Model WU11
Interconnection/Extension Cable
for SENCOM® Products
1 GENERAL
1.1 INTRODUCTION
The WU11 interconnection and extension cable is
specified for reliable transfer of digital signals between
the SENCOM products and SA11 module and
Yokogawa FLXA analyzer. (Suffix -V is for FU20F,
FU24F, SC25F and IB100 / Suffix -S is for SENCOM
SA11, BA11 and IB100). It is especially designed to be
installed in a heavy industrial environment. The double
shielded cable will protect the connected devices for
interference from high voltages and currents which are
present on other cables. The cable is specified to be
used in IP67 applications, allowing it to be submerged
as a whole. The cable has a wide temperature
operation range which is sufficient for most of the
applications. The materials used for the cable are flame
retardant to resist the spread of fire.
Depending on cable layout there is a choice of 8
different length to suit the customers needs.
1.2 Unpacking & Checking
Upon delivery, unpack the cable carefully and inspect
it to ensure that it is not damaged during shipment. If
damage is found, retain the original packing materials
and immediately notify the carrier and the relevant local
Yokogawa Sales office. Make sure the Model Code
and Serial Number on the cable are the same as on
the packing list.
1.3 Warranty & Service
Yokogawa products are guaranteed free from defects
in workmanship and materials under normal use and
service for a period of (typically) 12 months from the
date of shipment from the manufacturer. Individual
sales organizations can deviate from the typical
warranty period, and the conditions of sale relating
to the original purchase order should be consulted.
Damage caused by wear and tear, inadequate
maintenance, corrosion, or by the effects of chemical
processes are excluded from this warranty coverage.
In the event of a warranty claim, the defective goods
should be sent (freight paid) to the Service Department
of the relevant Yokogawa Sales office for repair or
replacement (at Yokogawa’s discretion).
The following information must be included in the letter
accompanying the returned goods:
• Model Code and Serial Number.
• Original Purchase Order and Date.
• Length of time in service and description of the
process.
• Description of the fault and circumstances of the failure.
• Process/environmental conditions that may be related
to the failure of the cable.
• Statement as to whether warranty or non-warranty
service is requested.
• Complete shipping and billing instructions for return of
material, plus the name and phone number of a contact
person that can be reached for further information.
• Clean Statement
Returned goods that have been in contact with
process fluids must be decontaminated and
disinfected prior to shipment. Goods should carry a
certificate to this effect, for the health and safety of
our employees. Material Safety Data sheets must be
included for all components of the process to which the
cable is been exposed.

2.8 Cable installation
Procuring a smooth bend radius allows the
cable to absorb the impact of bending and
thereby increasing its life cycle.
Minimum bend radius is approx. 5 cm (2”).
When using cable ties, do not pinch or deform
the cable.
When connected cable is subjected to any
motion between two points, stress on the cable
can be prevented by an adequate cable length
or using a cable loop.
