attempts to read an invalid register, an exception response is generated. The response packet will have the high order bit of the function code set to one. The data field of the exception response contains the exception error code.

    4.4. Calibrate Cable Length via Modbus The length of sensing cable connected to the SeaHawk 10K can be calibrated through a Modbus-enabled system. This helps fine-tune a distance-read leak detection system. If no alarms are present, follow these steps to calibrate and test the system: Set the SW1 DIP switches for the correct cable resistance per foot, as follows: Figure 4.1 DIP Switch Settings for Ohms/Foot...
  • Page 36 This milliohms per foot value is your end result, and the number you will write to Modbus register 40008. Record this value. Access your Modbus-enabled system. Write the milliohms per foot resistance value to the SeaHawk 10K’s Modbus register 40008. Example: Leg2 Resistance (Modbus register 30007)
