Remote On/Off Control - Universal Robots UR3/CB3 Original Instructions Manual

5.3.7 Remote ON/OFF control

Remote ON/OFF control can be used to turn the control box on and off without using the teach
pendant. It is typically used in the following applications:
• When the teach pendant is inaccessible.
• When a PLC system must have full control.
• When several robots must be turned on or off at the same time.
The remote ON/OFF control provides a small auxiliary 12V supply, which is kept active when the
controller box is turned off. The "on" and "off" inputs are intended for short time activation only.
The "on" input works in the same way as the power button. Always use the "off" input for remote
"off" control as this signal allows the control box to save open files and shut down correctly.
The electrical specifications are shown below.
The following examples show how to use remote ON/OFF.
