Warning
1. The compatibility of the product is the responsibility of the person who designs the equipment or decides its specifications. Since the product specified here is used under various operating conditions, its compatibility with specific equipment must be decided by the person who designs the equipment or decides its specifications based on necessary analysis and test results. The expected performance and safety assurance of the equipment will be the responsibility of the person who has determined its compatibility with the product. This person should also continuously review all specifications of the product referring to its latest catalog information, with a view to giving due consideration to any possibility of equipment failure when configuring the equipment.
2. Only personnel with appropriate training should operate machinery and equipment. The product specified here may become unsafe if handled incorrectly. The assembly, operation and maintenance of machines or equipment including our products must be performed by an operator who is appropriately trained and experienced.
3. Do not service or attempt to remove product and machinery/equipment until safety is confirmed. 1.The inspection and maintenance of machinery/equipment should only be performed after measures to prevent falling or runaway of the driven objects have been confirmed. 2.When the product is to be removed, confirm that the safety measures as mentioned above are implemented and the power from any appropriate source is cut, and read and understand the specific product precautions of all relevant products carefully. 3. Before machinery/equipment is restarted, take measures to prevent unexpected operation and malfunction.
4. Contact SMC beforehand and take special consideration of safety measures if the product is to be used in any of the following conditions. 1. Conditions and environments outside of the given specifications, or use outdoors or in a place exposed to direct sunlight. 2. Installation on equipment in conjunction with atomic energy, railways, air navigation, space, shipping, vehicles, military, medical treatment, combustion and recreation, or equipment in contact with food and beverages, emergency stop circuits, clutch and brake circuits in press applications, safety equipment or other applications unsuitable for the standard specifications described in the product catalog. 3. An application which could have negative effects on people, property, or animals requiring special safety analysis. 4.

Handling precautions

! Caution

If the power supply to this product is turned off due to a power failure during operation, the output on the secondary side depends on the specifications.
Normal close specification: The output pressure is held.
Normal open Specification: Supply pressure minus 0.1 MPa or more pressure continues to flow out.

If supply pressure to this product is interrupted or shut off, while the power is still on, the internal solenoid valve will continue to operate and a humming noise will be generated. Since it may greatly affect the life of the built-in solenoid valve, when shutting off the supply pressure, turn off the power of this product or set the Solenoid Valve stop time.

This product is adjusted to specification at the time of shipment from the factory. Avoid careless disassembly or removal of parts, as this can lead to malfunction.
– 4 –

! Caution
Take the following steps to avoid malfunction due to noise. 1. Install a line filter etc. to the AC power line to
reduce / eliminate power supply noise. 2. Avoid malfunction due to noise by installing this
product and its wiring away from strong electric fields, such as those of motors and power cables, etc. 3. Be sure to implement protective measures against load surge for inductive loads (solenoid valves, relays etc.). 4. Turn off the power supply before inserting or removing the connector.
Please note that the right angled cable connector does not rotate and is limited to only one entry direction.

IO-Link Specifications
Outline of IO-Link functions Communication Function This product can check the pressure adjustment and diagnostic information using cyclic data communication via the IO-Link system. Product status monitoring function This function monitors the product status via the IO-Link communication. – Multiple errors (e.g. internal hardware errors) can be detected. – Multiple alarms can be detected (e.g., low pressure, over-voltage). – Multiple notifications can be detected (e.g., specified operation cycle of the solenoid valve has been reached). – Multiple notification states (reaching the set accumulated energizing time) can be detected. Output of fault status The output status (Hold/Clear) when a communication error occurs can be set. Data storage function The data storage function stores the IO-Link device parameter settings to the IO-Link master. With the IO-Link data storage function, the IO-link device can be replaced easily without re-setting the equipment construction or setting parameters. When the device parameters are set and downloaded to the device using the IO-Link setting tool, the parameters in the downloaded device will be activated. After that, these parameters are uploaded to the data storage in the master by stem command (back-up communication command). When the device is replaced with the same type of IO-Link device due to failure, the parameter settings stored in the master are download automatically, device can be operated with the parameter settings of the previous device. Three levels of back up can be set for each port of the master device (“Disabled,” “back-up/restore,” and “restore”). “Back-up” implies the activation of upload and “restore” implies download.

Sensitivity tuning function
Changing the sensitivity will change the pressure correction operation near the set pressure point. When the sensitivity is increased, hunting may occur. When the sensitivity is decreased, hunting will be reduced, but the pressure correction will be reduced, so there may be a moderate pressure instability.

Setting using buttons
! Caution
(1) If the incorrect key is pressed or incorrect information is displayed during setting, power must be shut off and the procedure started again.
(2) When you press the S key after completing the value setting for operation mode and standby mode, the operation will start immediately, so be careful when doing so. We recommend operation without supply pressure.
(3) Even if no signal is input, if pressure is supplied to the primary side, the pressure set in each mode will be output to the secondary side, so be careful. However, please note that for the NO type, when the power is turned off, the pressure equal to the supply pressure minus 0.1 MPa will be output.
(4) Output pressure from this product and state of operation are changed by changing of each setting and function. Each setting and function should be operated by trained and experienced operator.
(5) Do not configure settings using the button operation and IO-Link communication at the same time. If settings are made by both methods, unintended settings may be configured.

! Caution
The key lock function is preserved in the EEPROM (non-volatile memory). Its settings are reflected even after power cycling. (The key lock is deactivated by default at shipment). This setting interlocks with the key lock for the IO- Link parameter: Device access lock (Index 12) and can also be set via IO-Link. However, when buttons are operated, the button operations take priority and the settings via IO-Link are processed exclusively.

Maintenance
Before performing maintenance, turn off the power supply, stop the air supply, exhaust the residual
compressed air in the piping, and verify the release of air.
Foreign matter caught in the inlet or exhaust piping may interfere with operation. Periodic cleaning is necessary.
Do not use solvents such as benzene, thinner, etc., to clean the product including the switch cover. Use a soft dry cloth to remove stains.
