shown below:
Figure 1-2
Diver setup
1.
Ensure all mains switches are OFF.
2.
Connect the topside unit to the mains supply using the RCD protected lead. If the local
supply is 230Vac then the included transformer will be required.
3. Connect the computer to the U41D topside unit, using the Ethernet cable. If the
computer needs to be powered from the mains supply, instead of running from the
internal battery, connect the mains lead to the 110V output connector on the topside
unit. For more advanced connection options, see Configuring the communications on
page 8.
4.
Connect the test and integration deck cable to the topside unit and connect the main
umbilical(s) to the other end of the test umbilical. Note that up to 3 main umbilicals may
be connected in series depending on requirements.
5.
Connect the main umbilical(s) to the subsea unit.
6.
Connect the probe(s) to be used to the U41 subsea unit. Ensure that any probe connector
which doesn’t have a probe connected to it is fitted with a blanking plug. Deploying the
bottle subsea with an exposed connector will cause severe damage to the unit.
7. Test the main cable RCD by turning ON the mains supply to the lead (with the topside
unit still switched OFF). Press the Reset button and verify that the red indicator is
showing. Press the Test button and confirm that the red indicator is removed. Press the
Reset button again and check that the red indicator reappears and remains. If this does
not function, or if during operation the RCD trips repeatedly, suspend all operations, turn
off mains supply and seek specialist advice.
8.
Check to insure the 110v indicator panel is illuminated.
9.
Turn on the power to the U41 system by pressing the power switch on the topside unit
panel.
10.
Test the safety trip on the topside unit. Press the Reset button and verify that the blue
indicator on the power switch is showing. Press the Test button and confirm that the blue
indicator is removed and the red fault light is displayed. Press the Reset button again and
check that the red fault light is extinguished and the blue power button light reappears
and remains. If this does not function, or if during operation the safety trip trips
repeatedly, suspend all operations, turn off mains supply and seek specialist advice.
11. The subsea bottle will take approximately 20 seconds to initialise following the safety trip
tests. Switch on the computer and start the ASSIST™ software.
