.1 This Clause contains a
comprehensive range of field devices listed alphabetically by ``Point type'' code, not all
of
which
will necessarily be applicable to this project. Refer to the ``Point Type'' column on the
points lists in Section
15930
to identify the devices relevant to this project
.2 Some point types have a
number as the last character in order to identify variations in a group of similar field
devices.
For
each separate point type or group of similar devices (common point type except for number)
all items provided
shall
be the product of one manufacturer.
.3 All field devices shall
be selected to have full compatibility with the SAPs, TUCs or other controls components
being
proposed.
.4 Any field device
proposed for use which is not one of the products listed under ``Standard of Acceptance''
will be
evaluated
by the Owner's representative against the specified technical performance and the quality
and
characteristics
of the products which are listed. If any proposed field device is deemed not equivalent to
the
specification,
then the controls contractor shall provide another device which does meet specification at
no extra
cost.
.5 The shop drawing
submittal shall include technical data for all field devices listed in the points lists,
specifically
cross-referenced
to the particular point type to facilitate the shop drawing review.
.6 Some devices may
require different ranges, capacities, etc. in particular applications, even though the
device or
component
is otherwise the same. Where definition of such variations is required in the
specifications or points lists,
the
point type will use suffixes, for example ``DPS/x'' or ``DA1/x''. The suffixes are
explained in the ``Technical
Performance''
portion of each point type specification.
.7 The end-to-end accuracy
required for analog devices shall include the combined effect of sensitivity, hysteresis,
linearity
and repeatability between the measured variable and the output at the operator interface
device, or between
the
panel signal to the digital-to-analog converter and the controlled variable.
.8 Devices shall meet the
specific requirements listed, and shall be compatible with respect to power supply, signal
characteristics,
or other factors with the CCS being proposed. Power supplies shall be provided as required
for any
and
all devices.
