Composer Operating Manual
1.10.5.5 Transducer Series
Composer transducers are divided into two series. The controller must be
configured to match the transducer’s series by properly setting SW#1 CFGR1.
See
section 4.3.6.5 on page 4-25 .
The series is determined by the series designated on the transducer’s serial
number label. Set the switch active if the serial number’s series is 18 or lower,
otherwise leave the switch in the off state.
NOTE: The state of these switches is only read when power is first applied to
the controller. See Table 4-3 on page 4-25 for the configuration switch
number descriptions.
The series number is identified by referring to the serial number label placed on
the transducer, see
Figure 1-7 . In the SN field the transducer’s series is
identified as 19 (the 5th and 6th characters from the left) and would require that
SW#1 CFGR1 be left in the off position. Operation of a transducer with the
configuration switch in the wrong position may lead to improper operation at
very low pressures or false signals at vacuum.
