Nortech Systems RS-422/485 User Manual

To re-enable High Power after pressing the MCP emergency stop switch, follow this 
process:

1. Turn the emergency stop switch to the right (clockwise). The switch is spring 

loaded and will return to its normal position. 

2. Depress the enabling switch. High Power can now be re-enabled by pressing the 

COMP/PWR button (mode control group), or by entering the ENABLE POWER 
command from the keyboard.

3. Press the blinking High Power button on the Front Panel (or CIP2 in an MV 

controller system). High Power is enabled and current can flow to the robot 
motors.

When the system is operating in Automatic Mode and you release the Enable switch (or 
go to position 3 in the 3-position switch), the system turns off the same as an E-stop 
condition. To re-enable high power you must follow the steps from the previous section.

In a CAT-3 SmartController, when operating in Automatic Mode, the Enable Switch is 
ignored by the system. Releasing the Enable switch has no effect on operation. See 

 for more information.

When the system is operating in Manual Mode and you release the Enable switch (or go to 
position 3 in the 3-position switch), the system turns off in a controlled manner. This puts 
the system in a different state than when the E-Stop button is pressed. To re-enable high 
power, follow this process:

1. Turn the emergency stop switch to the right (clockwise). The switch is spring 

loaded and will return to its normal position. 

2. Depress the enabling switch. High Power can now be re-enabled by pressing the 

COMP/PWR button (mode control group), or by entering the ENABLE POWER 
command from the keyboard. High Power is enabled and current can flow to the 
robot motors. This makes it more convenient during development and 
programming a system.

NOTE: The exception to this situation is when a CAT-3 SmartController is 
used in a SmartModules system with a PDU-2. You have to press the 
blinking High Power button on the Front Panel.
