INTRODUCTION

This installation and operating manual explains how to install, operate and maintain REA60 electric actuators.

Safety notices in this manual detail precautions the user must take to reduce the risk of personal injury and

damage to the equipment. User must read these instructions before installation, operating, or maintenance.

DANGER: Refers to personal safety. Alerts the user to potential danger or harm. The hazard or unsafe

practice will result in severe injury or death.

WARNING: Refers to personal safety. Alerts the user to potential danger. Failure to follow warning

notices could result in personal injury or death.

CAUTION: Directs the user’s attention to general precautions that, if not followed could result in personal injury

and/or equipment damage.

PRODUCT IDENTIFICATION

The actuator name plate is located on the top cover of the actuator.

The name plate contains the following:

TORK logo (trade mark)

Electrical power supply

Model

Type

Rated current

Operating time (seconds)

Serial No.

Option

Initial Inspection

Upon receipt of the actuator, inspect the condition of the product and ensure the name plate matches the order

sheet or your requirements, also check for any damage that may have occurred during shipment. If the wrong

product has been shipped immediately or is damaged report to the coordinator.

Storage

Actuators must be stored in a clean, cool and dry area. The unit shall be stored with the cover fastened and the

conduit openings sealed. Storage must be off the floor, covered with a seal dust protector.

When actuators are stored outdoors, they must be stored off the ground, high enough to prevent being immersed

in water or buried in snow.

GENERAL INFORMATION AND FEATURES

REA series electric actuators are designed to provide reliable and efficient operation of 90 degree quarter turn

valves , dampers, etc.

Duty Cycle

Duty cycle is rated IEC60034 - S4 50% / S2 30 min

Exceeding the actuators rated duty cycle may cause thermal overload.

Type of duty according to VDE 0530 / IEC 60034-1

Short - time duty S2

The operation time at a constant load is short, so that ther-mal equilibrium is not reached. The pause is

long enough for the machine to cool down to ambient temperature. The duration of the short - time

operation is limited to 15 min (10 min, 30 min).

Intermittent duty S4

The duty is a sequence of identical cycles which consist of starting time, operation time with constant load

and rest period. The rest period allows the machine to cool down so that so that thermal equilibrium is not

reached. The relative on-time at S4-25% or S4-50% is limited to 25% and 50% respectively .

Heater

Condensation in the actuator is possible due to wide fluctuation of the ambient temperature. The heater integrated

in the control unit prevents this in general.

Manual Hand Wheel and Lever

REA actuators are provided with a manual operation system.

The REA60 actuator comes standard with a manual override nut.

This is located on the bottom of the unit, and can be easily operated with a 5M wrench.

Turn the hand wheel until the valve reaches the required position.

Turn clockwise to open and counter clockwise to close.

When nut becomes tight DO NOT FORCE further as this will cause serious damage to the gearing.

Note: The override engagement lever returns automatically to auto position when the actuator is operated

electrically.

Lubrication

REA is a totally enclosed unit with a permanently lubricated gear train (Moly EP Grease). Once installed lubrication

should not be required. However, periodic preventative maintenance will extend the operating life of the actuator.

INSTALLATION INSTRUCTION

Pre-Installation (for use in General Services)

Verify the actuators name plate to ensure correct model number, force, operating speed, voltage and enclosure

type before installation and use.

It is important to verify that the output force of the actuator is appropriate for the force requirements of the valve

and that the actuator duty cycle is appropriate for the intended application.

WARNING: Read this installation and maintenance manual carefully and completely before attempting to

install, operate or trouble shoot the REA actuators.

Actuator Mounting

Note:

Prior to mounting the part-turn actuator it must be checked for damage.

Damaged parts must be replaced by original spare parts.

Mounting is most effectively carried out with the valve shafting pointing vertically upwards, however mounting is

also possible in any other position.

The REA series actuators are supplied with a Union Joint and nut which is removable for ease of machining.

CAUTION:

Do not attempt to work on your REA actuator without first shutting off Incoming power.

Do not attach ropes or hooks to the hand wheel for the purpose of lifting by hoist.
