IMPORTANT
The Dualtrack System uses one altimeter only. You must connect the altimeter to
the ALTIMETER port on the 440 SEP, or to an SDC serial port.
If you connect the altimeter to the ALTIMETER port of the 350 SEP the Dualtrack
System will not operate correctly.
3. Connect the 440 SEP to its PSU as described in this Manual.
Connect the Teledyne TSS 350 or 350 Powertrack sub-sea components:
4. Complete the physical installation of the coil triads as described in sub-section 3.2 of the 350 /
350 Powertrack Manual. Route the coil connection cables to the correct ports on the 350 / 350
Powertrack SEP. Use plastic cable clips to secure the cables to the ROV framework.
5. Connect the 350 / 350 Powertrack SEP to the ROV electrical supply by following the instruc-
tions in sub-section 4.1.3 of the Manual.
CAUTION
You might cause permanent damage to the sub-sea installations of the 440 or the
350 / 350 Powertrack System if you operate them from an incorrect electrical
supply.
The standard sub-sea components of both Systems operate from a nominal 110V
AC electrical supply. Optionally, both Systems are available for operation from a
nominal 240V AC electrical supply.
When you interconnect the 350 or 350 Powertrack and the 440 Systems within a
Dualtrack installation,
you must operate both Systems from the same electrical
supply .
6. Connect the communications conductors of the 350 / 350 Powertrack Power/Comms cable to
the ROV umbilical. Note that the Dualtrack System would normally use 2-wire current-loop
communications to the SDC to reduce the demand for twisted pairs in the umbilical. However,
where necessary, you may use 4-wire or RS232 communications instead. Refer to
Table 4-5 ,
Table 4-6 , or Table 4-7 in this Manual for appropriate connection details.
Connect the 440 System to the 350 System :
7. Use the 440-to-350 Link Cable (Teledyne TSS P/N B930477) to connect the 8-way ‘Power/
Comms’ connector on the 440 PSU to the AUX OUTPUT port on the 350 SEP. This link uses
RS232 communications at 9600 baud.
Note that the connectors at each end of the cable are of a different design. You cannot reverse the
cable when you make this connection.
Refer to section 4.1.2 "Care of Sub-sea Connectors" on page 4-3 in this Manual for instructions to care
for and assemble the sub-sea connectors. Make all interconnections between the sub-sea assemblies
and tighten the locking collars by hand. Do not over tighten the sub-sea connectors.
