What is an interlocked guard?

Interlocked. When this type of guard is opened or removed, the tripping mechanism and/or power automatically shuts off or disengages, the moving parts of the machine are stopped, and the machine cannot cycle or be started until the guard is back in place.

Interlocking devices with guard locking function A separate status detection, which detects the position of the guard locking device, and generates a corresponding output signal which is used for control purposes, is a component of a guard locking device.

Beside this, How does a safety interlock work?

When a program is in operation, power is applied to the solenoid in the interlock switch, which locks the key inside the switch and locks the door. When the program stops, power is removed, the solenoid is de-energized, and the key is unlocked, which allows the door to open.

Likewise, What is adjustable guard?

Adjustable guards, like fixed guards, are permanent, but they can be adjusted to allow the machine to handle different sizes of material. They must be manually adjusted and locked into place, so all employees who will operate adjustable guards must be trained on their use.

Also, What do Guards do to protect the worker?

Guards are materials that keep workers from having direct contact with moving parts and other dangerous areas of a machine. Some guards also protect workers from shavings, flying shards or metal sparks created by working machines.

What is meant by machine guarding?

The purpose of machine guarding is to protect the machine operator and other employees in the work area from hazards created during the machine’s normal operation. This would include hazards of concern such as: ingoing nip points, rotating parts, reciprocating, transversing, and/or flying chips & sparks.
