configured – see section 6:
1. Remove the FieldKey from the box.
2. Attach the antenna.
3. Attach the FieldKey to the field instrument (remove the
antenna to help rotate the housing).
4. Rotate housing for best antenna direction (normally vertical).
5. Lock the FieldKey via the locking nut and set or grub screw.
6. Make electrical connection to the FieldKey (see Section 5)
and then wait at least 3 minutes.
7. Connect HART configuration tool and set Network ID, Join
Key and FieldKey Tag.
8. Set the join mode to Join Now.
9. Monitor the join status.
3Mechanical installation
The WirelessHART adapter can be fitted in the following ways:
Via a spare instrument cable gland.
If no cable gland is available use the T-Piece (option).
Connect the adapter at a junction box located in the 4 to
20 mA signal loop.
4Antenna direction and locking
The antenna can be rotated through almost 360° and fixed in
place by rotating the locking nut and tightening the set or grub
screw with the Allen key.
The best position for the antenna is often in a vertical direction.
European countries only.
