15.2.3 Max OK & Min OK (Fault Limits)
The setting specifies the fault values for the selected transducer. When the transducer signal is
outside the OK limits the channel is faulted (Not OK) and channel data is marked invalid.
When you select a transducer, these values are set to recommended values.
15.2.4 Transducer Power
Specifies the power to be provided to the sensor. When you select a transducer, this value is set to
the recommended setting.
If you are using the VC-8000 rack as a PI/CMS Gateway (see section 5), set the transducer power to
‘High-Z Input’. High-Z input is used when connecting to low-impedance sources (i.e. buffered output
signals from another monitoring system).
15.2.5 Transducer Fault Mode
Controls how sensor faults are handled. When you select a Channel Type, this value is set to the
“best practice” value automatically.
Latching Faults
Latches the fault condition until the user resets the rack.
This setting is rarely used.
Non-latching Faults
Channel state returns to valid immediately, when the sensor
returns to normal conditions.
Timed Fault Defeat and No Latching
Channel state returns to valid 20 seconds after the sensor
returns to normal conditions. This is the recommended setting
for Radial Vibration channels.
