DRAFT - 11 March 2016 DRAFT - 11 March 2016
1 OVERVIEW
The F860 is designed to provide redundant power for eight
Foundation™ fieldbus H1 segments when used with Honeywell
Experion "Series C" Fieldbus Interface Modules (FIMs). The module
carrier complies with the mechanical and electrical requirements
of 11.6 inch I/O Termination Assemblies (IOTAs), for direct fitting
into Honeywell mounting channel. Power for the fieldbus segments
is provided by two power modules - F801 or F802 - operating
in a redundant configuration. Failure alarms, galvanic isolation,
power conditioning and segment termination are incorporated into
each F80x module. In simplex applications, a single F80x module
may be used. Termination of the fieldbus segments is automatically
maintained when single or redundant F80x modules are fitted.
2 DESCRIPTION
For extreme reliability, the F860 IOTA is passive and only provides
interconnections between the power modules and the external
connections.
The IOTA has two multi-pin connectors, each of which is connected
to a FIM IOTA by means of a standard system cable. Different
lengths are available, to accommodate mounting of the F860 and
its respective FIM IOTAs in various locations within a Series C I/O
cabinet. Field wiring is connected at the FIM IOTA.
Each F80x module provides galvanic isolation between the 24V
DC input power and the fieldbus segments, as recommended by
the IEC61158-2 fieldbus standard and the Fieldbus Foundation™
FF-831 validation test for power conditioners. There is galvanic
isolation between the fieldbus segments, thereby preventing segment
failure in the event of ground faults in the field wiring.
Each F80x module has indicator LEDs to show both its status and that
of the eight segments under power. In normal operation, each green
'Segment' LED is lit, showing that the segment is powered. If a segment
is shorted, this LED is extinguished, and the red 'Alarm' LED is lit.
An alarm is also triggered by faults inside the F80x modules, or by
the loss of 24V DC power to either module. In an alarm condition
affecting any of the 8 segments, both FIM IOTAs are alerted via
dedicated signal lines in the interconnecting cables. Separate digital
input modules are not needed to detect alarms.
A separate F809F physical layer diagnostics module may be installed
onto the IOTA, to automatically collect and distribute additional
diagnostic information on each of the eight fieldbus segments. Refer
to the separate F809F data sheet for more information.
Power for the IOTA is taken via mounting screws from 24V DC
busbars that are embedded in the Series C mounting channel.
Alternatively, for installations in which the internal Series C power
supplies are unable to provide sufficient current capacity, two
independent external 24V DC supplies (for redundancy) may be
connected to the IOTA via two-part pluggable connectors. Each F80x
power module is protected by its own replaceable anti-surge fuse, to
provide reliable bulk power.

4 MECHANICAL
The layout and dimensioning of the F860-CA IOTA is shown in Figure 2.
The IOTA is fixed to the channel with six M3 mounting screws (A),
together with the two screws used to connect to the 24V DC and 0V
busbars (Band C).
The total weight is approximately 3.2kgs with two F801 power
modules fitted and 3.3kgs with F802s.
5 INSTALLATION
For all aspects of the F860-CA specification refer to its datasheet
EPS F860.
5.1 Mounting
It is assumed for the purposes of these installation instructions that
the mounting channel is already fitted in a cabinet or enclosure that
provides a suitable environment for the FIMs and their associated
equipment. Such an environment will be suitable for the F860-CA
IOTA.
These mounting instructions may be followed regardless of whether
the IOTA has modules fitted or not.
It is important to ensure however, that the mounting channel is
positioned in a vertical orientation on a vertical surface. This is
regarded as the optimum mounting orientation for the F860-CA IOTA
and ensures that it will perform to specification within its specified
operating temperature range.
5.1.1 Mounting the carrier
Mount the IOTA to the channel in the orientation shown in Figure 2.
Only when it is in this orientation will it be able to pick up the power
bus connections thorugh screws Band C.
Position the IOTA, then secure it using the six fixing screws - marked
Ain Figure 2.
Note: The head of one of them is accessable only while the F809F
is not in position on the IOTA.
5.2 Input power connections
There are two methods of obtaining the 24V DC input supply:
from the I/O channel or
from independent external sources - use two for redundancy
The connectors (CON9 & CON10) located at the top right of the IOTA
are used to receive, or configure the source of, the IOTA’s incoming
power.
Note: Attention should be paid to the in-rush current when sizing the
source of DC power. See the specification in Section 8.
5.2.1 Incoming DC supply from mounting channel
Busbars located at the rear of the I/O mounting channel normally
provide 24V DC power for the IOTAs fitted to it.
If this is the chosen method of obtaining the input supply, CON9 &
CON10 should have wire links connected as shown in Figure 3A.

