The action of retracting the shaft initiates two functions; it isolates the power to the machine while the guard is open and, due to the operating principle, gives up to 20 seconds delay before the guard can be opened. Thermal Current (lth) 10A Min Current 5V 5mA Safety Contact Gap >2mm (0.078in) Auxiliary Contacts 1 N.C. Alternative styles with longer shafts can increase the time delay by as much as 50%. The Centurion is ideal for use on simple machines with short, constant run down times. It is important that correct installation and operation of the unit are followed to ensure that the retractable shaft cannot be extended when the guard is open. For machines with long or variable run down times or where frequent access is required, solenoid locking switches such as the TLS-GD2 and Atlas 5 should be considered. Shaft Movement to Achieve Contact Operation 2mm (0.078in) 73013 Description The Centurion has 2 safety (N.C.) contacts, 1 auxiliary (N.O.) contact and 1 conduit entry (either M20 or quick disconnect). EX and Pneumatic styles of the Centurion are also available; see the Explosion Proof section on page 16-1 for more information. Note: Additional safety measures (i.e., a shroud) should be used to ensure the thumbwheel can only be accessed by fingertips. Features • • • • Rtd. Insulation Voltage (Ui) 500V Rtd.
