Pulse Totalizer Input Module
The Model 3515 Pulse Totalizer Input
(PTI) Module provides 32 individual
31-bit counters that operate indepen
dently. The counters are used with
active-flow sensors or per-unit sensors
to measure a quantity (count) which is
transmitted to the Main Processors. At
the time specified by the control
program, the Main Processors clear a
single counter or all counters.
The PTI module has three isolated input
channels. Each input channel indepen
dently processes all input data and
passes it to the Main Processors, where
it is voted before processing to ensure
the highest integrity.
Each PTI module provides complete
ongoing diagnostics on each channel,
including channel-to-channel count
comparison. Failure of any diagnostic
on any channel activates the Fault indi
cator, which in turn activates the
chassis alarm. The Fault indicator
points to a channel fault, not a module
failure. The PTI module is guaranteed
to operate properly in the presence of a
single fault, and may continue to
operate with certain kinds of multiple
faults.
The PTI module can operate with or
without a hot-spare module. If you use
a hot-spare module, it re-educates all
counter values from the active module.
