①Install the SAFETY RELAY BOX to the CONTROLLER for use the SAFETY RELAY BOX. The Safety Relay
"a" contacts switch the Motor Power Line and "b" (*1) contacts switch the external outputs to the machining
center's CNC controller.
②The Safety Relay utilizes Normally Open contacts. The Emergency Stop Signal lines must be supplied with
power to hold the Safety Relay contacts closed and allow the CONTROLLER to supply power to the motor.
Any system errors, trouble with the machining center or the connections between the CONTROLLER and the
machining center's controller will cause the relay contacts to open and the motor to stop.
③The Emergency Stop Signal Input can be connected to any and all portions of the machine's safety systems
(E-Stop String) to stop the motor any time that stoppage of the spindle and motor is required.
④The "b" contact outputs can be used to detect an open circuit on the motor line and integrated with the
machines safety systems to stop the machine in case a problem occurs.
