How to Set Up a Model 494.16 VD/DUC Card
1. Turn off electrical power to the chassis before installing or removing
boards and cards.
The plug-in boards and cards contain static-sensitive components.
Improper handling of boards and cards can cause component damage.
Follow these precautions when handling boards and cards:
•
Turn off electrical power before installing or removing a board.
•
Use a static ground strap to ground yourself to the chassis ground
before touching the chassis or a board.
•
Keep unused boards and cards in conductive bags. Also be sure you
are grounded when removing a board or card from a conductive bag.
•
Handle boards with their front panel or circuit card edges. Do not touch
any circuit card components, pins, or circuit connection points.
DUC cards include components that can be damaged through improper
operation.
Connecting a high-level signal to a DUC when the chassis power is off
can damage the DUC.
Never apply a high-level signal to a DUC when the chassis power is off.
Always remove power from any externally powered devices before you turn
the chassis power off.
2. Use a static ground strap to ground yourself to chassis ground before
touching the chassis or a board.
3. Set up the VD/DUC card(s).
A. (Optional) For transducers that require a ground reference, set the
card grounding DIP switch to the ON position.
B. (Optional) For quarter-bridge transducers, set the bridge-
completion DIP switch on the card to the ON position and install a
bridge completion resistor on the I/O carrier board.