A
Figure 5: Electrical block diagram of F860
If CON9 & CON10 have been wired for this configuration, engage
and tighten the screws - marked B(24V) and C(0V) in Figure 2 - to
make the connections to the channel busbars.
5.2.2 Incoming DC supplies from external sources
If redundant external 24V DC sources are chosen to power the F860
then connect one incoming supply into CON9 as shown in Figure 3B
and the other, using the same method, into CON10.
Note: The cables providing 24V power to the F860 should not
exceed 30m in length, nor go outside the building.
5.3 Output power connections
There are two output power connectors on the F860-CA IOTA:
CON5 providing power for segments 1 – 4 and
CON6 providing power for segments 5 – 8.
CON5 provides power to the first four segments from both F80x power
modules, assuming two are fitted. Similarly, CON6 provides power to
the other four segments (5 - 8) from both F80x power modules. In this
manner redundancy is provided for both groups of segments.
Choose the most suitable length of cable to make the connection from
the F860-CA IOTA to the associated FIM - with reference to the parts
list in Section 3 of this manual. Lengths of 30cm (~1ft), 1metre (~3ft
3in), 2metres (~6ft 6in) and 4m (~13ft) are available.
Plug-in one end of the cable to CON5, which is controlled with a
keyway to prevent an incorrect connection, and the other end should
be routed carefully to the FIM IOTA and the connector inserted there;
again with due care for its orientation. Repeat this procedure for
CON6 and the second FIM if required.
5.4 Mounting and removal of F80x
power modules
The F80x power modules are secured to the carrier with four screw
mountings.
Mount the F80x over its electrical connector on the carrier and hold
it in place while tightening the four fixing screws.
To remove an F80x power module, support the module while unscrewing
the four fixing at its base. Lift the module off the carrier connector.
5.5 Redundancy
In order to obtain redundant operation, F80x modules must be fitted
in both the 'A' and 'B' locations.
If non-redundant operation is required, fit an F80x in location 'A'
only. In this case, to prevent an alarm condition, caused by the
absence of the second F80x, a blanking module (see Figure 4) should
be fitted in its place at location 'B'.
5.6 Terminator
Terminators are built in to the F80x modules and a single terminator
is provided automatically on each segment regardless of whether one
or two F80x Power Modules are in use.
5.7 Alarms
If the output voltage from an F80x power modules to one or more
fieldbus segments should drop below 19V the ‘Alarm’ LED indicator
on the module will light. The alarm condition is also communicated
to the FIMs via the FCAB connecting cables.
5.8 F809F Diagnostics Module
The F860-CA has provision for the mounting of an F809F Fieldbus
Diagnostics Module, which will continuously monitor the performance
of each of the eight fieldbus segments, providing information on the
network health and capturing retransmissions between the fieldbus
devices and control system.
The F809F is a Foundation fieldbus™device, and communicates with
the host control system via a fieldbus segment. This allows the network
status and measured parameters to be displayed in the host control
system using proprietary instrument management software.
See instruction manual INMF809F for full details of configuration
and operation of this module.
5.8.1 Mounting F809F module
Position the module as shown in Figure 2 or 5 and press the
module on to the IOTA connectors. Tighten the two mounting screws
sufficiently to hold the module in position.

6 TESTING
6.1 F801 Status and Alarm LEDs
F80x power modules are fitted with nine LEDs, eight to indicate
segment status and one to signify an Alarm condition.
7 MAINTENANCE
7.1 Routine maintenance
Check the general condition of the installation occasionally to make
sure that no deterioration has occurred. At least every two years (and
more frequently for particularly harsh environments) check:
◆the condition of wire connection/terminations/screens.
◆the dc output voltage on each of the four fieldbus
segments is >21.5V. This can be performed using a
multimeter or a Relcom FBT-3/FBT-6 fieldbus tester.
◆that the segment LEDs on the F801 module(s) are
functioning and the Alarm LED(s) is not lit .
◆that the retaining screws are tight.
◆that there are no signs of damage or corrosion.
7.2 Fuse replacement
Two anti-surge (slow-blow) fuses, FS1 & FS2, rated at 10A each, are
incorporated on the IOTA to protect the system from short-circuit fault
conditions. One fuse (FS1) supplies the F80x (A) module and the
other (FS2) supplies the the F80x (B) module.
Should it be necessary to check or replace the cartridge fuse in
either of the fuse holders, the appropriate incoming supply should be
isolated before any further action is taken.
Insert a flat-bladed screwdriver in the slot on top of the fuse holder
and rotate it counter-clockwise as far as the stop (approx. 45°). The
fuse cartridge holder will pop out and may then be extracted.
If a fuse is found to have blown, it is important to clear the fault before
replacing it with a new one.
