Improved operator safety on machines with variable run down times can be provided by Guardmaster’s new CU3 stop motion detector. With this new design, Guardmaster says there is no need to mount sensors onto moving parts of machines, saving on engineering time and reducing costs.
The CU3 detects the motion of single or three phase motors by measuring their back EMF. When the supply is disconnected and the motor stops, the CU3’s safety outputs close, enabling an output device such as a solenoid locking switch to be de-energised and a guard to be opened.
