Transducer Selection
The primary transducer (address 0) is selected by
default at power up. The Local Operation and
Remote Operation sections of the manual show
how to select either transducer as the active
transducer through the LIMITS/SETUP menu in
manual operation, or with the _PCS4 XDUCER
command over a remote bus.
In addition to menu or bus selection, the F1 key
([2nd] [0]) is configured to toggle between the pri-
mary and the alternate internal transducers.
When commanding a transducer change, if the
current pressure is more than 10% (or 1 psi,
whichever is greater) over the maximum or under
the minimum range of the selected transducer the
change will not be accepted, and the display will
show the following message:
WARNING 01: UNABLE TO CHANGE TRANSDUCER
CURRENT READING OUT OF RANGE (USE CE)
Pneumatic Module
The pneumatic plumbing is arranged as shown on
the pneumatic schematic in figure 9.6. This module
includes a three-way solenoid valve (L6) installed
such that the MEASURE/CONTROL port is routed
to the primary transducer when the solenoid is
relaxed, or to the alternate transducer when it is
energized.
