Example: Using the Enabling Switch in an Assembly Robot Line
To ensure safe operation in an assembly robot line, be sure to establish an overall equipment safety policy in
line with the ISO 13849 safety category.
Assuring safe operation involves installing various safety equipment, and robots must be taught at the time that
production lines are set up. Humans must also sometimes perform tasks in hazardous areas. The procedure
below describes how to use the enabling switch when bringing a device such as the NSH5 close to a robot to
perform operations.
1. Hold the NSH5 (5 in the diagram) enabling switch in the middle position.
2. Turn the enable mode switch (4) from normal mode to enable mode. While teaching, the door interlock
3. Carry the NSH5 into the hazardous area and perform the operation.
4. If either the enabling switch or the emergency stop switch is actuated during operation, use the reset switch
5. The emergency stop switch (2) is always enabled.
Block Diagram When a Relay Unit Is Used
1. In normal mode, safety line 1 is enabled, and the door interlock switch (1) is enabled by the Safety Relay
2. Enable Safety Relay Unit 2 by holding the NSH5’s enabling switch in the middle position.
3. Turn the enable mode switch (4) from normal mode to enable mode, and switch from safety line 1 to safety
4. Always keep the emergency stop switch (2) ready to operate.
5. If either the enabling switch or the emergency stop switch is actuated during operation, use the reset switch

• It restricts the personnel doing the teaching to those who have a key.
• It makes personnel conscious of teaching and entering a hazardous area.
• Operations from outside are disabled while teaching is in progress.
• The door interlock switch signal (1) can be controlled by the enabling switch.
• The disable monitor lamp is lit to let other personnel in the area know that teaching is in progress.
