3 Function and System Design WirelessHART Adapter SWA70
10 Endress+Hauser
3 Function and System Design
Wireless Adapter SWA70 Wireless Adapter SWA70 is an intelligent interface module that connects HART and 4...20 mA
devices to a WirelessHART network. It transmits the measurement and diagnosis information
acquired from the connected device to a host application via a WirelessHART fieldgate.
The adapter is availablein both a standard and Ex-version with aluminium or plastic housing. In the
latter case, the connected device must also have the appropriate Ex certification.
The adapter is battery powered. Where appropriate, the battery also provides loop-power to the
connected device. Alternatively, the connected device may be powered externally, see Chapter 5.
Fig. 3-1: WirelessHART network
WirelessHART network The WirelessHART network is self-organizing. After installation and configuration, every wireless
adapter is in a position to recognise its neighbours. It checks the strength of their signals, sychronizes
them, receives frequency information and establishes connection with other participants in the
network. The adapter joins the network automatically without any intervention from the user.

It is recommended that Wireless Adapter SWA70 be installed separate from a field device when:
• there is insufficient space at the measuring point to mount the adapter on the field device
• the signal reception at the measuring point is too weak for correct operation.
• the measuring point is subject to vibration above the permissible limits, see Chapter 11
The adapter can be mounted on a wall, post or other object, using the adapter wall/pipe mounting
kit, which is available as an accessory. The connection to the field device is made with standard
installation cable (and two cable glands). It is recommended that the blind plug be left in place until
the electrical connection is made.

4.6 Final check
To complete the mechanical installation, check the following points:
• Has the adapter been damaged in any way during installation?
Damaged adapters should not be commisioned.
• Does the mounting location fulfil the enviromental conditions for correct operation:
ambient temperature, relative humidity, vibration etc.?
• Is the antenna vertical?
• Does the position of mounting correspond to the requirements in Chapter 4.2?
• Is any mounting bracket correctly mounted and screwed tight?
• Are the adapter piece and counternut screwed tight?
