Punching Machine Safety Light Curtain

ESA series is mainly used for safety protection for stamping machinery, which adopt controller to monitor and output signal of light curtains.
ESA series supports AV110-220V, AC380V voltage and output relay signal. ESA series is designed according to EU safety standard, whose main components are imported.
Good self-diagnosis, easy to operation, and strong anti-vibration ability make ESA series can work in different hazardous equipment, and well protect operators from accident.
 

Model :
 






 

• AC110V-220V, AC380V wide voltage for stamping machinery;
• Controller reliably monitor signal of light curtain by pulse detection method, which effectively ensure that mistake signal will not be triggered when short circuit;
• Good performance to against electromagnetic interference of different machine motor;
• Anti-shock circuit and strong aluminum alloy enclosure well against vibration;
• Wire-syn good to against light interference;
• Controller output signal by relay isolation output mode, and the external control signal is completely isolated form internal circuit of barriers;
• Plug connecting between curtain & controller make wire connection easily and quickly,
• Multiple brackets for various environment mounting;
• One controller can work with more sets of safety light curtain for multi-faced protection;
• Long sensing distance up to 20m.

Wire Diagram :

• External Controller (P-Type)
  • L (brown) and N (blue) is input wire of AC110V/220V, please check and ensure right connection;
  • T (brown) and K (blue) should be connected with control circuit of machine shown as below. When beams are through, T&K are connected and the machine works well; When beams are blocked, T&K are disconnected to stop the machine.
    
    
• Internal Controller (Q)
  • Connection of T.K wire, under normal circumstance, Return No Protection no need);
  • Connection of T.K (need Return No Protection), Return No Protection function is usually achieved by machine, no need to connect additionally.
  • When it needs to be achieved by safety light curtain, you can connect wire as below method.
  • A pair of normally open contacts of the cam are connected in parallel with Tand K.

Controller Options : 

• Please check if light curtain control machine well before working and refer to step 4 to debug.
• Avoid movement of safety light curtain casually;
• The key of controller should be kept by professional engineers;
• Engineers need to adjust the sensing distance and position of light curtain after changing machine model;
• Power Supply should be cut off by professional operators when dissemble and maintain light curtain;
• 100 million times, reaching the service life, or after three years of use, it should be replaced:
• During use, be careful not to let workpieces, tools, wastes and other items collide with the photoelectric protection device.
• Push reset button to re-start machine, if curtains connected with reset button, and machine stop after beam blocked.
