GENERAL INFORMATION

INTRODUCTION

Rotork Process Controls designs, manufactures, and
tests its products to meet many national and interna­tional standards. For these products to operate within
their normal specifications, they must be properly

• Follow all warnings, cautions and instructions marked
on, and supplied with, the product.

• Inform and educate personnel in the proper installa­tion, operation and maintenance of the product.

• Install equipment as specified in Rotork Process
Controls installation instructions and per applicable
local and national codes. Connect all products to the
proper electrical sources.

• To ensure proper performance, use qualified person­nel to install, operate, update and maintain the unit.

• When replacement parts are required, ensure that
the qualified service technician uses replacement
parts specified by Rotork Process Controls. Substitu­tions may result in fire, electrical shock, other haz­ards, or improper equipment operation.

• Keep all product protective covers in place (except
when installing, or when maintenance is being
performed by qualified personnel), to prevent
electrical shock, personal injury or actuator damage.

• Operation of actuator in an inappropriate fashion
way cause harm or damege to unit or other equip­ment/surroundings

WARNING

Before installing the actuator, make sure that it is
suitable for the intended application. If you are
unsure of the suitability of this equipment for your
installation, consult Rotork Process Controls prior
to proceeding.

WARNING - SHOCK HAZARD

WARNING - ELECTROSTATIC DISCHARGE

This electronic control is static-sensitive. To protect
the internal components from damage, never
touch the printed circuit cards without using
electrostatic discharge (ESD) control procedures.

RECEIVING/INSPECTION

Carefully inspect for shipping damage. Damage to the
shipping carton is usually a good indication that it has
received rough handling. Report all damage immedi­ately to the freight carrier and Rotork Process Controls,
Inc.

Unpack the product and information packet—taking
care to save the shipping carton and any packing
material should return be necessary. Verify that the
items on the packing list or bill of lading agree with
your own.

STORAGE

If the product will not be installed immediately, it
should be stored in a clean, dry area where the ambi­ent temperature is -13° to 131° F (-25 to 55° C). The
actuator should be stored in a non-corrosive environ­ment. The actuator is not sealed to NEMA 4 until the
conduit entries are properly connected.

EQUIPMENT RETURN

A Returned Goods authorization (RG) number is

required to return any equipment for repair. This must
be obtained from Rotork Process Controls. (Telephone:
414/461-9200) The equipment must be shipped,
freight prepaid, to the following address after the RG
number is issued:

Rotork Process Controls, Inc.
5607 West Douglas Avenue
Milwaukee, Wisconsin 53218
Attn: Service Department

To facilitate quick return and handling of your equip­ment, include:

1. RG Number on outside of box

2. Your Company Name, Contact Name, Phone/Fax

3. Address

4. Repair Purchase Order Number

5. Brief description of the problem

Installation and servicing must be performed only
by qualified personnel.

GENERAL ACTUATOR DESCRIPTION

The GPSA is a high precision linear actuator. It is
capable of producing 200 pounds of force over its 1.38
inch stroke length at a speed of up to .13 inches per
second. At a speed of .25 inches per second the unit is
capable of producing 100 pounds of thrust.

It can utilize up to three input signals, independently
configurable as either current (4-20 ma) or voltage
(1-5 V) for control. Two dry contact inputs are
available and may be configured to energize or de­energize on fault. The actuator provides three output
relays which are configurable as to their trigger and to
act as NO or NC. A position feedback signal is pro­vided via a 4-20ma transmitter, which is configurable
as either internally powered or externally loop
powered.

A two line, 16 character VFD display and rotary
switches comprise the actuators HMI. This provides
access for viewing and modifying changeable
parameters and data feedback.
