CHAPTER 1 GENERAL
1.1 Product Introduction
The Wireless Field Interface (WFI) adds a wireless capability to the
existing servo or the radar gauge by supporting the GPU protocol which
is compliant with the ISA100 standards. It consists of multiple electronic
boards, an antenna cable, and an antenna. The WFI communicates
with the servo or the radar gauge through the Honeywell Enraf field bus
Bi-Phase Mark, processes the data, and forwards the information
wirelessly to the Wireless Device Manager (WDM) which is compliant
with the ISA100 standards. The complete network including the WFI is
based on the ISA100 wireless field device network.
Also, there are different ways of communication which are as follows:
The protocol tunnel (Engauge and Entis)
Function blocks (Experion integration)

CHAPTER 3 SYSTEM DESCRIPTION
3.1 Introduction
3.2 System Architecture
The WFI is a box that can be installed next to an installed Servo/Radar
gauge. The WFI retrieves the information from this gauge and sends the
information wirelessly to the supervisory level.
This is an ISA100 compliant solution that supports transducer blocks for
transferring basic process values to the supervisory level and supports
the GPU tunnel to connect to the Engauge (maintenance) and Entis
(inventory management package) systems. See FIGURE 3-1.

3.3.4 Field Wiring
The mains input and the CAN-BPM signal lines enter the enclosure
through different glands from one side of the enclosure.
The mains input (Line and Neutral) cable wires terminate on the PSX
module connector. The mains input earth wire terminates on one of the
PE points provided inside the enclosure. From the PE point inside the
enclosure, the PSX gets the PE connection through the wire terminated
on the PSX connector.
The CAN-BPM signals cable from the servo gauge enters the enclosure
with the gland and terminates on the CAN-BPM module connector. The
CAN-BPM module then gets the earth wire from the PE point inside the
enclosure. See FIGURE 3-6.

CHAPTER 4 INSTALLATION
4.1 Mounting the Antenna
The antenna is placed on top of the WFI enclosure as shown in the
following figure.
FIGURE 4-1 WFI antenna
To mount the communication antenna on the WFI device, screw the
communication antenna clockwise on the lightning arrestor. See
FIGURE 4-2.

FIGURE 4-2 Mounting the communication antenna
NOTE: The lightning arrestor protects the inside electronics
from the lightning damage. Although it protects
against multiple discharges, it can be replaced as a
preventive maintenance action. Preventive main-
tenance interval depends on the location, position of
the equipment, grounding, and other protection
measures installed.
4 dBi and 8 dBi integral antenna’s are supported in WFI.
For more information about the antenna types supported, refer to the
SmartRadar FlexLine Service Manual.
