FPBS Laser safety protection device dedicated to bending machine

FPBS Laser safety protection device dedicated to bending machine  ►

FPBS is jointly developed by Nanjing ESTUN and Germany FIESSLER Company. It is a professional safety protection device specific to Chinese safety standards for bending machine. Twenty-year experience of ESTUN in forging industry and professional development guarantee the applicability of FPBS.Germanymanufacturer guarantees the excellent quality of FPBS. FPBS can be installed on bending machine easily with the help of special installation support to protect the front part of bending machine and operator and prevent accident.

SAFE100 Safety control module 

 Safety  functions

• Redundant loop, dual CPU control

• Connection fault detection
• Input fault detection Detect the fault of input channel via    detecting impulse signal
• Output fault detection
• Backup and detection of key data


SAFE100 safety module is a special safety module developed subject to CE safety product standards. It has complete self-diagnosis function and input/output loops and CPU are dualredundant-structured so the safety function would not fail when single loop  breaks down. It has impulse detection power so it can detect circuit fault automatically and indicate output state.



Signal port

Action mode

Instant stop monitoring

IN1, IN2


Oil pump stops and machine tool stops running.

Side door monitoring

IN3, IN4


Slider can descend slowly (<20mm/S)

Back door monitoring

IN07, IN08


Oil pump stops and machine tool stops running.

Pedal monitoring

IN13, IN14


Pedals in three position. Pedal on upper position stops, pedal on middle position works and pedal on lower position stops.

Mode monitoring

IN17, IN18


Single mode, slider working normally; adjustment mode, slider slowing down in the whole course.

Detection mode

IN15, IN16, IN19


Signal accesses and machine tool enters continuous detection mode.

Safe output

O1, O2

Dual redundant output

Instant stop and back door protection are triggered and output stops.
