INSTALLATION GUIDE

OPERATION

The H8920-4 LONTalk Integration Node allows the integration of Veris Industries
H704 and H663 Series branch current monitors (BCM) with a LON Works control/
monitoring system. The H8920-4 converts the metering data network variables
collected by the BCM as Modbus protocol to LONTalk. Using an indexing technique,
the H8920-4 reports the data from up to 63 BCMs on the downstream Modbus
network. Adjusting an input variable allows selection of the Modbus address of the
desired meter. The data is then recorded before selecting another BCM. The H8920-4
can also be used for binding purposes with a single BCM.

The H8920-4 polls the BCM 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 H704/H663 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).

INSTALLATION GUIDE

INSTALLATION

1. Remove screws from the lid of the H8920-4 housing. Lift lid and remove wire
guide caps. Set aside with the lid.

2. Bring the H704/H663 RS-485 network
cable to the Modbus terminal block
marked +MB-. Thread wires through wire
guide before terminating. Connect the (+) to TB6.
Connect the (-) wire to TB5. Connect the shield
wire to TB4.

3. Bring the LON Works network cable to the
terminal block marked BA LON. Thread wires
through wire guide before terminating. Connect
the A wire to TB1. Connect the B wire to TB2.
Connect the LON network shield wire to TB3.

4. Connect the 16-24 VAC/DC power wires to TB7 and TB8. The power terminals are
not polarity sensitive. This power source must be separate and isolated from other
circuits to prevent unwanted "ground loops."*

5. Thread wires through the most convenient openings in the housing.

6. Re-attach the lid and snap wire guides into place. Replace screws to hold the
housing together.

7. Mount the H8920-4. The device can be ush mounted to a wall, screw mounted to
a 2 or 4s electrical encosure, or nipple mounted to an existing enclosure. Mount
the H8920-4 in a class 2 environment.

8. Refer to the H704/H663 installation instructions for connection of the LON node to
the BCM.

* Veris transformers such as X020xxx, X040 xxx or X050xxx or DC power sup plies such as PS-24-7.5,
15, or 30 fulll these requirements. If the installatio n only has non-isolated 24 VAC available, then
a Veris transformer such as X020ADA can provide the necessary isolation.

CONFIGURATION

1. Upon powering up, the OP-LED is lit.

2. During operation, the OP-LED turns o if either of the following occurs:

a) No Modbus requests are generated by the unit for 10 seconds. This occurs
with new units (which have yet to be commissioned) or any units which
are in "Uncongured," "O-Line" or "Disabled" LonTalk states. Under these
conditions, the neuron chip will not generate requests to the Modbus
network.

b) No response or an error response from the Modbus network (e.g. no meter
attached, wrong type of meter (H8035 instead of H704/H663), broken RS-485
wir es, etc.).

3. If the OP-LED is OFF for any reason covered in step 2 above, it will be re-lit when a
correct response is received from the Modbus network.

4. Under Condition 2b above, the oating-point SNVT data will be replaced with
oating-point-not-a-number (NaN,0x7FC00000), indicating to the remote user
that the data is no longer valid.

Index Feature

By adjusting the network input variable nviMeter Index, the Modbus address used to
populate all of the NVOs can be changed. This option is used to view and archive
data from a Modbus network of up to 63 H704/H663 BCMs. Using this feature
eliminates the possibility of binding any points from the node. If the application
requires binding, the LON node can only view one BCM.

Using the Meter-Index Function

To ensure that the data read from the unit corresponds to the correct meter, follow
this algorithm:

1. Change nviBCM Index to the desired BCM.

2. Wait for nvoBCM Index to change to the same value as nviBCM Index. Do
not read data from the unit until this occurs: You will not be able to determine
which BCM the data corresponds to until nvoBCM Index=nviBCM Index. Do
not use "time-delays" to wait for the new data to be valid.

3. Once nvoBCM Index=nviBCM Index, you may poll values with the
assurance that the data corresponds to the desired BCM.

Power Meter Configuration

If binding is required, use Modbus address 1 for the BCM. When employing the
indexing method, use addresses 1-63. Please refer to the H704/H663 Installation
Instructions for meter addressing information.

Auto Propagate Feature

The H8920-4 automatically propagates all network variables. If nciMaxSendTg is
set above zero (default is zero), all variables are propagated periodically. Units are
in tenths of a second. For example, if nciMaxSendTg is set to 100, the H8920-4 will
automatically propagate all variables every 10 seconds.
