Failure:

Termination of the ability of an item to perform a required function

Note 1: After failure the item has a fault
Note 2: "Failure" is an event, as distinguished from"fault", which is a state.

Note 3: This concept, as defined, does not apply to items consisting of software only.

Note 4: In practice,the term fault and failure are often used synonymously

Self-checking:

The device switches automatically into the "safe state" when it is faulty

.

Standard Mounting Range:

Maximum distance between transmitter and receiver is 5 m, if exceed 
the distance may lead to hazardous motion. For longer range please get 
in contact with us.

Overrun Distance:

The distance covered during the overrun (e.g. by the ram of a press).

Start Interlock:

After initial operation or after a power supply interruption a renewed 
"enabling" is blocked by the start interlock.The renewed release of the 
switching unit is only possible by closing and opening of the start entry.

Box Bending Mode:

The E3 is muted during during bending process.

2.2 Usage

SLA-3 is the safety device specially applied to bending machine for 
operator's protection which adpoted class 1 laser, A three-dimension 

laser protective field between the emitter and receiver to form the 

guarding area underneath the clamped upper tool, any intervention into 
the area shuts down the closing movement of the press.
