2.2.2.2 Commissioning
The commissioning of the device is conducted by qualified engineers
trained by Honeywell Enraf and with the knowledge of the (local and
national) requirements for electrical equipment in (potentially) explosive
atmospheres.
2.2.2.3 Maintenance and troubleshooting
If the WFI device does not function accurately, only a qualified service

2.2.2.4 Grounding
 Make sure the housing of the device is properly connected to ground
reference. See FIGURE 4-5 and FIGURE 4-6.
 Make sure the electrical resistance of the ground connections is
below the maximum prescribed by local requirements.
2.2.3 Electrical
2.2.3.1 Safety Standards
 Do not open the enclosure when an explosive atmosphere may be
present.
 The entire electrical installation must be in accordance with the International Standard EN IEC 60079-14 for electrical equipment in
hazardous areas. Alternatively as per National Electrical Code
(NFPA70) or Canadian Electrical Code requirements. All electrical
installation is dependant on applicable national and/or local regulations.





threaded adaptors, cable glands and their interface with the housing
must also comply with IP66/IP67 requirements.
In order to withstand the explosion pressure the bolts have to be
fastened with a moment 16Nm (13.5 to 17.8 Nm). The bolts are
captured types (property class A2-70 or better) and are not user
replaceable. Contact Honeywell Enraf if you have or even suspect a
need for replacement bolts.
Use only Explosion proof (Ex d) compound cable glands or conduit
seals, (choice between the two is dependent on local requirements).
When using conduit seals, they shall be installed within 18 inches
from the enclosure.
Unused cable entries must be sealed with an approved threaded
stopping plug. Thread type (metric or NPT) and sizes vary; consult
the manual to make absolutely sure that the correct type is placed.
Improper installation of cable glands, conduit or stopping plugs will
invalidate the Ex approval.
Intrinsically safe cabling may only be connected to the outside 5 pin
socket. Connection of non-intrinsically safe signals will invalidate the
approval. The electrical data of the intrinsically safe circuits is to be
taken from the ATEX/IECEx certificate (numbers see below) which is
shipped with the instrument.
Accurate dimensions of the flame-proof joints must be used. Contact
Honeywell Enraf for information regarding the dimensions of the
flame-proof joints.

CHAPTER 3 PRODUCT DESCRIPTION
3.1 Wireless Field Interface
The Wireless Field Interface (WFI) adds a wireless capability an existing
servo or the radar gauge supporting the GPU protocol. This wireless
communication is ISA100 compliant. It consists of multiple electronic
boards, an antenna cable, and a communication antenna. The WFI
communicates with the servo or the radar gauge through the Honeywell
Enraf physical layer, processes the data, and forwards the information
wirelessly to the Wireless Device Manager (WDM). The complete
network including the WFI is based on the ISA100 wireless field device
network.
There are different ways of communication which are as follows:
 The protocol tunnel (Engauge and Entis)
 Function blocks (Experion integration)

through a cable. The connections to the Wireless Field Interface are
made inside the optional FlexConn module. The cable has four wires, a
shield and an optional a ground wire.
Mount an M20 cable gland to the Standalone SmartView, and connect
the other end to the external display connector located on the WFI
device.
WARNING! Intrinsically safe cabling may only be connected to
the outside 5 pin socket. Connection of non-intrinsically safe signals will invalidate the approval. The
electrical data of the intrinsically safe circuits is to be
taken from the ATEX/IECEx certificate (numbers see
below) which is shipped with the instrument. Any
deviation from the recommended FII-SMV cable
routing or Coax Cable routing invalidates the Ex
approvals.

3.3 FlexConn Modules
One of the main characteristics of the FlexConn architecture is the
placement flexibility of the FlexConn modules. Inside the enclosure, the
following modules are available.
 FII-SMV or optional Module
 HCI-1WL
 FCM-BPM
 CAN-PSX
One end of the terminating resistor is placed on the CAN-PSX module.
The other end is placed on the optional module (FII SMV board), if it is
in use.
FIGURE 3-3
FlexConn CAN bus concept
If an optional board is not used, the other end of the terminating resister
must be placed on the HCI-1WL module (the last module).

Part No.: 4417781
Product Description
NOTE: 1/2’’ NPT entries are provided by default. 3/4” NPT
adaptors are provided on order.
The temperature
rating of the glands
must be at least 20ºC
[68ºF] above
maximum operating
temperature.
Therefore, a rating of
85°C [185ºF] is
suitable for the entire
temperature range.
FIGURE 3-7

CAUTION! Only use explosion proof or flame proof certified
materials of an appropriate IP value.
CAUTION! Unused cable entries must be sealed with an
approved threaded stopping plug. Thread type
(metric or NPT) and sizes vary; Improper installation
of cable glands, conduit or stopping plugs will
invalidate the Ex approval. If the SMV connector is
removed or is not factory installed, the entry should
be fitted with an approved flameproof stopping plug.

4.6 Replacing the Lid
1. Ensure the O-ring of the lid is in place and not damaged.
2. Ensure the spigot faces are not damaged or contain dirt.
CAUTION! Do NOT apply sealant to faces and minimize the use
of grease!
3. Ensure cables are clear of spigot face when re-inserting the lid.
4. Rotate gently to aid insertion.
5. Mount the 3 captive socket-head screws, and the W&M bolt. W&M
Bolt must be fastened close to the sealing post on Lid cover
6. Tighten the bolts with an 8 mm Allen key. Tighten with 16 Nm.
In order to withstand the explosion pressure the bolts have to be
fastened with a moment 16Nm (13.5 to 17.8 Nm). The bolts are
captured types (property class A2-70 or better) and are not user
replaceable. Contact Honeywell Enraf if you have or even suspect a
need for replacement bolts.

The following mounting options can only be considered as suggestions.
You may choose other appropriate mounting options as long as the WFI
communication antenna is always pointing up.
 The WFI may be mounted on a pipe railing using a mounting bracket
and M10 socket-head bolts or U-ring bolts. This mounting bracket is
not a part of the WFI product.

replaced as a preventive maintenance action. The
preventive maintenance interval depends on the
location, position of the equipment, grounding, and
other protection measures installed.
For more information about the antenna types supported, refer to the

All fusing is performed internally on the CAN-PSX board (includes a
1.25A, 250V rating fuse). The CAN-PSX module powers the other 3
modules and so no external fusing is required.
NOTE: Fuse is not user replaceable. Contact Honeywell
Enraf you need assistance with the fuse.
5.2.2 Power Consumption
Typical
6.4W at 24V/ 230V
I dc = 262mA
I ac = 64.3 mA
Maximal
7.4W (AC input)
6.48W (DC input)
NOTE: Ex certificates are invalidated if the total internal
power dissipation exceeds 12 W.
