3.8 Petro-Net Address Jumper Settings
WARNING: Do not change the module jumpers while the module is
energized. The relay positions must not be energized during jumper
adjustment.
When more than one OM4 Module is installed in a system the Petro-Net address must be set in the jumper
block for each module. Each of the modules must be given a different address so they can be correctly
identified in the Petro-Net protocol. The Address block (J4) is located in the bottom left corner of the OM4
board next to the Output 4 connector.
To install two (2) or more OM4 Output Module units:
l
Remove the nuts that attach the aluminum cover.
l
Remove the cover to get access to the circuit board.
l
Set the jumpers to the correct address.
l
Put the aluminum cover back on the unit.
