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: Manipulating industrial robots - Safety. etc.

• 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 indicates a hazard with a low level of risk which, if not avoided, could result in minor or moderate injury.
	Warning indicates a hazard with a medium level of risk which, if not avoided, could result in death or serious injury.
	Danger indicates a hazard with a high level of risk which, if not avoided, will result in death or serious injury.

• 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.

• Provide grounding to assure the safety and noise resistance of the Fieldbus system.
  Individual grounding should be provided close to the product using a short cable.
• When conformity to UL is required the SI unit must be used with a UL1310 Class 2 power supply.

Name and function of parts

Installation

Installation

• Do not install the product unless the safety instructions have been read and understood.

• General instructions on installation and maintenance
  Connect the valve manifold to the SI unit.
• Assembly and disassembly of the SI unit
  

Replacement of the SI unit

• Remove the M3 hexagon screws from the SI unit and release the SI unit from the valve manifold.
• Replace the SI unit.
• Tighten the screws with the specified tightening torque. (0.6 N•m)

Assembly Precautions

• Be sure to switch off the power.
• Check there is no foreign matter inside the SI unit.
• Check there is no damage and no foreign matter stuck to the gasket.
• Be sure to tighten the screws with the specified torque.
• If the SI unit is not assembled properly, the internal PCBs may be damaged or liquid and/or dust may enter into the unit.

Connecting Cables

Select the appropriate cables to mate with the connectors mounted on the SI unit.

Fieldbus interface connector layout

BUS OUT: M12 4-pin socket, D-coded (SPEEDCON)

BUS IN: M12 4-pin socket, D-coded (SPEEDCON)

Power supply connector layout

PWR: M12 5-pin plug, A-coded (SPEEDCON)

• The power supply for the solenoid valve and SI unit operation are isolated. Be sure to supply power respectively.
  Either single source power or two different power supplies can be used.

NOTE
When conformity to UL is required the SI unit must be used with a UL1310 Class 2 power supply.

The M12 connector cable for fieldbus and power supply connections has two types, Standard M12 and SPEEDCON compatible. If both plug and socket have SPEEDCON connectors, the cable can be inserted and connected by turning it a 1/2 of a rotation, leading to a reduction in man hours.
A standard connector can be connected to a SPEEDCON connector.

• Be sure to fit a seal cap (EX9-AWTS) on any unused connectors. Proper use of the seal cap enables the enclosure to maintain IP67 specification.

Ground Terminal

• Connect the ground terminal to ground.
• Individual grounding should be provided close to the product with a short cable to assure the safety and noise resistance of the Fieldbus system.
• Resistance to ground should be 100 ohms or less.

Environment

• Do not use in an environment where corrosive gases, chemicals, salt water or steam are present.
• Do not install in a location subject to vibration or impact in excess of the product's specifications.

Setting

Configuration

• Auto-increment addressing can be used to address each slave device according to its physical position in the communication ring and does not require local manual address setting.
• To configure the EX260 SI unit with the EtherCAT master, an XML Device Description File is required.
• Technical documentation giving detailed configuration information and the XML file can be found on the SMC website (URL: https://www.smcworld.com)

Output number assignment

Output numbering starts at zero and refers to the solenoid position on the manifold.
