9.0 Common Questions & Answers
Q. I have connected the ISA500 to the Topside Interface Box but cannot establish
communications with the unit.
A.
In order for the ISA500 Probe to operate with the Topside Interface Box, the probe must be
set to RS485 communications.
If the unit is set to RS232, the communications can be changed back to RS485 using the ISA500
Application.
Q. In the seaView software there are many applications (ISA500, ISD4000, FMD etc) - which
do I use for Flooded Member Detection?
A.
Only the 'FMD' application is required for Flooded Member Detection work. seaView has the
ability to support all Impact Subsea sensors and thus has an application to suit each.
The FMD application will configure the ISA500 acoustic settings (pulse length, min & max range
etc) to suit each member under test. There is no requirement to manually adjust the acoustic
settings of the ISA500.
Do not use the ISA500 application while the FMD application is open. The ISA500 application is
intended to use the ISA500 Probe as an Altimeter.
Q. When conducting the FMD test, does the ISA500 probe have to be touching the member
under test?
A.
In theory the ISA500 probe can be slightly away from the member under test,
however it is
recommended that the ISA500 probe is in direct physical contact with the member under test.
Q. When conducting the FMD test, do I need to remove marine growth from the member
prior to test?
A.
All marine growth must be removed prior to the ISA500 probe being coupled to the member
under test. The ISFMD system operates through the use of acoustics and thus requires a good
acoustic coupling to be made with the member under test.
