Ydoa Installation; To Install The Ydoa Pack - GE Mark VIeS System Manual

6.1.2 YDOA Installation

➢ ➢ To install the YDOA pack
1. Securely mount the desired terminal board.
Directly plug one YDOA for simplex or three YDOAs for TMR into the terminal board connectors.
2.
3. Mechanically secure the 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 connector between the pack and the terminal board. The adjustment should only be required once in
the life of the product.
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 pack by plugging in the connector on the side of the I/O pack. It is not necessary to insert this
connector with the power removed from the cable as the YDOA has inherent soft-start capability that controls current
inrush on power application.
6. Use the ToolboxST application to configure the YDOA as necessary.
6.1.2.1 Connectors
• A DC-37 pin connector on the underside of the YDOA connects directly to a discrete output terminal board.
• An RJ-45 Ethernet connector named ENET1 on the pack side is the primary system interface.
• A second RJ-45 Ethernet connector named ENET2 on the pack side is the redundant or secondary system interface.
• A 3-pin power connector on the pack side is the input point for 28 V dc power for the pack and terminal board.
Note The terminal board provides fused power output from a power source that is applied directly to the terminal board, not
through this pack connector.
