SS2L / SS2R Series
1. Introduction
1.1 General Information
This instruction and operating manual contains important notices the user should observe for a personal
safety as well as for prevention against damage to property. Notices concerning a personal safety are
highlighted by a safety alert symbol (

).

1.2 General Safety Instructions
This product was delivered out from the factory without any safety problems after a strict quality
management process. In order to maintain this status and ensure a safe operation of this product,
please be sure to read all safety instructions carefully described in this manual and observe safety
information and symbols without exception.
1.3 Correct Usage
①


This product can be used only for purposes specified in these instructions. If they are not
definitely stated in these instructions, the user is fully responsible for all changes and retrofits to
this product.

②

In case of the intrinsically safe product supplied, please make sure to connect this product to the
certified intrinsically safe circuits. These circuits should correspond with the intrinsic safety
parameters indicated on the product nameplate or the certificates. If the circuits do not
correspond with the intrinsic safety parameters on the product nameplate or the certificates, any
safety required for approval can no longer be warranted.

③

This product is the electrostatic sensitive device that may be seriously damaged by voltages
undetectable to a human. These kinds of voltages occur as soon as a electronic component or
an assembly is touched by a person who is not grounded against a static electricity. Damage to a
electronic component as a result of overvoltage cannot usually be detected immediately. It may
become apparent after a long period of operation. Therefore, please make sure to avoid
electrostatic charge.

1.4 Range and Responsibilities of Personnel
①

Qualified personnel should be trained, instructed or authorized in operating and maintaining
products and systems according to the safety regulations for electrical circuits, high pressures
and hazardous atmosphere.

②


For explosion proof products, they should be trained, instructed or authorized in carrying out
work on electrical circuits for hazardous systems.

③

They should be trained or instructed in maintenance and use of proper safety equipment
according to the safety instructions.

④

They should have a good experience to identify risks and avoid potential hazards when working
with these products and systems.

1.5 Transport and Storage
Make sure that damages during delivery are prevented through proper packaging.
Products and replacement parts should be returned in their original packaging. If the original packaging
is no longer available, please ensure that they should be packaged to provide sufficient protection
against transport.

5. Principle of Operation

If 4-20 mA input signal is supplied, the micro processor compares input signal with position feedback
and sends control signal to the I/P converting module. Pneumatic signal from the I/P converting module
operates the valve and the valve stays at the desired position.

7.1.7 Standard Installation

①

Supply air directly to the actuator, adjust the air filter regulator and set air when the valve
reaches to 50% stroke.

②

Install the feedback lever horizontally at 50% stroke position.

③

If the feedback lever is not installed horizontally, move the mounting bracket up and down little
by little so that it can be positioned horizontally.

④

Fix the mounting bracket with screws.

⑤

Connect air lines between the position and the actuator.


⑥

Supply air to the positioned and perform auto-calibration by pushing Mode button for 5
seconds.

⑦

The operating angle from 0% to 100% stroke should be within the range of 30°. In case of the
over-range of 30°, move the valve stem pin left and right and make the operating angle stay
within 30°.
① Be sure to install the air filter regulator

before the positioned
