SMC Networks ZSE30A series,ISE30A Series,ZSE30AF series Operation Manual

Pressure Setting

Set ON and OFF point of the Pressure switch.

Operation

When the pressure exceeds the set value, the
Pressure switch will turn ON.
When the pressure falls below the set value by
the amount of hysteresis or more, the
Pressure switch will turn OFF.
The default setting of the output set
value is the central value between the
atmospheric pressure and the upper
limit of the rated pressure range.
If this condition, shown to the
right, is acceptable, then keep
these settings.

<How to operate>

[Hysteresis mode]

1. Press the button once in measurement mode.

2. [P_1] or [n_1] and the set value are
displayed in turn.

serious injury.

DANGER indicates a hazard with a high level of risk
which, if not avoided, will result in death or serious
injury.

Safety Instructions

Do not disassemble, modify (including changing the printed circuit board) or repair.

An injury or failure can result.

Do not operate in an atmosphere containing flammable or explosive gases.

Fire or an explosion can result.
This product is not designed to be explosion proof.

Do not use the product in a place where static electricity is a problem.

Otherwise it can cause failure or malfunction of the system.

NOTE

•The direct current power supply to be used should be UL approved as follows:
Circuit (of Class2) which is of maximum 30 Vrms (42.4 V peak), with UL1310

•Provide a double interlocking system, for example a mechanical system

•Check the product regularly for proper operation

Otherwise malfunction can result, causing an accident.

The following instructions must be followed during maintenance:

•Turn off the power supply

•Stop the air supply, exhaust the residual pressure and verify that the air is released before performing
maintenance work

Otherwise an injury can result.

After maintenance is complete, perform appropriate functional inspections and leak tests.

Stop operation if the equipment does not function properly or there is a leakage of fluid.
When leakage occurs from parts other than the piping, the product might be faulty.
Disconnect the power supply and stop the fluid supply.
Do not apply fluid under leaking conditions.
Safety cannot be assured in the case of unexpected malfunction.

Do not touch the terminals and connectors while the power is on.

Otherwise electric shock, malfunction or damage to the product can result.

o not operate the product outside of the specifications.

Do not use for flammable or harmful fluids.
Fire, malfunction, or damage to the product can result.
Verify the specifications before use.

The Pressure switch operates within a set pressure range (from P1L to P1H)
during window comparator mode. Set P1L (switch lower limit) and P1H (switch
upper limit) with the setting procedure above. (When reversed output is
selected, [n1L] and [n1H] are displayed.)

Zero clear of display

The display is reset to zero when the and buttons are pressed
simultaneously for 1 second.
For the initial operation, always perform zero clear with no pressure applied.

Maintenance

How to reset the product after a power cut or forcible de-energizing

The setting of the product will be retained as it was before a power cut or
de-energizing.
The output condition is also basically recovered to that before a power cut or
de-energizing, but may change depending on the operating environment.
Therefore, check the safety of the whole installation before operating the product. If
the installation is using accurate control, wait until the product has warmed up
(approximately 10 to 15 minutes).

Troubleshooting

The switch output load current is more
than 80 mA.

T

urn the power off and remove the
cause of the over current. Then
turn the power on.

Error Indication

This function is to display error location and content when a problem or an error
occurs.

System Error

During the zero clear operation,
pressure above ±7%F.S. (±3.5%F.S.
for compound pressure) has been
applied. After 1 second, the mode will
return to measurement mode. The zero
clear range can vary ±1%F.S. with
individual product differences.

Perform zero clear operation again
after restoring the applied pressure
to an atmospheric pressure
condition.

Pressure has exceeded the upper limit
of the set pressure range.

Displayed in the case of an internal
data error.

Reset applied pressure to a level
within the set pressure range.

Turn the power off and turn it on
again.
If resetting fails, an investigation by
SMC Corporation will be required.

If the error can not be reset after the above measures are taken, then please
contact SMC.

Note: Specifications are subject to change without prior notice and any obligation on the part of the manufacturer.

Piping

Connection using One-touch fitting

1. Cut the tube end perpendicular.

2. Hold the tube and insert it into the
One-touch fitting slowly until it
bottoms out.

Allow sufficient tube length to prevent
twist and tensile or moment loads from
being applied to the fitting or tube.
When using a tube manufactured by a company other than
SMC, check that its outside diameter tolerance satisfies the following values:

1) Nylon tube: ±0.1 mm maximum

2) Soft nylon tube: ±0.1 mm maximum

3) Polyurethane tube: +0.15 mm/-0.2 mm maximum

Wiring

Connection

Connections should only be made with the power supply turned off.
Use separate routes for the Pressure switch wiring and any power or high
voltage wiring. Otherwise, malfunction may result due to noise.
Ensure that the FG terminal is connected to ground when using a
commercially available switch-mode power supply. When a switch-mode
power supply is connected to the product, switching noise will be
superimposed and the product specification can no longer be met. This can
be prevented by inserting a noise filter, such as a line noise filter and ferrite
core, between the switch-mode power supply and the product, or by using a
series power supply instead of the switch-mode power supply.

Mounting with panel mount adapter

Fix the panel mount adapter to the product with the mounting screws
(nominal seiz: 3 x 8 L, 2 pcs.) supplied.
