Safety can be ensured, but there is a risk of human error

occurring during operation.

From

Guard Lock Safety-door Switch only

Guard Lock Safety-door Switch

Key Selector Switch (A22K)

When only the Door Switch is used, the operator is at risk of being

shut inside the barrier if, for example, he/she forgets to remove the

trapped key and a third party locks the door.

The safety level is enhanced by switching to maintenance mode.

However, because two different types of keys are required,

the operator is still at risk of being shut inside if he/she forgets to

remove the trapped key.

The equipment may also be started up while the operator is inside.

By using a common key, the risk of human error is reduced in operations

from when the door is open/shut until the equipment is started.

Guard Lock Safety-door Switch

Safety Key Selector Switch (A22TK)

The two locks on the door and equipment use the same key, reducing the likelihood that the user will forget to remove it.

In addition, the key cannot be removed when maintenance is being performed. This prevents the key from being lost and greatly

reduces the risk of an operator becoming trapped inside.
