connected in between the ground terminal
of the mounting bracket and the ground
reference of the process.
Alternate way to prevent ground loop is
to isolate the SA11 & mounting plate from
ground 2 & keep the terminal 82 connected.
Remark: For the installation shown in Figure
5.5, in case the ground references at the
HOST side (Ground 1) and process side
(Ground 2) have no potential difference the
shield wire of the WU11 type -S cable (wire
#82) can stay connected to the (pre-defined)
ground terminal at the HOST.
In combination with Host who does not have
grouding terminal to still meet the statutory
regulations it is necessary to ground either
the SA11 enclosure (e.g. by using the option
/UM) or ground the shield of the cable. An
example is shown in figure 5.6.
Operation
Select a YOKOGAWA parameter specific sensor equipped with an ID-chip which is suitable
for the process. When all wiring is completed, turn on the power of the HOST system. Part
of the setup of the SA11 will be done automatically by reading the content of the ID-chip of
the sensor. These are sensor characteristics, factory calibration data, customer calibration
data, diagnostics and loggings of calibration and events. For details refer to the SA11 Smart
Adapter User’s Manual. Other setups have to be done by the YOKOGAWA HOST system,
for details see the belonging User’s Manual. If the system is configured incorrectly, an error
indicator may be displayed, or the measurement values displayed may be incorrect. Refer to
the User Manual of the HOST system how to check the initial settings and change them to
suit your purpose.
