The Centurion is a positive mode, thumbwheel operated machine

guard locking interlock switch that locks the guard closed until the

operator manually rotates the thumbwheel, retracting the shaft from

the guard door. 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.

Contact Operation

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.

Note: The safety contacts of the Guardmaster switches are described as normally

closed (N.C.) i.e., with the guard closed, actuator in place (where relevant) and the

machine able to be started.

Note: Additional safety m easures (i.e., a shroud) should be used

to ensure the thum bwheel can only be accessed by finger tips.
