Safety Instructions 1
These safety instructions are intended to prevent hazardous situations and/or equipment damage.
These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or
“Danger.” They are all important notes for safety and must be followed in addition to International
Standards (IEC)Note 1), and other safety regulations.
Note 1) IEC 60079-0 : 2007 EN 60079-0 : 2009
IEC 60079-1 : 2007 EN 60079-1 : 2007
Caution
Caution indicates a hazard with a low level of risk which, if not avoided, could result in
minor or moderate injury.
Warning
Warning indicates a hazard with a medium level of risk which, if not avoided, could
result in death or serious injury.
Danger
Danger indicates a hazard with a high level of risk which, if not avoided, will result in
death or serious injury.
Warning
1. The compatibility of the product is the responsibility of the person who designs the equipment or
decides its specifications.
Since the product specified here is used under various operating conditions, its compatibility with specific
equipment must be decided by the person who designs the equipment or decides its specifications based
on necessary analysis and test results. The expected performance and safety assurance of the equipment
will be the responsibility of the person who has determined its compatibility with the product. This person
should also continuously review all specifications of the product referring to its latest catalogue information,
with a view to giving due consideration to any possibility of equipment failure when configuring the
equipment.
2. Only personnel with appropriate training should operate machinery and equipment. The product
specified here may become unsafe if handled incorrectly.
The assembly, operation and maintenance of machines or equipment including our products must be
performed by an operator who is appropriately trained and experienced.
3. Do not service or attempt to remove product and machinery/equipment until safety is confirmed.
1. The inspection and maintenance of machinery/equipment should only be performed after measures to
prevent falling or runaway of the driven objects have been confirmed.
2. When the product is to be removed, confirm that the safety measures as mentioned above are
implemented and the power from any appropriate source is cut, and read and understand the specific
product precautions of all relevant products carefully.
3. Before machinery/equipment is restarted, take measures to prevent unexpected operation and
malfunction.
4. Contact POWER-GENEX beforehand and take special consideration of safety measures if the
product is to be used in any of the following conditions.
1. Conditions and environments outside of the given specifications, or use outdoors or in a place exposed to
direct sunlight.
2. Installation on equipment in conjunction with atomic energy, railways, air navigation, space, shipping,
vehicles, military, medical treatment, combustion and recreation, or equipment in contact with food and
beverages, emergency stop circuits, clutch and brake circuits in press applications, safety equipment or
other applications unsuitable for the standard specifications described in the product catalogue.
3. An application which could have negative effects on people, property, or animals requiring special safety
analysis.
4. Use in an interlock circuit, which requires the provision of double interlock for possible failure by using a
mechanical protective function, and periodical checks to confirm proper operation.
5. Do not open when an explosive gas and dust atmosphere may be present
6. To avoid the risks of electrostatic discharges, the user has to make sure of the absence of
dangerous atmosphere before cleaning the device, or will have to clean it only with a damp cloth or
antistatic products.

Precautions 1
Be sure to read before handling.
Handling
Caution
1. Avoid excessive vibration or impact to the positioner body and any excessive force to the
armature, as these actions may cause damage to the product. Handle carefully while
transporting and operating.
2. If being used in a place where vibration occurs, using a binding band is recommended to
prevent broken wires because of the vibration.
3. When exposed to possible moisture invasion, please take the necessary measures. For example,
if the positioner is left onsite for long periods, a plug should be put in the piping port and a body
cover unit fitted to avoid water penetration.
Take measures to avoid dew condensation inside the positioner if exposed to high temperature and
humidity. Take enough measures against condensation especially when packing for export.
4. Keep magnetic field off the positioner, as this affects its characteristics.
Air Supply
Caution
1. Use only dehumidified and dust extracted clean compressed air as the air supply.
2. Do not use compressed air containing chemicals, organic solvents, salinity or corrosive gases,
as this may cause malfunction.
3. When operating below the freezing point, protect the positioner from freezing.
Operating Environment
Caution
1. Do not operate in locations with an atmosphere of corrosive gases, chemicals, sea water, or
where these substances will adhere to the regulator.
2. Do not operate out of the indicated operation temperature range as this may cause damage to
electronic parts and seal materials to deteriorate.
3. Do not operate in locations where excessive vibration or impact occurs.

• 2 x SPDT • 2 x DPDT
① Be sure to supply the rated voltage and current stated on this manual. Otherwise, it may cause a
serious damage or malfunctions.
② Check polarity of + and – exactly and connect wires.
③ When it is necessary to open the positioner cover at a humid place, more attention is required. It may
cause a serious damage or malfunctions.
Explosion-proof construction
LSB-3 becomes explosion proof, as certified by IECEx/ATEX/KC, according to the model selected.
The explosion-proof grade has the following approval : Ex d IIC T*
Take extra care when handling the LSB-3 as explosion-proof equipment
To use as Ex d IIC T*
A) Pressure-proof packing.
As shown below in the chart, use "Cable gland"
B) Metal Piping.
Attach the sealant fitting bracket near the cable port.
(For details, refer to "The guideline on electric equipment explosion proof" published by the
Technology Institution of Industrial Safety).

- Setting
10.1 Earthing
The Postioner must be connected to a good quality earth. The units are provided with internal and
external earthing terminals which are both located on the terminal chamber section of the unit
① It is necessary to set Zero and Span of position transmitter manually.
② The power supply of 12 – 30VDC should be supplied.
- Install the LSB-7 properly before setting the position transmitter.
- Check the proper position of the RA/DA switch before setting.
1. Turn the Zero screw until the output signal reaches 4mA.
2. Turn the Span screw until the output signal reaches 20mA.
3. Repeat the above procedure until the output signals reach 4mA and 20mA.
4. Operate the valve and check if the output signals are transmitted properly.

9. Setting of Cams and Switches
a) Push up the red cam if it is necessary to set the position of the red cam.
b) Turn the red cam until it touches the limit switch. And put down and fix it with a wrench bolt.
c) Do the same procedure for setting of the blue cam. But push it down to move.
