INSTALLATION GUIDE

OPERATION

The H8920-1 LONTalk Integration Node allows the integration of Veris Industries Enercept H8036 Series power meters with a LON Works control/monitoring system. The H8920-1 converts the 26 power metering data network variables collected by the H8036 as Modbus protocol to LONTalk. Using an indexing technique, the H8920-1 reports the data from up to 63 H8036 Enercept meters on the downstream Modbus network. Adjusting an input variable allows selec tion of the Modbus address of the desired meter. The data is then recorded before selecting another Enercept. The H8920-1 can also be used for binding purposes with a single H8036 meter.

The H8920-1 polls the H8036 meter for its full data set approximately once per second. All output data network variables are immediately updated with this received data. Data exchanged between the node and the meter are fully checksummed to ensure integrity. If corrupt data is detected, the output network variables are not updated and retain their previous value.

PRODUCT DIAGRAM

1. LON Talk Terminal Block: Connect to the LON network at these terminals. This

connection is not polarity sensitive.

2. Shield Terminal Block: Communications shielding for both the LONTalk and

Modbus communications networks.

3. Modbus Terminal Block: Connect to the Enercept Modbus network. This

connection is polarity sensitive; ensure correct polarity.

4. 16-24 VAC/DC Power: Two-wire system power terminal block.

5. TX LED: Indicates transmission of Modbus network data

6. RX LED: Indicates reception of Modbus network data

7. Service LED: Standard LON Works Service LED. Used in concert with the Service

Switch to locally view the commissioning status of the device. LED status after the service switch is pushed:

ON, then OFF solid = Device has been commissioned by a network tool.

BLINK at 1/2 Hz rate = Device has not been commissioned by a network tool.

ON, OFF, then solid ON = Device does not have an application.

8. Identiﬁcation Service Switch: Standard LonWorks Service Switch. Used in

concert with the Service LED to locally view the commissioning status of the device.

9. OP LED: Normally on. The OP LED will blink o when there is an incomplete data

exchange between the meter and the LON node. If this LED is always o, then the meter is not responding to data requests (i.e., the meter is disconnected, unpowered, or incorrectly wired).
