3 Safety Precautions

!WARNING

Serious injury may possibly occur due to loss of required safety functions. Do not use test outputs of the DST1 as any safety outputs.

Serious injury may possibly occur due to loss of required safety functions. Do not use DeviceNet standard I/O data or Explicit message data as any safety data.

Serious injury may possibly occur due to loss of required safety functions. Do not use LEDs on the DST1 for safety operations.

Serious injury may possibly occur due to breakdown of safety outputs. Do not connect loads beyond the rated value to the safety outputs.

Serious injury may possibly occur due to loss of required safety functions. Wire the DST1 properly so that 24-VDC line do NOT touch the safety outputs accidentally or unintentionally.

Serious injury may possibly occur due to loss of required safety functions. Ground the 0V line of the power supply for external output devices so that the devices do Not turn ON when the safety output line is grounded.

For the DST1-MRD08SL-1, isolating transformers, such as TR1, that are used to isolate between overvoltage categories III and II must conform to IEC60742, and the insulation between the primary input and secondary output must satisfy at least the basic insulation standards of overvoltage category III. One side of the secondary output of the isolating transformer must be grounded to prevent electrical shock in case of short-circuiting to the ground or to the frame of the isolating transformer. To protect the isolating transformer and to prevent electrical shock in case of short-circuiting to the frame, insert fuses according to transformer specifications, i.e. at points F1, F2, and F3.

!WARNING

Serious injury may possibly occur due to loss of required safety functions. Clear the previous configuration data before connecting devices to the network.

Serious injury may possibly occur due to loss of required safety functions. Set suitable node addresses before connecting devices to the network.

Serious injury may possibly occur due to loss of required safety functions. Perform user testing and confirm that all device configuration data and operations are correct before starting system operation.

Serious injury may possibly occur due to loss of required safety functions.When replacing a device, configure the replacement device appropriately and confirm that it operates correctly.

For Model DST1-MRD08SL-1, insert a fuse rated at 3.15 A or less for each output terminal to protect safety output contacts from welding. Confirm the fuse selection with the fuse manufacturer to ensure the dependability of the characteristics of the connected load.

Serious injury may possibly occur due to loss of safety functions. Use appropriate devices according to the requirements given in the following table.

Control device	Requirements
Emergency stop switches	Use approved switches with a direct opening mechanism complying with
	IEC/EN 60947-5-1.
Door interlocking switches	Use approved switches with a direct opening mechanism complying with
Limit switches	IEC/EN 60947-5-1 and capable of switching micro-loads of 5 mA at 24 V DC.
Safety sensors	Use approved sensors complying with the relevant product standards, regu-
	lations, and rules in the country where it is used.
Relays with forcibly guided	Use approved relays with forcibly guided contacts complying with EN 50205.
contacts	For feedback purpose, use devices with contacts capable of switching micro-
Contactors	loads of 4 mA at 24 V DC.
Other devices	Evaluate whether devices used are appropriate to satisfy the requirements of
	safety category.

4 Operating Environment Precautions

■Handle with Care

Do not drop the DST1 to the ground or excessive vibration or mechanical shocks. The DST1 may be damaged and may not function properly.

■Installation and Storage Environment

Do not use or store the DST1 in any of the following locations.

•Locations subject to direct sunlight.

•Locations subject to temperatures or humidity outside the range specified in the specifications.

•Locations subject to condensation as the result of severe changes in temperature.

•Locations subject to dust (especially iron dust) or salts

•Locations subject to dust (especially iron dust) or salts.

•Locations subject to water, oil, or chemicals.

Operating Environment Precautions

4

• Locations subject to shock or vibration.

Take appropriate and sufficient countermeasures when installing systems in the following locations. Inappropriate and insufficient measures may result in malfunction.

•Locations subject to static electricity or other forms of noise.

•Locations subject to strong electromagnetic fields

•Locations subject to possible exposure to radioactivity.

•Locations close to power supplies.

This is a class A product. In residential areas it may cause radio interference, in which case the user may be required to take adequate measures to reduce interference.

■Installation/Mounting

•Use the DST1 within an enclosure with IP54 protection or higher of IEC/ EN 60529.

•Use DIN rail (TH35-7.5 according to IEC60715) for placing the DST1 into the control board.

•Mount the DST1 to DIN rails with attachments (TYPE PFP-M, not incorporated to this product), not to drop out of rails by vibration etc.

•Spacing should be available around the DST1 at least 50 mm from its top and bottom surfaces for ventilation and wiring.

■Installation/Wiring

•Use the following to wire external I/O devices to the DST1.

Solid wire	0.2 to 2.5 mm2 AWG 24 to 12
Standard (Flexible)	0.34 to 1.5 mm2 AWG 22 to 16
wire	Standard wire should be processed with insulation-covered
	bar terminal (DIN46228-4 standard compatible type) at its
	ends before using for connection.

•Disconnect the DST1 from power supply when wiring. Devices connected to DST1 may operate unexpectedly.

•Apply properly specified voltages to the DST1 inputs. Applying inappropriate DC voltage and any AC voltages cause the DST1 to fail.

•Be sure to separate the communication cable and the I/O cable from the high-voltage/ current lines.

•Be cautious not to have your fingers caught when attaching connectors to the plugs on the DST1.

•Mount screw of DeviceNet Connector and I/O Connector correctly. (0.25- 0.3 N·m)

•Incorrect wiring may lead to loss of safety function. Wire conductors correctly and verify the operation of the DST1 before commissioning the system in which DST1 is incorporated.

•After wiring is completed, be sure to remove label for wire clipping prevention on the DST1 to enable heat to escape for proper cooling

1-1-1 About the DST1-series Safety I/O Terminals

The DST1-series Safety I/O Terminals support the DeviceNet Safety protocol and provide various functions for the Safety System. The DST1-series Safety I/O Terminals allow the user to construct a safety control/network system that meets the requirements for Safety Integrity Level (SIL) 3 according to IEC 61508 (Functional Safety of Electrical/Electronic/ Programmable Electronic Safety-related Systems) and the requirements for Safety Category 4 according to EN 954-1.

The DST1-series Safety I/O Terminal’s safety I/O data is transmitted through safety I/O communications conforming to the DeviceNet Safety Protocol, and the data processing is performed in conducted in the Safety Network Controller (NE1A-SCPU01).

Also, the status of the safety I/O data can be monitored in a standard PLC in an existing DeviceNet network using standard I/O communications or explicit message communications.

The DST1-XD0808SL-1 Logic Terminal has built-in logic functions. This enables direct control of local outputs from local inputs, allowing reaction time to be shortened.

The following status is treated as the safe state by the DST1-series Safety I/O

Terminals.

•Safety outputs: OFF

•Output data to network: OFF

Outputs to network: OFF

Safe state

Inputs

Outputs: OFF

Therefore, the DST1-series Safety I/O Terminals must be used for applications in which it enters into safe state when the safety outputs turn OFF and the output data to the network turns OFF.

Self-diagnosis Functions

Self-diagnosis is performed when the power is turned ON and periodically during operation. If an error occurs, it will be treated as a fatal error (the MS indicator will light in red), and the safety outputs and output data to the network will turn OFF.

Access Control by Password

After configuration data had been downloaded and verified, the configuration data within the DST1-series Safety I/O Terminals can be protected by a password.
