1. Introduction

1.1 General Information for the users

Each product has been fully inspected after its production to offer you the highest quality and reliable

performance. Please read the product manual carefully prior to installing and commission the

product.

Installation, commissioning, and maintenance of the product may only be performed by trained

specialist personnel who have been authorized by the plant operator accordingly.

The manual should be provided to the end-user.

The manual can be altered or revised without any prior notice. Any changes in product’s

specification, design, and/or any components may not be printed immediately but until the

following revision of the manual.

When the manual refers to “Valve Zero / Zero” means the final valve position upon pneumatic

pressure has been fully exhausted from positioner’s OUT1 port. For example, the valve zero

position may differ between linear direct and reverse actions. (DA/RA).

In case of any other problems that are not stated in this manual, please make immediate contact

to OMC Spa.

Positioner is an accessory of the control valve, so please make sure to read the applicable

instruction manual of the control valve prior to installation and operation.

1.2 Manufacturer Warranty

For the safety, it is important to follow the instructions in the manual. Manufacturer will not be

responsible for any damages caused by user’s negligence.

Any modifications or repairs to the product may only be performed if expressed in this manual.

Injuries and physical damages caused by customer’s modifying or repairing the product without

a prior consultation with OMC Spa will not be compensated. If any alterations or modifications

are necessary, please contact OMC Spa directly.

The warranty period of the product is (18) months from the date of shipment unless stated

otherwise. Date of shipment can be checked by providing the LOT NO. or SERIAL NO. to us.

Manufacturer warranty will not cover products that have been subjected to abuse, accidents,

alterations, modifications, tampering, negligence, misuse, faulty installation, lack of reasonable

care, repair or service in any way that is not contemplated in the documentation for the product,

or if the model or serial number has been altered, tampered with, defaced or removed; damages

that occurs in shipment, due to act of God, failure due to power surge, or cosmetic damage.

Improper or incorrectly performed maintenance will void this limited warranty.

2. Product Description

2.1 General

RE20 Smart Valve Positioner accurately controls valve stroke in response to an input signal of

4~20mA from the controller. Built-in micro-processor optimizes the positioner’s performance and

provides unique functions such as Auto-Calibration, PID Control.

2.2 Main Features and Functions

LCD display enables users to monitor the positioner status.

User will easily understand the method of using 4 buttons because it work same in all versions of

firmware interfaces.

When unexpected situation like momentary blackout happens, our positioner boot-time only take

0.5 second and this can minimize the travel of valve which consequentially increase the safety of

system.

Positioner operates normally even there are sudden changes in supply pressure and / or high

vibration environment.

The method of Auto Calibration is very simple.

As an advantage of having very low air consumption, It could greatly reduce operating costs in

large-scale plants.

It is compatible with most of controllers.

Orifices can be installed even in the field to minimize the hunting occurrence and optimize

operating conditions.

Valve system becomes more stable by outputting analog feedback signal.

Different valve characteristics can be adjusted – Linear, Quick Open, Equal Percentage, and

User Set which user can make 5 or 21 points characterizations.

Tight Shut – Close and Shut - Open can be set.

PID parameters can be adjusted in the field without any additional communicator.

Split range 4~12mA or 12~20mA can be set.

Operating temperature for positioners is -30 ~ 85℃(Please check certified explosion proof

temperature in case of Ambient temperature)

Hand calibration function can set Zero point or End point manually.

It has IP66 protection grade.

Polyester powder coating resists the corrosion process.

Maintenance of the positioner is easy because of modularized inner structure.
