Checking Addressing and Wiring for System Components
Once you have set the number of stations and pumps as described previously, you should verify that the controller is communicating with all stations, pumps, and central alarms, and with the ArmorBlocks for all central purge valves. To do so:
1.At the System Setup screen, touch DeviceNet Node Status near the lower right of the screen.
The DeviceNet Node Status screen appears:
2.Check that the expected components are shown as present (green) and not present (black). (Disregard any error messages.)
For example, if you have 18 stations, boxes 01 through 18 in the Stations section should be green and boxes 19 through 50 should be black. For central purge valves, you should see a green box for each ArmorBlock installed.
If the screen display is not as expected, either a component’s ArmorBlock has an incorrect address or the ArmorBlock is not correctly wired to the network.
When you have verified that the controller is communicating with the other system components, you should verify that the inputs on all ArmorBlocks for stations and pumps are wired correctly and are working correctly. To do so:
1.At the DeviceNet Node Status screen, touch DeviceNet Input Status near the lower right of the screen.
