Interlock Switches Guard Locking Switches Centurion Specifications Standards EN954-1, ISO13849-1, IEC/EN60204-1, NFPA79, EN1088, ISO14119, IEC/ EN60947-5-1, ANSI B11.19, AS4024.1 Category Cat. 1 Device per EN954-1 Dual channel interlocks suitable for Cat. 3 or 4 systems Approvals CE marked for all applicable directives, cULus, BG, and SUVA Safety Contact 2 N.C. direct opening action Designation/Utilization Cat. AC15 AC (Ue) 500V 250V 100V (Ie) 1A 2A 5A DC 250V 0.5A 24V 2A 73013 Max Switched Current/Volt/ 500V/500VA Load Description Thermal Current (lth) 10A The Centurion is a positive mode, thumbwheel operated machine guard locking interlock switch that locks the guard closed until the Min Current 5V 5mA operator manually rotates the thumbwheel, retracting the shaft from Safety Contact Gap >2mm (0.078in) the guard door. The action of retracting the shaft initiates two Rtd. Insulation Voltage (Ui) 500V functions it isolates the power to the machine while the guard is open Rtd. Impulse withstand Volt (Uimp) 2500V and, due to the operating principle, gives up to 20 seconds delay before the guard can be opened. Auxiliary Contacts 1 N.C. Shaft Movement to Achieve 2mm (0.078in) Alternative styles with longer shafts can increase the time delay by as Contact Operation much as 50%. The Centurion is ideal for use on simple machines Case Material Heavy duty die cast alloy with short, constant run down times. It is important that correct Locking shaft Stainless Steel installation and operation of the unit are followed to ensure that the retractable shaft cannot be extended when the guard is open. For Protection IP66 machines with long or variable run down times or where frequent Conduit Entry 1 x M20 or quick disconnect access is required, solenoid locking switches such as the TLS-GD2 Operating Temperature -25C to +80C (-10F to +176F) and Atlas 5 should be considered. Mounting 2 x M4 The Centurion has 2 safety (N.C.) contacts, 1 auxiliary (N.O.) contact Mechanical Life 1,000,000 operations and 1 conduit entry (either M20 or quick disconnect). Electrical Life 1,000,000 operations EX and Pneumatic styles of the Centurion are also available see the Weight 500g (1.20lbs) Explosion Proof section on page 16-1 for more information. Colour Red Note: The safety contacts of the Guardmaster switches are described as normally Note: Additional safety measures (i.e., a shroud) should be used closed (N.C.) i.e., with the guard closed, actuator in place (where relevant) and the to ensure the thumbwheel can only be accessed by fingertips. machine able to be started. Centurion Thumbwheel Operation Features Manually operated time delay, allows for machine run down Simple operation & installation Robust die cast housing, ideal for heavy duty applications Contacts, 2 N.C. & 1 N.O. (sealed to IP66) Interlocking shaft is manually retracted from the guard by rotating the thumbwheel. 3-4011 12 21 22 33 34 Interlock Switches Guard Locking Switches Centurion Product Selection Catalogue Number Safety Contacts Auxiliary Contacts BBM/MBB Type M20 Conduit Quick Disconnect Right Hand 440K-B04025 440K-B04046 Left Hand 440K-B04026 440K-B04047 2 N.C. 1 N.O.
