1 Safety
1.1 Designated use
Fieldgate FXA520 is a HART Interface/Gateway with integrated web server that is used for remote
acquisition of data from up to 30 measuring points. Two HART devices and two analog devices can
be connected directly to it. Additional HART devices can be connected via the HART multidrop
adapter FXN520 or via a HART multiplexer. When used in connection with the FXZ520 multiplexer
module, it is also possible to access values provided by up to 28 4...20 mA and digital devices. The
Fieldgate communicates with the host computer via Ethernet, telephone or GSM modem.
Fieldgate FXA520 may also be used together with FieldCare for the remote diagnosis and
parametrization of connected HART devices.
1.2 Installation, commissioning and operation
Fieldgate FXA520 must be installed, connected, operated and maintained according to the
instructions in this manual: personnel must be authorised and suitably qualified.
1.3 Operational safety
The unit may only be operated under the permissible ambient conditions given in the technical data.
Explosion hazardous areas
Fieldgate FXA520 itself may not be mounted in explosion hazardous areas.
An Ex-version exists with two intrinsically safe HART channels. These may be used to connect
HART devices of Category 1D or 1G operating in a hazardous area. Safety Instructions XA188F-A
give details on installation in hazardous areas.
Repair
Do not open the housing of the Fieldgate FXA520. It does not contain any parts that need to be
maintained or repaired by the user. In the event of a fault or defect, return the unit to the vendor.
Opening the unit will void the warranty!
1.4 Technical improvement
Hauser reserves the right to make technical improvements to its hardware and software at
any time and without prior notification. Where such improvements have no effect on the operation
of the equipment, they are not documented. If the improvements effect operation, a new version of
the operating instructions is normally issued, see Revision History.
