9.5.1
Turning ground/wiring fault on/off
LOI menu path
Diagnostics > Diag Controls > Ground/Wiring
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.
9.5.2
Ground/wiring fault parameters
The ground/wiring fault detection diagnostic has one read-only parameter. It does not
have any configurable parameters.
Line noise
LOI menu path
Diagnostics > Variables > 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.
9.6
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.
9.6.1
Turning high process noise on/off
LOI menu path
Diagnostics > Diag Controls > Process Noise
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.
