Page 5: Overview
Overview Congratulations on your purchase of the WattNode Plus for L watt/watt-hour trans- ® ® orks ducer. The WattNode meter offers precision energy and power measurements in a compact package. It enables you to make power and energy measurements within existing electric service panels avoiding the costly installation of subpanels and associated wiring. - Page 7 C: Neutral. On wye models, this terminal must be connected to neutral. On delta models, it is good practice to connect this terminal to the safety ground terminal using a short jumper wire. D, E, F: Mains line inputs. One or more of these terminals are connected to the mains lines. For three phase measurement, the ØA (phase A), ØB (phase B), and ØC (phase C) terminals are used for the three phases.

Page 22: Measurement Troubleshooting
Measurement Troubleshooting There are a variety of possible measurement problems. The following procedure should help narrow down the problem. This assumes you can communicate with the meter and read network variables. Voltage Start by checking the reported voltage (nvoVoltsA, nvoVoltsB, nvoVoltsC) for active (connected) phases. - Page 23 ○ This may be normal if you are measuring in an environment were power may be con- sumed or generated, such as a house with PV panels. ● If one or more phases are reporting low or high power: ○ Make sure the nciCtAmps configuration is set correctly for your current transformers. ○...
- Page 24 ● Florescent lighting: power factor between 0.4 and 1.0. ● Electrical heating: power factor near 1.0. ● Office equipment: power factor between 0.6 and 1.0, reactive power may be positive or negative. Negative power factor values either indicate you are generating power (as with a PV system) or that the CTs are reversed.

Page 25: Network Configuration
Network Configuration Identifying the WattNode The WattNode for LonWorks meter supports three network identification methods. ● Press the meter’s service button when requested by the network installation software. ● Use the meter’s unique Neuron ID to identify the WattNode. ● Use the network wink command to light the meter’s service LED. Service button installation requires that the network management computer be near the meter during installation or that a second person can be near the meter to press the service button. -

Operating Instructions Quick Start To start communicating with a WattNode meter, you’ll need to complete the following steps: ● Make sure you have a working LNS based network management software tool like Lon- Maker with an FTT-10A network interface like the Echelon U10. ®... -
Page 27: Network Variables
Network Variables The WattNode meter uses L interoperable SNVTs (Standard Network Variable Type) and ® is programmed with self-documentation information. It is supplied with an external interface file (XIF), which defines all of the network variables and transceiver parameters. The XIF file may be requested by network management software during installation and is particularly useful if you wish to configure the network software for a meter before physically installing it. -

RQ_NORMAL, RQ_UPDATE_STATUS, and RQ_REPORT_MASK requests are supported. You can make a request of the entire meter with using the NodeObject or one of the functional blocks. In response to each request, the object’s status is returned in nvoStatus. The status variable nvoStatus also indicates if the request was made of an invalid object number, or if the object doesn’t support the request made of it. -

nvoDemandPk This is the largest measured positive demand value. It is preserved across power fail- ures. nvoDemandPk and nvoPeakDemT can both be reset to zero by writing 1 to nviResetPkDemand. nvoPeakDemT This is the date and timestamp at which the peak demand value was measured. This is cleared whenever nvoPeakDemT is reset to zero with nviResetPkDemand. -

SCPTmaxSndT This property is used to configure the rate at which the meter updates bound measurement network variables, such as nvoPowerSum. The update rate for all measurements except demand are controlled by nciMaxSendT. This setting only applies to bound network variables, because it controls the rate at which network variable updates are transmitted over the network. -
Page 37: Wattnode Errors
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. -
