For Module Personality "Real Time - 2 Dynamic (4 kHz) - Dual Path":
Dual path uses both channel pairs to process one pair of transducer signals
without requiring external linking of the signal inputs. The sensors are
connected normally to channels 0 and 1 but are processed by both channel
pairs (channel 0 to channel 2, and channel 1 to channel 3). Consequently only
channels 0 and 1 are used for transducer status.
'Wire off ' refers to additional failure sensing applied to Eddy Current Probe
systems that are powered by the module. Wire off is only incorporated into
Transducer Fail when specific configuration criteria are met. If those criteria are
not met and/or the capability has been disabled by setting attribute 32 to a
nonzero value, then bit 3 is forced OK (zero value). If the wire off detection
capability is being actively used, then if a transducer fail is indicated, the value
of bit 3 confirms if a wire off has been detected. There is the possibility of
multiple checks (simultaneously) triggering an indication of transducer failure.
