YVIB Installation
➢
➢
To install a new YVIB module into an existing control cabinet
1.
Securely mount the desired terminal board.
2.
Directly plug the YVIB I/O pack into the terminal board connectors.
3.
Mechanically secure the I/O packs using the threaded studs adjacent to the Ethernet ports. The studs slide into a mounting
bracket specific to the terminal board type. The bracket location should be adjusted such that there is no right-angle force
applied to the DC-37 pin connector between the I/O pack and the terminal board. The adjustment should only be required
once in the service life of the product.
Note
The I/O pack mounts directly to a TVBA terminal board. This TMR-capable terminal board has three DC-37 pin
connectors and can also be used in simplex mode if only one YVIB is installed to JR1.
4.
Plug in one or two Ethernet cables depending on the system configuration. The I/O pack will operate over either port. If
dual connections are used, the standard practice is to connect ENET1 to the network associated with the R controller.
5.
Apply power to the I/O pack by plugging in the connector on the side of the I/O pack. It is not necessary to remove
power from the cable before plugging it in because the I/O pack has inherent soft-start capability that controls current
inrush on power application.
6.
Use the ToolboxST

application to configure the I/O pack. The following table provides links to some typical
configurations examples based on application (not necessarily any site-specific configuration).
Application
Configuration Example
In Heavy Duty turbine applications, Proximitors are used to monitor the position of a rotating shaft.
In Heavy Duty turbine applications, a Keyphasor is used to calculate the position and rotating
speed of a rotating shaft.
In Heavy Duty turbine applications, Vibration Displacement algorithms report a filtered air gap
value, and peak-to-peak displacement value, and an optional vibration phasor relative to a
specified Keyphasor channel.
Vibration Displacement Application
In LM turbine applications, Velocity sensors are mounted on bearing housings or machine casing
to provide measurements of vibration.
In Heavy Duty turbine applications, Combustion Dynamics Monitoring is used.
