In redundant PIM modules, after a switchover, if the alarm for the reported channel still persists on the new primary, this most likely indicates a problem in the field wiring.

The following list summarizes the various components in the overall PIM connectivity block
diagram.
l The field device connects to the IOTA screw terminals labeled SIG IN(x) and COMMON(x) where
“x” denotes the channel numbers 1 through 8.
l The field sensor pulse output is conditioned by the input protection circuitry and filtered to
reduce unwanted high-frequency noise. The filtered output is fed to the high-speed
differential comparator which has a user-selectable threshold control. From Control Builder,
you can select an appropriate low or high voltage threshold based on the sensor type and the
value of the signal amplitude (Vs).
l Comparator hysteresis is also provided to further reduce false triggering especially for slow
rise/fall time signals.
l Each of the eight PIM input channels are electrically isolated from one another and from
system ground (cabinet ground).
l A comparator monitors the isolated +24 V channel power supply with respect to COMMON(x)
and can detect a problem in the field wiring. If the output of the isolated supply falls below 22V
or rises above 26V, a failure is indicated. Failures can be any of the following;
o A short in the field wiring.
o EXT BIAS(x) pin is shorted to COMMON(x).
o Excessive current is being pulled from EXT BIAS(x) pin.
o Power supply fails for some other reason.
If a failure occurs, the soft failure is reported in Control Builder and Station
.
