The intended use of the compact pressure switch is to measure, monitor
and display pressure and provide an output signal.
1 Safety Instructions
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 (ISO/IEC)
*1)
, and other safety regulations.
*1)
ISO 4414: Pneumatic fluid power - General rules relating to systems.
ISO 4413: Hydraulic fluid power - General rules relating to systems.
IEC 60204-1: Safety of machinery - Electrical equipment of machines.
(Part 1: General requirements)
ISO 10218-1: Robots and robotic devices - Safety requirements for
industrial robots - Part 1: Robots.
•
Refer to product catalogue, Operation Manual and Handling
Precautions for SMC Products for additional information.
•
Keep this manual in a safe place for future reference.
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
•
Always ensure compliance with relevant safety laws and
standards.
•
All work must be carried out in a safe manner by a qualified person in
compliance with applicable national regulations.
•
This product is class A equipment intended for use in an industrial
environment. There may be potential difficulties in ensuring
electromagnetic compatibility in other environments due to conducted
or radiated disturbances.
•
Refer to the operation manual or catalogue on the SMC website (URL:
) for more safety instructions.
2 Specifications
2.1 General specifications
*1: When vacuum is used, there is no influence on the switch even if 0.5
MPa of pressure is supplied instantaneously.
*2: Window comparator mode: Since the hysteresis is 3 digits, P1 should
be separated from P2 by 7 digits or more.
1 digit is the minimum pressure display unit.
*3: Only for the pressure switch with analogue output selected.
*4: In case of ZSE3-#-23 or 24, failure predictive output: Red.

the ON/OFF set value.
4 Installation
4.1 Installation
Warning
Do not install the product unless the safety instructions have been read
and understood.
4.2 Environment
Warning
•
Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
•
Do not use in an explosive atmosphere.
•
Do not expose to direct sunlight. Use a suitable protective cover.
•
Do not install in a location subject to vibration or impact. Check the
product specifications.
•
Do not mount in a location exposed to radiant heat.
4 Installation (continued)
4.3 Piping
Caution
•
Before connecting piping make sure to clean up chips, cutting oil, dust
etc.
•
When installing piping or fittings, ensure sealant material does not
enter inside the port. When using seal tape, leave 1 thread
exposed
on the end of the pipe/fitting.
•
Connect the digital pressure switch to the piping with a hexagon socket
head plug and a fitting.
•
The tightening torque for the piping port must be 8.8 N•m maximum.
4.4 Lubrication
Caution
•
SMC products have been lubricated for life at manufacture, and do not
require lubrication in service.
•
If a lubricant is used in the system, use turbine oil Class 1 (no additive),
ISO VG32. Once lubricant is used in the system, lubrication must be
continued because the original lubricant applied during manufacturing
will be washed away.
5 Wiring
5.1 Wiring connections
•
Connections should be made with the power supply turned OFF.
•
Use a separate route for the product wiring and any power or high
voltage wiring. Otherwise, malfunction may result due to noise.
•
If a commercially available switching power supply is used, be sure to
ground the frame ground (FG) terminal. If the switching power supply
is connected for use, switching noise will be superimposed and it will
not be able to meet the product specifications. In that case, insert a
noise filter such as a line noise filter/ferrite between the switching
power supplies or change the switching power supply to a series power
supply.
•
Incorrect wiring will lead to digital pressure switch damage, failure or
malfunction. Be sure to confirm the wire colour and terminal number
before wiring.
5.2 Connector attaching / detaching
•
When assembling the connector, push it straight onto the pins until the
lever locks into the housing.
•
To remove the connector, push the lever down to unlock the hook from
the groove, and withdraw the connector straight out.
