3.1.2.2
Affects on Diagnostic Systems
Be aware of the additional phase, gap, and vibration errors that will be present
(refer to the Specification sheet at the end of this manual). The following
measurements are affected by the additional voltage errors:
•
Shaft centerline plots are affected by the dc offset.
•
Gap measurements are affected by the dc offset.
•
The additional phase error could affect orbit plots. The amount of error
depends on the frequency of the vibration.
•
The additional ac error will affect vibration measurements.
3.2
Installing Backplane Hardware
These procedures show how to attach Vibration Transducer Interface modules,
connectors and the earth rail to the backplane. Before you begin, take note of
the following precaution about installing components in hazardous areas:
WARNING
Do NOT install a backplane or
other safe area components in a
hazardous environment. An
explosion may occur if safe
area components are installed
in a hazardous environment.
Install the 3500 Galvanic Isolator Interface in a safe environment unless the
modules are protected by a locally acceptable explosion proof technique.
