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) and other safety regulations. To obtain operating the ejector which is mounted on this product, please refer to “Handling Precautions for SMC Products” for vacuum equipment on our general product catalogue or precaution for each product.

• Caution: Operator error could result in injury or equipment damage.
• Warning: Operator error could result in serious injury or loss of life.
• Danger: In extreme conditions, there is a possibility of serious injury or loss of life.

Operator
This operation manual is intended for those who have knowledge of machinery using pneumatic equipment, and have sufficient knowledge of assembly, operation, and maintenance of such equipment. Only those persons are allowed to perform assembly, operation and maintenance. Read and understand this operation manual carefully before assembling, operating or providing maintenance to the product.

Warning

• Do not disassemble, modify (including changing the printed circuit board) or repair. An injury or failure can result.
• Do not use the product except for the energy-saving control ejector. Fire, malfunction, or damage to the product or the system can result.
• Do 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.
• 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.
• If using the product in an interlocking circuit:
  • 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. Otherwise an injury can result.
• Verify the system sufficiently before judging the applicability when a permeable workpiece is to be sucked. Rapid decrease in vacuum pressure during suction of the workpiece may cause the ejector to fail to restart in time, causing injury or damage to the system because of the suction failure.

Caution

• Do not touch the terminals and connectors while the power is on. Otherwise electric shock, malfunction or damage to the product can result.
• Perform sufficient trial run. Otherwise, injury or damage to the system can result due to suction failure depending on the conditions of the suction of the workpiece or the pressure switch settings. Perform sufficient verification before using this product.
• 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.

Installation

Wiring

Connection

• Connections should only be made with the power supply turned off.
• Use a separate route 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 the 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 a switch-mode power supply.

Connector

Connecting/Disconnecting

• When mounting the connector, insert it straight into the socket, holding the lever and connector body, and fit the hook of the lever into the groove in the housing to lock.
• When removing the connector, press down the lever to release the hook from the groove and pull the connector straight out.
• Pin No. of the Connector (Power supply and output cable for the digital pressure switch and pilot valve)

Internal circuit and wiring example

• NPN output type
  NPN open collector 2 outputs(OUT1:General purpose, OUT2: Valve control), Max. applied voltage 26.4 VDC, Max. load current 80 mA, Residual voltage 2 V or less

• PNP output type
  PNP open collector 2 outputs(OUT1:General purpose, OUT2: Valve control), Max. load current 80 mA, Residual voltage 2 V or less

Easy setting

See below for the energy-saving control operation and the set values which are preset to the switch.

If the operation shown below does not cause any problems, keep these settings.

Operation of OUT1

• When the pressure exceeds the set value (P_1), the pressure switch turns ON.
• When the pressure decreases below the set value (P_1) by the hysteresis value (H_1), the switch turns OFF.
• The default settings are P_1: -70.0 kPa and H_1:10.0 kPa.

Operation of OUT2
Supply pilot valve: OUT2 is turned on by the signal for suction. Suction starts by the generation of vacuum pressure.

When the vacuum pressure reaches the set value (P_1), the supply pilot valve turns OFF. After the supply pilot valve is turned off, the vacuum pressure will decrease, when the vacuum pressure drops below (P_1) by the amount set in (P_2) the supply pilot valve will turn on again and increase vacuum pressure.
After that, the supply pilot valve will turn ON and OFF repeatability. The default setting is H_2: 5.0 kPa.

• When turning off the supply pilot valve with a vacuum pressure that is higher than the set value (P_1), and other setting methods, refer to the operation manual which can be obtained from the SMC website (URL http://www.smcworld.com).

Troubleshooting

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

the power off and remove the cause of the overcurrent.

Then turn the power on.

Zero-clear Error| | During the zero clear operation, pressure above ±3.5%F.S. 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.

Pressurizing Error

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

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

| Pressure has exceeded the lower limit of the set pressure range.
System Error| | Displayed in the case of an internal data error.| 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.
