Turning off the FX80
You must NEVER turn off the FX80 by means of the on/off switch on the Processor Unit. You must always close the FX80 program by selecting Exit on the top bar.
Context
When you do not use the FX80, turn off the display and the Processor Unit. It is important that you disconnect the high voltage power to the Communication Hub. To disconnect the high voltage power, switch off the Bridge Control Unit.
Caution
Do not connect or disconnect any cables while the system is turned on. Do not leave power on to ports that aren’t connected to anything (even if there are dummy plugs installed).
Procedure
1 If applicable, power off the DFS75 Trawl sonar.
a In the DATSS software, click the System button to see the available choices.
b Select Stop to stop the operation.
Neither transmission nor reception takes place, and there is no communication between the Processor Unit and the Sonar Head.
c Select Off to close the program.
2 In the FX80 software, click the Aux 1 button to disable Auxiliary Port 1.
Note
Aux 1 is the default label for this button. If you create a custom button label (SetupSystem SetupAux 1Button Label), then this button will have a different name.
3 Select Exit on the top bar.
Observe that the FX80 program closes down.
4 Press HV Stop on the Bridge Control Unit.
This removes the high voltage power to the Communication Hub in the Trawl Unit.
5 Power off the Bridge Control Unit.
There are two power switches on the Bridge Control Unit, one on the front panel and one on the rear panel. During normal operation, you only need to use the front mounted switch to power on (and off) the unit.
6 If the Processor Unit does not turn itself off automatically, use the functionality provided by the operating system to turn it off manually.
7 Turn off the display.
If required, refer to the instructions provided by the display manufacturer.
8 Retrieve the trawl.
9 Disconnect the cables between the units, and remove each unit from the gear.
