The FCS-9000 range of enclosures are manufactured from polished

316 stainless steel to provide the highest levels of corrosion

resistance for the harshest process environments.

The FCS-96xx Process JBs are suitable for Zone 2 and Zone 1

intrinsically safe (Ex i) and increased safety applications.

The fieldbus junction boxes are available pre-drilled for one

segment: having trunk-in, trunk-out and 4 spur connections; or a

trunk-in and 8 or 12 spur connections; or two segments having a

trunk-in and 24 spur connections. Two-pair multicore trunk cable

may be used when only a single trunk gland is available.

For temperature multiplexer applications, junction boxes are

available for a single MTL831C with a data highway in and 16

sensor connections and for 2 MTL831C units with a data highway

in and 32 sensor connections.

The wide choice of glands, including stainless steel and nickel

plated brass, enables a high quality seal with standard or wire

armoured cables.

The box incorporates a rain channel that prevents standing water

from damaging the one-piece seal; diverting it away from the

contents when the door is opened. A 10mm earth stud and a

breather are also included as standard.

An adhesive backed, Traffolyte tag label is supplied loose or can be

engraved with the tag number and fitted, if details are supplied

when ordering.

The FCS-9000 series that provide strength, durability and corrosion

resistance to many chemicals and their vapours. The enclosures are

manufactured from 316 stainless steel to provide the highest level of

corrosion protection.

A wide choice of glands is available, ready fitted to the junction box:

stainless steel and nickel-plated brass enabling a high quality seal with

standard or wire-armoured cables. All glanding is in the base of the

enclosure with a minimum of 75mm of clearance between the base of

the enclosure and other components. This makes glanding much easier,

especially when terminating armoured cable.

Significant cost savings can be made on a fieldbus project by selecting

standard, and proven, fieldbus junction box designs. It eliminates the

need for custom designs when choosing junction boxes for fieldbus

applications and saves the cost of managing the specification and the

eventual procurement of the junction boxes.

To select the Process JB appropriate to your application; first

determine the number of fieldbus device connections, and hence the

number of spur connections required in the junction box. This will

also define which Megablocks (and maybe terminators) are required.

Use the application examples to help you. For MTL831C applications,

the enclosure choice will depend on the number of transmitters

(maximum 2 x MTL831C) to be fitted inside the enclosure.

Identify any additional items that will need to be housed in the

enclosure, e.g. terminals for terminating spare cables, Ex ic adaptor,

additional terminators, etc. Calculate how much DIN rail they will

require. Add this to length of the Megablock(s) and choose an

enclosure with sufficient rail length.

Eaton’s MTL Process JBs are designed for mounting Megablock

fieldbus wiring components, terminators, F30 Ex ic adaptor, 9320

spur connections, surge protection devices and MTL831 Multiplexer

transmitters in order to meet the exacting requirements of process

industry customers.

MTL wiring components are established as the industry standard

for fieldbus device connections and are combined with Crouse-Hinds

junction box and cable glands in the Process JB product range.

Process JBs make it easy to install and maintain the fieldbus system.

For example, a minimum of 75mm (3”) of clearance is provided

for fieldbus cable connections. This ensures that the correct bend

radius is maintained when connecting to the full range of MTL wiring

components.

For applications where communication paths with several field devices

need to be established and maintained in parallel, the Crouse-Hinds

series MTL4854 HART multiplexer is the ideal product to use.

This is a module that has the same 32 channel capacity as the MTL4850

for connection to field devices, but also has four HART modems rather

than just one.

Essentially, this gives 4 x 8 channel multiplexers in one compact housing,

enabling simultaneous communication with several field devices through

one serial link. One particular use for this is during partial stroke testing

of valve positioners, where the ability to maintain access to other

connected devices while the multiplexer would otherwise be locked

enables plant monitoring to continue.

INSTALLATION AND ELECTRICAL

CONNECTIONS

2.1 Installation and Mounting of the Controller

Carefully unpack the controller and inspect thoroughly. It is

recommended that the controller is located as close as is

practical to the motor it controls.

The controller is not free standing and must be bolted securely

to a wall. For dimensional and weight data please refer to the

respective data sheets for the Jockey Pump Controller.

2.2 System Pressure Connection

The Jockey Pump Controller is equipped with a Pressure

Transducer. The controller is provided with a ¼” NPT female

system pressure connection located on the bottom, external

side of the enclosure.

NOTE: Water lines to the pressure transducer must be free from

dirt and contamination. The pressure should not exceed what

the pressure transducer is rated for.
