INSTALLING AN OPTION CARD
Caution: The option and main circuit cards contain static
sensitive components. Before handling the cards, discharge
static charges from your body by touching a grounded bare
metal object. Ideally, handle the cards at a static controlled
clean workstation. Also, only handle the cards by the edges.
Dirt, oil or other contaminants that may contact the cards can
adversely affect circuit operation.
Warning: Exposed line voltage exists on the circuit boards.
Remove all power to the meter AND load circuits before
accessing the unit.
1. Remove the main assembly from the rear of the case. Squeeze the finger
holds on the rear cover, or use a small screwdriver to depress the side
latches to release it from the case. It is not necessary to separate the rear
cover from the main circuit card.
2. Locate the option card connector for the type of option card to be
installed. Hold the unit by the rear connector, not the display board, when
installing an option card.
3. Install the option card by aligning the option card connector with the slot
in the rear cover. The cards are keyed by position with different main
board connector locations. Be sure the connector is fully engaged and the
tab on the option card rests in the alignment slot on the display board.
4. Slide the assembly back into the case. Be sure the rear cover latches fully
into the case.
5. Apply the option card label to the bottom side of the meter. Do not cover
the vents on the top surface of the meter. The surface of the case must be
clean for the label to adhere properly. Apply the label to the area
designated by the large case label.
6. See manual for wiring connections and programming procedures.
DESCRIPTION
The DeviceNet Option Card (PAXCDC30) is designed for the PAX series of
meters. It fits into the Comms slot of any PAX meter and allows the meter to
communicate with a DeviceNet bus. The card supports Polling, Bit Strobe, and
Explicit Message Commands. The MAC ID and the Baud Rate are switch
adjustable via a DIP switch. A bicolor LED is used to indicate the meter’s status
in relationship to the bus.
