Section 6: Advanced Diagnostics Configuration

Advanced Diagnostics Configuration
6.5.1 Turning ground/wiring fault on/off
The ground/wiring fault detection diagnostic can be turned on or off as required by the
application. If the advanced diagnostics suite 1 (DA1 Option) was ordered, then the
ground/wiring fault detection diagnostic will be turned on. If DA1 was not ordered or licensed,
this diagnostic is not available.
6.5.2 Ground/wiring fault parameters
The ground/wiring fault detection diagnostic has one read-only parameter. It does not have any
configurable parameters.
Line noise
The line noise parameter shows the amplitude of the line noise. This is a read-only value. This
number is a measure of the signal strength at 50/60 Hz. If the line noise value exceeds 5 mV, then
the ground/wiring fault diagnostic alert will activate.
6.6 High process noise detection
The high process noise diagnostic detects if there is a process condition causing an unstable or
noisy reading that is not an actual flow variation. A common cause of high process noise is slurry
flow, like pulp stock or mining slurries. Other conditions that cause this diagnostic to activate
are high levels of chemical reaction or entrained gas in the liquid. If unusual noise or flow
variation is seen, this diagnostic will activate and deliver an alert. If this situation exists and is left
without remedy, it will add additional uncertainty and noise to the flow reading.
6.6.1 Turning high process noise on/off
The high process noise diagnostic can be turned on or off as required by the application. If the
advanced diagnostics suite 1 (DA1 Option) was ordered, then the high process noise diagnostic
will be turned on. If DA1 was not ordered or licensed, this diagnostic is not available.
