users and maintenance personnel should thoroughly

review this bulletin prior to installing, operating, or

performing any maintenance on the valve.

More detailed operation instructions are included

in the StarPac II / Logix 2000 Manual; refer to them

when more information is needed.

Separate Valtek Installation, Operation, Maintenance

instructions cover the valve (IOM 1 or IOM 27) and

actuator (IOM 2 or IOM 31) portions of the system and

other accessories. Refer to the appropriate instructions

when this information is needed.

To avoid possible injury to personnel or dam-

age to valve parts, users must strictly adhere

to WARNING and CAUTION notes. Modifying

this product, substituting non-factory parts,

or inferior parts, or using maintenance proce-

dures other than outlined could drastically

affect performance and be hazardous to per-

sonnel and equipment, and may void existing

warranties.

WARNING: Standard industry safety practices must

be adhered to when working on this, or any, process

control product. Specifically, personal protective

and lifting devices must be used as warranted.

Unpacking

unpacking the StarPac II / Logix 2000 unit,

check the packing list against the materials re-

ceived. Lists describing the system and accesso-

ries are included in each shipping container.

lifting the system from the shipping container,

position lifting straps to avoid damage to tubing and

mounted accessories. Systems with valves up to

eight inches may be lifted by actuator lifting ring. On

larger systems, lift unit using lifting straps or hooks

through the yoke legs and outer end of body.

WARNING: When lifting a valve/actuator as-

sembly with lifting straps, be aware the center

of gravity may be above the lifting point. There-

fore, support must be given to prevent the

valve/actuator from rotating. Failure to do so

can cause serious injury to personnel or dam-

age to nearby equipment.

the event of shipping damage, contact your

shipper immediately.

any problem arise, contact your Valtek

Control Valve representative.

Tools required for StarPac II / Logix 2000

If the StarPac II is being installed in an insulated process

line, do not place more than four inches of insulation

around the pressure or temperature sensors; otherwise

the sensors may not operate properly. In addition,

NEVER

insulate the unit electronics assembly or

remote-mounted temperature/pressure sensors (when

used).

CAUTION: Do not insulate the StarPac II / Logix

2000 electronics housing or remote-mounted pres-

sure or temperature sensors; otherwise excessive

heat may build up and affect operation.

Wiring and Grounding Guidelines

This section will help you achieve a maximum “noise -free”

environment and performance with a StarPac II / Logix

2000 unit.

Shielding Versus Grounding

All signals to the StarPac II / Logix 2000 unit should be

in shielded cables. Shields must be tied to a ground at

only one end of the cable to provide a place for environ-

mental electrical noise to be removed from the cable. A

ground wire (unlike a shield) is attached at both ends to

provide a continuous path for electrical conductivity.

Grounding Screw

The green grounding screw by the user interface termi-

nal block should be used to provide the unit with an

adequate and reliable earth ground reference. This

ground should be tied to the same ground as the

electrical conduit. Additionally, the electrical conduit

connecting to the unit should be earth grounded at both

ends of its run.

The green grounding screw must not be

used to terminate signal shield wires.

24VDC Power

The 24 VDC connection points will work best with

shielded twisted pair wire with the shield wire connected

INSTALLATION

Valve Installation

The StarPac II / Logix 2000 Intelligent Control System

valve is installed in the same manner as a conventional

control valve and according to industry standards. Refer

to the appropriate valve installation, operation, mainte-

nance instructions for proper installation procedures.
