SMC Networks 56-EX500-S001, 56-EX500-S101, 56-EX500-Q001, 56-EX500-Q101 Installation & Maintenance Manual

Design and selection

Operate the unit only within the specified supply voltage limits.

If the supply voltage exceeds the rated voltage limits the unit and
connected equipment might malfunction or could be damaged. It could
also become a fire hazard.

Do not operate beyond specification range.

Fire, malfunction or unit and connected equipment damage can result.

Please construct a backup system, such as making the
equipment or unit a multiple system, or designing a fail-safe in
advance to prevent damage due to the breakdown and the
malfunction of this product.
Mount the emergency stop outside of the enclosure so that it can
stop the system operation immediately and intercept the power
supply.
These instructions must be followed when using the Gateway
unit in an interlocking circuit:

•Provide valve interlocking by another system such as

mechanical protection.

•Check the Gateway unit regularly to ensure mechanical

protection.
There is a risk of getting injured if the interlock does not operate
correctly.

Wiring

Perform wiring correctly.

There is a possibility that a unit and connected equipment will be
destroyed if incorrectly wired.

Do not perform wiring while power is on.

If there is an explosive atmosphere present there is a risk of an
explosion.
There is also a possibility of failure of operation due to the damage of a
unit and connected equipment.

Do not lay wires or cables with power cable or high-voltage
cable in the same wiring route.

There is a possibility of failure of operation due to electrical noise on
the signal cable or a surge in the power cable. Separate the wiring of
reduced wiring system from power cables.

Confirm proper insulation of wiring.

With insulation failure (contact with other circuits, insulation failure
between terminals, etc), there is a risk of explosion if an explosive
atmosphere is present. There is also a possibility of damage to a unit
and connected equipment due to the applied excess pressure or current.

Operating environment

Do not use in an environment where water, chemicals, or oil
are present. Prevent dust and particles collecting on or around
the unit.

It will cause failure or malfunction.

Do not use in an area where a magnetic field is generated.

It will cause malfunction.

Do not connect or disconnect cables when the unit is powered.

Fire or an explosion may result if an explosive or combustible gas is
present.

Do not use in an environment with temperature cycle.

Heat cycles other than that of daily change of the temperature can effect
inside of the units.

Do not expose the wiring system to heat radiation from a heat
source located nearby.

It will cause failure or malfunction.

Do not use in an environment where a surge source more than
the CE marking standard allow is present.

Internal circuit elements can deteriorate or break when equipment
generating a large surge (electromagnetic lifter, high frequency induction
furnace, motor, etc.) is located near the wiring system. Provide surge
preventives, and avoid interface.

Use the wiring system equipment with surge absorber when a
surge-generating load such as relay or solenoid valve is driven
directly.
Do not expose the wiring system to vibration and impact.

It will cause failure or malfunction.

Adjustment and Operation

Do not allow short circuit of loads.

Connected equipment may be damaged by excess current flow if a load is
short circuit. Input unit fuse will break. Output and SI unit have protective
function for excess current flow, but it is possible that they will be damaged,
as the protective function does not cover all modes.

The SI unit should be used within the range of specifications given
below and in the product catalogue.

If labelled with X: special conditions apply:

1. Protect the SI unit from sources of heat which can generate surface
temperatures higher than the ATEX temperature classification.

2. Protect the SI unit and cables against all impact or mechanical
damage using a suitable ATEX compliant enclosure.

3. Protect the SI unit from direct sunlight or UV light using a suitable
protective cover.

4. Do not disconnect the M12 connectors before first switching off the
power supply.

5. Use only ATEX approved M12 connectors and use only shielded
cable to provide grounding.

6. Use only a damp cloth to clean the SI unit body, to avoid an
electrostatic charge.

Mounting

Do not drop, bump or apply excessive impacts
while handling.

Otherwise it can result in damage to the SI unit causing
failure or malfunction.

Hold the body for handling.

Otherwise it can result in damage to the SI unit causing
failure or malfunction.

Mount units using the proper tightening torque.

If a unit is tightened beyond the range of tightening torque,
the mounting screws, mounting brackets or unit may be
damaged

Do not mount the unit where it may be stepped on.
If the unit is stepped on it will be damaged.

Wiring

Avoid repeatedly bending or stretching the lead
wires.

Do not crush or strain the wire. It will cause the wire to
break and make the unit malfunction

Ground the reduced wiring system to a secure,
safe and noise-proof place

Grounding should be performed near the unit to shorten the
grounding distance.

Maintenance

Only clean the product with a damp cloth.

Do not wipe the product with chemicals such as benzene or
thinners. It will cause damage to the product.

Installation & Maintenance Manual

SI Unit

Series 56-EX500-S001/S101

Read this manual before using this product.

For future reference, please keep this manual in a safe place.

This manual should be read in conjunction with the current catalogue.

General recommendation

These safety instructions are intended to prevent a hazardous
situation and/or equipment damage.
These instructions indicate the level of potential hazard by label of
"Caution", "Warning" or "Danger".

Operator error could result in injury or
equipment damage.

Operator error could result in serious injury
or loss of life.

In extreme conditions, there is a possible
result of serious injury or loss of life.

• A system designer or a person who decides a system

specification should judge the compatibility of a reduced
wiring system.

Since the products specified here are used in various operating
conditions,their compatibility for the specific

wire saving

system
must be based on specifications or after analysis and/or tests to
meet your specific requirements.

•

Only trained personnel should operate pneumatically operated

machinery and equipment.

Compressed air can be dangerous if an operator is unfamiliar with it
Assembly, handling or repair of wire savingsystems should be
performed by trained and experienced operators.

•

Do not service machinery/equipment or attempt to remove

component until safety is confirmed.

1) Inspection and maintenance of machinery/equipment should only be
performed after confirmation of safe locked-out control positions.

2) When equipment is to be removed, confirm the safety process as
mentioned above. Switch off air and electrical supplies.

3) Before machinery/equipment is re-started, ensure all safety measures to
prevent sudden movement of actuators etc. (Supply air into the system
gradually to create backpressure, i.e. incorporate a soft-start valve).

•

Contact SMC if the product is to be used in any of the following

conditions:

1) Conditions and environments beyond the given specifications, or if
product is used outdoors.

2) Installations in conjunction with atomic energy, medical equipment, food
and beverage, or safety equipment.

3) Applications which have the possibility of having negative effects on
people, property or animals.
Special safety analysis is required.

Do not carry out operation or setting of this equipment with wet
hands.

It may cause an electric shock to the operator.

Maintenance

Do not disassemble, modify (including change of printed circuit
board) or repair.

An injury or failure can result.

Perform the following maintenance periodically in order to prevent
possible danger due to the unexpected.

Confirm wiring and screws are not loose.
Loose screws or wires may cause unintentional malfunction.

These instructions must be followed while in maintenance:

•

Turn off the power supply.

•

Stop the supplied fluid, exhaust the residual pressure and verify

the

release of fluid before performing maintenance.

Otherwise it can cause injury.
