A20830

The flow-through sensor (A20830) requires gas flow past the sensor. The unit has specific inlet
and outlet ports, which are labeled on the unit and shown in the figure below.

The unit comes with 1/8” FNPT threaded ports in which two stainless steel compression fittings
have been plumbed. The compression fittings are sized to handle ¼” OD tubing.

This unit is designed to be mounted to 35 mm DIN rail.

Modbus

A20829

The in-situ H

2

sensor has DIP switches located inside of the enclosure for setting the Modbus

address. The Modbus address is set to 1 by default. Photos below show where the DIP switches
are located inside of the enclosure. The DIP switch settings for each address are given in
Appendix A.

To gain access to the DIP switches:

1.

Verify that the unit is not powered. Unplug the power connector to remove power.

2.

Remove the four (4) 6-32 screws to remove the front cover plate.

3.

Carefully, pull the cover plate off of the enclosure. The cover plate has a circuit board
attached to it, which is connected to the enclosure via several wires. Be careful not to
damage the wires or circuit boards.

4.

The DIP switches are located on the circuit board mounted to the back of the cover plate.

5.

Move the DIP switches accordingly for the Modbus address listed in Appendix A.

6.

When reassembling the unit, be careful of wire locations. Some wires may need to be
positioned to the side or behind circuit boards in the enclosure in order to get the cover
plate on the enclosure properly.
