5 MAINTENANCEan

WARNING:

� Not following proper procedures could cause the product to malfunction and couldlead to damage to the equipment or machine.

� If handled improperly, compressed air can be dangerous. Assembly, handling andrepair of pneumatic system should be performed by qualified personnel only.

� Drain: remove condensate from the filter bowl on a regular basis.

� Shutdown before maintenance: before attempting any kind of maintenance makesure the supply pressure is shut off and all residual air pressure is released fromthe system to be worked on.

� Start-up after maintenance: apply operating pressure and power to the equipmentand check for proper operation and possible air leaks. If operation is abnormal,please verify product set-up parameters.

� Do not make any modification to the product

� Do not disassemble the product, unless required by installation or maintenanceinstructions.

� When equipment is removed, first confirm that measures are in place to preventdropping of work pieces and run-away of equipment, etc. Then cut the supplypressure and power, and exhaust all compressed air from the system using itsresidual pressure release function. Furthermore, with a 3 position closed center

type, release the compressed air that remains between the valve and cylinder inthe same manner. When the equipment is to be started again after remounting orreplacement, first confirm that measures are in place to prevent lurching ofactuators, etc., and then confirm that the equipment is operating normally.

� Valves should be switched at least once every 30 days to prevent malfunction. (Usecaution regarding the air supply.)

� When the manual override is operated, connected equipment will be actuated.Confirm safety before operating.

Replacing Cylinder Port FittingsCylinder port fittings are available in cassette type and can be replaced easily.Fittings are secured with a clip that is inserted from the topside of the valve. Removethe clip with a flat head screw driver, etc., to replace the fittings.To mount a fitting, insert the fitting assembly until it stops and reinsert the clip to itsdesignated position.

*Part numbers above are for one fitting; however, order them in 10 piece units.

<Caution>Do not scratch or put foreign matter on the O-rings as this will cause air leakage.

Build-in Silencer ElementsA filter element is built into the manifold base end plate. When the element becomesdirty and clogged, this will cause trouble such as a drop in the cylinder speed, etc.Therefore, replace the element regularly.

To replace an element, remove the cover on the topside of the end plate and removethe old element with a flat head screwdriver, etc.

6 LIMITATIONS OF USE

WARNING:

� Do not exceed any of the specifications laid out in section 2 of this document or thespecific product catalogue.

Operating Environment

1. Do not use valves in atmospheres of corrosive gases, chemicals, salt water, water orsteam, or where there is direct contact with them.

2. Do not use in an explosive atmosphere.3. Do not use in locations subject to vibration or impact. Confirm the specifications in

the main section of the catalog.4. A protective cover, etc., should be used to shield valves from direct sunlight.5. Shield valves from radiated heat generated by nearby heat sources.6. Employ suitable protective measures in locations where there is contact with water

droplets, oil or welding spatter, etc.7. When solenoid valves are mounted inside a control panel or are energized for

extended periods of time, employ measures to radiate excess heat so thattemperatures remain within the valve specification range.

Extended periods of continuous energization

Use the low power consumption specification (0.5W) if valves will be continuouslyenergized for extended periods of time or the energized period will be longer than thede-energized period. Use the low power consumption specification (0.5W) especiallywhen three or more adjacent stations on a manifold are continuously energized,because the temperature increases substantially. For 2 position double latching type,use the type with energy saving circuit SQ 2 - __-X11.

Momentary energization (double solenoid type)

If a double solenoid valve will be operated with momentary energization, it should beenergized for at least 0.1 second (20mS or more for 2 position double latching type).However, malfunction may occur due to load conditions on the secondary side. In thatcase energize until the cylinder moves to the stroke end. Furthermore, when using adouble solenoid valve for air blowing, energize when performing the air blowing.

Leakage voltage

Particularly when using a C-R element (surge voltage suppressor) for protection of theswitching element, take note that leakage voltage will increase due to leakage currentflowing through the C-R element, etc

Limit the amount of residual leakage voltage to the following values:

2% or less of rated voltage

Operation of solenoid valves with an SSR

Malfunction may occur when the minimum load current of the SSR is larger than theload current of solenoid valves. Consider the element specifications in the catalog toselect an SSR.

Surge voltage suppressorIf a general diode such as zener diode or ZNR is not used in the surge voltagesuppressor on the controller side, be aware that there will be a residual voltageaccording to the protective element and rated voltage. Moreover, the residual voltageof the diode is approximately 1V.

Low temperature operationValves can be operated at a temperature as low as -10°C unless otherwise indicated inthe specifications for each valve, however, measures should be taken to avoidsolidification or freezing of drainage and moisture, etc.

Operation for air blowingWhen using solenoid valves for air blowing, use an external pilot type. When using aninternal pilot and an external pilot on the same manifold, a pressure drop caused byair blowing may affect the internal pilot valve. Also, supply to the external pilot portcompressed air within the pressure range prescribed in the specifications; and with 2position double (double solenoid), always energize when air blowing.

Mounting orientationIn the case of 2 position single or 4 position dual 3 port valves, the mountingorientation is unrestricted. In the case of 2 position double (double solenoid) or 3position valves, mount so that the spool valve is horizontal.
