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.

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 tothe 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.
Mating connector wiring details:
Wire size: 0.2 to 0.33 mm2max.
Wire sheath diameter 1.7 mm max.

6 Pressure Setting
6.1 2 output type
6.2 Output method
•Hysteresis mode (P1≥P2, P3≥P4)
•Window comparator mode (P1＜P2, P3＜P4)
•Hysteresis mode (same as for positive pressure use) When the value
of hysteresis is set to 2 digits or less, the switching output might chatter
due to fluctuation of the input pressure around its set point.
•Window comparator mode (same as for positive pressure use) since
the hysteresis will be 3 digits, separate P1 from P2 (in case of 2-output
type, same as for P3 and P4) by 7 digits or more.
* 1 digit is the minimum pressure display unit.
6 Pressure Setting (continued)
6.3 1 Output type with Failure Predictive function
6.4 Failure Predictive function
The failure predictive detection counter is incremented when the switch
is turned on then is turned off, without the pressure (exceeding P1) not
reaching the failure predictive pressure (P3).
The failure predictive detection output is energized when the set failure
predictive counter (EC) is incremented consecutively. When the switch is
turned ON and the pressure (exceeding P1) exceeds the failure
predictive pressure (P3), the failure predictive counter is reset.
(This example shows a case in the hysteresis mode).

•Peak Hold mode
•Bottom Hold mode

8 Error Indication
Error Display Error Type Troubleshooting Method
The set data has
been changed
under some
influences.
Press the RESET button
and set all data again.
Load of OUT1 has
short-circuited and
overcurrent is
flowing.
Turn off the power supply
and replace the load
connected to the OUT1
(black wire).
Load of OUT2 has
short-circuited and
overcurrent is
flowing.
Turn off the power supply
and replace the load
connected to the OUT2
(white wire).
Pressure exceeding
0.5 MPa has been
applied.
(In case of positive
pressure, pressure
exceeding the rated
pressure has been
applied.)
Lower the pressure to 0.5
MPa or less. (In case of
positive pressure, lower
the pressure to the rated
pressure or less.)
Compared with the
ambient pressure
-0.07 MPa (in case
of 1 MPa use) or -7
kPa or more (in
case of vacuum use
or 100 kPa use) has
been applied during
zero clear.
After adjusting the
pressure to the ambient
pressure, perform RESET
operation.
If the error cannot be reset after the above measures are taken, then
please contact SMC.

to malfunction and lead to equipment damage.
•If handled improperly, compressed air can be dangerous.
•Maintenance of pneumatic systems should be performed only by
qualified personnel.
•Before performing maintenance, turn off the power supply and be sure
to cut off the supply pressure. Confirm that the air is released to
atmosphere.
•After installation and maintenance, apply operating pressure and
power to the equipment and perform appropriate functional and
leakage tests to make sure the equipment is installed correctly.
•If any electrical connections are disturbed during maintenance, ensure
they are reconnected correctly and safety checks are carried out as
required to ensure continued compliance with applicable national
regulations.
•Do not make any modification to the product.
•Do not disassemble the product, unless required by installation or
maintenance instructions.
How to reset the product after power cut or forcible de-energizing
