WattNode Errors
The WattNode tracks internal errors and warnings. The most recent error is logged and preserved
over power failures so that it can be recovered by the WattNode Plug-in or by any network man-
agement tool. With LonMaker you can check the “Error Log” using the Manage / Test command.
For errors, contact CCS, because the WattNode may need service. Warnings can generally be
disregarded unless they occur repeatedly. Note: there is no way to read errors using network
variables.

Maintenance and Repair
The WattNode for LonWorks meter requires no maintenance. There are no user serviceable or
replaceable parts except the pluggable screw terminals.
The WattNode meter should not normally need to be cleaned, but if cleaning is desired, power
must be disconnected first and a dry or damp cloth or brush should be used.
The WattNode meter is not user serviceable. In the event of any failure, the meter must be
returned for service (contact CCS for an RMA). In the case of a new installation, follow the diag-
nostic and troubleshooting instructions before returning the meter for service, to ensure that the
problem is not connection related.
