G9SX USER'S GUIDE

Introduction

This User’s Guide describes the usage of the G9SX Series-Flexible Safety Units mainly through application examples.

Humans make mistakes and machines fail. Therefore it is necessary to design machines and equipment based on the assumption that humans will make mistakes and machines will fail. Thus, a circuit configuration is required to ensure safety, even when an onsite operator makes a mistake in machine operation or when a part of the machine fails. Flexible Safety Units, which enable various safety circuit patterns to be configured only by simple wiring, provide the core components of such safety circuits.

Use the OMRON Flexible Safety Units in your machine and equipment to improve the safety designs and onsite worker safety measures.

Note: 1. The OFF-delay time can be set in 16 steps as follows:

T15: 0/0.2/0.3/0.4/0.5/0.6/0.7/1/1.5/2/3/4/5/7/10/15 s T150: 0/10/20/30/40/50/60/70/80/90/100/110/120/130/140/150 s

2. The OFF-delayed output becomes an instantaneous output by setting the OFF-delay time to 0 s.

3. P channel MOS FET transistor output

4. PNP transistor output

2-1 Logical AND Connection

When connecting two or more Units using a logical AND connection, the logical AND connection setting is performed on the Unit on the input side. Set the logical AND connection preset switch on the Unit that is on the input side (G9SX-AD322 in the below diagram) to AND.

1. When the G9SX-AD/-NS/-NSA/-GS Is on the Input Side

Note: 1. In the above diagram, a setting error will occur and G9SX-AD322 will set a lock out if the logical AND setting switch on G9SX-AD322 is set to OFF.

Set the switch carefully.

2. Set the logical AND setting switch on Unit A to OFF.

3. A logical AND input cannot be input to the G9SX-BC.

2. When the G9SX-ADA Is on the Input Side

Note: 1. When not connecting Unit B, leave terminals T41 and T42 of the G9SX-ADA222 Unit open, and set the logical AND setting switch T41/T42 to OFF.

2. When not connecting Unit C, leave terminals T51 and T52 of the G9SX-ADA222 Unit open, and set the logical AND setting switch to OFF.

When connecting multiple Units to the input side, follow the wiring example in the following diagram.

Note: When a logical AND connection is not used, keep the logical AND connection inputs (terminals T41, T42, T51, and T52) and logical AND connection

outputs (terminals L1 and L2) open, and set the logical AND setting switch to OFF.

(Expansion Units cannot be connected to the G9SX-BC or to the G9SX-NS Non-contact Door Switch Controller.)

• A maximum of five Expansion Units can be connected to one Advanced Unit. This may be a combination of G9SX-EX Instantaneous types and G9SX-EX-T OFF-delayed types.

• Remove the end connector from the Unit (G9SX-AD, G9SX-ADA, G9SX-NSA, or G9SX-GS) and insert the connector on the Connecting Cable from the first Expansion Unit. Place the end connector that was removed from the Unit on the last Expansion Unit (i.e., the rightmost Expansion Unit).

• When Expansion Units are connected to an Advanced Unit, make sure that power is supplied to every Expansion Unit. (Refer to the following diagram for actual Expansion Unit connection.)

2. Logical AND Connections

The logical AND connection is used to build logic between multiple safety inputs and safety outputs. This technology is unique to the G9SX Series.

■ Logical AND Connection Signals

Pulse signals are used in the G9SX logical AND connection and dynamic processing is used to monitor the signals. Information on safety between Units is passed by these pulse signals, which are also used to detect faults in the connection and short circuits.

For this reason, up to safety category 4 can be achieved without redundant logical AND connection signal lines.

■ Insulation

The logical AND connection input section of the G9SX is insulated. Therefore, even when the G9SX logical AND connection cable is configured across multiple devices, it is not necessary to use a shared power source.

■ Simplifying Safety Circuits

Safety circuits were traditionally built by combining relay contacts, but now the logical AND connections of the G9SX simplify building safety circuits. A safety system will be described in which the power is turned ON when safety input 1 and safety input 2 are simultaneously input.
